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).

Emit a named event. All registered event listeners that listen to the specified name will receive the event.

---|---|---|
name | string | The event name. |
args | any [] | The arguments that are applied to the event listener. |

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 ​
Parameter | Type | Description |
---|---|---|
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')
}
const y = new Y(..)
const appState = {
document: y.getText('document')
comments: y.getArray('comments')
}

load ​
load():

multiple times.

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 ​

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