What it is

Rspack is a Rust-based bundler for web applications that replaces webpack with significantly faster build times while maintaining webpack-compatible APIs and plugin/loader ecosystems. It provides tree-shaking, minification, Module Federation support, and lightning-fast HMR (hot module reloading) through an incremental compilation mechanism built into its Rust core. Monorepo structure: packages/rspack/src/ contains the JavaScript/TypeScript bindings (Compiler.ts, Compilation.ts, ModuleGraph.ts, ChunkGraph.ts) that wrap the Rust engine; crates/ (visible in workspace members) holds the Rust implementations; packages/rspack/src/builtin-loader/ and builtin-plugin/ contain swc-based…

Start here

Open these first:

• packages/rspack/src/Compiler.ts — Main entry point for the Rspack bundler orchestrating compilation lifecycle and coordinating with the Rust backend.
• packages/rspack/src/Compilation.ts — Core compilation state machine managing modules, chunks, and code generation results during the build process.
• packages/rspack/src/ModuleGraph.ts — Tracks module dependencies and relationships; essential for understanding how Rspack models the dependency tree.
• packages/rspack/src/NormalModuleFactory.ts — Factory for creating and resolving NormalModule instances; critical for the module resolution and loading pipeline.
• packages/rspack/src/builtin-plugin/JavascriptModulesPlugin.ts — Handles JavaScript code generation and module concatenation; fundamental to output generation.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Exact setup commands cannot be reliably inferred from provided data. Based on Rust workspace structure (Cargo.toml present) and TypeScript packages: Verify the official documentation first, then likely: `git clone h…

Daily commands:

Commands not reliably extractable from provided data. Check packages/rspack/package.json for npm scripts (likely npm run build, npm run dev) and Cargo.toml for Rust build targets. Refer to official documentation…

…shortened for this brief.

Key cautions & unknowns

• TypeScript edition is listed as '2024' in Cargo.toml, which is unusual (likely a non-standard field). The workspace uses feature-resolver v2 for Cargo, which affects how optional features are resolved across the…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
