Live Code Metrics is a VS Code extension that provides real-time analysis of function sizes in your code. Supporting JavaScript, TypeScript, Java, and Python, it helps maintain clean and maintainable code by visualizing function lengths against customizable thresholds.
Real-time Function Analysis: Automatically detects and displays functions, methods, and classes in your open files.
Line Count Visualization: Shows the number of lines for each code section, along with its name and location in the file.
Progress Bar: Visual representation of how close each function is to the maximum line threshold.
Customizable Threshold: Set your own maximum line count to suit your team's coding standards.
Why having small pieces of code matters
Maintaining smaller, focused functions in your codebase offers numerous benefits:
Improved Readability: Shorter functions are easier to read and understand at a glance.
Enhanced Maintainability: Smaller code units are easier to modify, test, and debug.
Better Code Organization: Encourages breaking down complex logic into manageable pieces.
Reduced Cognitive Load: Developers can focus on one specific task or concept at a time.
Easier Collaboration: Smaller functions lead to fewer merge conflicts and easier code reviews.
Increased Reusability: Well-defined, focused functions are more likely to be reusable in other parts of your codebase.
By using the Live Code Metrics extension, you're taking a proactive step towards writing cleaner, more efficient code.
