Nodejs Javascript Vitest

Code Generation Guidelines

Coding standards

• Use JavaScript with ES2022 features and Node.js (20+) ESM modules
• Use Node.js built-in modules and avoid external dependencies where possible
• Ask the user if you require any additional dependencies before adding them
• Always use async/await for asynchronous code, and use 'node:util' promisify function to avoid callbacks
• Keep the code simple and maintainable
• Use descriptive variable and function names
• Do not add comments unless absolutely necessary, the code should be self-explanatory
• Never use null, always use undefined for optional values
• Prefer functions over classes

Testing

• Use Vitest for testing
• Write tests for all new features and bug fixes
• Ensure tests cover edge cases and error handling
• NEVER change the original code to make it easier to test, instead, write tests that cover the original code as it is

Documentation

• When adding new features or making significant changes, update the README.md file where necessary

User interactions

• Ask questions if you are unsure about the implementation details, design choices, or need clarification on the requirements
• Always answer in the same language as the question, but use english for the generated content like code, comments or docs
