Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

A command-line interface (CLI) framework for Node.js and web browser

build status badge npm version badge github stars badge

The @carnesen/cli package includes runtime JavaScript files (ES2019 + CommonJS) and TypeScript type declarations (3.7+). It has no npm dependencies and is known to work with Node.js 12+ and all modern web browsers.

Features

  • Easy to use: We ❤️ CLIs and want to use them everywhere for everything. This library makes it easy to create beautiful, well-behaved, type-safe CLIs for Node.js and for web browsers.

  • Isomorphic: As far as we know, this is the only isomorphic JavaScript CLI framework. Run your browser CLI in a terminal emulator like our online examples or in the browser's built-in terminal, the JavaScript console!

  • Intelligent types: This is first and foremost a TypeScript library. All components are intelligently typed, and our built-in parsers ensure that the types are respected at runtime.

  • Automatic documentation: Build your CLI with our factories, and we'll automatically generate pretty-good command-line usage out of the box. You can add descriptions and custom <placeholder>s to your command objects too, and we'll automatically fold the text to fit the user's terminal.

  • Built-in color decoration: Bring your CLI to life with our color helpers injected automatically into your command action function.

  • Hidden commands Add "hidden=true" to any argument/command/group, and we'll hide it in the automatic usage docs. We use this feature for easter eggs and internal-only/beta commands.

  • Automatic autocomplete (Coming some day!): Autocomplete supercharges a CLI. We've implemented automatic autocomplete in the live examples and plan to add this as a feature to the core library in a future release.

  • REPL (Coming some day!): The live examples are implemented as custom REPL. In a future release we'll lift that code into the framework to make it just as easy to build a REPL as it is to build a CLI.

Stability

This library has 100% test coverage and heavy usage by its authors but should be considered 0.x beta software.
