Function Serializer

Add a method of a controller as a response serializer.

Example

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

@Controller()
export default class MyController extends ControllerBase {
  @GET()
  async index(request: IHttpRequest, response: IHttpResponse) {
    // this will be serialized and send
    // by 'serializeResponse()' method (s. below)
    return {
       success: true,
       data: 'foo'
    }
  }

  @Serializer()  // mark that method as default serializer
                 // inside that controller
  async serializeResponse(result: any, request: IHttpRequest, response: IHttpResponse) {
    const jsonResponse = Buffer.from(JSON.stringify(result), 'utf8')

    response.writeHead(200, {
      'Content-Length': String(jsonResponse.length),
      'Content-Type': 'application/json; charset=UTF-8'
    });
    response.write(jsonResponse)
  }
}
