Developer Tools & Debugging in NgRx

When working on a complex software solution, we often find ourselves scratching our heads over a bug that was reported to us. It's essential to have proper tools to trace the issues which like to hide in our code execution paths. Luckily for the devs using NgRx in their project, the application state is kept in a single location and all the actions that can modify it are easily traceable with some great DevTools. As NgRx adheres to the redux pattern, we can use the same Redux DevTools as we would use for any other Redux base application. This tool is essential for me when debugging an NgRx based application.

If you haven't worked with NgRx yet, I recommend reading this post first where I introduced the NgRx pattern into a simple app.

Getting started

In order to make our NgRx store visible in the Redux DevTools, we need to pull in a module provided by NgRx platform - @ngrx/store-devtools. For the installation instructions, please visit the official installation guide.

After installing the Store Devtools using the AngularCLI schematics, the following code is automatically added to our AppModule:

@NgModule({
  /* other module properties */
  imports: [
    /* other imported modules */
    StoreDevtoolsModule.instrument({
      maxAge: 25, // Retains last 25 states
      logOnly: environment.production, // Restrict extension to log-only mode
    }),
  ],
})

maxAge property is limited to 25 by default for performance reasons - this is the limit of actions stored in the history tree.

logOnly is usually set to true on production build to limit the number of features used when connecting to Redux DevTools.

I suggest adding name property to our initial configuration to more easily find our state in the DevTools (as it will show all the other stores which might be used in other tabs open in the browser).

@NgModule({
  /* other module properties */
  imports: [
    /* other imported modules */
    StoreDevtoolsModule.instrument({
      name: 'DevTools & Debugging in NgRx'
      maxAge: 25, // Retains last 25 states
      logOnly: environment.production, // Restrict extension to log-only mode
    }),
  ],
})

With that minimal setup, we can already start using the Redux DevTools to start debugging our application.

You can access the Redux DevTools in the Redux tab on your browser developers tools. Chrome DevTools - Redux

Tracking actions

The first thing you can do in the Redux DevTools is track all the actions that have been dispatched within the application. Redux DevTools - list of action

For every selected action, you can see the current state value, what exactly has changed in the state as a result of this action, and the content of action object.

Moreover, the extension gives you the possibility to "time travel" your application and skip some of the actions to see how it would affect the end result of the state.

You can either manually select the point in time to jump to or replay the whole sequence of action using timeline at the bottom.

Those functionalities alone provide us with handful of possibilities on tracking how the state of our app is changing over time and pinpointing the possible issues.

Replicating the app behavior

Another very powerful feature of the Redux DevTools is tha posibility to dispatch the actions without the need of interacting with the UI. It's available as one of the tabs in the bottom extension's menu:

By using this feature, we can dispatch any action we want. This is extremely useful if we find the exact course of actions that is leading to an error, but it's hard or long to replicate using the UI. We can enter and dispatch the desired sequence of actions and get to the troublesome point in the app state with ease and in a reproducible manner.

There are a few features that combine well with the aforementioned dispatching technique:

Persisting the state
Commiting and reverting the state

When we select the persist option, the extension makes sure that our state is persisted and restored even after we reload the page. The commit option allows us to store the state at the specific point in time and treat it as a starting point (it's like saving the game before going on to fight with the boss 🤓).

You can perform as many actions as you want from this point on, but you'll always be able to restore the state to a point in time at which you've done a last commit. The restore functionality is only available in the log monitor and not the inspector.

This plays really well with dispatching actions directly from the extension. We can test and debug how our application behaves (ie. via Effects) when dipatching a specific action with always exactly the same comitted state. Also, it's easy to repeat by reverting the state and dispatching the action again.

NgRx Store Dev Tools options

So far we've covered many use-cases of the Redux DevTools, but we can configure it's behavior to our needs when setting up the StoreDevtoolsModule.

In real life applications, our action log might consist of hundreds of actions which might pollute our view of what is happening in the app. We can filter them out directly in the extension but that doesn't solve the issue of the limit on number of actions visible at once. We're still limited by whatever the limit we set, and for performance reasons, we should not take this limit off or set it too high. For debugging purposes, we might only be interested in certain type of actions or definitely know that some actions (ie. the one dispatched by Angular Router) might not be useful to us at the given moment. When setting up our StoreDevtoolsModule we're given 3 ways to filter the actions that will be sent to the Redux DevTools extension:

actionBlocklist
actionSafelist
predicate

The first two are the most common ones to use. We can either block specific patters of actions (which we know that are not of interest to us) or we can allow only certain types of actions. Both of them take an array of strings as a value and act as a regex on action type property to filter out only the ones we're interested in.

