Commander.js VS oclif

Visit the Commander.js reference.

In the previous article, I looked at a Commander to configure and accept cli options and assign it to a variable called program.

You can write a command line utility using zx or commander.js. Hit a public api, spit stuff out in the console, etc.

In your index.js you can do whatever you want, even create an interactive CLI (check commander).

There is clearly a whole load of repetition, so this should be fairly easy to build and parameterise. Essentially this will all just be string building so we won't need to use any particular libraries for most of this script. We will need a way to call ffmpeg though - and ffmpeg will need to be present too, of course. To call a CLI command we can use the package commander.

Commander.js is an NPM package that makes it easier to build CLI tools. You can find its documentation over here

You can also use npm package commander to make more complex command line tool with lot of options and sub commands.

commander - npm - Required. A library that lets you define the commands and their arguments, options, help, etc.

Throughout my time writing and updating my static-site generator, I've been using npm from the very foundation I use an npm package called commander. Therefore, it is obvious that for the tool that I will be using to publish my ssg, I will do so with npm.

The command line has thousands of tools, such as awk, sed, grep, and find available at your disposal that cut development time and automate tedious tasks. Creating a command line tool in Node.js isn't very complicated, thanks to a powerful library like Commander.js.

oclif is a library that helps create CLI applications using Node.js. If you are using a different programming language, search for a suitable library.

It is possible, oclif is a full featured framework produced by Salesforce and is used for the Salesforce and Heroku CLI applications. I have used oclif and pkg to bundle a standalone, though I was focused on MacOS not Windows. Any node application should work with pkg, though.

Interesting. TIL about the Open CLI framework that they all seem to be moving to: https://oclif.io/

https://oclif.io is a tool that helps you build command line tools with node. You can use it to help you create an executable for Linux, max, or windows that you can invoke from the command line.

Oclif to quickly click together CLI tools for kicking off and monitoring crawls, generating reports, etc.

During the second Ably Innovation Days, I started working on specifications for an Ably CLI. After the first day Phil and I started with a prototype based on oclif. We managed to create a working prototype in a day that lists Ably apps, and creates a new Ably app. This project is still Work In Progress. Once the CLI is in a releasable state, I'll create some content around this.

A command-line interface, often referred to as a CLI, is a program that allows users to type instructions and interact with a script that processes the input and produces an output. Node.js has a lot of packages that allows you to build CLIs, like args, minimist, and oclif.
