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

delta ​

get delta(): Object[]

Compute the changes in the delta format. A Delta) that represents the changes on the document.

Returns ​

Object[]

Source ​

node_modules/.pnpm/yjs@13.6.10/node_modules/yjs/dist/src/types/YText.d.ts:75

keys ​

get keys(): Map<string, Object>

Returns ​

Map<string, Object>

Source ​

node_modules/.pnpm/yjs@13.6.10/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 ​

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

Returns ​

(string | number)[]
