This project is a wrapper around Yrs and targets Web Assembly bindings.
It's a library used on collaborative document editing using Conflict-free Replicated Data Types. This enables to provide a shared document editing experience on a client devices without explicit requirement for hosting a single server - CRDTs can resolve potential update conflicts on their own with no central authority - as well as provide first-class offline editing capabilities, where document replicas are modified without having connection to each other, and then synchronize automatically once such connection is enabled.
```js import {YDoc, encodeStateVector, encodeStateAsUpdate, applyUpdate} from 'ywasm';
YDoc.prototype.transact = callback => { const txn = this.beginTransaction() try { return callback(txn) } finally { txn.free() } }
const doc = new YDoc() const text = doc.getText('name')
// append text to our collaborative document text.insert(txn, 0, 'hello world')
// simulate update with remote peer const remoteDoc = new YDoc() const remoteText = remoteDoc.getText('name')
// in order to exchange data with other documents // we first need to create a state vector const remoteSV = encodeStateVector(remoteDoc) // now compute a differential update based on remote document's state vector const update = encodeStateAsUpdate(doc, remoteSV) // both update and state vector are serializable, we can pass them over the wire // now apply update to a remote document applyUpdate(remoteDoc, update)
const str = remoteText.toString(txn) console.log(str) ```
