cyber-express-logger

A simple and colourful request logger for Express

Installation

Just use npm:

npm i cyber-express-logger

Usage

The module exports a single, default function.

Default function logger(opts?):

• Object opts:
  • Callback getIP(req):string
    Returns the client's IP address given the request object. By default, IPs will be checked for in the cf-connecting-ip header, then the x-forwarded-for header. If neither of those exist, we'll fall back to req.socket.remoteAddress.

Example

// Require modules
const express = require('express');
const logger = require('cyber-express-logger');

// Create express server
const srv = express();

// Set up logger
// Make sure this appears before any other request handlers
srv.use(logger({
    // Get the client's IP from a custom header
    getIP: req => req.header['my-ip-header']
}));

// ... Your request handlers ...

// Listen
const port = 8080;
srv.listen(port, () => console.log(`Listening on ${port}`));
