All the custom behavior mentioned in the previous section is already possible if you use the undoable higher-order reducer from the redux-undo library:

import undoable from 'redux-undo'undoable(reducer, options)

import undoable from 'redux-undo'undoable(reducer, {  undoType: 'CUSTOM_UNDO',  redoType: 'CUSTOM_REDO'})

Alternatively, you can filter certain actions:

import undoable, { includeAction, excludeAction } from 'redux-undo'undoable(reducer, { filter: includeAction(SOME_ACTION) })
undoable(reducer, { filter: excludeAction(SOME_ACTION) })

undoable(reducer, { filter: includeAction([SOME_ACTION, SOME_OTHER_ACTION]) })
undoable(reducer, { filter ...
