Description

Monitoring your web app is one the many ways to prevent hackers from breaking your app. In this tutorial, we do this by creating an expressjs middleware that logs all information related to the received request and return response.

Goal

Capture all requests (request and response) that my express application handles.

Step by Step

  • initialize npm package
mkdir express-request-capture && cd express-request-capture
npm init -y
  • create index.js file
# this will be the entry/main file of our middleware
touch index.js
  • add content to index.js file
module.exports = require('./src/capture.js')
  • create the src folder
mkdir src
  • create a capture.js file inside src

  • put logic inside the capture.js file

  • publish to npm

npm login
npm publish
    1. use the middleware
