import Serverlessizer from '@satheler/s12r'

let server: ServerContract

async function bootstrapServer () {
  const ignitor = new Ignitor(__dirname)
  const httpServer = ignitor.httpServer()

  httpServer.application.setup()
  httpServer.application.registerProviders()
  httpServer.application.requirePreloads()
  await httpServer.application.bootProviders()

  const server = httpServer.application.container.use('Adonis/Core/Server')
  server.optimize()

  return server
}

export const handle = async (...args: any[]) => {
  if(!server) {
    server = await bootstrapServer()
  }

  const { request, response } = Serverlessizer(args)
  return server.handle(request, response)
}

Express (Coming soon)

Hapi (Coming soon)

LoopBack (Coming soon)

⚡️ Serverless Framework

The Serverless Framework uses new event-driven compute services, like AWS Lambda, Google Cloud Functions, and more. It's a command-line tool, providing scaffolding, workflow automation and best practices for developing and deploying your serverless architecture.

Below has a example of serverless configuration with typescript. The project output in tsconfig.json is set as build.
