A lightweight JSON minifier that removes whitespace and comments from JWCC (JSON with Commas and Comments) or HuJSON (Human JSON).
- Removes single-line comments (
//) - Removes multi-line comments (
/* */) - Removes whitespace (
" \t\r\n") - Removes trailing commas before closing brackets and braces
- No RegExp.
- Zero dependencies.
- Fault-tolerant: Invalid JSON is also parsable.
