How Parcel bundles React Server Components
7/26/2025 Parcel v2.14.0 added support for React Server Components. The release blog post and documentation describe what RSCs are and how to use them with Parcel. This post is a deep dive into the internals: how RSCs integrate with a bundler, what directives like "use client" do internally, how code splitting works and how RSCs improve it, etc. Let's jump in! What does a bundler do? Before we get
How Rolldown Works: Symbol Linking, CJS/ESM Resolution, and Export Analysis Explained
How Rolldown Works: Symbol Linking, CJS/ESM Resolution, and Export Analysis Explained Introduction Rolldown is a high-performance JavaScript bundler written in Rust. While offering full compatibility with the Rollup API, it achieves bundling speeds 10 to 30 times greater. Driven by the need for a single, unified engine for both development and production, the Vite team is developing Rolldown to be
Server Component と Client Component で依存モジュールを切り替える
ちょっとした React Server Component 小ネタ。 Next.js (webpack, Turbopack) で確認しているが、おそらく RSC に対応しているツールであったらどれも変わらないはず。 アプリケーションの package.json の imports セクションに以下のように記載しておく。util の部分は好きな文字列で構わないが # から始めておくこと。 { "imports": { "#util": { "react-server": "./src/util.react-server.ts", "default": "./src/util.default.ts" } } }React Server 環境とそれ以外の環境用、それぞれの実装を用意する。 とりあえず結果が異なることを確認したければ以下のような感じ。 /* ./src/util.default.
Blazing fast development with full-stack frameworks and Cloudflare
Blazing fast development with full-stack frameworks and Cloudflare2024-04-05 Hello web developers! Last year we released a slew of improvements that made deploying web applications on Cloudflare much easier, and in response we’ve seen a large growth of Astro, Next.js, Nuxt, Qwik, Remix, SolidStart, SvelteKit, and other web apps hosted on Cloudflare. Today we are announcing major improvements to ou

Announcing Vite 5
Vite 5.0 is out! November 16, 2023 Vite 4 was released almost a year ago, and it served as a solid base for the ecosystem. npm downloads per week jumped from 2.5 million to 7.5 million, as projects keep building on a shared infrastructure. Frameworks continued to innovate, and on top of Astro, Nuxt, SvelteKit, Solid Start, Qwik City, between others, we saw new frameworks joining and making the ec
JavaScript Macros in Bun | Bun Blog
Two weeks ago, we launched our new JavaScript bundler in Bun v0.6.0. Today we're releasing a new feature that highlights the tight integration between Bun's bundler and runtime: Bun Macros. Macros are a mechanism for running JavaScript functions at bundle-time. The value returned from these functions are directly inlined into your bundle. As a toy example, consider this simple function that return
Turbopack: High-performance bundler for React Server Components and TypeScript codebases - Vercel
Vercel's mission is to provide the speed and reliability innovators need to create at the moment of inspiration. Last year, we focused on speeding up the way Next.js bundles your apps. Each time we moved from a JavaScript-based tool to a Rust-based one, we saw enormous improvements. We migrated away from Babel, which resulted in 17x faster transpilation. We replaced Terser, which resulted in 6x fa
API Reference: Turbopack | Next.js
