Recently, there has been a lot of buzz on Angular’s SDK (a new version of the CLI), the never ending AngularJS to Angular upgrade question, Angular Material’s progress, and how to think of Angular’s directives in a way that may be more useful to your application development.

In these videos, we cover the latest Angular news with Hans Larsen (@hanslatwork)and Pete Bacon Darwin (@petebd) from the Angular Core Team, Elad Bezalel (@elad_bezalel) from the Angular Material Core team, Mike Brocchi (@Brocco)from the Angular-CLI Core Team, and Justin Searls (@searls), a JavaScript developer and speaker.

Angular CLI, SDK, and Angular 4.0

Hans Larsen Reveals Upcoming Angular Products and Discusses SDK

As a member of the core angular team, Hans has been working on SDK — the next version of CLI. He says his work involves helping developers with efficiency, by allowing them to manage their apps and projects, even before making an appearance to the browser. He’s also looking to make improvements to better the interface.

Hans further explains that individuals who are used to the current CLI, will be able to use the new version with ease. Default features will remain the same, and the upgrade path will be straightforward, made to support Angular 4.0. Having said that, SDK will be entirely redesigned from the ground up as a blueprint library. All very exciting news for the Angular community.

Angular, AngularJS, and Ng-upgrade

Pete Bacon Darwin, Angular Core Team on The Best Way to Upgrade Your AngularJS Applications

As a contributor who is still working on one of the biggest JavaScript frameworks, he talks about how to slow down the development of AngularJS in order to allow migration towards Angular. The parts of AngularJS that many people came to love still exist in Angular, which is more reason to help push developers towards Angular.

Easy upgrade can be accomplished with ngUpgrade, which allows angular and angularjs to run at the same time. This way, developers can continue to keep uptime for their clients while moving their code one part at a time. NgUpgrade is one of many potential solutions for the switch over to Angular.

Going back to when Angular was introduced, Pete talks about whether there was a better way to prepare the community for the migration. From his point of view, due to the existing architecture of Angularjs, there wasn’t anything that could’ve been done differently, as the Angular now is much more advanced in comparison.

The interview ends with Pete describing the Angular community and different frameworks coming together and converging ideas. He believes comparing and discussing ideas helps immensely with solutions as JavaScript and modern web in general continues to evolve.

Angular Material + Angular Material 2

Elad Bezalel, Angular Material Core Team: Being on The Angular Material Team

Elad Bezalel is a part of the Angular Material Team and is currently working on Material 2 components and features. He walks us through how he became a part of the team and what intrigued him the most about Material. Elad is very confident about this project and encourages developers to use it as an aid with their designing. He is still working on improvements and creating more components, but seeing as Material 2 is in its beta stage, it is ready for anyone who want to use it.

Angular Directives

Mike Brocchi and His Thoughts on Angular Directives

Mike describes becoming a member of the Angular-CLI Core team and contributing to the angular community to be more involved. In this interview, he talks about directives in detail, starting with the fact that they are underrated and should be promoted. He hopes in the future, people will be more aware of how to use directives effectively. He explains how it’s still a key part of Angular, even beyond Angularjs.

With directives, developers can add behaviours to their applications without having to separate components or add logic into their component.This could be done for many situations.

Mike also discusses when not to use a directive and expands a little on host binding and host listening. He then gives a breakdown of what else directives can accomplish, such as improving accessibility or being used to access templates from existing components. Mike also describes the differences between different types of directives.

Angular Community + Open Sourcing Projects

Overcoming the Challenges of being a Developer: Justin Searls Shares his Experience

Justin discusses what it’s like to learn Angular (coming from ember) and how frameworks have evolved, becoming more intense and “robust”. Although this is a good thing, he mentions it being important for there to be room for inventiveness, as this is why he chose to explore javascript in the first place. In his words “we need to make space for creativity and divergence instead of being on a unilateral path to solving applications”. This can easily be done with tools such as babel, which allows developers to experiment with different language features.

