Generates a Platformatic app programmatically.

The base class BaseGenerator is basically a file writer with some default behaviours.

It should be instantiated with an options object having this properties

• type: "db" | "service" | "composer"
• logger: A pino-like logger object. If not provided a fake logger with no output will be used
• questions: An array of custom questions object to provide to inquirer. Default to []

The setConfig({...}) function should be called to set the config generator. BaseGenerator supports the bare minumium set of options which are common to all types of apps

• targetDirectory Where in the local filesystem the app will be created
• port: The port where the app should listen
• hostname: The hostname where the app should listen
• plugin: Whether to create or not a sample plugin file structure
• typescript: true|false
• initGitRepository: Inits the git repository
• dependencies: A key value object to add dependencies in package.json file
• devDependencies: A key value object to add dev-dependencies in package.json file
• staticWorkspaceGitHubActions: Creates the GitHub action to deploy in a static workspace in Platformatic Cloud
• dynamicWorkspaceGitHubActions: Creates the GitHub action to deploy in a dynamic workspace in Platformatic Cloud
• env: A key/value object that will be automatically appended to the generated .env file

This is the simplest example to create a Platformatic Service app into /path/to/app

const { BaseGenerator } = require('@platformatic/generators')

async function main() {
  const gen = new BaseGenerator({
    type: 'service'    
  })
  gen.setConfig({
    targetDirectory: '/path/to/app'
  })
  await gen.run()
}

main()

The run() function will call the prepare() function which prepare all files in memory, which will be written by the writeFiles() function.

In order to customize the behavior of a subclass there are some functions that may be implemented

Returns an object that will be serialized with JSON.stringify method. It will be saved in the platformatic.${TYPE}.json file

Called from prepare function. You have already access to the current fastify version (this.fastifyVersion) and platformatic version (this.platformaticVersion)

Called at the end of prepare function body
