rsnext/examples/with-webassembly

WebAssembly example

This example shows how to import WebAssembly files (.wasm) and use them inside of a React component that is server rendered. So the WebAssembly code is executed on the server too. In the case of this example we're showing Rust compiled to WebAssembly.

How to use

Using create-next-app

Execute create-next-app with npm or Yarn to bootstrap the example:

npm init next-app --example with-webassembly with-webassembly-app
# or
yarn create next-app --example with-webassembly with-webassembly-app

Download manually

Download the example:

curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-webassembly
cd with-webassembly

Install it and run:

This example uses Rust compiled to wasm, the wasm file is included in the example, but to compile your own Rust code you'll have to install Rust.

npm install
npm run dev
# or
yarn
yarn dev

To compile src/add.rs to add.wasm use npm run build-rust.

Deploy it to the cloud with Vercel (Documentation).