If we want to do more specific filtering, we can use predicate. It takes current state and action as parameters and is called for each dispatched action. To allow action to be passed to the Redux DevTools extension, it must return true.

With those techniques, we can narrow the scope of actions visible in the extension and therefore make it easier to get the grasp of what is happening in the app.

Conclusion

With the tools and techniques mentioned above, you should be able to debug your NgRx based application with a bit more ease. It's important to know the tools you have available so that you can use them when the need arises.

Overview of the New Signal APIs in Angular

Overview of the New Signal APIs in Angular Google's Minko Gechev and Jeremy Elbourn announced many exciting things at NG Conf 2024. Among them is the addition of several new signal-based APIs. They are already in developer preview, so we can play around with them. Let's dig into it, starting with signal-based inputs and the new matching outputs API. Signal Based Inputs Discussions about signal-based inputs have been taking place in the Angular community for some time now, and they are finally here. Until now, you used the @Input() decorator to define inputs. This is what you'd have to write in your component to declare an optional and a required input: ` With the new signal-based inputs, you can write much less boilerplate code. Here is how you can define the same inputs using the new syntax: ` It's not only less boilerplate, but because the values are signals, you can also use them directly in computed signals and effects. That, effectively, means you get to avoid computing combined values in ngOnChanges or using setters for your inputs to be able to compute derived values. In addition, input signals are read-only. The New Output I intentionally avoid calling them signal-based outputs because they are not. They still work the same way as the old outputs. The Angular team has just introduced a new output API that is more consistent with the latest inputs API and allows you to write less boilerplate, similar to the new input API. Here is how you would define an output until now: ` Here is how you can define the same output using the new syntax: ` The thing I like about the new output API is that sometimes it happens to me that I forget to instantiate the EventEmitter because I do this instead: ` You won't forget to instantiate the output with the new syntax because the output function does it for you. Signal Queries I am sure most readers know the @ViewChild, @ViewChildren, @ContentChild, and @ContentChildren decorators very well and have experienced the pain of triggering the infamous ExpressionChangedAfterItHasBeenCheckedError or having the values unavailable when needed. Here is a refresher on how you would use these decorators until now: ` With the new signal queries, similar to the new input API, the values are signals, and you can use them directly in computed signals and effects. You can define the same queries using the new syntax: ` Jeremy Elbourn mentioned that the new signal queries have better type inference and are more consistent with the new input and output APIs. He also showcased a brand new feature not available with the old queries. You can now define a query as required, and the Angular compiler will throw an error if the query has no result, guaranteeing that the value won't be undefined. Here is how you can define a required query: ` Model Inputs Jeremy and Minko announced the last new feature is the model inputs. The name is vague, but the feature is cool—it simplifies the definition of two-way bindings. Until now, to achieve two-way binding, you would have to define an input and an output following a given naming convention. @Input and @Output had to be defined with the same name (followed by "Change" in the case of the output). Then, you could use the template's [()] syntax. ` ` That way, you could keep the value in sync between the parent and the child component. With the new model inputs, you can define a two-way binding with a single line of code. Here is how you can define the same two-way binding using the new syntax: ` The html template stays the same: ` The model function returns a writable signal that can be updated directly. The value will be propagated back to any two-way bindings. Conclusion The new signal-based APIs are a great addition to Angular. They allow you to write less boilerplate code and make your components more reactive. The new APIs are already in developer preview, so you can start playing around with them today. I look forward to seeing how the community will adopt these new features and what other exciting things the Angular team has in store for us, such as zoneless apps by default....

