Most of Shopify App Bridge's functionality relies on actions. See the Actions section to learn more about how to use these.

Anchor to Initialization methodsInitialization methods

Anchor to [object Object]createApp(config)

Returns an app object. Used to initialize your app instance.

The config object should contain the following keys:

KeyTypeDescription

hoststringThe base64-encoded origin/domain of the Shopify shop, which is provided by Shopify as a query parameter on the initial load of your app in the Shopify Admin. The host is set dynamically and should be stored in the session from the initial load.
Note

In the following example, config is a valid App Bridge configuration object. Learn more about configuring App Bridge.

import createApp from '@shopify/app-bridge';
const app = createApp(config);
var AppBridge = window['app-bridge'];
var createApp = AppBridge.createApp;
const app = createApp(config);
