automerge-repo-storage-origin-private-file-system

An Automerge Repo Storage adapter for using the browser's Origin private file system as storage.

it uses the same speedy optimized filesystem layout as Automerge's own nodefs adapter, and is tested against the same storage adapter tests as the adapters that come with automerge-repo in Chromium and Firefox.

usage

pnpm add automerge-repo-storage-origin-private-file-system

import {BrowserWebSocketClientAdapter} from "@automerge/automerge-repo-network-websocket"
import OriginPrivateFileSystemAdapter from "automerge-repo-storage-origin-private-file-system"
import {Repo} from "@automerge/automerge-repo"

export default async function startAutomerge() {
	const repo = new Repo({
		storage: new OriginPrivateFileSystemAdapter("automerge"),
		network: [new BrowserWebSocketClientAdapter("wss://sync.automerge.org")],
	})
	return repo
}

weaknesses and drawbacks

because of a missing API in Safari's implementation of the Origin private file system, this storage mechanism does not currently work in Safari. there appears to be no indication that they will ever add support for it, but who knows.

perhaps you would find it enjoyable to submit a pull request that uses a WebWorker to do the writing in Safari?
