Package description
The postcss-safe-parser package is a fault-tolerant CSS parser that can handle CSS with syntax errors. It is designed to be used with PostCSS, a tool for transforming CSS with JavaScript plugins. The safe parser can parse CSS files and recover from syntax errors gracefully, allowing developers to work with CSS that may not be perfectly formatted or may contain mistakes.
Fault-tolerant CSS parsing
This feature allows developers to parse CSS with syntax errors without stopping the process. The provided code sample demonstrates how to use postcss-safe-parser with PostCSS to process a CSS string.
const postcss = require('postcss');
const safeParser = require('postcss-safe-parser');
postcss()
.process('a { color: red; }', { parser: safeParser })
.then(result => {
console.log(result.css);
});PostCSS itself is a tool for transforming CSS with JavaScript plugins. While it is not a parser, it uses different parsers like postcss-safe-parser to handle CSS. It is more of an ecosystem than a simple parser and provides a wide range of plugins for various tasks.
css-tree is a CSS parser that also allows for walking and manipulation of the parsed CSS AST (Abstract Syntax Tree). It is similar to postcss-safe-parser in that it can parse CSS, but it does not specifically focus on fault tolerance.
stylelint is a modern linter that helps you avoid errors and enforce conventions in your styles. It uses PostCSS and its parsers for parsing CSS. While not a parser itself, it is related in functionality as it needs to parse CSS to lint it.
gonzales-pe is a CSS parser with a focus on performance and a rich API for traversing and manipulating the parsed CSS. Unlike postcss-safe-parser, it does not emphasize safe parsing of erroneous CSS.
