Parsing HTTP Requests

This code sample demonstrates how to use http-parser-js to parse an HTTP request. The parser object is created with the type HTTPParser.REQUEST, and callback functions are assigned to handle headers, body, and the completion of the message.

const httpParser = require('http-parser-js').HTTPParser;
const parser = new httpParser(httpParser.REQUEST);

parser[httpParser.kOnHeadersComplete] = function(headers, url) {
  // Use headers and url
};

parser[httpParser.kOnBody] = function(body) {
  // Use body
};

parser[httpParser.kOnMessageComplete] = function() {
  // Message is complete
};

// Simulate receiving data
const data = Buffer.from('GET / HTTP/1.1\r\nHost: example.com\r\n\r\n');
parser.execute(data);

Parsing HTTP Responses

This code sample shows how to parse an HTTP response using http-parser-js. The parser object is created with the type HTTPParser.RESPONSE, and callback functions are set up to process headers, body, and the end of the message.

const httpParser = require('http-parser-js').HTTPParser;
const parser = new httpParser(httpParser.RESPONSE);

parser[httpParser.kOnHeadersComplete] = function(headers, statusCode) {
  // Use headers and statusCode
};

parser[httpParser.kOnBody] = function(body) {
  // Use body
};

parser[httpParser.kOnMessageComplete] = function() {
  // Message is complete
};

// Simulate receiving data
const data = Buffer.from('HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\n\r\nHello World');
parser.execute(data);
