rhttp_node v0.1.4

RHTTP-node

RHTTP NodeJS interface

Usage

First create RHTTP server and pass redis host and port to it

const server = new RHTTPServer("127.0.0.1", 6379);

The RHTTPServer class have a function for every HTTP method. Each method function has two parameters:

1. Path: It's the path of endpoint
2. Callback: It's callback function to handling requests

server.get('/', (req, res) => {
  const response_data = {
    msg: 'Hello User!',
  };
  return res.status(200).contentType('application/json').send(JSON.stringify(response_data));
});

The Callback parameter is a function with two parameters:

• request: Contains HTTP request data such as body, query params, etc.
• response: An instance of Response class that you can modify and send response to user using it.

Response methods:

• status: Sets HTTP status code and status message
  • res.status(200)
• contentType: Sets HTTP content type
  • res.contentType("application/json")
• header: Append HTTP header to response
  • res.header({"X-Custom-Header": "Header Value"})
• send: Finalizes response progress and make HTTP response string
  • res.status(200).contentType('application/json').send(JSON.stringify(response_data))

Note You need to return send() method result to callback function to continue progress.

At the end server needs to listen to Redis for receiving incoming requests:

server.listen((err) => {
  if (err) {
    console.error(err);
  } else {
    console.info('Server is ready');
  }
});
