Pros
Pro Concatenates scripts and styles and auto-generates matching source maps
Brunch automatically produces a source map for all javascript files and CSS stylesheets whenever it minifies an app's resources. This little feature is extremely helpful when debugging is required at the client end.
Pro Time to setup is extremely low
After installing Brunch the next step is to load a skeleton from git.io/skeletons. This step is as easy as installing another plugin from the npm registry, just point Brunch to the path of the required skeleton/generator then wait for it to work out its magic. Next, run brunch build
then wait for a second or two and voila! The project is ready.
Pro Compilation is super fast
According to speed benchmarks, Brunch is one of the fastest tools around for compiling files. According to the authors of Brunch the reason behind this speed is that it recompiles only the changes that were made to an app and performs extensive caching of the app's code.
