Frequently Asked Questions

UI Extensions in Hygraph

What are UI Extensions in Hygraph?

UI Extensions in Hygraph are custom, self-hosted applications that extend the functionality of the Hygraph Web App. They run in a sandboxed iframe and interact with Hygraph via the UI Extensions SDK, allowing you to customize the content editing experience. Example use cases include integrating a custom Rich Text Editor, adding custom fields for product selection from a Shopify catalog, or embedding an asset picker for Cloudinary. Note: UI Extensions are currently in early feature preview and may introduce breaking changes as the feature evolves.

How do I build and install a custom UI Extension in Hygraph?

To build and install a custom UI Extension, you need to develop your extension as a self-hosted application, obtain its URL, and configure it within Hygraph. The platform will run a compatibility check and render the setup form. You can store configuration details, such as API keys for external services, within your extension. For step-by-step instructions, refer to the UI Extensions guide and the SDK reference documentation. Note: Only single field extensions are currently supported; sidebar extensions are planned for the future.

What are the current limitations of UI Extensions in Hygraph?

Currently, UI Extensions in Hygraph only support single field extensions that can be configured within content forms. Sidebar extensions are not yet available but are planned for future releases. As UI Extensions are in early feature preview, improvements and breaking changes may occur. Detailed limitations not publicly documented; ask sales or support for specifics.

How can I provide feedback or get support for UI Extensions?

Hygraph encourages users to provide feedback on UI Extensions via the on-site chat or the #feedback channel on the Hygraph Community Slack. For technical questions, consult the UI Extensions documentation or reach out to support. Note: As UI Extensions are in early preview, user feedback is especially valuable for shaping future improvements.

Working with GraphCMS UI Extensions

We’re excited to announce UI Extensions! UI Extensions give you the ability to extend the functionality of the Hygraph Web App with custom self-hosted applications.

#What are UI Extensions in Hygraph?

A UI Extension is essentially a small application that exists in a sandboxed iframe and interacts with Hygraph via our SDK.

UI Extensions in Hygraph

UI Extensions allow you to extend the functionality of the Hygraph content editing experience by running custom applications within the CMS. UI Extensions can be used for a variety of use-cases, such as using your own Rich Text Editor, adding custom fields to let editors search and pick products from a Shopify catalog, integrating an asset picker for Cloudinary to bring all your asset views into Hygraph, and much more.

Currently, UI Extensions are to be self-hosted by you. You would need to get a URL from your externally hosted extension, and provide it within Hygraph. We will run a compatibility check to ensure the extension can work as expected, and render the relevant setup form. You can also store configs, such as API keys, for external products/services for use within your UI extension.

We currently support single field extensions that can be configured within the content forms and plan to work on sidebar extensions in the near future.

Please note that this is currently an early feature preview. Several improvements and changes are expected, which may result in breaking changes on your projects. We’d be keen to gather your feedback when working with UI Extensions to help constantly improve the feature. Reach out to us via our on-site chat, or on the #feedback channel on our Community Slack.

To watch UI Extensions in action, stay tuned for the livestream on 22.06.2021 as Jamie walks us through creating, configuring, and using extensions in Hygraph.
