I would like to create a middleware using morgan, i tryed to export the middleware function, then require in app.js. I don't kown why this is not working
Middleware:
const morgan = require('morgan');
const rfs = require("rotating-file-stream");
const rfsStream = rfs.createStream("logs/log.txt", {
size: '10M', // rotate every 10 MegaBytes written
interval: '1d', // rotate daily
compress: 'gzip' // compress rotated files
})
function logger(req, res, next){
morgan('tiny', {
stream: rfsStream
})
next();
}
module.exports.logger = logger;
App:
const express = require('express');
const app = express();
const PORT = 4000;
const { logger } = require('./middlewares/logger');
app.get('/', logger, (req, res) => {
res.send('Hello World!')
});
app.listen(PORT, () => {
console.log(`app running on port: ${PORT}`);
});
Morgan itself is a middleware. That means that you should pass it req
, res
and next
.
HTTP request logger middleware for node.js
So, try to change your Middleware
file like this:
const morgan = require('morgan');
const rfs = require("rotating-file-stream");
const rfsStream = rfs.createStream("logs/log.txt", {
size: '10M', // rotate every 10 MegaBytes written
interval: '1d', // rotate daily
compress: 'gzip' // compress rotated files
})
const logger = morgan('tiny', {
stream: rfsStream
})
module.exports.logger = logger;