Justin elaborates on the non-technical side of being a developer. He talks about the feelings of frustration and upset, lack of motivation, and other barriers that come with being a developer. He then discusses how starting small, creative projects and open sourcing ideas can help channel these negative emotions, and turn them into something positive and applicable, as opposed to solely unbearable. He encourages developers to present their ideas even when they’re uncertain of the outcome, and gives tips on how to gain recognition in an effective and modest manner. All in all, Justin strives to provide a model for the industry, to normalize talking about weaknesses and shortcomings, no matter who you are, where you’re from, or what background you have as a developer.

Incremental Hydration in Angular

Incremental Hydration in Angular Some time ago, I wrote a post about SSR finally becoming a first-class citizen in Angular. It turns out that the Angular team really treats SSR as a priority, and they have been working tirelessly to make SSR even better. As the previous blog post mentioned, full-page hydration was launched in Angular 16 and made stable in Angular 17, providing a great way to improve your Core Web Vitals. Another feature aimed to help you improve your INP and other Core Web Vitals was introduced in Angular 17: deferrable views. Using the @defer blocks allows you to reduce the initial bundle size and defer the loading of heavy components based on certain triggers, such as the section entering the viewport. Then, in September 2024, the smart folks at Angular figured out that they could build upon those two features, allowing you to mark parts of your application to be server-rendered dehydrated and then hydrate them incrementally when needed - hence incremental hydration. I’m sure you know what hydration is. In short, the server sends fully formed HTML to the client, ensuring that the user sees meaningful content as quickly as possible and once JavaScript is loaded on the client side, the framework will reconcile the rendered DOM with component logic, event handlers, and state - effectively hydrating the server-rendered content. But what exactly does "dehydrated" mean, you might ask? Here's what will happen when you mark a part of your application to be incrementally hydrated: 1. Server-Side Rendering (SSR): The content marked for incremental hydration is rendered on the server. 2. Skipped During Client-Side Bootstrapping: The dehydrated content is not initially hydrated or bootstrapped on the client, reducing initial load time. 3. Dehydrated State: The code for the dehydrated components is excluded from the initial client-side bundle, optimizing performance. 4. Hydration Triggers: The application listens for specified hydration conditions (e.g., on interaction, on viewport), defined with a hydrate trigger in the @defer block. 5. On-Demand Hydration: Once the hydration conditions are met, Angular downloads the necessary code and hydrates the components, allowing them to become interactive without layout shifts. How to Use Incremental Hydration Thanks to Mark Thompson, who recently hosted a feature showcase on incremental hydration, we can show some code. The first step is to enable incremental hydration in your Angular application's appConfig using the provideClientHydration provider function: ` Then, you can mark the components you want to be incrementally hydrated using the @defer block with a hydrate trigger: ` And that's it! You now have a component that will be server-rendered dehydrated and hydrated incrementally when it becomes visible to the user. But what if you want to hydrate the component on interaction or some other trigger? Or maybe you don't want to hydrate the component at all? The same triggers already supported in @defer blocks are available for hydration: - idle: Hydrate once the browser reaches an idle state. - viewport: Hydrate once the component enters the viewport. - interaction: Hydrate once the user interacts with the component through click or keydown triggers. - hover: Hydrate once the user hovers over the component. - immediate: Hydrate immediately when the component is rendered. - timer: Hydrate after a specified time delay. - when: Hydrate when a provided conditional expression is met. And on top of that, there's a new trigger available for hydration: - never: When used, the component will remain static and not hydrated. The never trigger is handy when you want to exclude a component from hydration altogether, making it a completely static part of the page. Personally, I'm very excited about this feature and can't wait to try it out. How about you?...

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....

