Show HN: I rewrote my notepad calculator as a local-first app with CRDT syncing
Show HN: I rewrote my notepad calculator as a local-first app with CRDT syncing I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written.<p>Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which <i>should</i> make it relatively easy to get document sharing working too.<p>[1] <a href="https://automerge.org/" rel="nofollow">https://automerge.org/</a>
