This is home to [Shields.io][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.
In addition to hosting the shields.io frontend and server code, this monorepo
hosts an [NPM library for generating badges][gh-badges], and the badge design
specification.

------------
Shields is a community project. We invite your participation through issues
and pull requests! You can peruse the [contributing guidelines][contributing].
When adding or changing a service [please add tests][service-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:

Using the badge library
-----------------------
```sh
npm install -g gh-badges
badge build passed :green .png > mybadge.png
```
```js
const badge = require('gh-badges')
// Optional step, to have accurate text width computation.
const format = {
text: ['build', 'passed'],
colorscheme: 'green',
template: 'flat',
}
badge.loadFont('/path/to/Verdana.ttf', err => {
badge(format, (svg, err) => {
// svg is a string containing your badge
})})
```
View the [documentation for gh-badges][gh-badges doc].
**Note:** The badge library was last released in 2016.
[![npm version](http://img.shields.io/npm/v/gh-badges.svg)](https://npmjs.org/package/gh-badges)

Development
-----------
1. Install Node 8 or later. You can use the [package manager][] of your choice.
Tests need to pass in Node 8 and 9.
2. Clone this repository.
3. Run `npm install` to install the dependencies.
4. Run `npm run build` to build the frontend.
5. Run `npm start` to start the server.
6. Open `http://[::]:8080/` to view the home page.
To generate the frontend using production cache settings &ndash; that is,
badge preview URIs with `maxAge` &ndash; run `LONG_CACHE=true npm run build`.
To analyze the frontend bundle, run `npm install webpack-bundle-analyzer` and
then `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
snapshots, and `SNAPSHOT_UPDATE=1 npm run test:js:server` to update them.
The server can be [configured][sentry configuration] to use [Sentry][sentry].

Hosting your own server
-----------------------
There is documentation about [hosting your own server][self-hosting].

History
-------
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][old-gh-badges], both developed by [Thaddée Tyl][espadrine].
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][olivierlacan]. 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.
You can read more about [the project's inception][thread],
[the motivation of the SVG badge specification][motivation], and
[the specification itself][spec].
