Frequently Asked Questions
How does Terser-powered minification improve app performance?
Terser is the industry standard for JS compression. It performs deep structural analysis to not only remove whitespace and comments but also to shorten variable names (mangling) and inline constants. This drastically reduces the JavaScript bundle size, leading to faster execution and lower data costs for mobile users.
What is the risk of enabling "Mangle" mode?
Mangle mode is generally safe but can occasionally break code that relies on function names as strings (like some older dependency injection patterns). However, for modern ES6+ applications and React/Next.js projects, Mangle is highly recommended as it provides the most significant byte reduction.
Is my source code uploaded for minification?
No. All JavaScript minification occurs locally in your browser's memory. Your intellectual property and sensitive logic never leave your machine, ensuring complete privacy and high-speed processing without network lag.
