Changes

The Changes class is responsible for managing changes in a store. It provides methods for changing components, retrieving values, resetting changes, and updating or inserting components.

Example Usage

const store = new Storage();
const changes = new Changes(store);


// Change a component
changes.changeComponent('componentId', 'propertyKey', 'newValue', 'prevValue');


// Retrieve the changes of a value
const diffs = changes.getValue('componentId', 'propertyKey', 'storedValue');


// Reset the changes
changes.reset();


// Update or insert a component
changes.upsertComponent('componentId', 'propertyKey', 'newValue', '_prevValue');

Methods

  • changeComponent(id, key, newValue, prevValue, isAsyncStorage): Changes a component in the current store. Returns a promise that resolves to the new value.
  • getValue(id, key, storedValue): Retrieves the changes of a value. Returns the diffs.
  • reset(changes): Resets the changes to a new set of changes or an empty object if no changes are provided. Returns the instance of the Changes class.
  • upsertComponent(id, key, newValue, _prevValue, isAsyncStorage): Updates an existing component or inserts a new one if it doesn’t exist in the current store. Returns a promise that resolves to the new value.

Fields

  • store: StorageInterface: The store in which changes are to be managed.
  • diffs: Record<string, any>: The diffs of the changes.
