Encryption - Encryption is the process of translating plain data into encoded data.Nonetheless, uglification may enhance performance but it will unfortunately reduce readability for other collaborators. Essentially, to “uglify” a JavaScript file is to minimize it using this library. In fact, Uglify is a type of Javascript library which helps developers minimize files. Uglification - This is basically the same as minification.Minification differs from all of these, mainly because: These are obfuscation, compression, encryption, and uglification. How is Minification Different from Other Tactics?Įxperienced developers are aware that there are other refinement techniques to improve the efficiency of Javascript source code. Overall, minification can lead to faster webpage loading times, which can improve your website experience, making both search engines and visitors content. These changes may seem minute, but they can significantly impact the efficiency of your Javascript source code. Lines 4,5, and 8 have been consolidated for refinement.Line 7 has been removed because it contains no characters.The character ( }) on line 6 has been removed.The comments on line 1-3 are unnecessary and have been removed for refinement.Here are all of the changes that have been made: It’s presently only eight lines of source code:Īfter the source code has been minimized, here is what it now looks like:Īs you can see, the code now has one line. To help you understand the concept, below is a block of code before minification. By removing extraneous semicolons, comments, whitespace, along with using shorter variable functions and names, developers can create a more compact file size. Think of minification as refining Javascript code. It involves truncating all unnecessary characters of Javascript source code without impacting its usefulness and functionality. Minification, also known as minimization, is a very simple website development concept.

We recommend minifying any JS files that are 4096 bytes or larger in size. You can create a build process that uses these tools to minify and rename the development files and save them to a production directory. Several tools are freely available to minify JavaScript, including the Closure Compiler, JSMin or the YUI Compressor. Thirdly, smaller files can be loaded and run more quickly by web browsers. Secondly, minification can further enhance compression of external JS files and of HTML files in which the JS code is inlined. First, for inline JavaScript and external files that you don't want cached, the smaller file size reduces the network latency incurred each time the page is downloaded. Keeping JavaScript code compact has a number of benefits. "Minifying" code refers to eliminating unnecessary bytes, such as extra spaces, line breaks, and indentation. Use efficient CSS selectors (deprecated).Specify a viewport for mobile browsers (deprecated).Specify a Vary: Accept-Encoding header (deprecated).Serve static content from a cookieless domain (deprecated).Remove query strings from static resources (deprecated). Parallelize downloads across hostnames (deprecated).Optimize the order of styles and scripts (deprecated).Make landing page redirects cacheable (deprecated).Improve server response time (deprecated).Defer loading of JavaScript (deprecated).Combine external JavaScript (deprecated).Avoid Flash on mobile webpages (deprecated).Avoid CSS Avoid CSS expressions (deprecated).Use passive listeners to improve scrolling performance.Use explicit width and height on image elements.Serve static assets with an efficient cache policy.Replace large JavaScript libraries with smaller alternatives (deprecated).Remove duplicate modules in JavaScript bundles.Lazy load third-party resources with facades.
