@bytecodealliance/jco-std

This @bytecodealliance/jco sub-project contains shared functionality and reusable libraries that can be used for building WebAssembly Components in Javascript.

WebAssembly Components are a WebAssembly binaries that use the Component Model, an evolving architecture for interoperabl WebAssembly libraries, aplications and environments.

WebAssembly components can be used from server side applications and in the browser, and @bytecodealliance/jco-std contains shared functionality and helpers for both environments.

[!WARNING] Browser support is considered experimental, and not currently suitable for production applications.

Quickstart

@bytecodealliance/jco-std can be used in varied ways via it's exports, this section contains some examples of how to get started quickly.

Hono Adapter

To use @bytecodealliance/jco-std to make building Hono applications easier with WebAssembly, use the @bytecodealliance/jco-std/http/adapters/hono export:

import { Hono } from 'hono';

import { fire } from '@bytecodealliance/jco-std/wasi/0.2.x/http/adapters/hono/server';

const app = new Hono();
app.get('/', () => "Hello World!");

fire(app);

// Although we've called `fire()` with wasi HTTP configured for use above,
// we still need to actually export the `wasi:http/incoming-handler` interface object,
// as componentize-js will be looking for the ES module export.
export { incomingHandler } from '@bytecodealliance/jco-std/wasi/0.2.x/http/adapters/hono/server';

[!NOTE] We use @bytecodealliance/jco-std/wasi/0.2.x, but if you'd like to use a specific version, you can use an explicitly versioned export like @bytecodealliance/jco-std/wasi/0.2.6.

Note that using 0.2.x is similar to using latest, it may change at any library update.
