How to apply Google Closure to my entire web page?

Question

Google has the very nice JavaScript compressor called "Closure"

http://closure-compiler.appspot.com/home

But it's a pain to use for inline JavaScript within an HTML file.

Question: Does an online tool exist where I simply give the input "uncompress.html" and it spits out the compressed version of that HTML with all inline JavaScript compressed as well?

Answer 1

Minifiers,obfuscators and compressors have been designed to solve the issue of downloading external elements when loading a page. They were never meant to be used for inline JavaScript or CSS since lots of that is normally kept outside of the page in a separate file.

Since you should be gzipping as much as you can, for browsers that can handle gzip, it shouldn't in reality matter that your inline css/javascript isn't minified on the page.

Answer 2

If you use PHP, you might call the compiler of google in this way, and then use the header to return javascript

<?php
    $script = file_get_contents('http://www.domain.com/scripts/script.js');
    $ch = curl_init('http://closure-compiler.appspot.com/compile');

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'output_info=compiled_code&output_format=text&compilation_level=SIMPLE_OPTIMIZATIONS&js_code=' . urlencode($script));
    $output = curl_exec($ch);
    curl_close($ch);

    header('Content-type: application/javascript');
    echo $output;

?>
