JavaScript Minification compresses JS files by removing unnecessary characters while preserving full functionality.
12.1 Overview #
This process reduces:
- Script size
- Download time
- Parsing and execution time
The logic and behavior of your scripts remain unchanged. Only non-essential characters such as whitespace, comments, and formatting are removed.
Benefits:
- Improved Total Blocking Time (TBT)
- Better Lighthouse performance score
- Faster frontend interactivity
How It Works Internally #
- Scans eligible JavaScript files
- Removes unnecessary characters safely
- Preserves functionality and execution order
- Works with theme and plugin scripts
12.2 Settings #
Enable JavaScript Minification #
- Toggle Enable JS Minification → ON
Once enabled, SpeedyGo automatically minifies eligible JavaScript files before serving them.
12.3 Best Practice Recommendation #
- Test interactive elements after enabling
- Exclude problematic scripts if conflicts occur
- Clear cache after activation for immediate results
JavaScript Minification improves script efficiency and enhances overall performance metrics.
