In 5-10 years, where do you think web application development and meta frameworks are heading with the current trend of experimentation?

The discussion got off to a quick start, and there seemed to be a consensus that the web development ecosystem is currently going through a phase of experimentation, with numerous frameworks and tools popping up and evolving rapidly. This creative and innovative environment allows developers to explore various solutions, leading to a wide array of choices.

Looking ahead, it's difficult to predict the exact form of an ideal development environment in 5-10 years. However, there is an expectation that the web development community will eventually converge on some consensus regarding best practices and tools. Some current practices, like hydration (the process of converting server-rendered HTML into a fully interactive application on the client-side), might be considered wasteful in an idealized future and could be replaced with more efficient approaches.

One significant consideration for the future of web development is competition between web applications and mobile apps. While the web has advantages in terms of faster initial loading and no need to download large app files, mobile apps are often perceived as having better user experiences. Closing the gap between web and app experiences will likely be a focus in the coming years.

The ease of creating meta frameworks is seen as a positive aspect of the current ecosystem. The availability of bundlers and underlying tooling has made it possible for developers to build their frameworks on top of existing libraries and tools. This ease of creation has led to an explosion of ideas and innovation in the space.

However, the growing complexity and the abundance of choices can also be overwhelming for newcomers to web development. The abundance of frameworks and tools may make it challenging for beginners to know where to start. Simplifying the development process and making the technology more approachable for new developers will likely be a concern for the future.

There's also a cautious perspective regarding abstracting complexity too much. While meta frameworks and high-level abstractions can make development easier and faster, there's a risk of losing touch with the underlying technology and ending up with monolithic solutions that become difficult to maintain and replace.

In summary, the web development landscape is currently characterized by experimentation and rapid evolution. As the community continues to explore and innovate, it is expected that the industry will eventually converge on more standardized practices and tools. Finding the right balance between abstraction and maintainability will be crucial for the future of web application development.

Will other tech stacks follow Next.js in adopting server-first approaches with React's server components?

The discussion revolves around Next.js adopting React's server components, which indicates a shift towards server-first approaches in their development. The conversation contemplates the potential impact of this trend and whether it might lead to similar shifts in other tech stacks.

React's server components are viewed as a new and hot trend in the React ecosystem, with no similar implementations currently in other tech stacks. The participants discuss how web development has evolved over the past years, from server-rendered PHP and Rails applications to the rise of JavaScript and single-page applications (SPAs), and now the current move back towards server rendering and server component rendering.

Opinions differ on the real benefits of server components compared to more established server-side rendering approaches. Some participants express support for server components, appreciating the server-first philosophy and the idea of shipping HTML from the server to the client. Others question the advantages of introducing server components when client-side models are already highly capable and suitable for building dynamic apps.

The conversation touches on the challenges of adopting new approaches and integrating them with existing ecosystems. Legacy concerns and the need for education within the React community are mentioned as potential obstacles to widespread adoption.

However, it's acknowledged that some frameworks have already taken the path of starting with server rendering and then adding client-side functionality later. The debate continues, with participants emphasizing the ongoing innovation and experimentation in reducing JavaScript costs and execution in the browser.

Despite the differing approaches taken by underlying libraries and frameworks, there seems to be a degree of consolidation and agreement among metaframeworks in terms of handling progressive enhancement, server functions, file-based routing, and other patterns.

React server components are considered a special addition to the Redwood framework, which already incorporates a back-end component, mainly focused on GraphQL. The advantages of back-end flexibility and server-side rendering, particularly for tasks like handling Open Graph meta tags, are highlighted.

In conclusion, the participants express various viewpoints on the adoption of server components and server-first approaches. While there are differing opinions on their benefits and practicality, the conversation suggests that innovation and experimentation in web development will continue to shape the direction of tech stacks in the future.

What advice would you give to developers just starting to learn a new meta framework, and what are the learning curves typically associated with them?

