Mensch
A non-validating CSS parser with comment support and flexible AST representation.
What is Mensch?
Mensch is a CSS parser for Node.js that converts CSS strings into abstract syntax trees (ASTs) and back. It focuses on handling major language constructs while recovering from common syntax errors like mismatched braces and missing semicolons. The parser is non-validating, meaning it does not check for invalid property names or rule placement.
Node.js developers who need to parse, manipulate, or analyze CSS programmatically, such as those building CSS preprocessors, linters, or email template editors. It is also suitable for projects requiring robust error recovery and comment preservation in CSS processing.
Developers choose Mensch for its graceful error recovery from syntax errors and its ability to preserve comments in the AST—a feature uncommon in most CSS parsers. It also provides lexical tokenization and position tracking for advanced use cases.
