Questions tagged [bundling-and-minification]

Bundling and minification are used to optimize web content by reducing the number of requests to the server and as well as the size of requested assets (such as CSS and JavaScript).

Bundling makes it easy to combine or bundle multiple files into a single file. You can create CSS, JavaScript and other bundles. Fewer files means fewer HTTP requests and that can improve first page load performance.

Minification performs a variety of different code optimizations to scripts or CSS, such as removing unnecessary white space and comments and shortening variable names to one character.