For developers starting to learn a new meta framework, the panel suggests considering the purpose of their project and what they want to achieve. For simple projects like personal blogs or static sites, options like WordPress or templating with Astro may be more straightforward. However, for dynamic applications or job prospects, learning a popular component framework like React is recommended due to its extensive documentation and community support.

The importance of having a strong foundation in JavaScript, HTML, and CSS is emphasized before delving into meta frameworks. For beginners, learning the fundamentals is key, and then they can progress to using a meta framework that aligns with their interests and goals.

The panel acknowledges that the choice of framework might not be as crucial as many believe. The important thing is to pick one that feels comfortable and appealing, as the skills and patterns acquired will be transferable to other frameworks if needed.

Job market prospects can be enhanced by being well-versed in cutting-edge frameworks, as companies using less common technologies may highly value developers with expertise in those areas.

Ultimately, the advice is to avoid getting paralyzed by the fear of making the "wrong" choice and to focus on finding a framework that resonates with personal preferences and aligns with project requirements. Being adaptable and willing to learn new technologies will make a developer stand out in the job market and as a valuable consultant.

What are each of you using for deployments and what is blocking other platforms?

When it comes to deployments in different ecosystems, the panelists shared their experiences and challenges. They discussed the adoption of adapters to simplify deployment processes across various platforms. Some mentioned using AWS S3, Netlify, and Parcel for static sites, while others emphasized the importance of considering the platform's limitations and performance.

The conversation touched on serverless functions and edge deployments, with mixed experiences across different frameworks. While some found serverless functions efficient and fast, others encountered configuration challenges and a lack of clear documentation. Overall, the panelists highlighted the ongoing experimentation and search for optimal deployment solutions, with open-source collaborations being key to driving progress in this space.

What are some common misconceptions or misunderstandings about your respective frameworks?

The panelists addressed common misconceptions and misunderstandings about their respective frameworks. Redwood was mistaken as a new framework, but in reality, it has been stable and established for over four years. They emphasized their focus on startups and core infrastructure, partnering with incubators to support end-users in that market.

Astro clarified that it is not limited to static sites and can handle dynamic single-client rendered apps with its flexibility in mounting components. SolidJS emphasized its goal of raising the baseline of primitives in the ecosystem, encouraging the use of existing libraries and promoting a future without lock-in frameworks. Crown showcased its selling point of partial hydration for optimal performance but acknowledged the challenge of explaining the concept to potential customers. Lastly, Nuxt was differentiated from Next, and it was clarified that Nuxt is optimized for performance, aims to simplify developer experience, and is not just the "next" version of Vue.

The panelists agreed that maintaining a meta framework is not easy and often involves complex version upgrading and bug fixes. Overall, the conversation shed light on the unique strengths and goals of each framework, debunking common misconceptions and providing insights into their usage and focus areas.

What's causing the shift away from first-class testing in libraries and frameworks, and will we see a return to testing-first tooling?

In this candid conversation, the panelists discussed the changing landscape of testing in libraries and frameworks. They acknowledged that many new releases are moving away from first-class testing in favor of end-to-end testing tools like Cypress and Playwright. Some frameworks, like Redwood, continue to support unit testing with Jest and JavaScript testing library, while others, like Svelte Kit, are shipping with Playwright out of the box. The shift seems to be driven by the complexity of modern applications, where bugs often emerge in the integration of various components and data sources.

The panelists emphasized that testing needs to address the actual complexity of the application, and in some cases, end-to-end testing proves more effective in detecting bugs and ensuring the overall system works as intended. However, they also acknowledged that there are still benefits to unit testing and emphasized the importance of having both types of testing in a robust application.

The challenge lies in finding the right balance and tooling to suit different types of frameworks and projects. The diversity of opinions and preferences within the community makes it difficult to prescribe a one-size-fits-all approach to testing. Some frameworks prioritize ease of use and simplicity for beginners, while others lean towards comprehensive end-to-end testing for complex applications.