Exploring Angular Forms: A New Alternative with Signals

Exploring Angular Forms: A New Alternative with Signals In the world of Angular, forms are essential for user interaction, whether you're crafting a simple login page or a more complex user profile interface. Angular traditionally offers two primary approaches: template-driven forms and reactive forms. In my previous series on Angular Reactive Forms, I explored how to harness reactive forms' power to manage complex logic, create dynamic forms, and build custom form controls. A new tool for managing reactivity - signals - has been introduced in version 16 of Angular and has been the focus of Angular maintainers ever since, becoming stable with version 17. Signals allow you to handle state changes declaratively, offering an exciting alternative that combines the simplicity of template-driven forms with the robust reactivity of reactive forms. This article will examine how signals can add reactivity to both simple and complex forms in Angular. Recap: Angular Forms Approaches Before diving into the topic of enhancing template-driven forms with signals, let’s quickly recap Angular's traditional forms approaches: 1. Template-Driven Forms: Defined directly in the HTML template using directives like ngModel, these forms are easy to set up and are ideal for simple forms. However, they may not provide the fine-grained control required for more complex scenarios. Here's a minimal example of a template-driven form: ` ` 2. Reactive Forms: Managed programmatically in the component class using Angular's FormGroup, FormControl, and FormArray classes; reactive forms offer granular control over form state and validation. This approach is well-suited for complex forms, as my previous articles on Angular Reactive Forms discussed. And here's a minimal example of a reactive form: ` ` Introducing Signals as a New Way to Handle Form Reactivity With the release of Angular 16, signals have emerged as a new way to manage reactivity. Signals provide a declarative approach to state management, making your code more predictable and easier to understand. When applied to forms, signals can enhance the simplicity of template-driven forms while offering the reactivity and control typically associated with reactive forms. Let’s explore how signals can be used in both simple and complex form scenarios. Example 1: A Simple Template-Driven Form with Signals Consider a basic login form. Typically, this would be implemented using template-driven forms like this: ` ` This approach works well for simple forms, but by introducing signals, we can keep the simplicity while adding reactive capabilities: ` ` In this example, the form fields are defined as signals, allowing for reactive updates whenever the form state changes. The formValue signal provides a computed value that reflects the current state of the form. This approach offers a more declarative way to manage form state and reactivity, combining the simplicity of template-driven forms with the power of signals. You may be tempted to define the form directly as an object inside a signal. While such an approach may seem more concise, typing into the individual fields does not dispatch reactivity updates, which is usually a deal breaker. Here’s an example StackBlitz with a component suffering from such an issue: Therefore, if you'd like to react to changes in the form fields, it's better to define each field as a separate signal. By defining each form field as a separate signal, you ensure that changes to individual fields trigger reactivity updates correctly. Example 2: A Complex Form with Signals You may see little benefit in using signals for simple forms like the login form above, but they truly shine when handling more complex forms. Let's explore a more intricate scenario - a user profile form that includes fields like firstName, lastName, email, phoneNumbers, and address. The phoneNumbers field is dynamic, allowing users to add or remove phone numbers as needed. Here's how this form might be defined using signals: ` > Notice that the phoneNumbers field is defined as a signal of an array of signals. This structure allows us to track changes to individual phone numbers and update the form state reactively. The addPhoneNumber and removePhoneNumber methods update the phoneNumbers signal array, triggering reactivity updates in the form. ` > In the template, we use the phoneNumbers signal array to dynamically render the phone number input fields. The addPhoneNumber and removePhoneNumber methods allow users to reactively add or remove phone numbers, updating the form state. Notice the usage of the track function, which is necessary to ensure that the ngFor directive tracks changes to the phoneNumbers array correctly. Here's a StackBlitz demo of the complex form example for you to play around with: Validating Forms with Signals Validation is critical to any form, ensuring that user input meets the required criteria before submission. With signals, validation can be handled in a reactive and declarative manner. In the complex form example above, we've implemented a computed signal called formValid, which checks whether all fields meet specific validation criteria. The validation logic can easily be customized to accommodate different rules, such as checking for valid email formats or ensuring that all required fields are filled out. Using signals for validation allows you to create more maintainable and testable code, as the validation rules are clearly defined and react automatically to changes in form fields. It can even be abstracted into a separate utility to make it reusable across different forms. In the complex form example, the formValid signal ensures that all required fields are filled and validates the email and phone numbers format. This approach to validation is a bit simple and needs to be better connected to the actual form fields. While it will work for many use cases, in some cases, you might want to wait until explicit "signal forms" support is added to Angular. Tim Deschryver started implementing some abstractions around signal forms, including validation and wrote an article about it. Let's see if something like this will be added to Angular in the future. Why Use Signals in Angular Forms? The adoption of signals in Angular provides a powerful new way to manage form state and reactivity. Signals offer a flexible, declarative approach that can simplify complex form handling by combining the strengths of template-driven forms and reactive forms. Here are some key benefits of using signals in Angular forms: 1. Declarative State Management: Signals allow you to define form fields and computed values declaratively, making your code more predictable and easier to understand. 2. Reactivity: Signals provide reactive updates to form fields, ensuring that changes to the form state trigger reactivity updates automatically. 3. Granular Control: Signals allow you to define form fields at a granular level, enabling fine-grained control over form state and validation. 4. Dynamic Forms: Signals can be used to create dynamic forms with fields that can be added or removed dynamically, providing a flexible way to handle complex form scenarios. 5. Simplicity: Signals can offer a simpler, more concise way to manage form states than traditional reactive forms, making building and maintaining complex forms easier. Conclusion In my previous articles, we explored the powerful features of Angular reactive forms, from dynamic form construction to custom form controls. With the introduction of signals, Angular developers have a new tool that merges the simplicity of template-driven forms with the reactivity of reactive forms. While many use cases warrant Reactive Forms, signals provide a fresh, powerful alternative for managing form state in Angular applications requiring a more straightforward, declarative approach. As Angular continues to evolve, experimenting with these new features will help you build more maintainable, performant applications. Happy coding!...

