http-deceiver

What is http-deceiver?

The http-deceiver npm package is designed to manipulate HTTP requests and responses. It allows developers to intercept, modify, and create custom behaviors for HTTP traffic, which is particularly useful in testing and development environments where simulating various network conditions and responses is necessary.

What are http-deceiver's main functionalities?

Intercept and modify HTTP requests

This feature allows you to intercept HTTP requests and modify properties such as the URL before the server processes them. In the provided code, the request URL is changed to '/modified-path', and a custom response is sent back.

const httpDeceiver = require('http-deceiver');
const http = require('http');

const server = http.createServer((req, res) => {
  httpDeceiver.deceive(req, res, (req, res) => {
    req.url = '/modified-path';
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Request was modified');
  });
});

server.listen(3000);

Simulate server responses

This feature is useful for simulating different server responses under various conditions. In this example, a 503 Service Unavailable response is simulated regardless of the actual server state or the incoming request.

const httpDeceiver = require('http-deceiver');
const http = require('http');

const server = http.createServer((req, res) => {
  httpDeceiver.deceive(req, res, (req, res) => {
    res.writeHead(503, {'Content-Type': 'text/plain'});
    res.end('Service Unavailable');
  });
});

server.listen(3000);

Other packages similar to http-deceiver

nock

Nock is a powerful HTTP server mocking and expectations library for Node.js. It allows you to control HTTP requests and responses with a high level of granularity. Compared to http-deceiver, nock provides a more comprehensive API for defining precise request and response behaviors, making it ideal for complex testing scenarios.

sinon

Sinon provides standalone test spies, stubs, and mocks for JavaScript. While it is not limited to HTTP, it can be used in conjunction with other libraries to mock HTTP interactions. Sinon is generally more flexible than http-deceiver as it can handle a wider range of testing needs beyond just HTTP.
