debug VS Inquirer.js

Another way to solve this is to have the logs in place, but only enable them conditionally. If you enable all the logs are the time, you only get a lot of noise that won't help you. If you are using JavaScript, you can use the package debug to add logs that are active by the DEBUG environment variable.

I'm using the debug package: https://www.npmjs.com/package/debug, but some reason I don't see millisecond diffs, which would be really useful.

Although it's used by Express, it's indeed more broadly, the way a popular NPM package called debug works, which is used internally in Express too. Under the hood, the debug package expects the DEBUG environment variable to determine what debug messages to print (could be on the console, or into a file, or into stdout to be collected by a log aggregator service).

Finally, if they're logs you want to be able to inspect in production without printing them to the console by default, you can use debug.

It is a drop-in, TypeScript replacement to enhance the widely popular https://www.npmjs.com/package/debug (230k weekly downloads).

debug - npm - Required. A popular library to write debug logs.

I strongly recommend using the debug package from NPM to organize your log messages

Use the [debug npm library](https://www.npmjs.com/package/debug) to disable your logging unless someone provides the right environment variable (e.g. DEBUG=* which enables all logging)

A lot of tools rely on the NODE_ENV environment variable for that, React included. Another great package that’s pretty popular is https://www.npmjs.com/package/debug You can create namespaces and then filter the logs you are interested in.

Inquirer.js is a handy tool for adding interactive prompts to your CLI.

There is a CLI application based on Inquirer. Potentially, it could be another CLI library, say something from the following list. Our goal is to provide integration tests. But before that, let's look at the related terminology.

inquirer

If you boil plop down to its core, it is basically glue code between inquirer prompts and handlebar templates.

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

We can easily achieve that with the inquirer package. This package allows you to ask different types of questions, such as input questions (open-text questions), confirmation questions (Yes/No), etc.
