A First Look at KeystoneJS

All of this project's code can be found in the First Look monorepo on my GitHub.

Introduction

KeystoneJS is a CMS for developers that provides a GraphQL API & Management UI for content and data based on your schema. In this tutorial we will use create-keystone-app to scaffold a basic blog dashboard with users. In a future part we will deploy this project.

Create Keystone App

create-keystone-app is a CLI app for getting started with Keystone. It will generate a couple of files for you and install all the dependencies you need to run the Admin UI and start using the GraphQL API.

yarn create keystone-app

success Installed "create-keystone-app@4.0.12" with binaries:
      - create-keystone-app

ℹ️ You're about to generate a project using Keystone
Next packages. If you'd like to use Keystone 5, please
use `create-keystone-5-app` instead. Learn more about
the changes between Keystone 5 and Keystone Next on
our website.

https://next.keystonejs.com/guides/keystone-5-vs-keystone-next​

Give your project a name. Mine will be called ajcwebdev-keystone.

✔ What directory should create-keystone-app generate your app into? · ajcwebdev-keystone

You will need a database URL. If you want one fast you can use Railway, Supabase, Fly, or any of the other couple dozen "spin up Postgres in 30 seconds" services out there. I'll be using Railway.

You can follow the first half of this guide to see how to spin up the database. The only important difference is when you copy your connection string from Railway, change the first part from postgresql:// to postgres://.

Your connection string will look like this with a password instead of xxxx:

✔ What database url should we use? · postgres://postgres:xxxx@containers-us-west-3.railway.app:6787/railway

This will create the app and provide further instructions.

🎉  Keystone created a starter project in: ajcwebdev-keystone

To launch your app, run:

  - cd ajcwebdev-keystone
  - yarn dev

Next steps:

  - Edit ajcwebdev-keystone/keystone.ts to customize your app.
  - Open the Admin UI - ​http://localhost:3000​
  - Read the docs - ​https://next.keystonejs.com​
  - Star Keystone on GitHub - https://github.com/keystonejs/keystone​

Develop Keystone App Locally

Run yarn dev to start your local development server.

cd ajcwebdev-keystone
yarn dev

This will run keystone-next dev.

👋 Admin UI and GraphQL API ready

Open localhost:3000.

Create a user

You are then asked if you want to sign up for the KeystoneJS newsletter. Bold move!!!

After you decide whether to reward such brash behavior you will be taken to the Keystone dashboard where you can view your users and posts.

You will see the user you initially created.

Create a Post

You will see that there are no posts yet. What ever shall we do?

After clicking "Create Post" you will be able to create a post.

Write a post. Make it a masterpiece.

Look back at your database to make sure it didn't explode.

Query your GraphQL API

Open localhost:3000/api/graphql and run the following posts query.

query {
  posts {
    title
  }
}

Deploy Keystone App

Turns out deploying a Keystone app is kind of complicated unless you follow a separate guide called How to embed Keystone + SQLite in a Next.js app.
