So, to change it into the readable format, you mention the prettyPrint option in the exported pino function and, after that, your loggerService.js file should look something like this: const pino = require('pino')Ĭonfiguring your loggerService is covered in later steps. But, this can create a little problem with this logger-service: the JSON log that you will see in a minute is not readable. However, you are not passing any options currently because you will configure this logger service in the later steps. The exported pino function takes two optional arguments, options, and destination, and returns a logger instance.

This code defines the most basic logger service that you can create using Pino-logger. Inside of this new directory, create a new loggerService.js file and add the following code: const pino = require('pino') Start by creating a new services directory in the root folder: mkdir services In this step, you create a Pino-logger service with different levels of logs, like warning, error, info, etc.Īfter that, you configure this logger-service in your app using Node.js middleware.

npm install Īt this point, you are ready to create a logger service with Pino. You need the following command in your command-line tool from the project’s root directory. These include Pino, Express-Pino-logger, and Pino-pretty. In this step, you install the latest versions of dependencies required for the logging. The -g flag depicts that the dependency is installed globally and, to perform something globally, you are adding the -force flag in the command. So, write this command in your terminal: npm install -g -force nodemon

You can download nodemon so that each time you save changes in your codebase, the server automatically restarts and you don’t have to manually start it again with node server.js. Since this article is about implementing the logger, you can follow “How To Perform CRUD Operations with Mongoose and MongoDB Atlas” to create your basic CRUD application in Node.js.Īfter completing that tutorial, you should be ready with a Node.js application that includes create, read, update, and delete routes.Īlso, at this point. You do this because it is better to implement logging functionality in a codebase that mimics a real-world application. In this step, you set up a basic Node.js CRUD application using Express and Mongoose. An understanding of command-line tools or integrated terminals in code editors.ĭownloading and installing a tool like Postman is recommended for testing API endpoints.Familiarity with setting up a REST API without any authentication.Familiarity with using Express for a server.Prerequisitesīefore following this tutorial make sure you have: When you’re done, you’ll be able to implement logging with coding-best practices in your Node.js application using Pino-logger.

You will see how to save these logs in a separate log file.

You will learn how to prettify the logs in your terminal as well as whether or not to include the JSON response in your logs.

You will study how to configure logging services with different logging levels.

And its 7.8K stars on GitHub are a testament to that. With Pino as a dependency for a Node.js application, it becomes effortless to implement logging, and even storing these logs in a separate log file.

With logging, you can store every bit of information about the flow of the application. This tutorial is about implementing logging in a Node.js application using Pino-logger. It also helps save developers hours of debugging work. Logging helps developers comprehend what it is that their code is doing. Logging, on its own, is a key aspect of any application.