Overall, the future of testing-first tooling remains uncertain. While there may be a shift back towards unit testing in some cases, it seems that the focus will be on finding the right combination of testing approaches that best suit the specific needs and complexities of individual frameworks and applications.

Q&A

What are the panelists thoughts on Docusaurus?

The panelists discussed their thoughts on documentation tools, particularly Docusaurus. Some mentioned using their own custom solutions or other frameworks like Vpress and VuePress in the Vue ecosystem. Astro introduced their own documentation starter called Starlight, which aims to bring Docusaurus-like features to static templating languages open to any framework.

The panel also mentioned Next.js and how the React 18 documentation process used custom React components rather than Docusaurus. The focus on partial hydration was highlighted as a key factor that can make documentation sites even better.

Overall, the discussion reflected a diverse range of approaches and preferences when it comes to maintaining documentation for projects.

Is transpiling a necessary technique anymore, and what are the panelists’ thoughts on infrastructure as code?

The panelists had an interesting discussion about transpiling and infrastructure as code. Regarding transpiling, there was a consensus that while modernizing code to ESM (ECMAScript modules) is becoming more accessible, transpiling will still be necessary for a variety of reasons, including ensuring optimal performance and compatibility with different environments. The panel acknowledged that build tools and compilers are still widely used and will likely remain integral to the development process.

On the topic of infrastructure as code, the conversation centered around how frameworks are starting to offer more opinionated solutions for deploying applications seamlessly. Next.js, for example, automatically infers whether a page should be deployed as serverless or static based on code patterns and fetch calls. However, there were also concerns about the potential challenges and risks of overly automatic decisions when it comes to deploying and managing infrastructure. Astra's approach of explicit configuration and allowing developers to set defaults for routes was noted as a more conservative and safer option.

The discussion highlighted the ongoing evolution of these practices and how different frameworks are approaching the challenges of modern web development, providing varying degrees of automation and flexibility for developers. The general consensus was that while transpiling and infrastructure as code practices are continuously improving, they will still be essential components of web development for the foreseeable future.

Can you discuss a challenging problem you encountered while developing your meta framework and how you solved it?

During the discussion, the panelists shared challenging problems they encountered while developing their respective meta frameworks and how they approached solving them. One major challenge for Redwood was integrating GraphQL into their framework. While GraphQL can be powerful, not everyone is comfortable using it. Redwood aimed to simplify the process by providing conventions and handling complexities, making it easier for developers to work with GraphQL. This allowed applications to scale better, addressing over-fetching and waterfall issues.

In the Crown framework, caching was a primary focus due to the heavy reliance on third-party data sources that were not always fast enough. To tackle this, they implemented various caching mechanisms, including in-memory caches, persistent caches (e.g., Redis), and HTTP caching. They utilized decorators to specify which data should be cached and employed patterns like "reusing stale while revalidating" to ensure fresh data while maintaining fast response times.

For another panelist, the most challenging aspects of their meta framework were related to adapters and runtime components. They faced difficulties in balancing a generic interface for deploying apps anywhere while leveraging specific features of different platforms. Integrating platform-specific features without making the framework feel too platform-dependent was a considerable challenge. They explored the potential of generalizing certain aspects, such as key-value stores, to address common needs across platforms.

The panelists emphasized that navigating the ever-evolving landscape of serverless and edge computing, and integrating the innovations from various platforms without compromising the core functionalities of their frameworks, required careful consideration and creative problem-solving. Overall, the discussion shed light on the complexities and ongoing efforts to build user-friendly and powerful meta frameworks in the dynamic world of web development.

What are some of the most innovative or unexpected ways you’ve seen your frameworks being used?

During the lively discussion, the panelists shared some unexpected and innovative ways their frameworks have been used in real-world scenarios.

