This tool is created for working with and implementing Escher Auth into web projects, without the requirement to modify the code base.

The client that use escher-cli must implement the use of HTTP_PROXY like curl does for outgoing requests.

For Server, it must use the PORT env variable like at heroku in order to use the escher validation with the cli tool

you must also configure your env with the applications escher configuration such as KEY_POOL for example.

curl here is only an example application to demonstrate the usage

escher-cli curl google.com

Again, you must set the port number in order to enable escher-cli validation feature. Your server also expected to use the $PORT env variable for setting it's own listening. This is a common thing at heroku Procfile for example

export PORT="$THE_PORT_NUMBER_THAT_I_EXPECTED_TO_USE"

than all is left to use your application

escher-cli ./my-service-app
escher-cli bundle exec rackup -p $PORT
