Connect Backbone Models and Collections to React.


npm install connect-backbone-to-react or yarn add connect-backbone-to-react in your React/Backbone project. See code samples below to how to integrate into your code.


Edit connectBackboneToReact


const UserModel = Backbone.Model.extend();
const UserCollection = Backbone.Collection.extend({ model: UserModel });

const userInstance = new UserModel({ name: "Harry", laughs: true });
const anotherUserInstance = new UserModel({ name: "Samantha", laughs: false });
const userCollection = new UserCollection([userInstance, anotherUserInstance]);

class MyComponent extends React.Component {
  render() {
    return (
        <p>My user laughs: {this.props.doesUserLaugh ? "yes" : "no"}</p>
          onClick={() => this.props.setUserLaughs(!this.props.doesUserLaugh)}
          Toggle Laughing User
        <h4>All Users</h4>
          { => (
            <li key={}>{}</li>

// Maps Models to properties to give to the React Component. Optional.
// Default behavior is to call `.toJSON()` on every Model and Collection.
// Second argument are props given to the React Component.
const mapModelsToProps = (models, props) => {
  const { user, allUsers } = models;
  const { showOnlyLaughingUsers } = props;

  // Everything returned from this function will be given as a prop to your Component.
  return {
    doesUserLaugh: user.get("laughs"),
    users: showOnlyLaughingUsers
      ? allUsers.toJSON().filter(user => user.laughs === true)
      : allUsers.toJSON(),
    setUserLaughs(newVal) {
      user.set("laughs", newVal);

// Options.
const options = {
  // Should our event handler function be wrapped in a debounce function
  // to prevent many re-renders.
  debounce: false, // or `true`, or a number that will be used in the debounce function.

  // Define what events you want to listen to on your Backbone Model or Collection
  // that will cause your React Component to re-render.
  // By default it's ['all'] for every Model and Collection given.
  events: {
    user: ["change:name", "change:laughs"]
    // You can disable listening to events by passing in `false` or an empty array.

  // Define what modelTypes you expect to be contained on your `modelsMap` object.
  // Useful for validating that you'll be given what model type you expect.
  // Uses instanceof, and throws an error if instanceof returns false.
  // By default no modelTypes are defined.
  modelTypes: {
    user: UserModel,
    allUsers: UserCollection

  // Enable access to the wrapped component's ref with the `withRef` option.
  // You can then access the wrapped component from the connected component's `getWrappedInstance()`.
  // This is similar to react-redux's connectAdvanced() HOC.
  // By default, `withRef` is false.
  withRef: true

const { connectBackboneToReact } = require("connect-backbone-to-react");

// Create our Connected Higher order Component (HOC).
const MyComponentConnected = connectBackboneToReact(

Now that you've created your HOC you can use it!

// Map your Backbone Model and Collections to names that will be provided to
// your mapModelsToProps function.
const modelsMap = {
  user: userInstance,
  allUsers: userCollection

  // Pass the modelsMap to the HOC via the models prop.
  <MyComponentConnected models={modelsMap} showOnlyLaughingUsers={true} />,


Alternatively you might have a tree of connected Components. We shouldn't pass that modelsMap object from one component to another. Instead we can take inspiration from react-redux's Provider component.

const { BackboneProvider } = require('connect-backbone-to-react');

const modelsMap = {
  user: userInstance,
  allUsers: userCollection,

  // Pass the modelsMap to the BackboneProvider via the models prop.
  // It will then get shared to every child connected component via React's context.
  <BackboneProvider models={modelsMap}>
      <MyComponentConnected />

Rendering React Within Backbone.View

This library's focus is on sharing Backbone.Models with React Components. It is not concerned with how to render React Components within Backbone.Views. The React docs provide a possible implementation for this interopt.

Local development

To develop this library locally, run the following commands in the project root directory:

  1. npm run watch. The library will be automatically compiled in the background as you make changes.
  2. npm link and then follow the instructions to use the local version of this library in another project that uses connect-backbone-to-react.

Run npm test to run the unit tests.

Releasing a new version

  1. Make sure you have up to date node_modules before you proceed. Can be done via npm ci
  2. Update the version via: npm run release -- --release-as=major|minor|patch
  3. Optionally manually edit the revised file. Commit changes.
  4. Follow the directions from step 2: run git push --follow-tags origin master; npm publish to publish
  5. Rejoice!