How to Write a Custom Structural Directive in Angular - Part 2

How to write a custom structural directive in Angular - part 2 In the previous article I've shown how you can implement a custom structural directive in Angular. We've covered a simple custom structural directive that implements interface similar to Angular's NgIf directive. If you don't know what structural directives are, or are interested in basic concepts behind writing custom one, please read the previous articlefirst. In this article, I will show how to create a more complex structural directive that: - passes properties into the rendered template - enables strict type checking for the template variables Starting point I am basing this article on the example implemented in the part 1 article. You can use example on Stackblitz as a starting point if you wish to follow along with the code examples. Custom NgForOf directive This time, I would like to use Angular's NgForOf directive as an example to re-implement as a custom CsdFor directive. Let's start off by using Angular CLI to create a new module, and directive files: ` First, we need to follow similar steps as with the CsdIf directive. - add constructor with TemplateRef, and ViewContainerRef injected - add an @Input property to hold the array of items that we want to display ` Then, in the ngOnInit hook we can render all the items using the provided template: ` Now, we can verify that it displays the items properly by adding the following template code to our AppComponent. ` It displays the items correctly, but doesn't allow for changing the displayed collection yet. To implement that, we can modify the csdForOf property to be a setter and rerender items then: ` Now, our custom directive will render the fresh items every time the collection changes (its reference). Accessing item property The above example works nice already, but it doesn't allow us to display the item's content yet. The following code will display "no content" for each template rendered. ` To resolve this, we need to provide a value of each item into a template that we are rendering. We can do this by providing second param to createEmbeddedView method of ViewContainerRef. ` The question is what key do we provide to assign it under item variable in the template. In our case, the item is a default param, and Angular uses a reserved $implicit key to pass that variable. With that knowledge, we can finish the renderItems method: ` Now, the content of the item is properly displayed: Adding more variables to the template's context Original NgForOf directives allows developers to access a set of useful properties on an item's template: - index - the index of the current item in the collection. - count - the length of collection - first - true when the item is the first item in the collection - last - true when the item is the last item in the collection - even - true when the item has an even index in the collection - odd - true when the item has an odd index in the collection We can pass those as well when creating a view for a given element along with the $implicit parameter: ` And now, we can use those properties in our template. ` Improve template type checking Lastly, as a developer using the directive it improves, the experience if I can have type checking in the template used by csdFor directive. This is very useful as it will make sure we don't mistype the property name as well as we only use the item, and additional properties properly. Angular's compiler allows us to define a static ngTemplateContextGuard methods on a directive that it will use to type-check the variables defined in the template. The method has a following shape: ` This makes sure that the properties of template rendered by our DirectiveClass will need to conform to DirectiveContext. In our case, this can be the following: ` Now, if we eg. try to access item's property that doesn't exist on the item's interface, we will get a compilation error: ` The same would happen if we made a typo in any of the context property names: ` Summary In this article, we've created a clone of Angular's built-in NgForOf directive. The same approach can be used to create any other custom directive that your project might need. As you can see, implementing a custom directive with additional template properties and great type checking experience is not very hard. If something was not clear, or you want to play with the example directive, please visit the example on Stackblitz. In case you have any questions, you can always tweet or DM me at @ktrz. I'm always happy to help!...

