An awesome language minifier for Deno that is powered by WebAssembly!

Language Object

To specify your language easier, you can use the Language object that is exported from the library. Here is an example of passing in your language into the minify function:

const code = `
html {
  margin: 0;
  padding: 0;
}`;

minify(Language.CSS, code);

Minifying Code

To minify any given code, simply use the minify function and pass in the given language as your first argument and the code as the second. The language that you need to pass in can either be the Language variant discussed later on, or the actual lowercase string that is your language name. Here are two examples of us minifying some CSS code:

const code = `
html {
  margin: 0;
  padding: 0;
}`;

// both return the minifed CSS
minify(Language.CSS, code);
minify("css", code);

Minifying HTML

As us HTML programmers know, you can include CSS and JS inside of your HTML code. If you want to minify the CSS/JS in your HTML, the just use the minifyHTML function! You just pass in the code first and the options for whether you want to minify CSS and/or JS second. Here is an example:

const code = `
<html>
<head>
  <style>
    html {
      margin: 0;
      padding: 0;
    }
  </style>
  <script>
    const x = 23;
    if (x > 20) {
      x--;
    }
    console.log(x);
  </script>
</head>
</html>
`;

// returns the minified HTML code with the CSS and JS code properly minified, too
minifyHTML(code, {
  minifyCSS: true,
  minifyJS: true,
});

Supported Languages

The following languages are supported for minification. You can either pass in the Language object variant into our various functions to specify your language or the actual string in parentheses to pick your language.

  • HTML ("html")

  • CSS ("css")

  • JS ("js")

  • JSON ("json")

Building

To build the project, make sure that you have the Go compiler and Cargo installed. After that, you can just run the deno run -A build.ts to generate the corresponding files.
