Adding Keystatic to a Remix project

☝️

This guide assumes you have an existing Remix project.

If you don't have an existing Remix project, you can create a new one with the following command:

npx create-remix@latest

Installing dependencies

Add Keystatic's core and remix packages:

npm install @keystatic/core @keystatic/remix

Creating a Keystatic config file

Create a file called keystatic.config.ts in the root of the project and add the following code to define both your storage type (local) and a single content collection (posts):

// keystatic.config.ts
import { config, fields, collection } from '@keystatic/core';

export default config({
  storage: {
    kind: 'local',
  },
  collections: {
    posts: collection({
      label: 'Posts',
      slugField: 'title',
      path: 'app/content/posts/*',
      format: { contentField: 'content' },
      schema: {
        title: fields.slug({ name: { label: 'Title' } }),
        content: fields.document({
          label: 'Content',
          formatting: true,
          dividers: true,
          links: true,
          images: true,
        }),
      },
    }),
  },
});

Keystatic is now configured to manage your content based on your schema.

Setting up the Keystatic Admin UI

Create an app/routes/keystatic.$.tsx file that will host all Admin UI routes:

// app/routes/keystatic.$.tsx
import { makePage } from '@keystatic/remix/ui';
import config from '../../keystatic.config';

export default makePage(config);

Next, create an app/routes/api.keystatic.$.tsx file that will handle API routes for Keystatic’s Admin UI:

// app/routes/api.keystatic.$.tsx
import type { ActionFunction, LoaderFunction } from '@remix-run/node';
import { handleLoader } from '@keystatic/remix/api';
import config from '../../keystatic.config';

export const loader: LoaderFunction = args => handleLoader({ config }, args);
export const action: ActionFunction = args => handleLoader({ config }, args);

Running Keystatic

You can now launch the Keystatic Admin UI. Start the Remix dev server:

npm run dev

Visit the /keystatic using localhost or 127.0.0.1 in your browser to see the Keystatic Admin UI running.

Creating a new post

☝️

In our Keystatic config file, we've set the path property for our posts collection to app/content/posts/*.

As a result, creating a new post from the Keystatic Admin UI should create a new content directory in the app directory, with the new post .mdoc file inside!

Go ahead — create a new post from the Admin UI, and hit save.

You will find your new post inside the app/content/posts directory:

app
└── content
    └── posts
        └── my-first-post.mdoc

Navigate to that file in your code editor and verify that you can see the Markdown content you entered. For example:

---
title: My First Post
---

This is my very first post. I am **super** excited.

Rendering Keystatic content

💡

Keystatic provides a Reader API to bring content to the front end. As it is a Node API it must be run server-side.

Displaying a collection list

The following example displays a list of each post title, with a link to an individual post page:

// app/routes/posts._index.tsx
import { createReader } from '@keystatic/core/reader'
import { Link, useLoaderData } from '@remix-run/react'
import { json } from '@remix-run/node'

import keystaticConfig from '../../keystatic.config'

export async function loader() {
  // 1. Create a reader
  const reader = createReader(process.cwd(), keystaticConfig)
  // 2. Read the "Posts" collection
  const posts = await reader.collections.posts.all()
  return json({ posts })
}

export default function Page() {
  const { posts } = useLoaderData<typeof loader>()

  return (
    <ul>
      {posts.map((post) => (
        <li key={post.slug}>
          <Link to={`/posts/${post.slug}`}>{post.entry.title}</Link>
        </li>
      ))}
    </ul>
  )
}

Displaying a single collection entry

To display content from an individual post, you can import and use Keystatic's <DocumentRenderer />:

// app/routes/posts.$slug.tsx
import { createReader } from '@keystatic/core/reader'
import { DocumentRenderer } from '@keystatic/core/renderer'
import { type LoaderFunctionArgs, json } from '@remix-run/node'
import { useLoaderData } from '@remix-run/react'

import keystaticConfig from '../../keystatic.config'

export async function loader({ params }: LoaderFunctionArgs) {
  const reader = createReader(process.cwd(), keystaticConfig)
  const slug = params.slug
  if (!slug) throw json('Not Found', { status: 404 })
  const post = await reader.collections.posts.read(
    slug, 
    // Retrieve the content data directly, instead
    // of getting an async `content()` function
    { resolveLinkedFiles: true }
  )
  if (!post) throw json('Not Found', { status: 404 })
  return json({ post })
}

export default function Post() {
  const { post } = useLoaderData<typeof loader>()
  return (
    <>
      <h1>{post.title}</h1>
      <DocumentRenderer document={post.content} />
    </>
  )
}

Deploying Keystatic + Remix

🚀

Coming soon!

You will also probably want to connect Keystatic to GitHub so you can manage content on the deployed instance of the project.
