Configuration

Platformatic Remix is configured with a configuration file. It supports the use of environment variables as setting values with configuration placeholders.

It supports all the settings supported by Platformatic Vite, plus the following one:

• remix.outputDirectory: The subdirectory where production build is stored at when using wattpm build or plt build. The default is build.

note

Platformatic Remix uses this property instead of application.outputDirectory (which is ignored).

runtime

The runtime property allows you to embed runtime configuration directly in your application's configuration file. This is useful when you want to configure runtime-level settings specific to this application without needing a separate runtime configuration file.

See the runtime configuration documentation for details on each property.

Available properties

The following runtime properties can be configured at the application level:

• preload: Files to load before the application code.
• workers: Worker configuration for this application.
• logger: Logger configuration.
• server: Server configuration (hostname, port, HTTPS, HTTP/2).
• watch: Enable/disable file watching.
• health: Health check configuration.
• telemetry: OpenTelemetry configuration.
• undici: Undici HTTP client configuration.
• httpCache: HTTP caching configuration.
• metrics: Prometheus metrics configuration.
• gracefulShutdown: Shutdown timeout settings.
• startTimeout: Application start timeout.
• restartOnError: Restart behavior on errors.
• compileCache: Node.js compile cache settings.

Application-specific overrides

Within the runtime property, you can also use the application sub-property to configure application-specific settings that would normally be set in the runtime's applications array:

• workers: Worker count for this application.
• health: Health check settings for this application.
• env: Environment variables.
• envfile: Path to an .env file.
• sourceMaps: Enable source maps.
• preload: Files to preload.
• nodeOptions: Node.js options.
• execArgv: Arguments passed to worker threads.
• permissions: File system permissions.
• telemetry: Application-specific telemetry instrumentations.
• compileCache: Compile cache settings.

Example

The following example uses @platformatic/next, but the same configuration applies to other capabilities like @platformatic/node, @platformatic/astro, @platformatic/vite, and @platformatic/remix.

{
  "$schema": "https://schemas.platformatic.dev/@platformatic/next/3.31.0.json",
  "runtime": {
    "logger": {
      "level": "debug"
    },
    "workers": {
      "dynamic": true,
      "minimum": 1,
      "maximum": 4
    },
    "application": {
      "env": {
        "CUSTOM_VAR": "value"
      },
      "execArgv": ["--max-old-space-size=4096"]
    }
  }
}