Docusign Momentum 2025 From A Developer’s Perspective

*What if your contract details stuck in PDFs could ultimately become the secret sauce of your business automation workflows?* In a world drowning in PDFs and paperwork, I never thought I’d get goosebumps about agreements – until I attended Docusign Momentum 2025. I went in expecting talks about e-signatures; I left realizing the big push and emphasis with many enterprise-level organizations will be around Intelligent Agreement Management (IAM). It is positioned to transform how we build business software, so let’s talk about it. As Director of Technology at This Dot Labs, I had a front-row seat to all the exciting announcements at Docusign Momentum. Our team also had a booth there showing off the 6 Docusign extension apps This Dot Labs has released this year. We met 1-on-1 with a lot of companies and leaders to discuss the exciting promise of IAM. What can your company accomplish with IAM? Is it really worth it for you to start adopting IAM?? Let’s dive in and find out. After his keynote, I met up with Robert Chatwani, President of Docusign and he said this > “At Docusign, we truly believe that the power of a great platform is that you won’t be able to exactly predict what can be built on top of it,and builders and developers are at the heart of driving this type of innovation. Now with AI, we have entered what I believe is a renaissance era for new ideas and business models, all powered by developers.” Docusign’s annual conference in NYC was an eye-opener: agreements are no longer just documents to sign and shelve, but dynamic data hubs driving key processes. Here’s my take on what I learned, why it matters, and why developers should pay attention. From E-Signatures to Intelligent Agreements – A New Era Walking into Momentum 2025, you could feel the excitement. Docusign’s CEO and product team set the tone in the keynote: “Agreements make the world go round, but for too long they’ve been stuck in inboxes and PDFs, creating drag on your business.” Their message was clear – Docusign is moving from a product to a platform. In other words, the company that pioneered e-signatures now aims to turn static contracts into live, integrated assets that propel your business forward. I saw this vision click when I chatted with an attendee from a major financial services firm. His team manages millions of forms a year – loan applications, account forms, you name it. He admitted they were still “just scanning and storing PDFs” and struggled to imagine how IAM could help. We discussed how much value was trapped in those documents (what Docusign calls the “Agreement Trap” of disconnected processes). By the end of our coffee, the lightbulb was on: with the right platform, those forms could be automatically routed, data-extracted, and trigger workflows in other systems – no more black hole of PDFs. His problem wasn’t unique; many organizations have critical data buried in agreements, and they’re waking up to the idea that it doesn’t have to be this way. What Exactly is Intelligent Agreement Management (IAM)? So what is Docusign’s Intelligent Agreement Management? In essence, IAM is an AI-powered platform that connects every part of the agreement lifecycle. It’s not a single product, but a collection of services and tools working in concert. Docusign IAM helps transform agreement data into insights and actions, accelerate contract cycles, and boost productivity across departments. The goal is to address the inefficiencies in how agreements are created, signed, and managed – those inefficiencies that cost businesses time and money. At Momentum, Docusign showcased the core components of IAM: - Docusign Navigator link: A smart repository to centrally store, search, and analyze agreements. It uses AI to convert your signed documents (which are basically large chunks of text) into structured, queryable data. Instead of manually digging through contracts for a specific clause, you can search across all agreements in seconds. Navigator gives you a clear picture of your organization’s contractual relationships and obligations (think of it as Google for your contracts). Bonus: it comes with out-of-the-box dashboards for things like renewal dates, so you can spot risks and opportunities at a glance. - Docusign Maestro link: A no-code workflow engine to automate agreement workflows from start to finish. Maestro lets you design customizable workflows that orchestrate Docusign tasks and integrate with third-party apps – all without writing code. For example, you could have a workflow for new vendor onboarding: once a vendor contract is signed, Maestro could automatically notify your procurement team, create a task in your project tracker, and update a record in your ERP system. At the conference, they demoed how Maestro can streamline processes like employee onboarding and compliance checks through simple drag-and-drop steps or archiving PDFs of signed agreements into Google Drive or Dropbox. - Docusign Iris (AI Engine) link: The brains of the operation. Iris is the new AI engine powering all of IAM’s “smarts” – from reading documents to extracting data and making recommendations. It’s behind features like automatic field