Function Import

Imports a value into a property and sets up a getter for this.

Example

import createServer, { Controller, ControllerBase, GET, IHttpRequest, IHttpResponse, Import } from '@egomobile/http-server'

// setup controller and define the
// value keys to import

@Controller()
export default class MyController extends ControllerBase {
  @Import()  // s. [1]
  public foo!: string

  @Import('currentTime')  // s. [2]
  public now!: Date

  @GET()
  async index(request: IHttpRequest, response: IHttpResponse) {
    response.write(this.foo + ': ' + this.now)
  }
}

// setup server with import values ...

const app = createServer()

// setup controller
// with import values
app.controllers(__dirname, {
  // [1] no function => static value for MyController.foo property
  foo: 'bar',

  // [2] function => dynamic value for MyController.now property
  currentTime: () => new Date(),
})

app.listen()
