Eastar is a pure-Elixir implementation of A* graph pathfinding algorithm.
All graph environment, like nodes connectivity, distance & H-metric are abstracted away - you provide them as functions.
Reprise reloads your modules after they've been recompiled.
It is thought as a companion to inotify tools. It scans for changes in beam files belonging to youyr project. Doesn't recompile stuff by itself.
WebAssembly is a web DSL for Elixir.
You create html structure straight using do blocks. Means, you can intermix html-building blocks with full Elixir syntax.
DSL output is an iolist, which you can flatten to string, but better use is to just feed it to the socket (via Plug & Cowboy).
