VultureCSS Core

Remove dead css from your stylesheets

VultureCSS Core analyze the HTML code and the CSS code and remove all the unused CSS code. All this, of course, will be done without changing the websites' appearance. It can be used via JAR file or via API.

The current version is 0.2.11 BETA.

Usage

Command line

java -jar VultureCSSCore.jar -css style.css -html index.html -out style.min.css
java -jar VultureCSSCore.jar -css https://example.com/style.css -html https://example.com

Or include the library inside your project

URL htmlUrl = new URL("https://dotmaui.com");
URL cssUrl = new URL("https://dotmaui.com/style.css");
VultureCSSCore v = new VultureCSSCore(cssUrl, htmlUrl);
List<Carcass> carcasses = v.Process();

carcasses.forEach((c) -> {
    System.out.println(c.getUsedCSS());
});

Or specify only one HTML page, all included CSS files will be processed.

java -jar VultureCSSCore.jar -html https://dotmaui.com

URL url = new URL("https://dotmaui.com");
VultureCSSCore v = new VultureCSSCore();
v.setHtmlUrl(url);
List<Carcass> carcasses = v.Process();

carcasses.forEach((c) -> {
    System.out.println(c.getUsedCSS());
});

-html https://api.dotmaui.com -css https://api.dotmaui.com/static/djmaui/css/style.min.css -cdn -apikey DOTMAUI_APIKEY

URL url = new URL("https://dotmaui.com");

VultureCSSOptions opt = new VultureCSSOptions();
opt.setCdnMode(true);
opt.setDotMauiApiKey("YOUR_API_KEY");

VultureCSSCore v = new VultureCSSCore();
v.setHtmlUrl(url);
v.setOptions(opt);

List<Carcass> carcasses = v.Process();

carcasses.forEach((c) -> {
    System.out.println(c.getCdnUrl());
});

Merge and optimize CSS from urls

List<String> urls = new ArrayList<>();
urls.add("https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css");
urls.add("https://dotmaui.com/assets/css/production/dotmaui.com_app_min.css?v=2");

String result = VultureCSSCore.mergeAndOptimizeCSSFromUrls(urls);

System.out.println(result);
