IndexedDB database adapter for Yjs

Use the IndexedDB database adapter to store your shared data persistently in the browser. The next time you join the session, your changes will still be there.

• Minimizes the amount of data exchanged between server and client
• Makes offline editing possible
• Not supported by all browsers (see mdn)

Use it!

Install this with bower or npm.

Bower

bower install y-indexeddb --save

NPM

npm install y-indexeddb --save

Example

Y({
  db: {
    name: 'indexeddb'
  },
  connector: {
    name: 'websockets-client', // choose the websockets connector
    // name: 'webrtc'
    // name: 'xmpp'
    room: 'Textarea-example-dev'
  },
  sourceDir: '/bower_components', // location of the y-* modules
  share: {
    textarea: 'Text' // y.share.textarea is of type Y.Text
  }
  // types: ['Richtext', 'Array'] // optional list of types you want to import
}).then(function (y) {
  // bind the textarea to a shared text element
  y.share.textarea.bind(document.getElementById('textfield'))
}