“We were seen as amplifiers, not collaborators,” Ashley Willis, Sr. Director of Developer Relations at GitHub, on How DevRel has Changed, Open Source, and Holding Space as a Leader

Ashley Willis has seen Developer Relations evolve from being on the sidelines of the tech team to having a seat at the strategy table. In her ten years in the space, she’s done more than give great conference talks or build community—she’s helped shape what the DevRel role looks like for software providers. Now as the Senior Director of Developer Relations at GitHub, Ashley is focused on building spaces where developers feel heard, seen, and supported. > “A decade ago, we were seen as amplifiers, not collaborators,” she says. “Now we’re influencing product roadmaps and shaping developer experience end to end.” DevRel Has Changed For Ashley, the biggest shift hasn’t been the work itself—but how it’s understood. > “The work is still outward-facing, but it’s backed by real strategic weight,” she explains. “We’re showing up in research calls and incident reviews, not just keynotes.” That shift matters, but it’s not the finish line. Ashley is still pushing for change when it comes to burnout, representation, and sustainable metrics that go beyond conference ROI. > “We’re no longer fighting to be taken seriously. That’s a win. But there’s more work to do.” Talking Less as a Leader When we asked what the best advice Ashley ever received, she shared an early lesson she received from a mentor: “Your presence should create safety, not pressure.” > “It reframed how I saw my role,” she says. “Not as the one with answers, but the one who holds the space.” Ashley knows what it’s like to be in rooms where it’s hard to speak up. She leads with that memory in mind, and by listening more than talking, normalizing breaks, and creating environments where others can lead too. > “Leadership is emotional labor. It’s not about being in control. It’s about making it safe for others to lead, too.” Scaling More Than Just Tech Having worked inside high-growth companies, Ashley knows firsthand: scaling tech is one thing. Scaling trust is another. > “Tech will break. Roadmaps will shift. But if there’s trust between product and engineering, between company and community—you can adapt.” And she’s learned not to fall for premature optimization. Scale what you have. Don’t over-design for problems you don’t have yet. Free Open Source Isn’t Free There’s one myth Ashley is eager to debunk: that open source is “free.” > “Open source isn’t free labor. It’s labor that’s freely given,” she says. “And it includes more than just code. There’s documentation, moderation, mentoring, emotional care. None of it is effortless.” Open source runs on human energy. And when we treat contributors like an infinite resource, we risk burning them out, and breaking the ecosystem we all rely on. > “We talk a lot about open source as the foundation of innovation. But we rarely talk about sustaining the people who maintain that foundation.” Burnout is Not Admirable Early in her career, Ashley wore burnout like a badge of honor. She doesn’t anymore. > “Burnout doesn’t prove commitment,” she says. “It just dulls your spark.” Now, she treats rest as productive. And she’s learned that clarity is kindness—especially when giving feedback. > “I thought being liked was the same as being kind. It’s not. Kindness is honesty with empathy.” The Most Underrated GitHub Feature? Ashley’s pick: personal instructions in GitHub Copilot. Most users don’t realize they can shape how Copilot writes, like its tone, assumptions, and context awareness. Her own instructions are specific: empathetic, plainspoken, technical without being condescending. For Ashley, that helps reduce cognitive load and makes the tool feel more human. > “Most people skip over this setting. But it’s one of the best ways to make Copilot more useful—and more humane.” Connect with Ashley Willis She has been building better systems for over a decade. Whether it’s shaping Copilot UX, creating safer teams, or speaking truth about the labor behind open source, she’s doing the quiet work that drives sustainable change. Follow Ashley on BlueSky to learn more about her work, her maker projects, and the small things that keep her grounded in a fast-moving industry. Sticker Illustration by Jacob Ashley....

