WebContainer Snapshot Utils
This package exposes utilities to help build filesystem snapshots for usage with the WebContainer API.
How To
This package is meant to be used on the server-side to build a binary snapshot of a given folder.
import { snapshot } from '@webcontainer/snapshot';
const sourceSnapshot = await snapshot(sourceFilesFolder);
// Express-like handler
function getSnapshot(req: Request, res: Resonse) {
res.setHeader('content-type', 'application/octet-stream').send(sourceSnapshot);
}
// SvelteKit-like handler
function getSnapshot(req: Request) {
return new Response(sourceSnapshot, {
headers: {
'content-type': 'application/octet-stream',
},
});
}
This snapshot can later be sent to a WebContainer API-based frontend application.
import { WebContainer } from '@webcontainer/api';
const webcontainer = await WebContainer.boot();
const snapshotResponse = await fetch('/snapshot');
const snapshot = await snapshotResponse.arrayBuffer();
await webcontainer.mount(snapshot);