For instance, with Astro, they were pleasantly surprised to see Bloomberg experimenting with using it to template news articles. It was used alongside their existing framework in A/B tests, demonstrating Astro's versatility and ease of integration with other platforms. Additionally, Astro's middleware mode was another exciting discovery, allowing it to be deployed as a node server middleware, making it even more adaptable for existing projects.

Redwood, on the other hand, was amazed by the diverse range of use cases their framework supported, from consumer applications to deep vertical SaaS implementations. The community's adoption of Redwood for various purposes showcased its flexibility and robustness.

In the case of SolidJS, the team was surprised to find developers using Solid as the foundation for mobile apps and Electron applications. Solid's client-only mode was adapted for these use cases, demonstrating its potential to support mobile development and native-like experiences.

A particularly jaw-dropping example came from the Svelte community, where developers managed to recreate the classic game Wolfenstein 3D in the browser using just DOM elements and CSS 3D transforms. This creative use of Svelte showcased its DOM manipulation capabilities and the powerful potential of modern browsers.

Overall, the panelists were impressed by the ingenious ways developers harnessed the capabilities of their frameworks to solve unique challenges and create unconventional applications.

Conclusion

The overall discussion provided a glimpse into the dynamic and exciting world of meta frameworks and the ever-evolving possibilities they bring to web development. With such remarkable use cases and continuous innovation, the future of meta frameworks looks promising. The panelists expressed their gratitude to the audience for joining and participating in the event, and they all looked forward to meeting again in future events.

Improving INP in React and Next.js

Improving INP in React and Next.js In one of my previous articles, I've explained what INP is, how it works, and how it may affect your website. I also promised you to follow up with more concrete advice on how to improve your INP in your favorite framework. This is the follow-up article, where I'll focus on how to improve your INP score in React and Next.js. How to prepare for INP in React and Next.js? The first thing to do is to ensure you're using the latest version of React. The React team has been working on making React more INP-friendly and has already made some improvements in the latest versions. To enhance your INP score, consider fully taking advantage of new features introduced in React 18, such as Concurrent Rendering, Automatic Batching, and Selective Hydration. However, there are also some general areas to focus on, such as SSR and SSG in Next.js, Web Workers, or optimizing your hooks and state management. Concurrent Rendering The Concurrent Mode in React uses an algorithm that breaks rendering down into so-called "fiber nodes" and schedules the renders based on their expiration and priority. This effectively allows the user to interact with the page while the rendering is still in progress. In previous React versions, all updates, such as setState calls were treated as "urgent" and once the re-render had started, there was no way to interrupt it. Concurrent Mode changes this by being able to prioritize the updates and interrupt a non-blocking state update started with startTransition. For a simple explanation of concurrency in React, you can check out Dan Abramov's explanation. As part of the Concurrent Mode, React introduced several lifecycle methods that allow you to prioritize the rendering of certain parts of your UI, such as: - useTransition hook that allows you to update the state without blocking the UI, - useDeferredValue hook that allows you to defer the rendering of certain parts of your UI, - startTransition API that, similarly to the useTransition hook lets you mark a state update as non-blocking. It lacks, however, an indication of whether it's still pending. Automatic Batching Introduced in React 18, Automatic Batching reduces the number of re-renders that happen on state changes even when they happen outside of event handlers, e.g. in a setTimeout or Promise callback. This feature comes out of the box and you don't have to do anything to enable it, and it makes a great argument for upgrading to React 18. Selective Hydration Selective Hydration allows you to take hydration off the main thread by wrapping your components in a Suspense boundary. This way, components can become interactive faster as the browser can do other work on the main thread while the hydration is happening. To fully take advantage of selective hydration, consider the following: - Prioritizing Above-the-Fold Content: Use Suspense boundaries strategically around any parts of your application that may take the server longer to deliver to ensure they don’t block critical content from becoming interactive as soon as possible. - Hydration on Interaction: Implementing hydration upon user interaction for non-critical components can drastically reduce the main thread's workload, enhancing INP. Vercel even has a small case study showing how using selective hydration improved the performance of a Next.js site. Server-Side Rendering (SSR) and Static Site Generation (SSG) in Next.js Not everything has to run client-side. Next.js excels in SSR and SSG capabilities, which can significantly impact INP by delivering content to users faster. Optimizing SSR with techniques like incremental static regeneration (ISR) or leveraging SSG for static pages ensures that users can interact with content faster, improving the perceived performance. Workers Offloading heavy computations to Web Workers can free up the main thread, enhancing the responsiveness of React and Next.js applications. This strategy is especially useful when dealing with third-party scripts. Offloading such scripts in Next.js can be easily done by specifying the "worker" strategy on your Script component. Be aware that this feature is not yet stable and does not work with the app directory, though. If you want to take things one step further, you could use Partytown, which helps you offload any resource-intensive scripts to Web Workers. It comes with a React component that you can use to wrap your third-party scripts and offload them to a Web Worker, and it's compatible with Next.js as well. Hooks and State Management State management in React applications can easily get out of hand, leading to unnecessary re-renders and effectively an increased INP. Sometimes, using a state management library like Redux or MobX can help you consolidate your state and reduce the number of re-renders. However, they are not silver bullets and can also introduce performance issues if not used properly. If you are dealing with a lot of re-renders due to prop changes, make sure you are leveraging memoization. As of now, you may need to work with useMemo and useCallback hooks to memoize your values and functions, respectively. The upcoming React 19’s Forget Compiler, however, will apparently memoize everything under the hood, making these hooks obsolete. Using memoization properly can help you reduce the number of re-renders and improve your INP. To investigate your hook dependencies and re-renders, you can leverage React Developer Tools or use this handy helper hook I found on the internet to trace your re-renders: ` Conclusion Improving INP in React and Next.js is not easy and can require much investigation and fine-tuning. Still, it's worth doing to avoid being penalized by Google in its search results and provide a better experience for your users. Adopting React 18's new features, leveraging SSR and SSG in Next.js, utilizing Web Workers, and optimizing hooks and state management can significantly boost your INP score and deliver a faster application to your users. Remember, INP is just one among many performance metrics emphasizing the need for a comprehensive approach to performance optimization...

