Getting Started

git clone https://github.com/tim-peters/sessionplan.git
cd sessionplan
npm install
npm run dev

Open http://localhost:5173 (or the port Vite assigns) in your browser.

Self-Hosting

Sessionplan is fully functional without a backend — all data is stored locally in the browser. An optional backend enables the Dynamic Link feature for real-time sync between multiple users.

Dynamic Link (optional backend)

To enable the Dynamic Link feature, deploy a PHP backend that implements the /data/sessions.php REST API (see the API reference). Then set the endpoint URL:

# .env
VITE_SESSIONS_API=https://your-server.example.com/data/sessions.php

If VITE_SESSIONS_API is not set, the Dynamic Link toggle is still available in the UI but all requests will fail gracefully — the planner continues to work fully locally.

See ARCHITECTURE.md for the API contract.
