RecipeGo is a multi-user recipe management app where every cook has their own private library. You can add recipes by hand or import them directly from any food blog URL — the app fetches the page, parses the ingredients and steps, and pre-fills the form so you only need to review and save. A built-in serving scaler adjusts every quantity when you change the number of portions.
RecipeGo is a multi-user recipe management app where every cook has their own private library. You can add recipes by hand or import them directly from any food blog URL — the app fetches the page, parses the ingredients and steps, and pre-fills the form so you only need to review and save. A built-in serving scaler adjusts every quantity when you change the number of portions. When you add recipes to your shopping list, RecipeGo merges shared ingredients across dishes (so two recipes each calling for garlic appear as one line with the combined amount) and groups everything by supermarket aisle so you can move through the store in order. A weekly meal planner lets you drop recipes into Breakfast / Lunch / Dinner slots for each day, set how many people each meal is for, and then build the whole week's shopping list in one tap — works for your personal recipes and inside shared Rooms. When it's time to actually cook, cook mode takes over the screen: one step at a time in large type, a tickable ingredient list scaled to your chosen servings, arrow-key and big-button navigation, and the screen held awake so it never dims mid-recipe. The interface follows a Warm Editorial design — clean typography, a cream-and-terracotta palette, and no visual clutter.
A free Supabase project — supabase.com. The free tier is sufficient for local development and small deployments.
Docker Desktop(optional) — only required if you want to run the pgTAP database-level RLS tests locally with npm run test:db. Not needed for regular development or deployment.
Local setup
1. Install dependencies
npm install
2. Configure environment variables
Copy the example file:
cp .env.example .env.local
Open .env.local and fill in the three values. You find all three in your Supabase dashboard under Project Settings → API:
Variable
Where to find it
NEXT_PUBLIC_SUPABASE_URL
"Project URL" — looks like https://abcdefghijklm.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY
"anon / public" key under "Project API keys"
SUPABASE_SERVICE_ROLE_KEY
"service_role / secret" key under "Project API keys"
Security note:SUPABASE_SERVICE_ROLE_KEY bypasses Row-Level Security. Never expose it to the browser and never prefix it with NEXT_PUBLIC_. It is used only in server-side Route Handlers.
3. Link your Supabase project and apply migrations
The database schema lives in versioned migration files under supabase/migrations/. Apply them to your hosted Supabase project:
npx supabase login
npx supabase link --project-ref <your-project-ref>
npx supabase db push
Your project ref is the subdomain part of your Supabase URL — if your URL is https://abcdefghijklm.supabase.co, the ref is abcdefghijklm.
npx supabase db push applies every migration in order (profiles, recipes, shopping list, storage, rooms, meal planner, realtime, and more). You only need to run this once per environment, or again when new migrations are added.
Toggle Google on, paste your Client ID and Client Secret, and save.
Configure the allowed redirect URLs.
Go to Authentication → URL Configuration.
Under Redirect URLs, add:
http://localhost:3000/auth/callback (for local development)
https://<your-production-domain>/auth/callback (for the deployed app)
Set the Site URL to your production domain (e.g. https://recipego.vercel.app).
Email confirmations
By default, Supabase sends a confirmation email on sign-up. The confirmation link routes through /auth/callback, which exchanges the token for a session and redirects the user into the app.
If you want to skip this step during local development, you can disable confirmations in Authentication → Email in the Supabase dashboard (toggle off "Confirm email"). Re-enable it before deploying to production.
Tests
Logic and route handler tests (Vitest)
npm run test:run
This runs 175 tests across 29 files covering business logic (serving scaler, fraction formatting, aisle grouping, ingredient merging, unit conversion), UI components (cook mode, the URL import bar, the week planner), and the URL import route handler. No network or database connection is required.
Database RLS tests (pgTAP)
npm run test:db
This runs pgTAP tests that verify Row-Level Security policies at the Postgres level. It requires:
Docker Desktop running
A local Supabase instance started first: npx supabase start (first run pulls Docker images, which takes a few minutes)
The RLS tests are provided for local verification when Docker is available and have not yet been run in CI.
