LESS happens to be written in JavaScript, so installing it can be as easy as downloading the official less.js JavaScript library, linking it to our /Views/Home/Index.cshtml page, and letting its magic work without having to set up anything else.

Should we do that, then? Not a chance. As we said earlier, delegating the compilation task on the client side will be highly inefficient, especially in a client-intensive Angular-based SPA. Not to mention the fact that we already have Webpack that will automatically compile, optimize, and pack all our CSS classes together in a single file.

Given our scenario, the best thing we can possibly do without changing our current Angular files and Webpack configuration is the following:

1. Install the aforementioned LESS Compiler extension tool and configure it to automatically build LESS files.
2. Rename all our existing CSS files with LESS files with the same name, as CSS files are also LESS files.
3. Update the existing code to take full advantage of the features and syntax provided by LESS.

That's it, we won't have to change anything in Angular, as our components will always point to the compiled file, the one ending with the .css prefix. We also don't have to worry about minify, uglify, and/or merge these files, as these tasks are already handled by Webpack using our current configuration.

That said, let's get to work.
