This is home to Shields.io, a service for concise, consistent, and legible badges in SVG and raster format, which can easily be included in GitHub readmes or any other web page. The service supports dozens of continuous integration services, package registries, distributions, app stores, social networks, code coverage services, and code analysis services. Every month it serves over 470 million images.

Shields is a community project. We invite your participation through issues and pull requests! You can peruse the contributing guidelines.
When adding or changing a service please add tests.
This project has quite a backlog of suggestions! If you're new to the project, maybe you'd like to open a pull request to address one of them:
You can read a tutorial on how to add a badge.
- Install Node 8 or later. You can use the package manager of your choice. Tests need to pass in Node 8 and 9.
- Clone this repository.

npm run buildto build the frontend.
npm startto start the server.
http://[::]:8080/to view the home page.
To generate the frontend using production cache settings – that is,
badge preview URIs with
maxAge – run
LONG_CACHE=true npm run build.
To analyze the frontend bundle, run
npm install webpack-bundle-analyzer and
ANALYZE=true npm start.
Snapshot tests ensure we don't inadvertently make changes that affect the
SVG or JSON output. When deliberately changing the output, run
SNAPSHOT_DRY=1 npm run test:js:server to preview changes to the saved
SNAPSHOT_UPDATE=1 npm run test:js:server to update them.
Daily tests, including a full run of the service tests and overall code coverage, are run via badges/daily-tests.
Hosting your own server
There is documentation about hosting your own server.
b.adge.me was the original website for this service. Heroku back then had a thing which made it hard to use a toplevel domain with it, hence the odd domain. It used code developed in 2013 from a library called gh-badges, both developed by Thaddée Tyl. The project merged with shields.io by making it use the b.adge.me code and closed b.adge.me.
The original badge specification was developed in 2013 by Olivier Lacan. It was inspired by the Travis CI and similar badges (there were a lot fewer, back then). In 2014 Thaddée Tyl redesigned it with help from a Travis CI employee and convinced everyone to switch to it. The old design is what today is called the plastic style; the new one is the flat style.
