One of my favorite uses of Nu is for building web apps and APIs for mobile apps. To support that, I've evolved a collection of frameworks that support serving and making HTTP requests, generating markup, serializing data, and accessing databases. To keep things flexible, each framework can be built separately and is in a separate git repository. But to make them simple to use, I've created a binary installer that installs my favorite components from a single package.
