How this sample app works

    +
  • This app was deployed to Heroku using Git.
  • When Heroku received the source code, it fetched all the dependencies in requirements.txt, creating a deployable build artifact.
  • The platform then spins up a dyno, a lightweight container that provides an isolated environment in which the build artifact can be mounted and executed.
