Bundle Phobia

Find the cost of adding a npm package to your bundle

BundlePhobia is a web service to find out the how much size will a npm package cost your project. It can measure the size of CSS/Sass libs too and report whether the module supports tree shaking.

The same service is available via cli tool and an atom plugin.

I LOVE bundlephobia. It makes deciding on dependencies much easier and also makes it easier to see the potential impact a library can have on my build. A must-have for any JS dev.
