If you're used to writing serverless functions in individual files, but need to write them on an express.js app, this package makes that easy.

// To keep this package extremely lightweight, setup a mock express.js app:
const blank = {
  status: (statusCode) => {
    return { send: (message) => {} }
  },
  sendStatus: (statusCode) => {
    return statusCode;
  }
}

const mockExpressRoute = function(url, ...functions){
  console.log(`App has registered: ${url}`)

  // Simulate each function being called once.
  functions.forEach(fn => fn(blank, blank, () => { console.log("Going to next") }))
}

const app = {
  put:    mockExpressRoute,
  post:   mockExpressRoute,
  get:    mockExpressRoute,
  delete: mockExpressRoute,
  all:    mockExpressRoute,
}

require('../index')(app, {
  path: './test/functions',
  defaultMethod: 'post',
  verbose: true,
  autoTryCatch: true,
  middleware: [
    {
      match: /index\.js$/i,
      method: 'post',
      pre: [
        function(req, res, next){
          console.log("Pre middleware 1!")
          next()
        },
        function(req, res, next){
          console.log("Pre middleware 2!")
          next()
        }
      ],
      post: [
        function(req, res, next){
          console.log("Post middleware 3!")
          next()
        }
      ]
    }
  ]
})
