remix-wasm-plugin

This is a Remix plugin that allows you to use WASM modules in remix with no hassle by bundling them as static assets at compile time, improving the speed of your app and allowing for caching of *.wasm files.

Currently doesn't support wasm in the server. Only client-side packages that run in the browser.

Installation

npm i -D remix-wasm-plugin

After installation, run:

npx remix-wasm-plugin init

This command initialises a wasm.config.js file in your remix root that allows you to further configure your Remix + WASM experience.

Add this scripts to your package.json to build your wasm modules when your app is built:

{
  "scripts": {
    "build:wasm": "remix-wasm-plugin build",
    "dev:wasm": "remix-wasm-plugin build"
  }
}

Usage

To use remix-wasm-plugin in your application after initializing you config. file, update your the modules field in the config. with your wasm packages.

The name of the packages should be the same as it appears in your package.json.

/* WASM.config */
module.exports = {
  enabled: true,
  modules: ["my-wasm-package", "my-wasm-package-2", "@remix-run/wasm"]
}

If the package is scoped, include it together in the field. e.g @remix-pwa/client

Import initWithProps from remix-wasm-plugin into your entry.client.{tsx|jsx} file. Wrap the hydrateRoot function with the initWithProps function. After that, you can call functions from your wasm package like any native JS module.

import { initWithProps } from "remix-wasm-plugin";
// importing these should be documented in the wasm package
import init, { wasm } from "my-wasm-package"; 
import init2, { wasm2 } from "my-wasm-package-2";

initWithProps([init, wasm], [init2, wasm2]).then(() => {
  hydrateRoot(
    document, 
    <RemixBrowser />
  );
})

API

initWithProps

This function is used to initialize wasm modules in your application. It takes in arrays of the init function and the wasm file of your wasm package and returns a promise. After initialization, you can call functions from your wasm package anywhere in your Remix application.

import { initWithProps } from "remix-wasm-plugin";
import init, { wasm } from "my-wasm-package";
import init2, { wasm2 } from "my-wasm-package-2";
import init3, { wasm3 } from "my-wasm-package-3";

initWithProps([init, wasm], [init2, wasm2], [init3, wasm3]).then(() => {
  hydrateRoot(
    document, 
    <RemixBrowser />
  );
})

Configuration

Currently there are two configuration options you can set.

enabled: boolean

This option is for wether you want to enable wasm capabilities in your application

modules: string[]

This is an array of wasm modules you want to bundle into your app.
