What are Portals?

You can customize your app by modifying a Shopgate theme with portals. You use a portal to add, replace, or remove React components from a theme using an extension. Use portals to customize the existing theme without having to fork or build your own. However, for extensive customizations, we recommend creating your own theme.

Portal Types: Parents and Siblings

There are two types of portals: parents and siblings. You use a parent portal to wrap around and replace an existing React component. You use a sibling portal to inject new components above or below an existing React component.

Portal Names

portals have unique names, and portal names use the following naming convention: <feature>.<content>.<position (optional)>. Sibling names always include a position suffix in their names.

Parent portal name example: PRODUCT-ITEM.NAME

Sibling portal name example: PRODUCT-ITEM.NAME.AFTER

Refer to the Portals Reference for a list of available portals.

How to Add a Component using a Portal

  1. Open the extension-config.json file at the root of your extension.
  2. Add the following code to the components array.
  3. Make sure that your extension is attached and the SDK is running.


    "id": "MyComponent",
    "path": "frontend/MyComponent/index.jsx",
    "target": "product-item.name.before",
    "type": "portals"
Code Definition
id Unique id for this portal component. Must be unique within this extension.
path Relative path to the component that renders inside the portal. Path must include the file extension, and the file it references must export a valid React component.
target Name of the portal to use.
type Must be portals.
  1. Verify that your component, MyComponent, appears at the position of the product-item.name.before portal.

How to Create a New Page with Portals

To create a new page you can use the app.routes portal. This portal gives you a View component as a prop which you can use to render the page. To do this you must create a new component in your extension:

import React from 'react';
import PropTypes from 'prop-types';
import { Route } from '@shopgate/engage/components';

class MyPageComponent extends React.Component {
  render() {
    const { View } = this.props;
    return (
        <div>Hello, I'm a page.</div>

const MyRoute = props => (

export default MyRoute;
  1. Go to /myroutepath to see the rendered MyPageComponent.
