Yjs is a framework for optimistic concurrency control and automatic conflict resolution on shared data types. The framework implements a new OT-like concurrency algorithm and provides similar functionality as [ShareJs] and [OpenCoweb]. Yjs was designed to handle concurrent actions on arbitrary complex data types like Text, Json, and XML. We provide a tutorial and some applications for this framework on our [homepage](http://y-js.org/).

* .. P2P message propagation and arbitrary communication protocols
|
||||
* .. arbitrary complex data types
|
||||
* .. offline editing: Changes are stored persistently and only relevant changes are propagated on rejoin
|
||||
* .. AnyUndo: Undo *any* action that was executed in constant time (coming..)
|
||||
* .. offline support: Changes are stored persistently and only relevant changes are propagated on rejoin
|
||||
* .. Intention Preservation: When working on Text, the intention of your changes are preserved. This is particularily important when working offline. Every type has a notion on how we define Intention Preservation on it.

# Y.Map
|
||||
Yjs includes only one type by default - the Y.Map type. It mimics the behaviour of a javascript Object. You can create, update, and remove properies on the Y.Map type. Furthermore, you can observe changes on this type as you can observe changes on Javascript Objects with [Object.observe](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/observe) - an ECMAScript 7 proposal which is likely to become accepted by the committee. Until then, we have our own implementation.

var map = y.set("new_map", Y.Map).then(function(map){

* Every instance of Y is an Y.Map
|
||||
```
|
||||
var y = new Y(options);
|

```
|
||||
* .get(name)
|
||||
* Retrieve the value of a property. If the value is a type, `.get(name)` returns a promise
|
||||
* .set(name, value)
|
||||
* Set/update a property. `value` may be a primitive type, or a custom type definition (e.g. `Y.Map`)
|
||||
* .delete(name)
|
||||
* Delete a property
|
||||
* .observe(observer)
|
||||
* The `observer` is called whenever something on this object changes. Throws *add*, *update*, and *delete* events
|
||||
* .observePath(path, observer)
|
||||
* `path` is an array of property names. `observer` is called when the property under `path` is set, deleted, or updated
|
||||
* .unobserve(f)
|
||||
* Delete an observer
|
||||
|
||||
# A note on intention preservation
|
||||
When users create/update/delete the same property concurrently, only one change will prevail. Changes on different properties do not conflict with each other.

* Apply a delete operation from another user

* Apply an update operation from another user (set/update a property)
