The Badgen Story

That's a service, that's a library, hooorey! - @tunnckoCore

Finally something to replace http://shields.io - @EGOIST

Epic work on Badgen! Porting the @dependabot badges over to it now. ⚡️ - @greybaker

The badgen library was born as an exploration of "is it possible to generate badge svg markup directly with JavaScript (without using pdfkit/canvas/puppeteer to measure text length)?". Result is better than I expected, Verdana (the de-facto font for badges) text width can be calculated precisely with a prebuilt char-width-table, even no need to worry about kerning 🤯

Then, logically, Badgen Service was born. I had a good time with shields.io, but as time goes by Shields gets slower, leaves more and more broken badges in READMEs. Badgen is trying to be a fast alternative with simplicity and flexibility. Its codebase is simple (2K LoCs vs Shields' 22K LoCs), well structured and fun to develop - it is pretty easy to add badge(s) for new service(s).

At the beginning I was considering between Now and Google Cloud Functions. Then Zeit announced Now CDN on the same day as badgen.now.sh (the PoC of Badgen Service)'s reveal, what a fate! Cloudflare powered Now CDN is a perfect choice for such service, caching and scalability in simplicity. Badgen is the fastest possible badge generating service out there. It's fast, it's reliable, it's globally distributed and cached, thanks to Now.

At the time of badgen.now.sh's reveal, it had only four live badges as demonstration. Since then, thanks to awesome people's help, Badgen keeps getting better at a fast pace. Welcome to join us, let's build the best badge service in the universe 🔥

Anatomy

• Written in latest, vanilla JavaScript => no build process
• Using badgen library to generate svg on the fly => fast & stateless
• Hosted on Now, serving behind Now CDN => faster & reliable
• Cache less than 4 minutes => fresh & hot
• Three endpoints in one server
  • https://badgen.net - classic style badges
  • https://flat.badgen.net - flat & square style badges
  • https://api.badgen.net - json “style” badges data (live badges only)
• Two badge types
  • static badge - url defined badge (subject, status, color)
  • live badge - show live status from 3rd party services
• Builtin Icons
  • Svg files in libs/icons will be auto loaded as builtin icon

Developing

We are using StandardJS style, make sure you have ESLint/Standard plugin on your editor and have autofix enabled.

Add live badge

If a service you wish to have is still missing here, we welcome new contirbutions. Basically, you need to add a file in libs/live-fns/[name-of-service].js and that's it. Take crates as an example:

• libs/live-fns/crates.js - main function for crates
• libs/live-fns/_index.js - index of all live-badges
• libs/index.md - the index.md holds examples

To ensure that your addition is working correctly start the development server with npm run dev.

Add icon

Badgen Server will auto load all svg files in libs/icons. Please make sure new icon is optimized using svgomg.

Deploy to Now

Badgen is stateless (not rely on db service). Deploy your own instance to Now with one single command:

now amio/badgen-service

Tracking Policy

Badgen use Google Analytics on doc pages (home, /docs/packagephobia, etc.), log request time to 3rd party service for live badges, like:

2018-08-09T04:16:30.947Z  #npm dt/chalk: 160.519ms
2018-08-09T04:16:31.195Z  #npm dependents/chalk: 365.045ms
2018-08-09T04:16:51.252Z  #david dep/olstenlarck/eslint-config-esmc: 445.893ms

And that's all. No tracking for end usage.
