LoopBack project files and directories are in the application root directory. Within this directory the standard LoopBack project structure has three sub-directories:

  • server - Node application scripts and configuration files.
  • client - Client JavaScript, HTML, and CSS files.
  • common - Files common to client and server. The /models sub-directory contains all model JSON and JavaScript files.
  • definitions - API and product definition YAML files (IBM API Connect only).
