Returns true if the current environment is a Continuous Integration
server.
Please open an issue if your CI server isn't properly detected :)

npm install is-ci --save
Programmatic Usage
const isCI = require('is-ci')
if (isCI) {
  console.log('The code is running on a CI server')
}
CLI Usage
For CLI usage you need to have the is-ci executable in your PATH.
There's a few ways to do that:
- Either install the module globally using 
npm install is-ci -g - Or add the module as a dependency to your app in which case it can be used inside your package.json scripts as is
 - Or provide the full path to the executable, e.g.
./node_modules/.bin/is-ci 
is-ci && echo "This is a CI server"
