Minification can improve performance. Node’s V8 optimizing compiler inlines functions according to some heuristics. Minification influences these heuristics. This can cause inlining of previously not inlined functions. Since inlined functions generally perform faster, this can lead to performance improvements. ###Node 9.0+ / V8 6.2+ (Turbofan) – minor performance improvements If the function’s unoptimized bytecode size … Read more
Concatenation is just appending all of the static files into one large file. Minification is just removing unnecesary whitespace and redundant / optional tokens like curlys and semicolons, and can be reversed by using a linter. Uglification is the act of transforming the code into an “unreadable” form, that is, renaming variables/functions to hide the … Read more
What you want to do is parse the source maps. This has nothing to do with web browsers. All you need to do is translate the minified reference into the unminified resource. If you have any experience with NodeJS there is already a package that does this for you. https://github.com/mozilla/source-map/ To install the library npm … Read more
I ran into this problem before with Grunt.js Uglify plugin. One of the options are mangle uglify: { options: { mangle: false }, Which I believe runs regex functions on “like strings” and minifys them. For example: angular.module(“imgur”, [“imgur.global”,”imgur.album”]); Would become: angular.module(“a”, [“a.global”,”a.album”]); Disable it — this feature doesn’t play nice with Angular. Edit: To … Read more
If you’re on unix – gzip -c filename.min.js | wc -c will give you a byte count of the gzipped file
concat.js is being included in the concat task’s source files public/js/*.js. You could have a task that removes concat.js (if the file exists) before concatenating again, pass an array to explicitly define which files you want to concatenate and their order, or change the structure of your project. If doing the latter, you could put … Read more
Perhaps try HTML Compressor, here’s a before and after table showing what it can do (including for Stack Overflow itself): It features many selections for optimizing your pages up to and including script minimizing (ompressor, Google Closure Compiler, your own compressor) where it would be safe. The default option set is quite conservative, so you … Read more
Assuming this problem still has not be resolved, a lot of individual files don’t end their code with a semicolon. Most jQuery scripts end with (jQuery) and you need to have (jQuery);. As separate files the script will load just fine but as one individual file you need the semicolons.
PHP is compiled into bytecode, which is then interpreted on top of something resembling a VM. Many other scripting languages follow the same general process, including Perl and Ruby. It’s not really a traditional interpreted language like, say, BASIC. There would be no effective speed increase if you attempted to “minify” the source. You would … Read more
The TypeScript compiler does not support the generation of minifies or obfuscated code. you will need to use another tool against the JavaScript output of the compiler. There’s an open feature request: microsoft/TypeScript#8
