Rspack binding template

🚀 Unlock native Rust speed for Rspack — supercharge your builds, keep every JS feature, zero compromise, no limits.

Features

• 🦀 Write your own Rspack plugins and loaders in Rust
• 🧩 Inherit all Rspack features and JavaScript API
• 🛡️ Secure supply chain with npm provenance
• 📦 Effortless publishing: just set your NPM_TOKEN

Quick Start

📖 Create custom binding

Why?

Rspack achieves high performance by being written in Rust, but using its JavaScript API introduces overhead due to cross-language calls. This can limit performance and access to native Rust features.

Rspack Custom Binding allows you to extend Rspack directly with native Rust code, avoiding the JavaScript layer and unlocking full performance and flexibility.

With custom binding, you can still use the familiar JavaScript API (@rspack/core), but your custom logic runs natively, combining the best of both worlds.
