☀️ Track food without judgment.

Clean Slate is a free calorie tracker. It is designed for people who struggle with:

• Binging
• Self-compassion
• Logging food consistently
• Dieting itself

It can do stuff like:

• Search and log food
• Quick add calories and protein
• Create custom foods and recipes
• Scan barcodes
• Track exercise

Nope! We maintain a free instance at cleanslate.sh. It offers free accounts with social login (e.g. Login with Google).

Clean Slate is licensed under the BSL 1.1 license. The license is quite permissive. You can view the code, contribute to Clean Slate, or host it yourself. You just cannot launch a commercial version of Clean Slate (i.e. one that makes money). This license is used by projects such as Sentry.io and MariaDB. You can read more about the license here.

Hosting Clean Slate is easy. You just need a Linux server with Git, Docker, and Docker Compose installed.

1. Run git clone https://github.com/successible-org/cleanslate on your server. cd inside the newly created folder called cleanslate.

2. Create a .env file in the cleanslate folder with these variables. Replace <> with your values.

# Required
POSTGRES_PASSWORD=<your-desired-password>
NEXT_PUBLIC_HASURA_DOMAIN=<your-server-domain>
HASURA_GRAPHQL_ADMIN_SECRET=<long-secret-value>
HASURA_GRAPHQL_CORS_DOMAIN=https://<your-server-domain>

3. Run bash deploy.sh. This script will build and start the database, client, and server via Docker Compose. The client is what the user will interact with. It runs on http://localhost:3000. The server (Hasura) runs on port 8080. The database (PostgreSQL) runs on ``

4. On your domain, point a reverse proxy, like Caddy or Nginx, to http://localhost:3000 and http://localhost:8080. Use the proxy paths, as shown in a sample Caddyfile. If you wish to use the Caddyfile, replace XXX with your own domain.

XXX/v1* {
	# API (Hasura)
	reverse_proxy localhost:8080
}

XXX/v2* {
	# API (Hasura)
	reverse_proxy localhost:8080
}

XXX/console* {
	# Admin panel (Hasura).
	reverse_proxy localhost:8080
}

XXX {
	# Static files (Clean Slate)
	reverse_proxy localhost:3000
}

Note: Clean Slate must be served over https to function. We recommend Caddy ¹ as the reverse proxy, and have tested Clean Slate with it. Caddy is great because it handles https automatically and for free via Let's Encrypt ².

5. Go to the https://<your-domain>/console. Log in with your HASURA_GRAPHQL_ADMIN_SECRET defined in .env. Click Data, then public, then profiles, then Insert Row. On this screen, enter no input. Instead, click Save. This will create a new Profile. Click to Browse Rows. Take note of the authId of the row you just made. That is your (very long) credential to log in.

6. You can now log in to https://<your-domain> with that credential!

7. To deploy the newest version of Clean Slate, run bash deploy.sh again. Read CHANGELOG.md every time before you deploy to read about any breaking changes.

This section covers the "essentials" on deploying Clean Slate. However, you should also read the appendix for more details.

Run Clean Slate locally, make changes, and then submit a pull request on GitHub.

Note: Clean Slate is written in React and TypeScript, with Next.js as the framework. It uses Hasura as the backend and PostgreSQL as the database.

Here's how to run Clean Slate locally:

• Install Git, Docker Desktop, Hasura CLI, Node.js (LTS), and Caddy. Make sure Docker Desktop is running.

• Run npm run dev after cloning down the repository. This will spin up these servers:

  • Hasura (API): http://localhost:8080.
  • Hasura (Console): http://localhost:9695.
  • Next.js: http://localhost:3000.
  • PostgreSQL: http://localhost:1270

• Navigate to http://localhost:3000 and login with token 22140ebd-0d06-46cd-8d44-aff5cb7e7101.

Note: To test the deployment process locally, install caddy. Then, run bash deploy.sh after creating the .env below in your cleanslate folder. Then, run caddy start -c Caddyfile.dev. caddy will pick up the Caddyfile.dev and serve Clean Slate on https://localhost.