extraction, AI-assisted contract review, intelligent search, and even document summarization. In the keynote, we saw examples of Iris in action: identify key terms (e.g. payment terms or renewal clauses) across a stack of contracts, or instantly generate a summary of a lengthy agreement. These capabilities aren’t just gimmicks; as one Docusign executive put it, they’re “signals of a new way of working with agreements”. Iris essentially gives your agreement workflow a brain – it can understand the content of agreements and help you act on it. - Docusign App Center link: A hub to connect the tools of your trade into Docusign. App Center is like an app store for integrations – it lets you plug in other software (project management, CRM, HR systems, etc.) directly into your Maestro workflows. This is huge for developers (and frankly, anyone tired of building one-off integrations). Instead of treating Docusign as an isolated e-signature tool, App Center makes it a platform you can extend. I’ll dive more into this in the next section, since it’s close to my heart – my team helped build some of these integrations! In short, IAM ties together the stages of an agreement (create → sign → store → manage) and supercharges each with automation and AI. It’s modular, too – you can adopt the pieces you need. Docusign essentially unbundled the agreement process into building blocks that developers and admins can mix-and-match. The future of agreements, as Docusign envisions it, is a world where organizations *“seamlessly add, subtract, and rearrange modular solutions to meet ever-changing needs”* on a single trusted platform. The App Center and Real-World Integrations (Yes, We Built Those!) One of the most exciting parts of Momentum 2025 for me was seeing the Docusign App Center come alive. As someone who works on integrations, I was practically grinning during the App Center demos. Docusign highlighted several partner-built apps that snap into IAM, and I’m proud to say This Dot Labs built six of them – including integrations for Monday.com, Slack, Jira, Asana, Airtable, and Mailchimp. Why are these integrations a big deal? Because developers often spend countless hours wiring up systems that need to talk to each other. With App Center, a lot of that heavy lifting is already done. You can install an app with a few clicks and configure data flows in minutes instead of coding for months. In fact, a study found it takes the average org 12 months to develop a custom workflow via APIs, whereas with Docusign’s platform you can do it via configuration almost immediately. That’s a game-changer for time-to-value. At our This Dot Labs booth, I spoke with many developers who were intrigued by these possibilities. For example, we showed how our Docusign Slack Extension lets teams send Slack messages and notifications when agreements are sent and signed.. If a sales contract gets signed, the Slack app can automatically post a notification in your channel and even attach the signed PDF – no more emailing attachments around. People loved seeing how easily Docusign and Slack now talk to each other using this extension. Another popular one was our Monday.com app. With it, as soon as an agreement is signed, you can trigger actions in Monday – like assigning onboarding tasks for a new client or employee. Essentially, signing the document kicks off the next steps automatically. These integrations showcase why IAM is not just about Docusign’s own features, but about an ecosystem. App Center already includes connectors for popular platforms like Salesforce, HubSpot, Workday, ServiceNow, and more. The apps we built for Monday, Slack, Jira, etc., extend that ecosystem. Each app means one less custom integration a developer has to build from scratch. And if an app you need doesn’t exist yet – well, that’s an opportunity. (Shameless plug: we’re happy to help build it!) The key takeaway here is that Docusign is positioning itself as a foundational layer in the enterprise software stack. Your agreement workflow can now natively include things like project management updates, CRM entries, notifications, and data syncs. As a developer, I find that pretty powerful. It’s a shift from thinking of Docusign as a single SaaS tool to thinking of it as a platform that glues processes together. Not Just Another Contract Tool – Why IAM Matters for Business After absorbing all the Momentum keynotes and sessions, one thing is clear: IAM is not “just another contract management tool.” It’s aiming to be the platform that automates critical business processes which happen to revolve around agreements. The use cases discussed were not theoretical – they were tangible scenarios every developer or IT lead will recognize: - Procurement Automation: We heard how companies are using IAM to streamline procurement. Imagine a purchase order process where a procurement request triggers an agreement that goes out for e-signature, and once signed, all relevant systems update instantly. One speaker described connecting Docusign with their ERP so that vendor contracts and purchase orders are generated and tracked automatically. This reduces the back-and-forth with legal and ensures nothing falls through the cracks. It’s