(also code minification or file minimization)
Minification, also called code minification or file minimization, expunges all superfluous characters from a source code without affecting its operational capacity. This typically entails the removal of spaces, line breaks, comments, and in some instances, the abbreviation of variable names.
- CSS minification: Similarly, CSS files can be minified for the same purpose.
- HTML minification: HTML files can also be minified, eliminating unnecessary spaces, line breaks, and comments to enhance website performance.
Pros and cons of minification
- Performance: Minification improves website loading speed by reducing the size of the source code, enhancing user experience.
- Bandwidth reduction: By minimizing the size of files, minification saves bandwidth.
- Readability: Minified code is harder to read and debug because it lacks the usual formatting and comments that provide context.
- Maintenance: Changes or updates to the code require the minified file to be generated again, which can be a time-consuming process if not automated.
- Use minification as part of your build process to ensure your production code is as compact as possible.
- Always keep a copy of the pre-minified files for debugging and development.
