2022 JavaScript Rising Stars

Overall winner: Bun 🏆

The trendiest project of the year is Bun: a new JavaScript runtime that is all about performance and great DX. Its popularity exploded this summer with the first Beta release: +20,000 stars on GitHub in one month. We have never seen such an explosion since we started tracking projects at Best of JS.

So what makes Bun special? Like Deno, the overall winner two years ago, it provides first-class support for TypeScript.

But Bun is not just a runtime. It's also:

• a package manager (think Yarn, NPM, PNPM)
• a building tool (think Webpack, ESBuild, Parcel)
• a test runner
• ... and many other things!

So Bun can install your dependencies reading your package.json. Bun can also run your scripts. It does everything faster than anything else.

Bun is a fresh take on many aspects of the JavaScript ecosystem, focusing on performance.

It prioritizes standard Web APIs like Fetch. It supports many of the Node.js APIs, making it compatible with most NPM packages. It may not be "production-ready" (lack of Windows support) yet, but it's a very promising tool. Compared to Deno, the ecosystem is pretty new, but it already has a web framework called Elysia that claims to be the fastest HTTP framework.

The most incredible thing about Bun is that its creator, Jarred Sumner implemented all those features from scratch using a low-level language called Zig.

Tauri

In fifth in 2021, Tauri was even more popular in 2022 with 30,000 new stargazers. It's a project written in Rust to create cross-platform desktop applications using web technologies.

The version 1.0 was released in June.

It's built with security and performance in mind. Compared to Electron, it has a small footprint as the developer has to specify the API and capabilities required by the application.

React and Next.js

In third and forth React and Next.js got similar numbers, with almost 20,000 new stargazers.

Next.js 13, released in October, leverages the React Server Components introduced by React 17 in 2020.

Andrew Clark, one of the maintainers of React made a bold statement about their adoption in the future in this thread:

Server Components is the future of React and our goal is to spread this architecture to the entire React ecosystem, regardless of framework

Vite

In fifth Vite is the trendiest tool to build applications based on web technologies while providing an amazing developer experience.

It had two major releases this year (v3 in July and v4 in December).

It powers more and more projects including the frameworks SvelteKit and Qwik and the test runner Vitest.

React is still the King in 2022 but Vue.js is close in terms of popularity if you consider that Vue.js stars are split between v2 and v3 repositories.

The main change is the raise of Qwik at the position 2. Qwik is similar to React, it also uses components written in JSX for templates but the main difference is the focus on shipping the least amount of JavaScript in the browser.

It's part of the trend of "Zero baseline JavaScript" frameworks. Sites and applications are often bloated with heavy JavaScript assets that affect the performance in the browser: even if the page is rendered on the server, users have to wait until JavaScript is loaded, parsed and executed to be able to interact with the page.

Instead of relying on hydration to bring interactivity to pages generated on the server, Qwik uses a technique called resumability to deliver HTML that is instantly interactive. It works by serializing the state of the application in the HTML itself.

The project is led by Miško Hevery, the creator of AngularJS whose slogan was "HTML enhanced for web apps" while Qwik is "the HTML-first framework"... somehow the same intention of building apps on top of the good old HTML.

2022 saw React become more opinionated.

React is still a library that can be sprinkled into any webpage, but it’s also evolved into an architecture frameworks can follow to create interactive, resilient, and performance frontend patterns.

The React 18 release (in March) included concurrent features and APIs largely providing architecture patterns for frameworks. Consider React Server Components, designed to be implemented in conjunction with these new architecture patterns. Some conventions have now been standardized between React frameworks (e.g. use client) and others are being incubated (e.g. async/await in Server Components) during beta periods.

In 2023, we’ll continue to see innovations using React’s new primitives, but also in the larger React ecosystem. The growth of libraries for improved type safety, as well as UI components, will continue to rise.

This year we got many major updates of Vue. Vue 2.7 brings the native Composition API support and <script setup> syntax back to Vue 2.

Making the transition to Vue 3 much smoother. <script setup> became stable and generally available, and the new experimental "Reactivity Transform" is right around the corner to enhance the DX even further. The team is also working on a new rendering strategy called "Vapor mode", inspired by Soild.js, which could make Vue even more performant on critical parts.

