Questions about JS Minifier
Common questions about minified scripts and build processes.
Does this replace a bundler?
No. It is intended for simple scripts or quick tests. For large applications, a build pipeline with proper tooling is recommended.
Can it break complex JavaScript?
The tool applies basic minification. If the code depends on very specific formatting or complex expressions, you should always review the output.
Should I edit the minified file?
No. You should edit the source file and regenerate the minified version when you publish changes.
