How to organize a Node/Express project — Basic

Misc / Other Project & repo setup

Separate app entry, routers, controllers, services, and database code into predictable folders.

Learn: A consistent folder layout helps you find code quickly and mirrors how professional teams organize Express APIs. Each resource gets router + controller + service files; shared pieces (db, errors, config) live at the top level.

Supplementary examples

Adding a new resource (tags)

src/tags/
  tags.router.js      # URLs only
  tags.controller.js  # req/res
  tags.service.js     # Knex queries

Course example

src/
  app.js                 # Express app + global middleware
  server.js              # listen(PORT)
  config/                # logger, env helpers
  errors/                # notFound, errorHandler
  db/                    # knex connection, migrations, seeds
  users/
    users.router.js
    users.controller.js
    users.service.js
