vorpal VS yargs

Vorpal.js is a framework for building mature, immersive command-line applications.

I occasionally try that as well and it sometimes helps but not for things like node apps that use https://vorpal.js.org REPLs. They just aren't usable in shell-mode.

Got it, so more about the general idea of using Node to interact with a shell. Fair points but I'm not sure that's where zx falls. I'm looking at it in relation to projects like commander, oclif, and vorpal— frameworks for authoring and packaging local-use CLI tools written in JS, typically aimed at people who know JS and work in a terminal but don't know shell scripting. Those have the overhead of learning a framework, and don't do anything to help you work with the shell. zx seems to come from the other direction: instead of an esoteric framework, shell concepts and shell commands in a Node script.

Assuming the project uses node, and admittedly it's a lil overkill, but you could use vorpal.

Are you wanting to run your nodejs app, and then control it within the same terminal it is running in? If so, take a look at vorpal

Your tool now automates project setup, but there's room for improvement. Consider adding more features or handling user input to customize the project structure. Explore packages like yargs for parsing command-line arguments. You can learn more about yargs through their official documentation here.

This code snippet uses yargs, a Node.js package, to parse command-line arguments in a POSIX-compliant way, including support for short and long-form options. You could also use the popular commander defined as a complete node.js command-line interface.

This feature was implemented by adding a new argument option -l or --lang in yargs as below.

Creating CLIs with yargs is a piece of cake. For LZ4 there is a streaming implementation on npm which is a single function and also happened to decompress my files without any errors. Everything else is out-of-box Node.js.

Backend is more tricky. - RESTful APIs I prefer Koajs - For a RPC/microsevice, I have only used gRPC - For a CLI, yargs and inquirer

To accomplish this task, I added a new option using the yargs module. This allows me to read whatever the user inputs after using -l/--l. Following this, I added a conditional statement that defaults to en-CA whenever a language code is not inputted.

You can build them from scratch, or use one of many specialized libraries on NPM, like commander, yargs, blessed, terminal kit, prompts, and many more.
