Introduction
This article will help you set up your logs with papertrail with your existing Node.js application
Pre-requisites
Basic knowledge of Node.js, Yarn/NPM, importing and exporting nodejs packages within files.
I will talk in the first person so bear with me 😀
Lets Start Stepwise
- I created a new directory on my desktop and named
logging - Then fired up a terminal in this folder.
- Created a basic project using
yarn, feel free to usenpm
yarn init
- Added 3 packages
yarn add node-cron pino pino-papertrail
- Created a
logger.jsfile which will export our Pino transport logger.
// logger.js
module.exports = require('pino')();
- Create an entry file for our project execution
index.js
var cron = require('node-cron');
// import our logger
const logger = require('./logger');
// add a cron that will run every 15 seconds
cron.schedule('*/15 * * * * *', () => {
logger.info('logging every 15 seconds');
});
- Created a new log destination using the big button below.
Used next screen with default settings, hit Create
Next screen will show up to your log destination variables
Starting Our Application
In our project terminal, use this command to throw all our logs to papertrail. Update your variables (obviously) for host, port and app name accordingly.
node index | pino-papertrail --host <logs.papertrailapp.com> --port <PORT> --appname <NAME_OF_APP>
Output : Project Console
Here’s my terminal console
