Testing Package 🧪

We’ve shipped a new package called @keystone-next/testing to help you write tests for your GraphQL API!

Check out the guide on the Keystone website for more details.

Document Field Example ✍️

We have a new example project for the document field which covers the basic use case of configuring the toolbar, rendering the document field in a front end, and providing custom renderers for the built in data.

Another example showing advanced use cases is in-progress and will be available soon!

Error Messages ❗

GraphQL error messages are far more helpful when running queries. You will now get relevant error messages instead of getting Cannot assign to read only property 'path' of object '#<Object>'" back.

Thanks @tjbp for contributing this fix!

Improved Types for KeystoneContext 📜

⚠️ We've tweaked lists and db.lists APIs on KeystoneContext to have improved types. If you're using the generated KeystoneListsTypeInfo type like this:

const lists: KeystoneListsAPI<KeystoneListsTypeInfo> = context.lists;

You will have to change it to use as like this:

const lists = context.lists as KeystoneListsAPI<KeystoneListsTypeInfo>;

UI Accessibility 🏷

Another set of accessibility improvements in the Admin UI in this release including assorted quality of life and screen reader improvements to Filter pills and dialogs, as well as labels and descriptions.

Prisma update ⬆️

We've updated our Prisma dependencies to 2.25.0, check out the Prisma releases page for more information.
