gkralik/php-uglifyjs
PHP port of Dean Edwards’ JavaScript Packer for minifying/packing JS. Install via Composer and compress a script with GK\JavascriptPacker->pack(), choosing encoding (0/10/62/95), optional fast decoder, and special chars handling.
| Failure Mode | Impact | Mitigation |
|---|---|---|
| JS Syntax Errors | Crashes or corrupts output | Validate input with json_decode() (JS must be valid JSON). |
| High CPU Load | Server timeouts under load | Cache compressed JS; use queue jobs. |
| Encoding Issues | Broken JS in non-UTF-8 envs | Force UTF-8 encoding in PHP (mb_internal_encoding('UTF-8')). |
| Package Abandonment | No updates/security patches | Fork and maintain; monitor GitHub. |
| ES6+ Incompatibility | Silent failures or broken JS | Transpile with Babel first. |
| XSS Vulnerabilities | Malicious JS injection | Whitelist safe scripts; avoid dynamic input. |
