{"library":"parcel-plugin-wasm.rs","title":"Parcel 1.x wasm-bindgen plugin for Rust","description":"parcel-plugin-wasm.rs is a Parcel 1.x bundler plugin designed to integrate Rust projects compiled to WebAssembly (Wasm) using `wasm-bindgen`. It streamlines the development workflow by automatically compiling Rust code with `wasm-pack` when Parcel 1.x builds the project. The latest stable version available is 1.3.0. A key differentiator was its ability to provide zero-configuration Rust/Wasm compilation for Parcel projects at a time when such integration was less mature. However, it is explicitly designed for `parcel-bundler` (Parcel 1.x), which has been officially deprecated and is no longer maintained. Parcel 2.x includes its own `@parcel/transformer-rust` for native Rust/Wasm support, rendering this plugin obsolete for modern Parcel environments.","language":"javascript","status":"abandoned","last_verified":"Wed Apr 22","install":{"commands":["npm install parcel-plugin-wasm.rs"],"cli":null},"imports":["import { foo } from 'path/to/Cargo.toml'","import lib from 'path/to/Cargo.toml'","import type { WasmModule } from 'path/to/Cargo.toml'"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"/* file: my-crate/src/lib.rs */\nextern crate wasm_bindgen;\nuse wasm_bindgen::prelude::*;\n\n#[wasm_bindgen]\npub fn greet(name: &str) -> String {\n format!(\"Hello, {}!\", name)\n}\n\n/* file: src/index.js */\nimport { greet } from '../my-crate/Cargo.toml';\n\ndocument.getElementById('app').innerHTML = `\n