Intro to EdgeDB - The 10x ORM

Intro to EdgeDB - The 10x ORM I’ve written a couple of posts recently covering different TypeScript ORMs. One about Prisma, and another about Drizzle. ORM’s are a controversial topic in their own right - some people think they are evil, and others think they are great. I enjoy them quite a bit. They make it easy to interact with your databases. What is more important and magical for an application than data? SQL without an ORM is amazing as well, but there are some pain points with that approach. Today I’m excited to write about EdgeDB, which isn’t _exactly_ an ORM or a database from my perspective (although they call themselves one). It is, however an incredibly impressive piece of technology that solves these common pain points in a pretty novel way. So if it’s not an ORM or a database, what exactly is it? I don’t think I can answer that in one or two sentences, so we will explore the various pieces that make up EdgeDB in this article. From a high-level standpoint, though, an interface/query language that sits in front of PostgreSQL. This may seem like some less important implementation detail, but in my eyes, it’s a feature and one of the most compelling selling points. Data Modeling EdgeDB advertises itself as a “graph-relational database”. The core components of EdgeDB data modeling are the schema, type system, and relationship definitions. A schema will consist of objects that contain various typed attributes and links that connect the objects. In SQL, a table is analogous to an Object, and a foreign-key is associated with a link. Here’s what a simple schema in EdgeDB looks like ` There’s a few things to highlight here * We defined two different objects (tables) User and Post * Each object contains properties with their types defined * str is one of several scalar types (bool, int, float, json, datetime, etc) * the author property is a required link to the User object Defining relations / associations In our example above we defined a one-to-many relationship between a user and posts. All the relation types that you can define in traditional SQL are available. One interesting feature though is called backward links. These can be defined in your schema and it allows you to access related data from both sides of a relationship. ` likes are a many-to-many relationship between Tweet and User. With a backlink defined multi link likers := Tweet.<likes[is User]; - we can access likes from a User and likers from a Tweet. ` That's how we can access these relations in our queries. You might be looking at these queries and thinking it looks a lot like GraphQL. This is why they call it a ‘Graph-relational’ database. We’ve only scratched the surface of EdgeDB schema’s. Hopefully, I’ve at least managed to pique your interest. Computed properties Computed properties are a super powerful feature that can be added to your schema or queries. This example user schema creates a computed discriminator and username property. The discriminator uses an EdgeDB standard library function to generate a discriminator number and the username property is a combination between the name and discriminator properties. ` Globals and Access Policies EdgeDB allows you to define global variables as part of your schema. The most common use case I’ve seen for this is to power the access policy feature. You can define a global variable as part of your schema: global current_user: uuid; With a global variable defined, you can provide the value as a sort of context from your application by providing it into your EdgeDB driver/client. ` You can then add access policies directly to your schema, for example, to provide fine-grained access control to blog posts in your blogging application. ` Aside from access policies, you can use your global variables in your queries as well. For example, if you wanted a query to select the current user. ` Types and Sets EdgeDB is very type-centric. All of your data is strongly typed. We’ve touched on some of the types already. * Scalars - There are a lot of scalar types available out of the box * Custom scalars - Custom scalar types are user-defined extensions of existing types * Enums - Are supported out of the box - enum<Admin, Moderator, Member> * Arrays - Defined by passing the singular value type - array<str>; * Tuples - In EdgeD, tuples can contain more than 2 elements and come in named and unnamed varieties - <str, number>; tuple<name: str, jersey_number: float64, active: bool>; All queries return a Set which is a collection of values of a given type. In the query language, all values are Sets. Sets are a collection of values of a given type. A comma-separated list of values inside a set of {curly braces}. A query with no results will return an empty or singleton set. If we have no User values stored yet - select User returns {}. Paired with the query language types and set provides an incredibly powerful and expressive system for interacting with your data. If you thought TypeScript was cool, wait until you start writing EdgeQL! 