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).
