A quick and simple took to find all script src's in a given HTML document. Under the hood we simple-html-tokenizer to parse the document.
yarn add find-script-srcs-in-documentconst allScriptSources = require('find-script-srcs-in-document');
// basic
allScriptSources('<html><script src="foo"></scripts>') === ['foo'];
// with the ability to ignore on a specific attribute
allScriptSources('<html><script src="foo" data-ignore-me></scripts>', allScriptSources.ignoreWithAttribute('data-ignore-me')) === [];
// advanced
allScriptSources('<html><script src="foo" data-ignore-me></scripts>', scriptToken => {
const {
type, // string type (StartTag)
tagName, // string tagName (script)
attributes, // array of attributes
selfClosing // boolean
} = scriptToken;
return attributes.find(attribute => attribute[0] === 'data-ignore-me')
})) === [];
