![]() The content of the individual files have been bundled/combined into the same response, but the content of the files remains the same - so the overall file size is exactly the same as before the bundling. The browser now has to send fewer requests to the server. Below is an updated version of the above sample that takes advantage of this new bundling functionality (making only one request for the JavaScript and one request for the CSS): This causes the browser to request a lot fewer files and in turn reduces the time it takes to fetch them. Each file is currently requested separately by the browser and returned by the server, and the process can take a significant amount of time proportional to the number of files in question.ĪSP.NET is adding a feature that makes it easy to “bundle” or “combine” multiple CSS and JavaScript files into fewer HTTP requests. As shown below, the website consists of 5 CSS and 4 JavaScript files which the browser has to download. Multiple JavaScript and CSS files require multiple HTTP requests from a browser – which in turn can slow down the performance load time.īelow I’ve opened a local website in IE9 and recorded the network traffic using IE’s built-in F12 developer tools. ![]() While this is a good practice from a coding point of view, it often has some unfortunate consequences for the overall performance of the website. Most websites today are made up of multiple JavaScript and CSS files to separate the concerns and keep the code base tight. Even with powerful desktop machines, the load time of your site and perceived performance can make an enormous customer perception. If your site/app loads slowly like that, you are likely losing potential customers because of bad performance. We’ve all tried loading sites on our smartphones – only to eventually give up in frustration as it loads slowly over a slow cellular network. Basics of Bundling and MinificationĪs more and more people use mobile devices to surf the web, it is becoming increasingly important that the websites and apps we build perform well with them. This feature can be used by all ASP.NET applications, including both ASP.NET MVC and ASP.NET Web Forms solutions. ![]() Today’s post covers some of the work we are doing to add built-in support for bundling and minification into ASP.NET - which makes it easy to improve the performance of applications. With ASP.NET 4.5 you'll see a bunch of really nice improvements with both Web Forms and MVC - as well as in the core ASP.NET base foundation that both are built upon. NET and Visual Studio include a ton of great new features and capabilities. Use import init, )) Īll Cfg fields are available as snake_case properties on the object provided as the second argument if any are not set, they default to false.This is the sixth in a series of blog posts I'm doing on ASP.NET 4.5. Rust Get minify-html = "0.15.0" UseĬheck out the docs for API and usage examples. To quickly parallel process a batch of files in place: minhtml -keep-closing-tags -minify-css /path/to/**/*.html minhtml -output /path/to/ -keep-closing-tags -minify-css /path/to/src.html If you have Cargo installed, you can also build and install from source: cargo install minhtml. You can download them in the GitHub release. Precompiled binaries are available for Linux (ARM64 and 圆4), macOS (ARM64 and 圆4), and Windows (圆4). The onepass variant is even more optimised for speed.
