docopt.sh VS nvm

I like that this generates readable output that could pass as hand-written code.

The docopt.sh output looks like it went through a JS minifier. Or is there a way to change that? If so I think it should default to that.

If you want to avoid having to write your own args parser everytime or think getopt is a pain, you should check out my little project:

https://github.com/andsens/docopt.sh

No dependencies, the code is directly inlined into your script, and you write the args parser by writing the help-text.

Honestly, I left it as a gist because even though it reduces boilerplate, getopts is still not a great flag parser (e.g. only supports single-letter flags, and no type safety or other validation aside from boolean / string). I use it in my shell environment since I have lots of shell functions and I don't care to pull in a "real" parser into my shell, but if I was writing any sort of more complex standalone script I probably wouldn't use it. Check out docopt if you haven't seen it, I've been meaning to give that a whirl at some point.

nvm - Node version manager

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.
