Parses CSS media query expressions.
Install via npm:
$ npm install css-mq-parser
This package exports one function, which can parse CSS media query expressions and return an AST.
The parser tolerates several known CSS media query browser hacks, but will throw a SyntaxError
if the media query expression is severely malformed.
Note that this module implements a lax/liberal/non-validating parser; even modulo browser hacks, the fact that it parses a given expression successfully does not guarantee that the expression is valid per the relevant CSS specifications.
var parseMediaQuery = require('css-mq-parser');
var ast = parseMediaQuery('screen and (min-width: 48em)');
The ast
variable will have the following payload:
[
{
"inverse": false,
"preTypeHack": "",
"type": "screen",
"postTypeHack": "",
"expressions": [
{
"modifier": "min",
"feature": "width",
"value": "48em"
}
]
}
]
