How to Check Magento 2 Coding Standards: A Complete Guide

 Ensuring that your Magento 2 code adheres to coding standards is crucial for maintaining code quality, improving readability, and preventing errors. Magento 2 follows PHP coding standards based on PSR-1, PSR-2, and Magento-specific best practices. In this guide, we'll walk you through effectively checking Magento 2 coding standards.

Methods to Check Magento 2 Coding Standards

1. Use PHP CodeSniffer with Magento Coding Standard

Magento provides a set of rules and guidelines that can be checked using a PHP CodeSniffer tool. First, you must install PHP CodeSniffer and Magento's coding standard package. Once installed, you must register the Magento coding standard with PHP CodeSniffer.

After registration, you can run a command to analyze your code. The tool will scan the codebase and highlight any violations that need to be addressed.

2. Auto-Fix Issues with PHP Code Beautifier and Fixer

Some formatting issues detected by PHP CodeSniffer can be fixed automatically using PHP Code Beautifier and Fixer. Running the tool will apply corrections to make your code compliant with Magento 2 coding standards.

3. Using Magento’s Built-in Coding Standards Tool

Magento provides a built-in tool for performing static code analysis. Running this tool in the command line will check your code for standard compliance along with other static tests. This is a quick way to ensure your code meets Magento’s requirements.

4. Integrating with CI/CD Pipelines

To enforce coding standards in a continuous integration environment, you can integrate PHP CodeSniffer with your CI/CD pipeline. Many CI/CD platforms, such as GitHub Actions, GitLab CI/CD, and Jenkins, allow you to automate code checks during development. This ensures that every new code commit adheres to Magento’s best practices before being deployed.

Conclusion

Checking and enforcing Magento 2 coding standards ensures your code is clean, secure, and compatible with Magento updates. By using PHP CodeSniffer, Magento's built-in tools, and automated CI/CD checks, you can maintain high-quality code across your projects.
