Explore Angular 4 - Retrieve the guidelines based on their titles within the scss document

I am in search of a reliable method to extract a rule by class selector from a .scss file in order to display it on the Angular app ui. So far, I have not been able to find a suitable parser for .scss that can be used specifically for retrieving a class rule by its name.

For example: If I specify the class selector as 'custom-class', I simply need the content within the curly brackets.

.custom-class {
   width: 334px;
   text-decoration: underline;
}

Are there any typings available for scss that could be utilized? Or are there any npm packages out there where I can input the file path and the class name for which the rule content should be extracted from the scss file?

One such package is https://www.npmjs.com/package/list-css-selectors which can list the class selectors, however, it works for css files and not for fetching class content from scss files.

Answer №1

It is not possible to access .scss files during the application runtime as they are converted into css files. One way to obtain necessary classes is by listing all style sheets loaded by the browser.

for (let i = 0; i < document.styleSheets.length; i++) {
  const sheet = document.styleSheets[i];
  if (sheet['cssRules']) {
    for (const rule of sheet['cssRules']) {
      const cssText = rule['cssText'] as string;
      if (cssText.startsWith('.my-class')) {
        console.log(cssText);
      }
    }
  }
}
// Output in console:
// .my-class { color: rgb(51, 51, 51); }
