Websites are becoming increasingly heavy and complex over the years. They represent an important part of the digital environmental footprint. The objective of this project is to detect smells in a website source code that can have a negative ecological impact: overconsumption of energy, "fatware", shortening of the life span of devices, etc. This project is part of ecoCode.

Rules in this repository are mainly based from book 115 Web Ecodesign Best Practices. This reference is maintained by CNumR, a french collective that works for a responsible design of digital services. You can find all applicable rules in the RULES.md file.

🌿 SonarQube plugin

ecoCode JavaScript is an "eco-responsibility" static code analyzer for projects based on the JavaScript ecosystem. It can handle JavaScript, TypeScript and all frameworks that use them. Its main purpose is to work with website source code, but it can also analyze back-end code.

This project proposes rules for the following technologies:

• JavaScript
• TypeScript
• NestJS
• React (JSX)
• React Native / Expo

🔧 ESLint plugin

This project uses an internal ESLint plugin to analyze your source code.

If you are not using SonarQube, we have a solution for you: the linter is working nicely on its own!
Follow instructions in the dedicated README file to use it as a standalone plugin.

🛒 Distribution

The plugin is available from the official SonarQube marketplace! Check the version matrix here.

Ready to use binaries for SonarQube are also available from GitHub.
Make sure to place the binary inside extensions/plugins/ folder of your SonarQube instance.

The standalone version of the ESLint plugin is available from npmjs.

🧩 Compatibility

Plugins Version	SonarQube version	ESLint version
