Veganify

Check if a product is vegan or not with » Veganify.app

Overview

Veganify checks the barcode (EAN or UPC) of a food- or non-food-product and tells you if it is vegan or not. It is an useful tool for vegans and vegetarians - Developed with usability and simplicity in mind, so without distracting irrelevant facts or advertising. Veganify combines the Databases of OpenFoodFacts, OpenBeautyFacts and Open EAN Database, as well as our very own ingredient checker in one tool.

See an example of how it works!

The Veganify Ingredients API checks the products ingredients against a list of thousands of non-vegan items.

Development Guidelines

Note

We're aware not everything in this repo follows those standards. This is because of how the project was started and evolved. We're working on improving this.

Component Structure

• Break down components into smaller, reusable pieces
• Each significant component should have its own directory with the following structure:
  • hooks/ for component-specific hooks
  • utils/ for component-specific utilities
  • models/ for component-specific types
• Small, simple components can be single files

Testing

• All utility functions must have 100% test coverage
• Tests are written using Jest for unit testing
• Components currently don't require test coverage
• Playwright is used for end-to-end testing but currently only coversa few basics use cases. More tests are needed.

TypeScript

• TypeScript is mandatory
• The any type is not acceptable unless absolutely necessary
• Always define proper interfaces and types in the appropriate models folder
• Use type inference when possible

Internationalization

• Use next-intl for translations
• Add new translations to all language files in /locales
• Follow the existing translation key structure

Code Style

• Follow Node.js, React, and Next.js best practices
• Use the App Router pattern for routing
• Keep components pure and functional when possible
• Use hooks for state management and side effects
• Follow the DRY (Don't Repeat Yourself) principle
• Use meaningful variable and function names
• Write comments for complex logic
• Keep functions small and focused

Styling

• Place all styles in the styles folder
• Keep styles modular and scoped to components when possible
• Be sure to use SCSS for styling
• Use CSS variables for theming and repeated values

When making a contribution, please follow these guidelines to ensure consistency and maintainability.

Remember that every contribution, no matter how small, is valuable to the project. Thank you for helping make Veganify better!
