@shopify/app-bridge

You can use Shopify App Bridge to embed apps and channels directly into the Shopify admin, Shopify Mobile, and Shopify POS. Shopify App Bridge helps to reduce your development time by accessing native Shopify features across different platforms, and makes sure that the user experience is consistent wherever merchants are using your app.

Shopify App Bridge is currently being released as an update to all current consumers of the Embedded App SDK. Since it’s backwards compatible, you don't need to update your existing apps for them to support Shopify App Bridge.

Installation

You can install Shopify App Bridge by using Yarn:

yarn add @shopify/app-bridge

Usage

Set up your app

In the following example, you need to store shopOrigin during the authentication process and then retrieve it for the code to work properly. To learn more about this process, see Getting and storing the shop origin.

Import the library from the @shopify/app-bridge package and provide a configuration:

import createApp from '@shopify/app-bridge';

const app = createApp({
  apiKey: 'API key from Shopify Partner Dashboard',
  shopOrigin: shopOrigin,
});

Actions

Shopify App Bridge introduces the concept of actions. An action provides a way for applications and hosts to trigger events with a statically-typed payload.

To learn more about the supported actions, see the actions documentation.

App State

Once the app is set up, you can access additional details and the state of the app at any time by making async call app.getState():

app.getState().then((state: any) => {
  console.info('App State: %o', state);
});

You can also use a shorthand to retrieve nested properties by passing in a query when calling getState(query), for example:

app.getState('pos.user').then((user: any) => {
  console.log('POS User: %o', user);
});

Hooks

Shopify App Bridge can be extended with hooks, which run when actions are dispatched and updated. Hooks are middleware that can modify or cancel actions.

Development & Debugging

Shopify App Bridge is shipped with a development build, which provides detailed debugging information during development.

If you're consuming App Bridge from a CDN or using the UMD build, simply include the development version: umd/index.development.js instead of umd/index.js

When consumed as JS Modules, development/production build is dynamically selected based on the NODE_ENV variable. Development build is used when NODE_ENV=development.

Please note that the development build is not intended for production use, as the file size is significantly larger.