Internationalization in Next.js with next-intl

Internationalization in Next.js with next-intl Internationalization (i18n) is essential for providing a multi-language experience for global applications. next-intl integrates well with Next.js’ App Router, handling i18n routing, locale detection, and dynamic configuration. This guide will walk you through setting up i18n in Next.js using next-intl for URL-based routing, user-specific settings, and domain-based locale routing. Getting Started First, create a Next.js app with the App Router and install next-intl: ` Next, configure next-intl in the next.config.ts file to provide a request-specific i18n configuration for Server Components: ` Without i18n Routing Setting up an app without i18n routing integration can be advantageous in scenarios where you want to provide a locale to next-intl based on user-specific settings or when your app supports only a single language. This approach offers the simplest way to begin using next-intl, as it requires no changes to your app’s structure, making it an ideal choice for straightforward implementations. ` Here’s a quick explanation of each file's role: * translations/: Stores different translations per language (e.g., en.json for English, es.json for Spanish). Organize this as needed, e.g., translations/en/common.json. * request.ts: Manages locale-based configuration scoped to each request. Setup request.ts for Request-Specific Configuration Since we will be using features from next-intl in Server Components, we need to add the following configuration in i18n/request.ts: ` Here, we define a static locale and use that to determine which translation file to import. The imported JSON data is stored in the message variable, and is returned together with the locale so that we can access them from various components in the application. Using Translation in RootLayout Inside RootLayout, we use getLocale() to retrieve the static locale and set the document language for SEO and pass translations to NextIntlClientProvider: ` Note that NextIntlClientProvider automatically inherits configuration from i18n/request.ts here, but messages must be explicitly passed. Now you can use translations and other functionality from next-intl in your components: ` In case of async components, you can use the awaitable getTranslations function instead: ` And with that, you have i18n configured and working on your application! \ Now, let’s take it a step further by introducing routing. \ With i18n Routing To set up i18n routing, we need a file structure that separates each language configuration and translation file. Below is the recommended structure: ` We updated the earlier structure to include some files that we require for routing: * routing.ts: Sets up locales, default language, and routing, shared between middleware and navigation. * middleware.ts: Handles URL rewrites and locale negotiation. * app/[locale]/: Creates dynamic routes for each locale like /en/about and /es/about. Define Routing Configuration in i18n/routing.ts The routing.ts file configures supported locales and the default locale, which is referenced by middleware.ts and other navigation functions: ` This configuration lets Next.js handle URL paths like /about, with locale management managed by next-intl. Update request.ts for Request-Specific Configuration We need to update the getRequestConfig function from the above implementation in i18n/request.ts. ` Here, request.ts ensures that each request loads the correct translation files based on the user’s locale or falls back to the default. Setup Middleware for Locale Matching The middleware.ts file matches the locale based on the request: ` Middleware handles locale matches and redirects to localized paths like /en or /es. Updating the RootLayout file Inside RootLayout, we use the locale from params (matched by middleware) instead of calling getLocale() ` The locale we get from the params was matched in the middleware.ts file and we use that here to set the document language for SEO purposes. Additionally, we used this file to pass configuration from i18n/request.ts to Client Components through NextIntlClientProvider. Note: When using the above setup with i18n routing, next-intl will currently opt into dynamic rendering when APIs like useTranslations are used in Server Components. next-intl provides a temporary API that can be used to enable static rendering. Static Rendering for i18n Routes For apps with dynamic routes, use generateStaticParams to pass all possible locale values, allowing Next.js to render at build time: ` next-intl provides an API setRequestLocale that can be used to distribute the locale that is received via params in layouts and pages for usage in all Server Components that are rendered as part of the request. You need to call this function in every layout/page that you intend to enable static rendering for since Next.js can render layouts and pages independently. ` Note: Call setRequestLocale before invoking useTranslations or getMessages or any next-intl functions. Domain Routing For domain-specific locale support, use the domains setting to map domains to locales, such as us.example.com/en or ca.example.com/fr. ` This setup allows you to serve localized content based on domains. Read more on domain routing here. Conclusion Setting up internationalization in Next.js with next-intl provides a modular way to handle URL-based routing, user-defined locales, and domain-specific configurations. Whether you need URL-based routing or a straightforward single-locale setup, next-intl adapts to fit diverse i18n needs. With these tools, your app will be ready to deliver a seamless multi-language experience to users worldwide....
