isLoaded

isLoaded: boolean

This is set to true when the persistence provider loaded the document from the database or when the sync event fires. Note that not all providers implement this feature. Provider authors are encouraged to fire the load event when the doc content is loaded from the database.

isSynced

isSynced: boolean

This is set to true when the connection provider has successfully synced with a backend. Note that when using peer-to-peer providers this event may not provide very useful. Also note that not all providers implement this feature. Provider authors are encouraged to fire the sync event when the doc has been synced (with true as a parameter) or if connection is lost (with false as a parameter).

get()

get(name, TypeConstructor?): AbstractType<any>

Define a shared data type.

Multiple calls of y.get(name, TypeConstructor) yield the same result and do not overwrite each other. I.e. y.define(name, Y.Array) === y.define(name, Y.Array)

After this method is called, the type is also available on y.share.get(name).

Best Practices: Define all types right after the Yjs instance is created and store them in a separate object. Also use the typed methods getText(name), getArray(name), ..

Parameters

• name: string

• TypeConstructor?: Function

The constructor of the type definition. E.g. Y.Text, Y.Array, Y.Map, ...

Returns

AbstractType<any>

The created type. Constructed with TypeConstructor

Example

const y = new Y(..)
  const appState = {
    document: y.getText('document')
    comments: y.getArray('comments')
  }

load()

It is safe to call load() multiple times.

Returns

void

toJSON()

toJSON(): Object

Converts the entire document into a js object, recursively traversing each yjs type Doesn't log types that have not been defined (using ydoc.getType(..)).

Returns

Object

Deprecated

Do not use this method and rather call toJSON directly on the shared types.

---

transact()

transact<T>(f, origin?): T

Changes that happen inside of a transaction are bundled. This means that the observer fires after the transaction is finished and that all changes that happened inside of the transaction are sent as one message to the other peers.

Type parameters

• T

Parameters

• f: (arg0) => T

The function that should be executed as a transaction

• origin?: any

Origin of who started the transaction. Will be stored on transaction.origin

Returns
