Environment Variables¶

List every environment variable the project needs, what it's for, and where to get a value. Never commit real secrets to this file or the repo — use a .env.example file in each app and keep real .env files git-ignored.

Server¶

Variable	Description	Example
`DATABASE_URL`	Connection string for the database	`postgres://user:pass@localhost:5432/tutordb`
`AUTH_PROVIDER_*`	Credentials for the chosen auth library/service	fill in
`PORT`	Port the API listens on	`4000`

Client¶

Variable	Description	Example
`VITE_API_URL` / `NEXT_PUBLIC_API_URL`	Base URL of the API	`http://localhost:4000`

External integrations¶

Document the external API you integrate with here (per the brief's "Integration" requirement), including which env vars it needs.

Variable	Description
e.g. `TIMETABLE_API_KEY`	Key for the external timetable/calendar integration
