Response object

The response object helps you control the headers and data sent to the client. List of methods and properties:

  • response.status(status: number)
    Sets the HTTP status with which the response will be sent.

  • response.set(field: string | object [, value: string])
    Controls response headers. The first argument can be an object, and then the headers corresponding to the keys and values will be passed, or it can be a string. In this case, the second argument will be the header value.

      'Content-Type': 'application/json'
    // or
    response.set('Content-Type', 'application/json');
  • response.type(type: string)
    Sets the Content-Type header of the response

  • response.send(data: string|number|object|array)
    Passing data to the response body. If an array or object is passed, the data will be converted to a string using JSON.stringify.

  • response.redirect(url: string)
    301 redirect to url

  • response.sendFile(path: string)
    Sends the file at path to the client. The MIME type of the response is automatically set.