Note: If you want to proxy the development version of Clean Slate to test on a mobile device, install ngrok. Run ngrok http --host-header localhost https://localhost:443 in another terminal.

# .env for testing the hosting process locally. Do not use in an actual production setting!
POSTGRES_PASSWORD=XXX
NEXT_PUBLIC_HASURA_DOMAIN=localhost
HASURA_GRAPHQL_ADMIN_SECRET=XXX

Clean Slate uses the default postgres user and postgres database. It also runs Postgres (15) in a container managed by Docker Compose, rather than on the server itself. If you do not like that behavior, you should use a custom docker-compose.yml.

Make a copy of our docker-compose.yml ³ and call it custom.yml. Remove database from the list of services and the cleanslate volume. Update HASURA_GRAPHQL_DATABASE_URL to point to your database. Finally, run export COMPOSE_FILE=custom.yml; bash deploy.sh whenever you deploy.

Clean Slate was built around delegating authentication to Firebase. Firebase is a very secure authentication service maintained by Google. It is our default recommendation for any instance of Clean Slate with more than a few users. Consult the Using Firebase section of the appendix for how to set up Firebase with Clean Slate.

However, Firebase is too complex for the most common hosting scenario. That scenario is a privacy conscious user who wants to host Clean Slate for individual or family use. Hence, our default authentication system, authId, works differently.

The authId system is incredibly simple. There is no username or password. Clean Slate does not even require a server that can send email. Instead, Clean Slate uses very long tokens (uuid4) stored as plain text in the database. Because each token is very long and generated randomly, they are very secure. And if you ever need to change the value of the authId, you can just use the Hasura Console. If you would rather not use the authId system, you will need to use Firebase instead.

• Create a new Firebase project.
• Enable Firebase authentication.
• Enable the Google provider in Firebase.
• Create your .firebaserc locally in the root with the following content. Example:

{
  "projects": {
    "default": "your-firebase-project-name"
  }
}

• Create a firebase-config.json locally filled with the content of firebaseConfig. You can find that on your Project Settings page on Firebase.

{
  "apiKey": "XXX",
  "appId": "XXX",
  "authDomain": "XXX",
  "messagingSenderId": "XXX",
  "projectId": "XXX",
  "storageBucket": "XXX"
}

• Login with Firebase locally via npx firebase login.

• Run npx firebase deploy to deploy the Firebase functions in /functions.

You can now run Firebase locally or in production with these last steps.

Locally (Linux or Mac):

• Install jq
• Mac only: Install and use GNU sed
• Run export FIREBASE='true'; npm run dev

Production (Linux):

• Add the environment values to the correct location.

These environment values are added to the static website via .env (Step #2). Replace XXX with your own.

# This forces Clean Slate to use Firebase over the authId system
NEXT_PUBLIC_USE_FIREBASE="true"
# This is required for Firebase to work on the client
NEXT_PUBLIC_HASURA_DOMAIN="XXX"

# You can find your project config in your Firebase project settings
NEXT_PUBLIC_FIREBASE_CONFIG={"apiKey":"XXX","appId":"XXX","authDomain":"XXX","messagingSenderId":"XXX","projectId":"XXX","storageBucket":"XXX"}

# Just setting a value as true does not turn on the provider
# See the Firebase documentation for how to configure each provider.
# Google should start as true but that is one click to configure in Firebase
# And you always need one provider enabled. Otherwise, no one can log in.

NEXT_PUBLIC_LOGIN_WITH_GOOGLE="true"
NEXT_PUBLIC_LOGIN_WITH_APPLE="false"
NEXT_PUBLIC_LOGIN_WITH_GITHUB="false"
NEXT_PUBLIC_LOGIN_WITH_FACEBOOK="false"

# Required for Hasura to use Firebase
# Replace XXX with your project-id

HASURA_GRAPHQL_JWT_SECRET={ "type": "RS256", "audience": "XXX", "issuer": "https://securetoken.google.com/XXX", "jwk_url": "https://www.googleapis.com/service_accounts/v1/jwk/[email protected]" }