easy to see the developer opportunity: instead of coding a complex procurement approval system from scratch, you can leverage Docusign’s workflow + integration hooks to handle it. Docusign IAM is designed to connect to systems like CRM, HR, and ERP so that agreements flow into the same stream of data. For developers, that means using pre-built connectors and APIs rather than reinventing them. - Faster Employee Onboarding: Onboarding a new hire or client typically involves a flurry of forms and tasks – offer letters or contracts to sign, NDAs, setup of accounts, etc. We saw how IAM can accelerate onboarding by combining e-signature with automated task generation. For instance, the moment a new hire signs their offer letter, Maestro could trigger an onboarding workflow: provisioning the employee in systems, scheduling orientation, and creating tasks in tools like Asana or Monday. All those steps get kicked off by the signed agreement. Docusign Maestro’s integration capabilities shine here – it can tie into HR systems or project management apps to carry the baton forward. The result is a smoother day-one experience for the new hire and less manual coordination for IT and HR. As developers, we can appreciate how this modular approach saves us from writing yet another “onboarding script”; we configure the workflow, and IAM handles the rest. - Reducing Contract Auto-Renewal Risk: If your company manages a lot of recurring contracts (think vendor services, subscriptions, leases), missing a renewal deadline can be costly. One real-world story shared at Momentum was about using IAM to prevent unwanted auto-renewals. With traditional tracking (spreadsheets or calendar reminders), it’s easy to forget a termination notice and end up locked into a contract for another year. Docusign’s solution: let the AI engine (Iris) handle it. It can scan your repository, surface any renewal or termination dates, and proactively remind stakeholders – or even kick off a non-renewal workflow if desired. As the Bringing Intelligence to Obligation Management session highlighted, “Missed renewal windows lead to unwanted auto-renewals or lost revenue… A forgotten termination deadline locks a company into an unneeded service for another costly term.” With IAM, those pitfalls are avoidable. The system can automatically flag and assign tasks well before a deadline hits. For developers, this means we can deliver risk-reduction features without building a custom date-tracking system – the platform’s AI and notification framework has us covered. These examples all connect to a bigger point: agreements are often the linchpin of larger business processes (buying something, hiring someone, renewing a service). By making agreements “intelligent,” Docusign IAM is essentially automating chunks of those processes. This translates to real outcomes – faster cycle times, fewer errors, and less risk. From a technical perspective, it means we developers have a powerful ally: we can offload a lot of workflow logic to the IAM platform. Why code it from scratch if a combination of Docusign + a few integration apps can do it? Why Developers Should Care about IAM (Big Time) If you’re a software developer or architect building solutions for business teams, you might be thinking: This sounds cool, but is it relevant to me? Let me put it this way – after Momentum 2025, I’m convinced that ignoring IAM would be a mistake for anyone in enterprise software. Here’s why: - Faster time-to-value for your clients or stakeholders: Business teams are always pressuring IT to deliver solutions faster. With IAM, you have ready-made components to accelerate projects. Need to implement a contract approval workflow? Use Maestro, not months of coding. Need to integrate Docusign with an internal system? Check App Center for an app or use their APIs with far less glue code. Docusign’s own research shows that connecting systems via App Center and Maestro can cut development time dramatically (from ~12 months of custom dev to mere weeks or less). For us developers, that means we can deliver results sooner, which definitely wins points with the business. - Fewer custom builds (and less maintenance): Let’s face it – maintaining custom scripts or one-off integrations is not fun. Every time a SaaS API changes or a new requirement comes in, you’re back in the code. IAM’s approach offers more reuse and configuration instead of raw code. The platform is doing the hard work of staying updated (for example, when Slack or Salesforce change something in their API, Docusign’s connector app will handle it). By leveraging these pre-built connectors and templates, you write less custom code, which means fewer bugs and lower maintenance overhead. You can focus your coding effort on the unique parts of your product, not the boilerplate integration logic. - Reusable and modular workflows: I love designing systems as Lego blocks – and IAM encourages that. You can build a workflow once and reuse it across multiple projects or clients with slight tweaks. For instance, an approval workflow for sales contracts might be 90% similar to one for procurement contracts – with IAM, you can reuse that blueprint. The fact that everything is on one