You can create a React-based settings page for your app on the latest version (2025.2) of the developer platform, that users who install your app can navigate to and customize for their account. This guide walks you through how to build a settings component, using React, which replaces the previous settings experience. If you deploy your new settings component, users who install your app going forward will immediately see your new settings extension instead of any previously built settings page. Before you begin, follow the quickstart guide to create your first app on the latest version of the developer platform.
Please note: if you previously created a settings page for your legacy app, you’ll need to refactor your settings experience using the new configuration options outlined in this guide. It’s recommended that you note all of the interface elements in the current production version of your app before you start configuring your new settings component on the latest version of the developer platform. Once you move to the new settings component for your app, you’ll lose access to the previous WYSIWYG configuration UI you previously used.

Prerequisites

​
Create an app settings page

1

Add an app settings component to your project

To add a settings page component to an existing app, use the terminal to navigate into your local project directory, then run the following command:
hs project add
Then, when prompted to select a component to add, select Settings.Screenshot of the terminal prompt for selecting the type of component to addA new settings/ directory will be created in the project’s src/app/ directory. The settings/ directory will contain:
  • A JSON configuration file (*-hsmeta.json)
  • A React component file (.jsx)
  • A package.json file
myProject
└── src/
    └── app/
        └── settings/
            ├── new-settings-page-hsmeta.json
            ├── NewSettingsPage.tsx
            └── package.json

{
  "uid": "settings_extension",
  "type": "settings",
  "config": {
    "entrypoint": "/app/settings/NewSettingsPage.tsx"
  }
}

Upload to HubSpot

To upload your settings page to HubSpot:
  • Run hs project install-deps from within your local project directory to install necessary dependencies. This will create a package-lock.json file, which will speed up the build of the uploaded settings extension, as well as ensure that any dependencies in your local development environment and production match.
  • Then, run hs project upload.
  • After the project finishes deploying, open the project in HubSpot by running hs project open. Alternatively, in HubSpot you can navigate to Development > Projects, then click the name of your project.
  • Your settings component should now be listed on the details page.

​
View the app settings page in HubSpot

To verify the settings component is working correctly:
  • In the HubSpot account where you’ve installed the app, click the Marketplace icon, then click Connected apps.
Navigate to connected apps in developer test account
  • Click the My apps tab to view a list of the account’s currently installed apps.
  • Click the name of your app, which will redirect you to your app’s overview page.
  • On the overview page, click the Settings tab.

You can now continue to build out your app’s settings page as needed. Similar to building app cards, you’ll use the UI extensions SDK to add functionality and visual elements to your settings page. Note that all the existing limitations around building UI extensions apply to building a settings page.
  • Use hubspot.fetch to leverage your backend to save and retrieve settings. Learn more about using this approach in the legacy documentation.
  • Check out the reference documentation on standard components for how to use React components when building your extension, or use the component in the Figma Design Kit.
  • Use the hs project dev command to iteratively build out your settings page and preview your changes locally.
The local development server will only pick up changes saved to the front-end React file. If you update the *-hsmeta.json or package.json files, you’ll need to stop the server, upload your changes, then start the server again.

Component best practices

The sections below outline several best practices to keep in mind as you build out the settings experience for your app.

​
Organizing content

If you have enough content in your settings extension to warrant the need to separate and organize all of the user’s settings data, you should consider using the Panel, Modal, Accordion, and Tabs components accordingly. Consider how you want to present and arrange your settings and the corresponding data that should be fetched for each component.

​
Tabs

If you’re using Tabs, use the default tab variant. The settings extension is already contained within an enclosed variant tab, and a second layer of enclosed tabs will visually clash with the design.

The following snippet outlines how to structure your tabs. 
<Tabs>
  <Tab title="First Tab">
    <Text>Here is the content of the first tab.</Text>
  </Tab>
  <Tab title="Second Tab">
    <Text>This is where the content of the second tab goes.</Text>
  </Tab>
</Tabs>
