nvm VS chalk

Node.js + Nvm - runtime for javascript without a browser

Install Node.js if it hasn't been installed. There are several ways to install Node.js. You may download the installer from the official website, or install it with tools like NVM. After installation, run this command to verify its installation.

Our server also needs Node.js to run our app. We could install the binary directly, but I prefer to use a tool called NVM, which allows us to easily manage Node versions. We can install it with this command:

By setting up your environment in isolation, you can prevent yourself from a lot of issues when experimenting with code. It makes your code behave more predictable due to the defined state of the runtime environment you are working with. This article should provide you with enough information to get started, but obviously, there is a lot more power embedded in NVM, Virtual Environment and RBEnv. So make sure to check their documentation.

I highly recommend setting up nodejs with a version manager, nvm was and still is a popular option, however, I now recommend and have been using fnm, a simpler and faster alternative to manage my nodejs versions.

The purpose of a version manager is to help you navigate or install any tools for development easily. Version Manager can be one tool for each dependency (e.g. NVM, g) or One tool for all dependencies (e.g. asdf, mise).

I usually develop on Windows so I installed NVM for Windows from here, but if you’re on other OS I’m sure you can find a version that supports it, probably this is the answer.

This was a very quick introduction to how I setup NodeJS on my environment using nvm. If you have any questions please refer to the official documentation or contact me via my Social Links.

4. Chalk

Chalk: Provides an easy way to stylize terminal strings with various colors and text formatting in Node.js, aiding in creating visually appealing command-line outputs

Chalk is a popular choice for adding colors to CLI output while maintaining readability.

Librerías: Chalk winston, log4js

Today the most popular library and de facto standard is the chаlk. The chalk has rich functionality, is fast but not ideal. It lacks some useful features.

This is a new tutorial on how to create a command line interface application, and our application today is a Mortgage Calculator. I used in this program packages such as 1- inquirer for interactive questions and answers: https://www.npmjs.com/package/inquirer 2- Sqlite3 DBMS 3- Chalk for colorful output in the terminal: https://www.npmjs.com/package/chalk

One of the libraries I used most that went full-ESM is Chalk. They released v5 over a year-and-a-half ago (November 2021) with ESM-only support and haven't updated v4 - their last iteration that supported CommonJS - since. If you go into their GitHub Issues section, you'll see a number of issues raised about CommonJS support, most of which are just responded to with a link to a post they made about switching over. Fair enough. I guess if I had to constantly answer the same question over and over, I might do the same.

To colorize my logs, I used a chalk package and created a logger utility:

We will add some dependencies to help us deal with CLI behaviours (inquirer) and text coloring (chalk).
