RaydiantKit is Raydiant's screen signage SDK. Raydiant apps are offline-first React applications that can be configured and published through the Raydiant Dashboard.

Inspired by create-react-app, RaydiantKit makes it easy to develop screen signage applications with zero build configuration.

This document assumes you have some experience with React and async / await.

Installation and Setup

RaydiantKit requires Node 8 or higher. Run node --version to make sure you are running a compatible version.

To create and run your first Raydiant app, run the following commands:

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

The npx command comes installed with Node 5.2+ and will download the create-raydiant-app cli and bootstrap your first Raydiant app. Run npm start to start the app in the RaydiantKit development environment.

You don't need to install Webpack, Babel or ESLint — RaydiantKit conveniently handles all the build configuration for you.

Running create-raydiant-app my-app will scaffold a new app inside a directory called my-app with these files:

├── src
|   └── index.js
|   └── styles.css
├── raydiant.config.js
├── package.json
├── icon.svg
└── thumbnail.svg


Useful npm (or yarn) commands you can run from the app directory:

npm start

Runs your app in the simulator for local development.

npm run build

Bundles a production build of your app to /build. Run this before deploying.

npm run deploy

Deploys a new version of your app from /build.

npm run static

Output the app and simulator as a static site to /static. Useful for sharing a test page before deploying.

npm run test

Runs the jest test suite against files ending in .test.js.


The entry file for Raydiant apps is src/index.js and it must export your app wrapped in the withRaydiantApp higher-order component:

// src/index.js
import { withRaydiantApp } from 'raydiant-kit';

const App = ({
}) => {
  // ...

export default withRaydiantApp(App);

Wrapping your app in withRaydiantApp will inject these props into your app.

Prop Type Definition
presentation object An instance of your application with the user-defined name and values.
ie. { name: 'Weather', values: { city: 'San Francisco' } }
isPlaying boolean Starts at false and becomes true when your app is visible.
playCount number Starts at 0 and increments on every play when your app is looping.
onReady function Call this when your app is ready to be displayed, typically after fetching initial data.
onComplete function Call this when your app has finished displaying, typically after an event like videoend or a user-defined duration.
onError function Call this with an Error object when your app errors.


All Raydiant apps have a raydiant.config.js file to specify how it appears in the Dashboard.

// raydiant.config.js
export default {
  name: 'Weather',
  description: 'Display local weather conditions.',
  callToAction: 'Add Weather',

Config Options

Option type Description
name string The display name of your app.
description string The description of your app.
callToAction string The text to display in the app selector.
properties object Defines the inputs of your application that appear in the presentation builder.
simulator object Simulator-only options. (See the Simulator section for available options.)

Adding an Icon and Thumbnail

To upload an icon and thumbnail, add an icon.svg and thumbnail.svg to the root directory of your app.


Presentation properties define how the user can configure your app from the Dashboard. Use RaydiantKit prop types and their modifiers to create the presentation builder experience.

// raydiant.config.js
import PropTypes from 'raydiant-kit/prop-types';

export default {
  name: 'Weather',
  description: 'Display local weather conditions.',
  callToAction: 'Add Weather',
  properties: {
    city: PropTypes.string('City')
      .helperText('eg. San Francisco, US')
    duration: PropTypes.number('Duration')
      .helperText('Time in seconds.')

All prop types inherit common modifiers for required inputs, default values and helper text / links. The first argument of every prop type is the label of the input.

string('YouTube Video ID')
  .helperText('Where do I get my video id?')
string('Heading Text').maxLength(200);
text('Body Text').maxLength(400);
  .option('light', 'Light')
  .option('dark', 'Dark');
video('Video').maxSize(2000000); // In bytes.
// The first argument is the plural label and the second is the singular label.
array('Categories', 'Category')
    name: string('Category'),
    items: array('Items', 'Item').items({
      name: string('Item'),
      price: number('Price'),

Check out Menu for an example of using array types.


Running npm start from your app directory will start the Raydiant app simulator. You can test various presentation values in the simulator using the presentations option:

// raydiant.config.js
export default {
  // ...
  simulator: {
    presentations: [
        name: 'San Francisco',
        values: { city: 'San Francisco, US', units: 'imperial' },
        name: 'Toronto',
        values: { city: 'Toronto, CA', units: 'metric' },
        name: 'Sydney',
        values: { city: 'Sydney, AU', units: 'metric' },
        name: 'Not Found',
        values: { city: 'Not found' },
      { name: 'New Presentation' },

The active presentation is injected into your app's props:

// src/index.js
import { withRaydiantApp } from 'raydiant-kit';

const Weather = ({ presentation, isPlaying, onReady, onComplete, onError }) => {
  // presentation = {
  //   name: 'San Francisco',
  //   values: {
  //     city: 'San Francisco, CA',
  //     units: 'imperial',
  //     duration: 10,
  //   }
  // }
  // ...

export default withRaydiantApp(Weather);

File Uploads

Raydiant apps can use files uploaded through the Dashboard. To accept files, your app must define a file presentation property.

// raydiant.config.js
import { image, video, file } from 'raydiant-kit/prop-types';
export default {
  // ...
  properties: {
    image: image('Image'),
    video: video('Video'),
    pdf: file('PDF').contentTypes(['application/pdf']),

The url of the upload will be available on the file prop.

// src/index.js
import React from 'react';
import { withRaydiantApp } from 'raydiant-kit';

// Render the image and call onReady when it has loaded.
const PictureApp = ({ presentation, onReady }) => (
  <img src={presentation.values.image.url} onLoad={onReady} />

export default withRaydiantApp(PictureApp);

Local Files

You can test local files by adding them to a files directory in the root directory of your app. The relative url can be referenced from your simulator presentations.

// raydiant.config.js
export default {
  // ...
  simulator: {
    presentations: [{ name: 'Video', values: { url: 'video.mp4' } }],

Check out Video Player for an example of handling file uploads.

Environment Variables

Environment variables are injected at build time and must be prefixed with RAYDIANT_APP_ to access them in your app.

You can add environment variables in a .env file in the root directory the app.

# .env
// src/index.js
const apiKey = process.env.RAYDIANT_APP_WEATHER_API_KEY;

You can also add environment specific environment variables.

  • .env.development will be loaded when running the simulator for local development.
  • .env.production will be loaded when building for deployment.
  • .env.test will be loaded when running the test suite.

.env files should be checked into source control because they should not contain any values that can't be injected into client code.

Browser Support

The Raydiant device runtime is Chromium based so at minimum your app needs to support the latest version of Chrome. It is also recommended that you also develop your app against the Chrome browser.

The Raydiant Dashboard will also load a preview of your app while creating or editing a presentation and supports Chrome, Safari, Edge and IE11. Your app should work with these browsers or provide graceful fallbacks if they don't.

Deploying to the Dashboard

RaydiantKit is currently in closed beta, contact and request an API token and app id to deploy your app.


The examples are published so you can play around with them online. To run them locally you will need to install yarn and clone the repository.
