Dev setup

Troubleshooting

Linux/arm64: `@rollup/rollup-linux-arm64-gnu` missing (Vite/Rollup optional dependency)

If npm fails with errors like Cannot find module @rollup/rollup-linux-arm64-gnu, switch to pnpm and re-install. This repo is already set up for pnpm lockfiles; use the scripts below.

1) Prereqs

Node.js 22+
MongoDB (local or remote)

2) Environment variables

Backend

Copy and edit:

backend/.env.example → backend/.env

Required (typical):

PORT (default 5055)
MONGODB_URI
MONGODB_DB
JWT_SECRET
ALLOWED_ORIGIN (e.g. http://localhost:5173)

Frontend

Copy and edit:

frontend/.env.example → frontend/.env

Required:

VITE_BACKEND_URL (e.g. http://localhost:5055)

3) Install

From repo root:

npm --prefix app install

4) Run

From repo root:

npm run dev:app

This runs:

backend: http://localhost:5055
frontend: http://localhost:5173

OAuth callback route

The OAuth redirect URI is:

/oauth/callback

Make sure your hosting serves index.html for that path (SPA history fallback). During local dev, Vite already handles this.
