rollup-plugin-rust

library1.2.0jsnpmunverified

A Rollup plugin that compiles Rust code into WebAssembly modules, enabling seamless interop between Rust and JavaScript projects. Version 1.2.0, currently in active development with no recent updates. Requires Node >= 8.9.0, Rollup >= 0.64.0, and Rust nightly with wasm32-unknown-unknown target. Supports various export modes (WebAssembly.Instance, WebAssembly.Module, buffer), release/debug builds, and custom include/exclude patterns. Differentiates from other WASM plugins by focusing specifically on Rust compilation via the rustc compiler, offering tight integration with Rollup's build pipeline.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import rust from 'rollup-plugin-rust'

✗ const rust = require('rollup-plugin-rust').default

The plugin exports a default function. Use ESM import syntax.

rust (default import with options)

✓ import rust from 'rollup-plugin-rust'; rust({ release: false })

✗ import { rust } from 'rollup-plugin-rust'

The default export is a function that takes an options object.

RustOptions (type)

✓ import type { RustOptions } from 'rollup-plugin-rust'

TypeScript definitions are shipped; use type import for options interface.

RustPlugin (type alias)

✓ import type { RustPlugin } from 'rollup-plugin-rust'

The plugin function returns a Rollup plugin object; this type may be useful for generic typing.

Shows a minimal Rollup configuration using the plugin to compile Rust to WASM, and how to import and use the WASM module in JavaScript.

// rollup.config.js import rust from 'rollup-plugin-rust'; export default { input: 'src/main.js', output: { file: 'dist/bundle.js', format: 'esm' }, plugins: [rust({ release: true })] }; // lib.rs // #[no_mangle] // pub fn add(a: i32, b: i32) -> i32 { // a + b // } // src/main.js import wasm from './lib.rs'; export async function increment(a) { const { instance } = await wasm; return instance.exports.add(1, a); }

Debug

Known issues

breakingRequires Rust nightly channel to compile WASM targets.

fix

Use 'rustup default nightly' and install wasm32-unknown-unknown target.

affects: >=1.0.0

gotchaOnly supports wasm-related targets (wasm32-unknown-unknown, wasm32-unknown-emscripten).

fix

Set 'target' option to a valid WASM target; other targets will fail compilation.

affects: >=1.0.0

gotchaThe plugin compiles Rust code via rustc, which can be slow on first run due to crate compilation.

fix

Consider using caching or incremental compilation in Rust (nightly feature).

affects: >=1.0.0

deprecatedNode v8 is EOL; plugin may not work on newer Node versions due to dependencies.

fix

Upgrade Node to v12 or later and test compatibility; consider using an alternative plugin with newer maintenance.

affects: >=1.0.0

gotchaImport path must point to a .rs file; the plugin resolves Rust files by extension.

fix

Use './lib.rs' (with extension) in import statements.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Could not resolve 'lib.rs' from 'src/main.js'

The plugin's include pattern does not cover the Rust file, or the file path is incorrect.

fix

Ensure 'lib.rs' exists at the specified path and that 'include' option in plugin configuration matches the file.

Error: wasm32-unknown-unknown target is not installed

The required Rust compilation target is missing.

fix

Run 'rustup target add wasm32-unknown-unknown' and ensure Rust is on nightly channel.

TypeError: rust is not a function

Improper import; using CommonJS require without .default or importing as named export.

fix

Use 'import rust from "rollup-plugin-rust"' or 'const rust = require("rollup-plugin-rust").default'.

Error: rollup-plugin-rust: No Rust source file provided

The plugin did not match any Rust files in the Rollup build.

fix

Verify that your import statement points to a .rs file and the file exists.
