• Powerful Admin UI for content management out of the box
• Supports various database backends, including MongoDB and PostgreSQL

Cons

• Steeper learning curve compared to some simpler CMS solutions

• Limited themes and templates available for quick setup

Code Examples

1. Defining a Keystone schema:

import { list } from '@keystone-6/core';
import { text, relationship } from '@keystone-6/core/fields';

export const lists = {
  User: list({
    fields: {
      name: text({ validation: { isRequired: true } }),
      email: text({ isUnique: true, validation: { isRequired: true } }),
      posts: relationship({ ref: 'Post.author', many: true }),
    },
  }),
  Post: list({
    fields: {
      title: text(),
      content: text({ ui: { displayMode: 'textarea' } }),
      author: relationship({ ref: 'User.posts' }),
    },
  }),
};

2. Querying data using the GraphQL API:

query {
  users {
    name
    email
    posts {
      title
    }
  }
}

3. Customizing the Admin UI:

import { config } from '@keystone-6/core';

export default config({
  ui: {
    isAccessAllowed: (context) => !!context.session?.data,
  },
  // ... other configuration options
});
