This project demonstrates a Posts list where a particular field is always required to be sent in a GraphQL request; this can useful for optimistic locking and versioning.

To run this project, clone the Keystone repository locally, run pnpm install at the root of this repository, then navigate to this directory and run:

pnpm dev

This will start the Admin UI at localhost:3000. You can use the Admin UI to create items in your database.

You can also access a GraphQL Playground at localhost:3000/api/graphql, which allows you to directly run GraphQL queries and mutations.

Congratulations, you're now up and running with Keystone! 🚀

This example includes sample data. To add it to your database:

1. Ensure you’ve initialised your project with pnpm dev at least once.
2. Run pnpm seed-data. This will populate your database with sample content.
3. Run pnpm dev again to startup Admin UI with sample data in place.
