Accessors

changes

get changes(): object

This is a computed property. Note that this can only be safely computed during the event call. Computing this property after other changes happened might result in unexpected behavior (incorrect computation of deltas). A safe way to collect changes is to store the changes or the delta object. Avoid storing the transaction object.

Returns

object

added

added: Set<Item>

deleted

deleted: Set<Item>

delta

delta: object[]

keys

keys: Map<string, object>

Source

node_modules/.pnpm/yjs@13.6.14/node_modules/yjs/dist/src/utils/YEvent.d.ts:117

delta

get delta(): object[]

This is a computed property. Note that this can only be safely computed during the event call. Computing this property after other changes happened might result in unexpected behavior (incorrect computation of deltas). A safe way to collect changes is to store the changes or the delta object. Avoid storing the transaction object.

Returns

object[]

keys

get keys(): Map<string, object>

Returns

Map<string, object>

Source

node_modules/.pnpm/yjs@13.6.14/node_modules/yjs/dist/src/utils/YEvent.d.ts:79

---

path

get path(): (string | number)[]

Computes the path from y to the changed type.

Todo

v14 should standardize on path: Array<\{parent, index\}> because that is easier to work with.

The following property holds:

Example

let type = y
  event.path.forEach(dir => {
    type = type.get(dir)
  })
  type === event.target // => true

Returns

(string | number)[]
