chalk VS Express

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).

First, we import express. The Express framework allows us to create routes that will respond to webhook POST requests and serve an HTML file when a GET request is made to the root of the site.

Basic Knowledge of Express

Express.js Documentation

In the JavaScript ecosystem, there are guides for enabling SAML-based enterprise single sign-on in AdonisJS, Express.js, Next.js, Remix, and React with an Express.js backend.

Starting off strong with Express.js, the cool kid on the block for building web apps. It's lightweight, flexible, and doesn't throw a tantrum when you ask it to scale. With Express, you can handle HTTP requests like a pro, play around with middleware, set up routes without breaking a sweat, and render views that make your app look stunning. Big names like Netflix and Uber are already on board, and if it's good enough for them, it's definitely worth a peek.

Now we can install both Express and Socket.io libraries:

app.listen(3000); ``` Now you can run your server by executing `node index.js`. Your web application will be accessible at http://localhost:3000/, where you'll see "Hello, world!" displayed in your browser. Congratulations! 🎉 You've successfully set up basic routing with Express.js! This guide covered only the tip of the iceberg when it comes to utilizing Express.js features. Explore its extensive documentation (https://expressjs.com/) to discover more possibilities. Remember, with Express.js, you have the power to build efficient and scalable web applications. Happy coding!

Converting a large Express.js application from JavaScript to TypeScript can be a challenging task. For many applications, this represents a significant portion of their technical debt, as the process may span many days, if not months, and new changes are typically not allowed during the conversion.

Nitro is a nice https webserver that you can deploy everywhere. Comparing it to express, it doesn't need weird middlewares for json, it has a simple way to support caching, a file system router, tasks and scheduled tasks that avoid quite a few shell scripts, db:migrations etc, plugins, KV storages, SQL connectors, websockets...
