React setup

To get you started as quickly as possible, you can follow these instructions. If you've already gotten your React app up and running, please head straight to the Setting up Headless Ninja section.

Please also make sure you've followed the Drupal setup guide.

Setting up your React app

Open up your terminal and make sure you've got Node.js with version >= 6 installed. Run node -v to verify. Head over to the Node.js website to download or update.

After Node.js is installed, run the following commands. They will make sure your React app is running and will open up your brand new app in your browser.

Please make sure to replace my-app by your own app name.

npx create-react-app my-app
cd my-app
npm start

Now open up the my-app folder in your editor of choice.

Setting up Headless Ninja

To get started, run the following command from your my-app folder

npm install hn hn-react react-router-dom --save

Or with Yarn

yarn add hn hn-react react-router-dom

We'll now do two things:

  1. Connect React to the Drupal site
  2. Use React Router to watch for location changes
  3. Render the page title from Drupal

Start by opening up src/index.js. In this file we'll

  • Initialize Headless Ninja with HN's site.initialize()
  • Wrap our App in react-router's <BrowserRouter />
  • Tell the React app to wait for our Drupal to respond with data by wrapping it in HN's waitForHnData().

Replace all contents of src/index.js with

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router } from 'react-router-dom';
import { waitForHnData, site } from 'hn-react';
import App from './App';

(async () => {
  site.initialize({ url: '' });

    await waitForHnData(
        <App />

Please replace "" with your Drupal url.

Now open up src/App.js. In this file we'll

  • Make sure HN updates whenever your visitor navigates
  • Map the Content Type we get from Drupal to a React component

Replace all contents of src/App.js with

import React, { Component } from 'react';
import { DrupalPage } from 'hn-react';
import { withRouter } from 'react-router-dom';

class App extends Component {
  render() {
    const { location: { pathname, search } } = this.props;

    return (
          node__article: Article,
          node__product: Product,
        url={pathname + search}

const Article = ({ entity }) => <h1>{entity.title}</h1>;
const Product = ({ entity }) => <h1>{entity.title}</h1>;

export default withRouter(App);

Now head back to your browser, and you should see the page title as you've entered it in your Drupal homepage.

That's it! Follow the other guides for more detailed instructions and documentation:
