Ema is a next-gen Haskell library for building jamstack-style static sites. Ema sites are change-aware; in addition to good ol’ static site generation, Ema provides a live server supporting fast hot-reload in the browser, on code or data change.
The ultimate purpose of ema is to facilitate creating with ease your own neuron, 1 or just about any app that creates a browser view of arbitrarily changing data (on disk, database, or whatever). Ema is designed to facilitate creation of apps whose data is normally edited via traditional mechanisms (eg: text editor) but rendered as a delightful web page - so as to provide an economical read-only view of your data on desktop & mobile. A classic static site is just one type of such kind of apps.
