Function HEAD

Add a controller method to handle a HEAD request.

Example

// index.ts

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

@Controller()
export default class IndexController extends ControllerBase {
  // can be accessed with a HEAD request
  // by using route /
  @HEAD()
  async index(request: IHttpRequest, response: IHttpResponse) {
    response.writeHead(200, {
      'x-ego-header1': '(root): ' + new Date()
    })
  }

  // can be accessed with a HEAD request
  // by using route /foo
  @HEAD()
  async foo(request: IHttpRequest, response: IHttpResponse) {
    response.writeHead(200, {
      'x-ego-header1': 'foo: ' + new Date()
    })
  }

  // can be accessed with a HEAD request
  // by using route /baz
  @HEAD('/baz')
  async foo(request: IHttpRequest, response: IHttpResponse) {
    response.writeHead(200, {
      'x-ego-header1': 'baz: ' + new Date()
    })
  }
}
