LocalMutationAction

LocalMutationAction is a type which defines the structure of local mutation actions. You can use it if you use Typescript, for example:

import { LocalMutationAction } from '@redux-requests/core';

function updateBookName(id: string, newName: string): LocalMutationAction {
  return {
    type: 'UPDATE_BOOK_NAME',
    meta: {
      mutations: {
        FETCH_BOOK: {
          updateData: data =>
            data && data.id === id ? { ...data, name: newName } : data,
          local: true,
        },
      },
    },
  };
}

...or if fetchBook is normalized, you could just:

import { LocalMutationAction } from '@redux-requests/core';

function updateBookName(id: string, newName: string): LocalMutationAction {
  return {
    type: 'UPDATE_BOOK_NAME',
    meta: {
      localData: { id, name: newName },
    },
  };
}