🙂 EdgeQL Now to the fun stuff: the query language. We’ll use a schema from the docs and start by looking at some of those queries and build on those. The example schema has an abstract type Person with two sub-types based on it Hero and Villian. This is known as a polymorphic type in EdgeDB. The Movie type includes a 1:m association with Person ` Selecting properties / data Before we dig into some real queries we should just touch on how we select actual data from a query. It’s pretty obvious and GraphQL-like but worth mentioning. To specify properties to select, you attach a shape. This works for getting nested link / association data as well. Based on our schema, here’s how we could select fields from Movie, including data from the collection of related characters. ` There is also a feature called a splats that allows you to select all fields and/or all linked fields without specifying them individually. ` If you don’t specify any properties or splats, only id’s get returned select Movie; . Adding some objects with insert To get started, we can use insert to add objects to our database. We’ll start big by looking at the nested insert example. This example is interesting because it shows the creation of two objects in a single query. You’ll notice the simplicity of the syntax. Even though this is the first EdgeQL query we’re looking at, in my experience, it’s like this across the board. I’ve found EdgeQL queries to be simple and intuitive to the point where I’ve been able to intuit how to accomplish things in my head without having to reference the docs or ask the AI. This example adds a new Villian and a new Hero which gets assigned as a link or association to the nemesis field on our Villian. To accomplish this we see that we can nest queries by wrapping them in (). ` The next example is pretty similar, but instead of creating the linked property, we are select ing and adding several potential objects to the characters list of Movie since it is a multi link. This is a pretty complex query that is doing a lot of different things. It’s deceivingly succinct. To accomplish the same thing with SQL this would probably be about 3 different queries. This query finds the objects to add to the characters multi link by filtering on a collection of different strings to match against the name property. ` The last thing we’ll cover for insert is bulk inserts. This is particularly useful for things like seed scripts. In this example, you can just imagine that you have a JSON array of objects with hero names that gets passed in as an argument to your query ` Querying data with select We’ve already seen subqueries and a select in the last section where we found a collection of Person records with a filter. We’ll build on that and see what tools are available to us when it comes to querying data. This one covers a lot of ground. Very similar to SQL we have order and limit, and offset operators to support sorting and pagination. Also there is a whole standard library of functions and operators like count that can be used in our queries. This example returns a collection of villian names, excluding the first and last result. ` Most commonly, you will want to filter by an id ` Here’s another common example filtering by datetime. Since we’re using a string value here we need to cast it to the EdgeDB datetime type. ` You get a pretty similar toolbox to SQL when it comes to filtering with your common operators and things. Combined with all the tools in the standard library, you can get pretty creative with it. Changing values and links with update The update..filter..set statement is how we can update existing data with EdgeQL. set is followed by a shape with assignments of properties to be updated. ` You can replace links for an object ` or add additional ones ` An even more interesting example is removing links matched on a type. Since Villian is a sub-type of Person , this query will remove all characters linked of the Villian type. ` Deleting objects with delete Deleting is pretty straight forward. Using the delete command you can just filter for the objects that you would like to remove. ` When the EdgeQL pieces fall into place As you become more familiar with the EdgeQL query language chances are you’ll start writing very complex queries fluently because everything just makes sense once you’ve learned the building blocks. Domain and business concerns I don’t think they explicitly mention this as a goal anywhere but it’s something that I picked up on pretty quickly. EdgeDB nudges you to move more