js-containerregistry

This is a Javascript library for working with container registries. It relies on google/go-containerregistry compiled in WebAssembly.

You should know:

• This library is rather large (~8 MB) due to the size of the wasm binary
• This library will install global polyfills from the Golang WASM execution code. Consider running this library in a web worker.

Usage

When using this library you are responsible for providing an initialization function that returns a WebAssembly.Instance. Different platforms and frameworks provide different utilities for loading WASM binaries. To increase portability, this library does not attempt to load the wasm file on its own.

WASM file location: js-containerregistry/wasm/containerregistry.wasm

Vite

This library integrates particularly well with Vite's handling of WebAssembly.

import {ContainerRegistry} from "js-containerregistry";
import init from "js-containerregistry/wasm/containerregistry.wasm?init";

const cr = new ContainerRegistry(init);
const m = await cr.getManifest("mirror.kontain.me/gcr.io/distroless/static");
console.log(m);
