Why

Rust-powered bundling, 10x faster than webpack, zero-config for common cases. Vite 5 builds 10-20x faster than Webpack (esbuild + Rollup core).

Turborepo and Nx cut monorepo CI times by 60-80% via remote caching and task parallelization.

When

Use for modern web apps needing fast builds. Avoid for webpack-specific plugins.

How

1. npm create rsbuild@latest 2. Configure rsbuild.config.ts 3. npm run build 4. npm run dev 5. Add environment configuration — cp .env.example .env && edit values 6. Run tests — npm test or pnpm test to verify setup 7. Deploy — git push to trigger CI/CD or manual deploy

Example

export default { html: { title: 'My App' }, source: { entry: { index: './src/index.ts' } }, };

Common Problems

⚠Plugin compat — check Rspack plugin support
⚠CSS handling — use built-in CSS loader config
⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

✓Use SWC for JS/TS transformation
✓Leverage Rspack's built-in optimizations
✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is Rsbuild and what projects is it for?

Rsbuild — high-performance build tool powered by Rspack and SWC. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.

How do I spin up a working demo with Rsbuild in 10 minutes?

Two steps: (1) npm create rsbuild@latest; (2) Configure rsbuild.config.ts. Get the local dev server running, then wire one real data source to verify the end-to-end loop.

What is the most common pitfall with Rsbuild and how do I avoid it?

The most common pitfall is: Plugin compat — check Rspack plugin support. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.

What are the best practices for Rsbuild?

Best practices for Rsbuild include: Use SWC for JS/TS transformation; Leverage Rspack's built-in optimizations; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use SWC for JS/TS transformation" — should be set up at project init to avoid costly rework later.

When should I NOT choose Rsbuild?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Rsbuild shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
