What is Open Food Facts?

A food products database

Open Food Facts is a database of food products with ingredients, allergens, nutrition facts… which allow us to compute scores like Nutri-Score, NOVA groups and Eco-Score.

Made by everyone

Open Food Facts is a non-profit association of volunteers. 25000+ contributors like you have added 1,7M+ products from 150 countries using our Android or iPhone apps to scan barcodes and upload pictures of products and their labels.

For everyone

Data about food is of public interest and has to be open. The complete database is published as open data and can be reused by anyone.

Ongoing documentation of user flows

Visual documentation of the App on Figma

Documentation of the source code

The documentation is generated automatically from the source code and your improvements to code documentation are published automatically. Code documentation on GitHub pages

Installation

Choose the right flavor Install steps
* Download the latest Android Studio stable build.
* If you are running the app for the first time, Android Studio will ask you to install the Gradle dependencies.
* If you are a new contributor to open-source, we recommend you read our Setup Guidelines
* In Android Studio, make sure to select OFF as the default flavor for Open Food Facts (OBF is Open Beauty Facts, OPF - Open Products Facts, OPFF - Open Pet Food Facts)
* You should be able to install Open Food Facts on your phone using an USB cable, or run it in an emulator.
* The package name on the Play Store is org.openfoodfacts.scanner. For historic reasons, it's openfoodfacts.github.scrachx.openfood in the code and on F-Droid.

Running a Fastlane lane

The project uses Fastlane to automate release and screenshots generation.

  • First time you checkout, run bundle install at the root of the project
  • Then launch lanes using bundle exec fastlane release (for example the release lane)

Libraries we use

We use the following libraries, and we're not closed to changes where relevant :-) If you spot any libraries we added or we don't use anymore, feel free to update this list using a Pull Request.

  • Dagger 2 - A fast dependency injector for Android and Java
  • Retrofit - Retrofit turns your REST API into a Java interface
  • OkHttp - An HTTP+SPDY client for Android and Java applications
  • Mockito - Most popular Mocking framework for unit tests written in Java
  • Apache - The Apache Commons IO library contains utility classes, stream implementations, file filters, file comparators, endian transformation classes, and much more.
  • Kotlin Coroutines - A coroutine is a concurrency design pattern that you can use on Android to simplify code that executes asynchronously.
  • Hilt - Hilt is a dependency injection library for Android that reduces the boilerplate of doing manual dependency injection in your project.
  • Dagger - Manual dependency injection or service locators in an Android app can be problematic depending on the size of your project. You can limit your project's complexity as it scales up by using Dagger to manage dependencies. Dagger automatically generates code that mimics the code you would otherwise have hand-written.
  • Jackson - Core part of Jackson that defines Streaming API as well as basic shared abstractions
  • journeyapps/zxing-android-embedded - Barcode scanner library for Android, based on the ZXing decoder
  • GreenDao
  • mikepenz/MaterialDrawer - The flexible, easy to use, all in one drawer library for your Android project.

Big thanks to their contributors!