The stable releases of Nuxt 3 and Vuetify 3 indicate that Vue's ecosystem is mature enough. Vite multiplies during the year, and we see a lot of adoption from Vue users, from create-vue, Nuxt, Quasar, Astro and many new frameworks. With the power of Vite, Vue users also got a much better testing/developing experience with Vitest and Histoire. We also see creative usage of Vue, like rendering a command line interface with vue-termui.

What a year for the improvements of DX! Hope the community can find those tools boosting their workflows, and looking forward to seeing what's coming next!

The boundary between front-end and backend frameworks is a bit blurry as there is a strong trend to do more things on the server (including rendering and routing) compared to the SPA approach, where the backend is only responsible for the API. So this section includes full-stack frameworks, meta frameworks and backend frameworks.

Next.js

Like last year, Next.js leads the rankings, the version 13 brought big features including the React Server Components and a new filesystem structure using the app folder that lets developers co-locate their code related to their features and handle nested routes in a powerful way.

tRPC and the create-t3-app

The biggest change is the rise of tRPC, in second. Forget about REST versus GraphQL: there is also the JSON RPC 2.0 protocol that powers tRPC. It really shines with its feature to import the types defined in the server from the client, to provide "end-to-end type safety".

In fourth the project create-t3-app combines tRPC, Next.js and Tailwind CSS in a popular boilerplate.

Astro

In third Astro burst into the scene in 2021 as a static site generator and made the concept of partial hydration popular.

The Astro team's meticulous attention to creating smooth developer experiences is highlighted with the release of Astro 1.0.

The "baked-in" integration of the new SSR support with any frontend tool (like React and SCSS) makes web app development feel too crisp!

Remix

In fifth, Remix keeps growing at a fast pace. It was open sourced in 2021 and just one year later it was acquired by Shopify.

In the blog post The Web Next Transition Kent C. Dodds did a great job to explain the pattern that makes Remix special.

Instead of relying on static generation of pages, Remix leverages distributed computing and native browser features to deliver great performance in the browser and an amazing Developer Experience.

This year, Vite continues its momentum and has become one of the most popular frontend tools. Its precursor Snowpack is no longer maintained and recommends using Vite. Its adoption is not limited to the Vue ecosystem: Vite is used in SvelteKit, Storybook, Vitest or even as a modern alternative to Create-React-App.

We have also seen the rise of build tools for monorepo with Nx and Turborepo. Nwrl (the company behind Nx) has taken over maintenance of Lerna and released Lerna 6 which enables Nx optimizations by default.

Although Babel remains popular, swc and esbuild have been widely adopted by many projects and meta-frameworks. These new tools allow to significantly improve build and transpilation performances. swc is a more modular choice, as it offers a plugin system.

Vercel announced Turbopack (alpha), a new very fast bundler in Rust on which Tobias Koppers (original creator of Webpack) is working.

The Rome toolchain has released its first stable version, starting with a linter and a formatter with interesting properties. The adoption is shy, but could increase this year.

Many frontend tools in Rust should make news this year:

• Lightning CSS (formerly Parcel CSS): a faster CSS toolchain
• Speedy TypeScript type checker: a faster alternative to tsc
• mdxjs-rs: a faster MDX implementation

In 2022, the use of JavaScript for building native apps saw significant progress, as exemplified by the breakthrough success of projects like the new Replit mobile app and the integration of React Native into the Shopify app. In fact, React Native-based repositories made up 7 out of the top 10 rising stars in the mobile category this year. This comes as React Native earns its 7th consecutive year as the #1 most starred mobile repo.

In addition to the success of React Native, there was also an exciting trend towards the adoption of popular web patterns, such as the growing use of Tailwind CSS with NativeWind (#10) and advancements in universal Skia rendering (#3). The integration of classic web features, like File System-based routing in Expo (#2), further demonstrated that native app development is becoming increasingly more accessible to web developers.

It’s difficult to predict what the future holds for mobile development, but if the past year is any indication, the divide between web and native app development should continue to decrease drastically in 2023.
