Programmatic API

Using the @platformatic/runtime API, you can start Platformatic applications programmatically, bypassing the command line. This API facilitates interaction with various application types such as service, db, composer, and runtime, simplifying operations across different services.


buildServer function initializes a server based on a configuration object or file. It supports configurations for Platformatic Service, Platformatic DB, Platformatic Composer, and any other applications developed on top of Platformatic Service.

import { buildServer } from '@platformatic/runtime'

// Initialize the server using a configuration file
const app = await buildServer('path/to/platformatic.runtime.json')
const entrypointUrl = await app.start()

// Sample request to the server's entrypoint
const res = await fetch(entrypointUrl)
console.log(await res.json())

// Perform other operations

await app.close()

Custom Configuration

You can customize your server setup directly within your code by specifying the configuration details:

import { buildServer } from '@platformatic/runtime'

const config = {
// $schema: '',
// $schema: '',
// $schema: '',
// $schema: ''
const app = await buildServer(config)

await app.start()


The loadConfig function reads and parses a configuration file for any Platformatic application. It can automatically detect the type of application or accept explicit instructions.

import { loadConfig } from '@platformatic/runtime'

// Read the configuration and automatically detect the application type.
const config = await loadConfig({}, ['-c', '/path/to/platformatic.config.json'])

// Read the config based on command line arguments and provide default configuration if needed
const config = await loadConfig(
['-c', '/path/to/platformatic.config.json']

// Specify a default config
const config = await loadConfig(
['-c', '/path/to/platformatic.config.json'],
{ key: 'value' }


The start function loads a configuration, builds and starts a server but does not return the server instance. This function is best suited for scenarios where no further interaction with the server is necessary after launch.

import { start } from '@platformatic/runtime'

await start(['-c', '/path/to/platformatic.config.json])


The startCommand function is similar to start. However, if an exception occurs, startCommand logs the error and exits the process. This is different from start, which throws the exception.

import { startCommand } from '@platformatic/runtime'

await startCommand(['-c', '/path/to/platformatic.config.json])
