Installation

You can install this package from npm using Bun.

bun add @jcbhmr/bun-build-compile-target-starlingmonkey-wasip2-wasm32

[!WARNING] This package only works with Bun. It does not work with Node.js, Deno, or the browser.

Usage

Similar to Bun.build()/bun build, you can use this package either via CLI or programmatically as a library. The recommended way is to start with the CLI in your package.json scripts section and later use the library via bun ./build.ts if you need plugins or other dynamic functionality.

CLI

package octocat:[email protected];
interface greetings {
    greeting-for: func(name: string) -> string;
}
world hello-world {
    export greetings;
}

export const greetings = {
    greetingFor(name: string): string {
        return `Hi ${name}! How are you today?`;
    },
}

bunx bun-build-compile-target-starlingmonkey-wasip2-wasm32 \
    ./index.ts \
    --starlingmonkey-wit-path ./package.wit \
    --outfile ./app.wasm

wasmtime --invoke 'greeting-for("Alan Turing")' ./app.wasm

"Hi Alan Turing! How are you today?"

Library

const output = await bunBuildCompileTargetStarlingMonkeyWasiP2Wasm32({
    entrypoints: ['./index.ts'],
    compile: {
        starlingmonkey: {
            witPath: './package.wit',
        },
        outfile: './app.wasm',
    },
});
