Prerequisites

• You have already created an Nx workspace
• Node 20+
• Docker

Optional Nx installed globally

The commands in this readme assume that Nx is installed globally.

nx [...]

If you prefer not to, you can use your preferred package manager to prefix the commands like this example for npm.

npx nx [...]
# or
npm run nx [...]

Installation

!IMPORTANT This documentation is aimed for a Payload v3 setup.

To install Payload v2 you should use plugin version 1.x.

Though it's possible to have applications using Payload v2 and v3 in the same workspace, it's not recommended. Payload v2 supports React 18 and v3 has moved to React 19. But with individual package.json files for the applications and some Dockerfiles sed magic it's possible to make it work.

Add Payload plugin to an existing workspace

nx add @cdwr/nx-payload

Inferred tasks

The plugin automatically generates Payload tasks for projects that has a payload.config.ts file somewhere in the project. The default location is in {projectRoot}/src.

• gen
• payload
• payload-graphql

!TIP A couple of targets to improve Developer Experience (DX) are also generated:

• dx:mongodb
• dx:postgres
• dx:start
• dx:stop

Configuration

Plugin configuration is added to nx.json by default.

{
  "plugins": [
    {
      "plugin": "@cdwr/nx-payload/plugin",
      "options": {
        "generateTargetName": "gen",
        "payloadTargetName": "payload",
        "payloadGraphqlTargetName": "payload-graphql",
        "dxMongodbTargetName": "dx:mongodb",
        "dxPostgresTargetName": "dx:postgres",
        "dxStartTargetName": "dx:start",
        "dxStopTargetName": "dx:stop"
      }
    }
  ]
}

Opt out from automatic inferrence

To disable automatic targets generation and write explicit targets to project.json, use one of these two options:

• Set useInferencePlugins in nx.json to false
• Set environment variable NX_ADD_PLUGINS to false

Usage

Generate a Payload application

nx g @cdwr/nx-payload:app

MongoDB, Postgres, Supabase or SQLite?

Payload has official support for database adapters MongoDB, Postgres and SQLite.

!TIP

Supabase is set up using the Postgres adapter

Changing the adapter for a generated application must be done manually in payload.config.ts.

!IMPORTANT We don't want to infer opinionated complexity into the Payload configuration. A new application is just a working template that you will customize and evolve to your needs.

Fortunately, changing the database is straightforward, and only a few parts need to be replaced.

// MongoDB @ payload.config.ts

import { mongooseAdapter } from '@payloadcms/db-mongodb';

export default buildConfig({
  db: mongooseAdapter({
    url: process.env.DATABASE_URI
  })
});

// Postgres/Supabase @ payload.config.ts

import { postgresAdapter } from '@payloadcms/db-postgres';

export default buildConfig({
  db: postgresAdapter({
    pool: {
      connectionString: process.env.DATABASE_URI
    }
  })
});

!TIP More information can be found on the official Payload Database page.

Developer Experience (DX)

The application come with a set of opinionatedtargets to improve developer experience. These targets are prefixed with dx: are optional to use.

!TIP Display all the targets with extensive details for an application

nx show project [app-name]

Start Payload and database in Docker

This is the quickest way to get Payload up and running in no time.

Using docker compose, both MongoDB and Postgres are started in each container, as well as the Payload application.

nx dx:start [app-name]

Open your browser and navigate to http://localhost:3000 to setup your first user.

Stop

Shutdown database and Payload containers.

nx dx:stop [app-name]

Database volumes are persistent, hence all data is available on next launch.

Start a local database instance of choice

You can also start the preferred database first, to be properly initialized before Payload is served.

MongoDB

Run MongoDB in Docker

nx dx:mongodb [app-name]

Postgres

Run Postgres in Docker

nx dx:postgres [app-name]

Supabase

Supabase has its own powerful toolset running local dev with CLI

npx supabase init

npx supabase start

Edit DATABASE_URI in .env.local when needed.

Serve Payload application in development mode

Payload application is served in watch mode.

!NOTE The configured database must have been started, see local database

nx dev [app-name]

Open your browser and navigate to http://localhost:3000.

Run Payload commands

All commands available from Payload can be used for the application via targets payload and payload-graphql.

nx payload [app-name] [payload-command]

This is specially useful for managing migrations, for example to check database migration status.

nx payload [app-name] migrate:status

Generate TypeScript types and GraphQL schema

To provide a better developer experience for client development, the plugin can generate TypeScript types and GraphQL schema files from the Payload configuration.

!IMPORTANT GraphQL schema will not be generated if graphQL.disable is set to true in payload.config.ts

nx gen [app-name]

The generated files are written to the generated folder. The types can be distributed to the client developer manually or saved to a shared library in the monorepo.

!NOTE The gen target is actually an alias for the following commands.

nx payload [app-name] generate:types
nx payload-graphql [app-name] generate:schema

Troubleshooting

I can't get Payload to start properly with Postgres in prod mode

Using Postgres in development mode enables automatic database synchronization with the Payload collections. But when starting in production mode it's turned off and the database is expected to have been setup with the collections. So when Postgres is started without a database, Payload will encounter errors.

The solution is to have an initial migration ready for Payload to load during startup.

Create a migration

Make sure Postgres is running. Start Payload in development mode to setup your database with the collections.

nx dev [app-name]

Create a migration.

nx payload [app-name] migrate:create

Now Payload will run migrations automatically when starting in production mode.

!IMPORTANT The property db.prodMigrations in payload.config.ts must be set for this to work.

You don't have an Nx workspace?

Just use the plugin sibling to get started from scratch.

See create-nx-payload for more details.

Plugin Generators

init (internal)

Initialize the @cdwr/nx-payload plugin.

No options.

application

Alias: app

Generate a Payload application powered by Next.js.

💡 name can also be provided as the first argument (used in the examples in this readme)

Migrate from Payload v2 to v3

Most of the setup is the same, but there are some breaking changes that you need to be aware of. Besides that, follow the type errors to update the code.

Preparation

• Nx must have version 20.4.2 or higher.
• React must have version 19.0.0 or higher.
• Install @nx/next plugin.
• Install @nx/eslint plugin.
  • Convert to flat file configuration.
  • Use eslint.config.mjs files.
• Install graphql package.

Packages

Payload now use a common version for its packages.

Install new packages:

• @payloadcms/next
• @payloadcms/graphql (dev dependency)

Update to latest:

• payload
• @payloadcms/db-mongodb
• @payloadcms/db-postgres
• @payloadcms/richtext-lexical

Remove deprecated packages:

• @payloadcms/bundler-webpack
• @payloadcms/richtext-slate
• @nx/express (used elsewhere?)

Versions Compatibility

Later versions of Nx or Payload might work as well, but the versions below have been used during tests.