of what might have traditionally been application logic into your database layer. This is a topic that can bring a lot of division since even things like foreign keys and constraints in SQL are frowned upon in some circles. EdgeDB goes as far as providing constraints, global variables, contexts, and authorization support built into the database. I think that the ability to bake some of these concerns into your EdgeDB Schema is great. The way you model your schema and database in EdgeDB map to your domain in a much more intuitive way where domain concerns don’t really feel out of place there. Database Clients and Query Builders and Generators We’ve covered a lot so far to highlight what EdgeDB is and how to handle common use cases with the query language. To use it in your project though, you will need a client/driver library. There are clients available in several different languages. The one that they clearly have put the most investment into is the TypeScript query builder. We’ll briefly look at both options: simple driver/client and query builder. Whichever you end up choosing you will need to instantiate a driver and make sure you have a connection to your database instance configured. Basic client Although the TS query builder is very popular and pretty amazing, I couldn’t get away from just writing EdgeQL queries. In my application, I composed queries using template strings, and it worked great. The clients all have a set of methods available for passing in EdgeQL queries and parameters. querySingle is a method for queries where you are only expecting a single result. If your query will have multiple results you would use query instead. There is also a queryRequiredSingle which will throw an error if no results are found. There are some other methods available as well including one for running queries in a transaction ` The first argument is the query, and the second is a map of parameters. In this example we include the title parameter and it is accessed in our query via $title. TypeScript query builder If you have a TypeScript app and type-safety is important, you might prefer using the query builder. It is a pretty incredible feat of TypeScript magic initially developed by the same developer behind the popular library Zod. We can’t cover it in very much depth here but we’ll look at an example just to have an idea of what the query builder looks like in an application. ` The query builder is able to infer the result type automatically. It knows which fields you’ve selected, it knows that the result will be a single item. Query generator There are generators for queries and types. So even if you opt out of using the query builder you can still have queries that are strongly typed. It’s nice to have this option if you want to just write your queries as EdgeQL in .edgeql files. ` We end up with an exported function named getUser that is strongly typed. ` Tools and Utilities The team at EdgeDB puts a big emphasis on developer experience. It shows up all over the place. We’ve already seen some utilities with the generators that are available. There are some other tools available as well that help complete the entire experience. EdgeDB CLI The first and most important tool to mention is the CLI. If you’ve started using EdgeDB then you’ve most likely already installed and used it. The CLI is pretty extensive. It includes commands for things like migrations, managing EdgeDB versions and installations, managing projects and local/cloud database instances, dumps and restores, a repl, and more. The CLI makes managing EdgeDB a breeze. Admin UI The CLI includes a command to launch an admin UI for any project or database. The Admin UI includes a awesome interactive diagram of your database schema, a repl for running queries, and a table to inspect and make changes to the data stored in your database. Summary Adopting newer database technology is a tough sales pitch. Replacing your application’s database technology at any point in its lifecycle is not a problem that anyone wants to have. This is one of the reasons why EdgeDB being a superset of PostgreSQL is a huge feature in my opinion. The underlying database technology is tried and true, and EdgeDB is open-source. Based on this, I would feel confident using EdgeDB if it aligned well from a technical and business perspective. We’ve covered a lot of ground in this post. EdgeDB is feature-packed and powerful. Databases is a tough nut to crack, and I commend the team for all their hard work to help continue pushing forward one of the most important components of almost any application. I’m typically pretty conservative when it comes to databases, but EdgeDB took a great approach, in my opinion. I recommend at least giving it a try. You might catch the EdgeDB bug like I did!...

