+Shared Types
+By now, we have learned how to make an editor collaborative and how to sync document updates using different providers. But we haven't covered the most unique feature of Yjs yet: Shared Types.
+
+Shared types allow you to make every aspect of your application collaborative. For example, you could sync your react-state using shared types. You can sync diagrams, drawings, and even whole 3d worlds using shared types to automatically resolve conflicts.
+
+Shared types are similar to common data types like Array, Map, or Set. The only difference is that they automatically sync & persist their state (using the providers) and that you can observe them.
+
+We already learned about the Y.Text type that we "bound" to an editor instance to automatically sync a rich-text editor. Yjs supports many other shared types like Y.Array, Y.Map, and Y.Xml. A complete list, including documentation for each type, can be found in the shared types section.
+
+Shared type instances must be connected to a Yjs document so we can sync them. First, we define a shared type on a Yjs document. Then we can manipulate it and observe changes.
+
+Copy
+import * as Y from 'yjs'
+
+const ydoc = new Y.Doc()
+// Define an instance of Y.Array named "my array"
+// Every peer that defines "my array" like this will sync content with this peer.
+const yarray = ydoc.getArray('my array')
+
+// We can register change-observers like this
+yarray.observe(event => {
+  // Log a delta every time the type changes
+  // Learn more about the delta format here: https://quilljs.com/docs/delta/
+  console.log('delta:', event.changes.delta)
+})
+
+// There are a few caveats that you need to understand when working with shared types
+// It is best to explain this in a few lines of code:
+
+// We can insert & delete content
+yarray.insert(0, ['some content']) // => delta: [{ insert: ['some content'] }]
+// Note that the above method accepts an array of content to insert.
+// So the final document will look like this:
+yarray.toArray() // => ['some content']
+// We can insert anything that is JSON-encodable. Uint8Arrays also work.
+yarray.insert(0, [1, { bool: true }, new Uint8Array([1,2,3])]) // => delta: [{ insert: [1, { bool: true }, Uint8Array([1,2,3])] }]
+yarray.toArray() // => [1, { bool: true }, Uint8Array([1,2,3]), 'some content']
+// You can even insert Yjs types, allowing you to create nested structures
+const subArray = new Y.Array()
+yarray.insert(0, [subArray]) // => delta: [{ insert: [subArray] }]
+// Note that the above observer doesn't fire when you insert content into subArray
+subArray.insert(0, ['nope']) // [observer not called]
+// You need to create an observer on subArray instead
+subArray.observe(event => { .. })
+// Alternatively you can observe deep changes on yarray (allowing you to observe child-events as well)
+yarray.observeDeep(events => { console.log('All deep events: ', events) })
+subArray.insert(0, ['this works']) // => All deep events: [..]
+// You can't insert the array at another place. A shared type can only exist in one place.
+yarray.insert(0, [subArray]) // Throws exception!
+The other data types work similarly to Y.Array. The complete documentation is available in the shared types section that covers each type and the event format in detail.
+
+PAGE
+Shared Types
+Caveats
+There are some things that are not possible with shared types, but that are possible with normal data types. Most importantly, it is not possible to move a type that was inserted into a Yjs document to a different location. The other important caveat is that you shouldn't modify JSON that you inserted or retrieved from a shared type. Yjs doesn't clone the inserted objects to improve performance. So when you modify a JSON object, you will actually change the internal representation of Yjs without notifying other peers of that change.
+
+Copy
+// 1. An inserted array must not be moved to a different location
+yarray.insert(0, ymap.get("my other array") as Y.Array) // will throw an error
+// 2. It is discouraged to modify JSON that is inserted or retrieved from a Yjs type
+//    This might lead to documents that don't synchronize anymore.
+const myObject = { val: 0 }
+ymap.set(0, myObject)
+ymap.get(0).val = 1 // Doesn't throw an error, but is highly discouraged
+myobject.val = 2 // Also doesn't throw an error, but is also discouraged.
+Transactions
+All changes must happen in a transaction. When you mutate a shared type without creating a transaction (e.g. yarray.insert(..)), Yjs will automatically create a transaction before manipulating the shared object. You can create transactions explicitly like this:
+
+Copy
+const ydoc = new Y.Doc()
+const ymap = ydoc.getMap('favorites')
+
+// set an initial value - to demonstrate the how changes in ymap are represented
+ymap.set('food', 'pizza')
+
+// observers are called after each transaction
+ymap.observe(event => {
+  console.log('changes', event.changes.keys)
+})
+
+ydoc.transact(() => {
+  ymap.set('food', 'pencake')
+  ymap.set('number', 31)
+}) // => changes: Map({ number: { action: 'added' }, food: { action: 'updated', oldValue: 'pizza' } })
+Event handlers and observers are called after each transaction. If possible, you should bundle as many changes in a single transaction as possible. The advantage is that you reduce expensive observer calls and create fewer updates that are sent to other peers.
+
+Yjs fires events in the following order:
+
+ydoc.on('beforeTransaction', event => { .. }) - Called before any transaction, allowing you to store relevant information before changes happen.
+
+Now the transaction function is executed.
+
+ydoc.on('beforeObserverCalls', event => {})
+
+ytype.observe(event => { .. }) - Observers are called.
+
+ytype.observeDeep(event => { .. }) - Deep observers are called.
+
+ydoc.on('afterTransaction', event => {}) - Called after each transaction.
+
+ydoc.on('update', update => { .. }) - This update message is propagated by the providers.
+
+Especially when manipulating many objects, it makes sense to reduce the creation of update messages. So use transactions whenever possible.
