Use knobs if you worship at the church of the 12 Factor App

A knob is a wrapper for an environment variable. It can:

  • Read and write an environment variable
  • Make sure it is of the expected type
  • Validate a value is good.

knobs will search for a nominated environmental file (default .env) and load that into the environment. A knob is type aware, configured from the environment and its value can be persisted to ease the creation of configuration files.
