Question

What is the best way to interact with Redis without using any external modules?

I am curious about the communication process between the node redis wrapper and the RESP (REdis Serialization Protocol) database.

Here is a simple example:

const redis = function(uri) {
  this.client = '' // How do we establish a connection with the Redis URI redis://localhost:6379?
}

redis.prototype.set = (key, value, callback) => {
  // How can we communicate with Redis to set a specific value?
}

javascript node.js npm redis

The RESP, or Redis Serialization Protocol, is a straightforward text-based protocol that operates over a TCP connection.

In Node.js, you can establish TCP connections using the built-in net module and its Socket class. This allows for seamless communication with network services like Redis.

Here's a basic example in Node.js utilizing the net module:

var net = require('net');

const redisClient = function(uri) {
  var host = getHostFromUri(uri), port = getPortFromUri(uri);
  this.socket = new net.Socket();
  this.socket.connect(port, host, function() { ... });
  this.socket.on('data', function(msg) {
    if(this.responseHandler) this.responseHandler(msg);
  });
}

redisClient.prototype.set = function(key, value, callback) {
  // Assuming successful connection
  this.socket.write("SET " + key + " " + value + "\r\n");
  this.responseHandler = callback;
}