platform also means these workflows can talk to each other or be combined. This modularity is a developer’s dream because it leads to cleaner architecture. Docusign explicitly touts this modular approach, noting that organizations can easily rearrange solutions on the fly to meet new needs. It’s like having a library of proven patterns to draw from. - AI enhancements with minimal effort: Adding AI into your apps can be daunting if you have to build or train models yourself. IAM essentially gives you AI-as-a-service for agreements. Need to extract key data from 1,000 contracts? Iris can do that out-of-the-box. Want to implement a risk scoring for contracts? The AI can flag unusual terms or deviations. As a developer, being able to call an API or trigger a function that returns “these are the 5 clauses to look at” is incredibly powerful – you’re injecting intelligence without needing a data science team. It means you can offer more value in your applications (and impress those end-users!) by simply tapping into IAM’s AI features. Ultimately, Docusign IAM empowers developers to build more with less code. It’s about higher-level building blocks. This doesn’t replace our jobs – it makes our jobs more focused on the interesting problems. I’d rather spend time designing a great user experience or tackling a complex business rule than coding yet another Docusign-to-Slack integration. IAM is taking care of the plumbing and adding a layer of smarts on top. Don’t Underestimate Agreement Intelligence – Your Call to Action Momentum 2025 left me with a clear call to action: embrace agreement intelligence. If you’re a developer or tech leader, it’s time to explore what Docusign IAM can do for your projects. This isn’t just hype from a conference – it’s a real shift in how we can deliver solutions. Here are a few ways to get started: - Browse the IAM App Center – Take a look at the growing list of apps in the Docusign App Center. You might find that integration you’ve been meaning to build is already available (or one very close to it). Installing an app is trivial, and you can configure it to fit your workflow. This is the low-hanging fruit to immediately add value to your existing Docusign processes. If you have Docusign eSignature or CLM in your stack, App Center is where you extend it. - Think about integrations that could unlock value – Consider the systems in your organization that aren’t talking to each other. Is there a manual step where someone re-enters data from a contract into another system? Maybe an approval that’s done via email and could be automated? Those are prime candidates for an IAM solution. For example, if Legal and Sales use different tools, an integration through IAM can bridge them, ensuring no agreement data falls through the cracks. Map out your agreement process end-to-end and identify gaps – chances are, IAM has a feature to fill them. - Experiment with Maestro and the API – If you’re technical, spin up a trial of Docusign IAM. Try creating a Maestro workflow for a simple use case, or use the Docusign API/SDKs to trigger some AI analysis on a document. Seeing it in action will spark ideas. I was amazed how quickly I could set up a workflow with conditions and parallel steps – things that would take significant coding time if I did them manually. The barrier to entry for adding complex logic has gotten a lot lower. - Stay informed and involved – Docusign’s developer community and IAM documentation are growing. Momentum may be over, but the “agreement intelligence” movement is just getting started. Keep an eye on upcoming features (they hinted at even more AI-assisted tools coming soon). Engage with the community forums or join Docusign’s IAM webinars. And if you’re building something cool with IAM, consider sharing your story – the community benefits from hearing real use cases. My final thought: don’t underestimate the impact that agreement intelligence can have in modern workflows. We spend so much effort optimizing various parts of our business, yet often overlook the humble agreement – the contracts, forms, and documents that initiate or seal every deal. Docusign IAM is shining a spotlight on these and saying, “Here is untapped gold. Let’s mine it.” As developers, we have an opportunity (and now the tools) to lead that charge. I’m incredibly excited about this new chapter. After seeing what Docusign has built, I’m convinced that intelligent agreements can be a foundational layer for digital transformation. It’s not just about getting documents signed faster; it’s about connecting dots and automating workflows in ways we couldn’t before. As I reflect on Momentum 2025, I’m inspired and already coding with new ideas in mind. I encourage you to do the same – check out IAM, play with the App Center, and imagine what you could build when your agreements start working intelligently for you. The future of agreements is here, and it’s time for us developers to take full advantage of it. Ready to explore? Head to the Docusign App Center and IAM documentation and see how you can turn your agreements into engines of growth. Trust me – the next time you attend Momentum, you might just have your own success story to share. Happy building!...
