Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Add CSS Parser Algorithms to your project:
npm install @csstools/css-parser-algorithms @csstools/css-tokenizer --save-dev
CSS Parser Algorithms only accepts tokenized CSS.
It must be used together with @csstools/css-tokenizer
.
import { tokenizer, TokenType } from '@csstools/css-tokenizer';
import { parseComponentValue } from '@csstools/css-parser-algorithms';
const myCSS = `@media only screen and (min-width: 768rem) {
.foo {
content: 'Some content!' !important;
}
}
`;
const t = tokenizer({
css: myCSS,
});
const tokens = [];
{
while (!t.endOfFile()) {
tokens.push(t.nextToken());
}
tokens.push(t.nextToken()); // EOF-token
}
const options = {
onParseError: ((err) => {
throw err;
}),
};
const result = parseComponentValue(tokens, options);
console.log(result);
gatherNodeAncestry
The AST does not expose the entire ancestry of each node. The walker methods do provide access to the current parent, but also not the entire ancestry.
To gather the entire ancestry for a a given sub tree of the AST you can use gatherNodeAncestry
.
The result is a Map
with the child nodes as keys and the parents as values.
This allows you to lookup any ancestor of any node.
import { parseComponentValue } from '@csstools/css-parser-algorithms';
const result = parseComponentValue(tokens, options);
const ancestry = gatherNodeAncestry(result);
{
onParseError?: (error: ParseError) => void
}
onParseError
The parser algorithms are forgiving and won't stop when a parse error is encountered. Parse errors also aren't tokens.
To receive parsing error information you can set a callback.
Parser errors will try to inform you about the point in the parsing logic the error happened. This tells you the kind of error.
