The custom Logger for your Node-Express app.
A HTTP request logger middleware for nodeJs
This is a Node.js module available through the
npm registry. Installation is done using the
npm install command:
$ npm i borgenIf you use yarn:
$ yarn add borgenIf you use pnpm:
$ pnpm add borgenconst { Logger, Borgen } = require('borgen');import { Logger,Borgen } from 'borgen';This is the simplest way you can use Borgen, you can however customize
the colors it uses in logging.
const express = require('express');
const { Logger, Borgen } = require('borgen');
const app = express();
app.use(Borgen({}))
Logger.info({message: 'This is an informational message.'});
Logger.warn({message:'This is a warning message.'});
Logger.error({message:'This is an error message.'})
app.listen('3002', () => {
Logger.info({ message: 'The server is running on port 3002'});
});blackredgreenyellowbluemagentacyanwhiteblackBright(alias:gray,grey)redBrightgreenBrightyellowBrightblueBrightmagentaBrightcyanBrightwhiteBright
Logger.info({message: 'This is an informational message.'});
Logger.warn({message:'This is a warning message.'});
Logger.error({message:'This is an error message.'})You can fully customize the color for your log.
Logger has three options:
- Logger.info( )
- Logger.warn( )
- Logger.error( )
Each Logger option has defaults and will fallback if no arguments are passed
const express = require('express');
const { Logger, Borgen } = require('borgen');
const app = express();
app.get('/test', (req, res) => {
Logger.warn({ message: 'This is an warning', infoColor: 'yellow', messageColor: 'yellowBright' });
res.send('Hello world').end();
});
app.get('*', (req, res) => {
Logger.error({ message: 'This route does not exist', infoColor: 'red', messageColor: 'redBright' });
res.send('404 not found');
});
app.listen('3001', () => {
Logger.info({ message: 'The server is running on port 3001', infoColor: 'cyanBright', messageColor: 'whiteBright' });
});messageThis is the information you want to be logged to the console.infoColorThis is the color of the first section of the log.messageColorThis is will be the color of the message you want to log.
Note: infoColor and messageColor are optional and if not passed the logger will
will use the fallback configuration.
Use CTRL + space or Options + space with infoColor and messageColor to get all
the colors available.
This middleware is able to handle all you incoming requests and you can
customize the colors they are logged in.
app.use(Borgen({}))You can fully customize the color for your incoming requests.
const express = require('express');
const { Logger, Borgen } = require('borgen');
const app = express();
app.use(
Borgen({
methodColor: {
GET: 'greenBright',
POST: 'yellow',
PUT: 'gray',
PATCH: 'gray',
DELETE: 'redBright'
},
routeColor: 'gray',
statusColor: 'cyan',
resTimeColor: 'gray',
statusCodesCl: { serverErr: 'red', clientErr: 'yellow', redirects: 'cyan', success: 'greenBright' }
})
);
app.listen('3001', () => {
Logger.info({ message: 'The server is running on port 3001', infoColor: 'cyanBright', messageColor: 'whiteBright' });