Security
The project was security-audited; the original findings are in
AUDIT.md. The main issue was an SSRF weakness in the URL-import
endpoint (/api/import-recipe): the target host was validated only as a string,
so a hostname that resolved to a private address (loopback, link-local, or the
cloud-metadata IP) — or a redirect to one — could make the server reach internal
services. It is fixed by resolving the host and rejecting
private/loopback/link-local/ULA addresses, pinning the socket to the validated IP
(closing the DNS-rebinding gap), and re-validating every redirect hop. The import
response is size-capped and the endpoint is rate-limited per user. Other audited
items (server-side image-upload limits, lint, CI) were addressed on the same
branch — see the commit history.
Deploy to Vercel
1. Push to GitHub
Commit your code and push to a GitHub repository.
2. Import into Vercel
Go to vercel.com → Add New → Project → import your GitHub repository.
Vercel detects Next.js automatically — no build settings need changing.
3. Set environment variables
In the Vercel project settings under Environment Variables, add all three variables from .env.example:
NEXT_PUBLIC_SUPABASE_URL
NEXT_PUBLIC_SUPABASE_ANON_KEY
SUPABASE_SERVICE_ROLE_KEY
Use the same values as your .env.local.
4. Deploy
Click Deploy. Vercel builds the app and assigns a domain like https://recipego.vercel.app.
5. Update Supabase redirect allowlist
After the deploy, go back to the Supabase dashboard → Authentication → URL Configuration:
Add https://<your-vercel-domain>/auth/callback to the Redirect URLs list.
Update the Site URL to https://<your-vercel-domain>.
If you are using a custom domain, substitute that for the Vercel-assigned domain.
End-to-end smoke checklist
Run through this checklist after your first deployment (or after any migration change) to confirm everything is wired together correctly.
Sign up with a new email address. After clicking the confirmation link you are redirected to the home page and a row appears in the profiles table in your Supabase dashboard.
Add a recipe manually. Click "New Recipe", fill in title, ingredients, and steps, save → the recipe appears in your library. Click it to open the detail page.
Import a recipe from a URL. Click "Import from URL", paste a link from a popular food blog (e.g. seriouseats.com or budgetbytes.com), click Import → the form is pre-filled with the parsed ingredients and steps. Review and save.
Scale servings. Open any recipe and change the serving count → all ingredient quantities update proportionally.
Shopping list merging and aisle grouping. Add two recipes that share a common ingredient (e.g. both call for garlic) to the shopping list. The list shows a single garlic line with the combined quantity, and all ingredients are grouped by supermarket aisle.
Check and clear. Check off individual items on the shopping list → the progress bar advances. Click "Clear checked" → checked items are removed.
Plan a week. Open "Plan", add a recipe to Monday Dinner (set the servings), add another to Tuesday Lunch, then click "Add this week to shopping list" → the shopping list shows the combined, aisle-grouped ingredients, scaled to the servings you set. (Requires the 20260630190000_meal_plan.sql migration to be applied.)
Tick off an eaten meal. On the plan, press ✓ on a meal → it stays in its slot, faded, and is still faded after a reload; "Add this week to shopping list" leaves it out. Press ✓ again → it's back to normal. (Requires the 20261006120000_meal_plan_eaten.sql migration to be applied.)
Live room sync (two browsers). Sign in as two different members of the same room in two separate browsers (or a normal + incognito window), both open the same room. In browser A: check a shopping-list item, add a recipe, tick a meal on the room's plan, rename the room, or accept an invite → browser B reflects the change within ~1 second without reloading. (Requires the migration to be applied and Realtime enabled for the project.)

Live plan sync (two tabs). Open your own plan in two tabs (or on your phone and your computer). Tick a meal in one → the other fades it within ~1 second without reloading; untick it → it's back to normal. (Same migration and Realtime setting as room sync.)
Sign out. Click sign out → you are redirected to /login. Navigating to a protected page (e.g. /recipes) while signed out also redirects to /login.
