API

Library provides build function, which takes 4 parameters: redux state part, object type, ID or an array of IDs or null, and options.

If ID is provided in a form of array, multiple objects are fetched. If ID is null, all objects of selected type are fetched.

Option Default Description
eager false Controls lazy loading for the child relationship objects. By default, lazy loading is enabled.
ignoreLinks false redux-object doesn't support remote objects. This option suppresses the exception thrown in case user accesses a property, which is not loaded to redux store yet.
includeType false Include the record type as a property 'type' on each result. This is particularly useful for identifying the record type returned by a polymorphic relationship.
import build from 'redux-object';

const post = build(state.data, 'post', '2620');

console.log(post.id); // -> 2620
console.log(post.text); // -> hello
console.log(post.daQuestion); // -> { id: 295, text: "hello?" }
console.log(post.liker.length); //-> 3
console.log(post.liker[0]); // -> { id: 1, name: "Alice" }

// Other examples

const post = build(state.data, 'post', '2620', { eager: true });
const post = build(state.data, 'post', '2620', { eager: false, ignoreLinks: true });

Child objects are lazy loaded unless eager option is explicitly provided.
