Release of TypeScript RC, new alternative to npm, future of JavaScript frameworks - This week in JS

Hello JavaScript enthusiasts!
Welcome to this week's edition of “This Week In JavaScript”

Today we dive into TypeScript's latest release contender, a thought-provoking discussion on the future of frameworks in the AI ​​era, and some must-have tools to boost your development game.

RC Terrains Typescript 5.7

You can now install TypeScript 5.7 Release Candidate with:
npm install -D typescript@rc

Here are the new features:

Smarter bug detection: New checks detect never-initialized variables, even in deeply nested functions.

No-build convenience: For ts-node and Deno users, the --rewriteRelativeImportExtensions option automatically converts .ts imports to .js, allowing developers to run TypeScript code from seamlessly across multiple environments like Node.js and Deno.

ECMAScript 2024: Full support for Object.groupBy and Promise.withResolvers, helping you take advantage of the latest ECMAScript features.

The Vlt Package Manager and Serverless Registry

Isaac Schlueter, the creator of npm, is back with something new: vlt and the serverless registry (vsr).

vlt Package Manager: a faster, more elegant alternative to npm with features like improved performance and dependency query syntax.

Serverless registry: compatible with npm, this private and scalable registry gives you total control over the distribution of your packages.

These tools could significantly streamline the way developers manage JavaScript packages by providing faster performance and more control over the distribution of private packages.

Party component

If you are a front-end developer working on multiple frameworks, Component Party is your new best friend. This is a tool that compares how common tasks are performed in different libraries such as React, Vue, Svelte and Angular.

With its latest additions (support for Svelte 5 and Angular 17), it is more up to date than ever. It offers a side-by-side comparison of how common tasks (like rendering a component or managing state) are handled in libraries like React, Vue, and Svelte. This makes it easy to learn or change frameworks without wasting time going through documentation.

The AI ​​framework debate

With tools like Replit, Cursor, v0 and others generating working code almost instantly, a new debate is brewing: will frameworks still matter in the future?

Speed ​​vs Structure: AI-generated code could reduce reliance on traditional frameworks for some projects, but frameworks will likely remain essential for larger, more complex applications. The real question is how frameworks will evolve alongside these AI tools.

Future Impact: As AI advances, we may see a change in the way software is designed: frameworks may evolve or become less relevant. This is definitely something to watch!

Tools and versions you should know

Here are some key tools and releases that deserve a spot on your radar this week:

Parcel 2.13.0: This update includes faster resolution caching (which speeds up builds by improving how dependencies are resolved) and adds support for glob in package.json, allowing you to more easily match patterns for files.

Lexical 0.20: Lexical is an extensible text editor framework from Meta, focused on speed, accessibility and cross-platform compatibility. It even has a Swift variant for iOS, making it a must-have if you're building text-heavy apps.

@clerk/nextjs v6: Clerk latest version supports Next.js 15 with async auth(), default static rendering and partial pre-rendering. It is backward compatible with Next.js 14, making it a seamless upgrade for any development team

Storybook 8.4: front-end developers, check it out! Storybook 8.4 now features one-click component testing right in your browser, full support for Svelte 5, and updates to React Native Storybook. Additionally, the bundle size is now 50% smaller, making it faster and lighter.

Jsep: do you want to analyze expressions in JavaScript? jsep is a lightweight library that converts x*(1 2) expressions to AST. It's flexible, lightweight, and supports custom operators, making it perfect for both client-side and server-side projects.

SDK Expo 52: React Native developers, this version is for you! Expo SDK 52 brings React Native 0.76 a 38% performance improvement thanks to its new architecture. This version also includes new libraries, bug fixes and ecosystem improvements.

Upgrade now with npx expo install expo@^52.0.0 --fix
