The Badgen Story
That's a service, that's a library, hooorey! - @tunnckoCore
Epic work on Badgen! Porting the @dependabot badges over to it now.
The badgen library was born as an exploration of "is it possible to generate badge SVG markup directly (without using pdfkit/canvas/puppeteer to measure text width)?". The result is better than I expected, Width of Verdana (the de-facto font for badges) text 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).
In the beginning, I was considering both Vercel and Google Cloud Functions. Then Vercel announced Edge Network on the same day as badgen.now.sh (the PoC of Badgen Service)'s reveal, what a fate! Cloudflare powered Vercel Edge Network 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 Vercel.
At the time of badgen.now.sh's reveal, it had only four live badges as demonstrations. 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
- Written in TypeScript
- Using badgen library to generate svg on the fly
- Two visual styles
- Two badge types
- static badge - URL defined badge (label, status, color)
- live badge - Show live status from 3rd party services
- Builtin Icons & External Icon Support
- see badgen-icons
- Docker image amio/badgen
start dev server
npm run dev
start prod server
npm run build && npm start
run with docker image
docker run -p 3000:3000 amio/badgen
Add Live Badge
If a service you wish to have is still missing here, we welcome new contributions. Basically, you need to add a file in
api/[name-of-service].ts and that's it. Take /crates as an example:
- api/crates.ts - main function for crates badges
- libs/badge-list.ts - contains index of all live badges
To ensure that your addition is working correctly, start the development server with
npm run dev.
The /runkit support would be super handy for prototyping a new live badge.
Badgen do not collect any identifying information.