State of Node.js Wrap-up

In this State of Node.js event, our panelists discussed updates, LTS releases and APIs with Node.js maintainers, technical steering committee members and collaborators, and much more. In this wrap-up, we will take a deeper look into these latest developments and explore what is on the horizon for Node.js. You can watch the full State of Node.js event on the This Dot Media YouTube Channel. Here is a complete list of the host and panelists that participated in this online event. Hosts: - Tracy Lee, CEO, This Dot Labs, @ladyleet - James Snell, Node.js Foundation Technical Steering Committee, @jasnell Panelists: - Beth Griggs, Senior Software Engineer, Red Hat, Node.js TSC Member, @BethGriggs_ - Matteo Collina, Co-Founder and CTO of Platformatic.dev, Node.js TSC member, @matteocollina - Michael Dawson, Node.js Lead, Red Hat and IBM, @mhdawson1 General state of Node.js Michael kicks off the conversation saying there are a lot of things happening with Node.js right now. There were over a billion downloads last year alone, and it is continuing to grow. Beth talked about the major release of Node v20 coming out in April. Node 14 end of life is coming at the end of April. Matteo talked about two micro conferences happening this year for Node.js. One will be in North America in Vancouver in May, and the other one is in September in Bilbao. Updates from specific working groups Michael talks about spinning up a uvwasi team. The wasi is the web assembly system interface. It’s not only used in Node, but in other projects like grain. It’s a key component of wasm support. Michael also talks about how the Node.js API team has been great for building long term contributors. If you’re interested in add-ons and native code, it is a friendly group to get involved with. Beth talks about other ways folks can contribute to Node.js. She talks about a redesign of the website that happened recently. The main website has been migrated over to Next.js. Matteo talks about a massive PR that is open right now about the new loader API. There is a lot of effort being put into this with a lot of contributors. This new loader will replace the - - hack. New Features Michael talks about the single executable application that enables bundling code into the Node.js binaries without having to build it. He also mentions process permissions. These are two big new experimental features right now. Beth talks about the built-in test runner. It allows you to throw some scripts together, and get some simple tests without having to deal with dependable warnings for a mod. End of Event Each panelist takes time to go over what they are currently doing on their own. Beth is working in security for releases, and takes time to talk about everything there. Michael is working with the Node API, which is a long-term working project. James is work on standard APIs and also bringing interoperability with Node, Bun, and Dino. Finally, Matteo is working on getting Platformatic going. Conclusion The conversation went in depth about the state of Node.js, and what is being done in the new releases as well as experimental updates. The panelists were very engaged, and were great at bringing up ways to get involved with the Node community. You can watch the full State of Node.js event on the This Dot Media Youtube Channel....
