Here's how BundleConfig works:Bundle Registration: In the BundleConfig class, you define bundles by combining multiple CSS or JavaScript files into logical groups. These bundles can represent common sets of files used across your application, such as libraries (e.g., jQuery, Bootstrap) or custom scripts and styles.Minification and Optimization: Along with combining files, you can also specify whether to enable minification and/or optimization for the bundled files. Minification removes unnecessary characters (such as whitespace and comments) from the files to reduce their size, while optimization applies additional optimizations, such as combining and reordering script references.Bundle Rendering in Views: Once bundles are defined in BundleConfig, you can reference them in your views using the @Scripts.Render() and @Styles.Render() helper methods. These methods generate HTML markup to include the bundled files in your page.Conditional Bundling: Bundles can be conditionally enabled or disabled based on whether the application is running in debug or release mode. In debug mode, bundles may be disabled to allow easier debugging of individual files, while in release mode, bundles are typically enabled for improved performance.Here's an example of how BundleConfig might be configured:// App_Start\BundleConfig.csusing System.Web.Optimization;public class BundleConfig {public static void RegisterBundles(BundleCollection bundles){// Define bundlesbundles.Add(new ScriptBundle("~/bundles/jquery").Include("~/Scripts/jquery-{version}.js"));bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include("~/Scripts/bootstrap.js","~/Scripts/respond.js"));bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/bootstrap.css","~/Content/site.css"));// Enable minification and optimizationBundleTable.EnableOptimizations = true;} }
Bundling with MinificationMVC 4 introduced bundling and minification strategies to speed up request load time. Thanks to bundling, we can load several static files from the server with a single HTTP request.
MinificationMinification technique optimizes script or CSS file size by removing unnecessary white space and comments and shortening variable names to one character.
Bundle TypesMVC 5 includes following bundle classes in System.web.Optimization namespace:
ScriptBundle: ScriptBundle is responsible for JavaScript minification of single or multiple script files.
StyleBundle: StyleBundle is responsible for CSS minification of single or multiple style sheet files.
DynamicFolderBundle: Represents a Bundle object that ASP.NET creates from a folder that contains files of the same type.
In order to use Bundle.config in Asp.net MVC4, you will need to create a file called bundle.config in your nyt sudoku project’s root directory. This file contains the settings for your web application.
Bundle.config is a file created in default by MVC that is used to write the bundling code. When the individual request is sent to the server when the user references different files, there occurs unnecessary server overload. Bundling allows the developer to create a bundle of all the javascript and CSS files in the application. With this, all the files are fetched using a single request which improves the performance. Also, the bundles in the bundle.config files are minified. That is, all the extra space, the unnecessary comment is removed and scoped variable names are shortened to minimize the file size. Using the bundle and the minified files in the bundle.config files, it makes the job for a developer easy by referencing a set of files using a single request and thereby making the code clean and readable.
it is used to register the bundles by the bundling and minification system. Many bundles are added by default including jQuery libraries like - jquery.validate, Modernizr, and default CSS references.
