ema

ema is a WIP next-gen Haskell static site generator that is change-aware. In addition to static site generation, it provides a live server that hot-reload's on code or data change.

The ultimate goal of ema is to make it possible to easily implement your own neuron, 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.

The simplest ema app looks like this:

main :: IO ()
main = do
  let name :: Text = "Ema"
  runEmaPure $
    encodeUtf8 $ "<b>Hello</b>, from " <> name

Quick Preview

If you have Nix installed with Flakes, give Ema a test-drive by running it to serve its own documentation:

PORT=8000 nix run github:srid/ema

NOTE: This will work if you have this repo's ./docs directory locally. In future, ema should be made to include the docs in the nix derivation and reference it.

Hacking

Run bin/run (or Ctrl+Shift+B in VSCode). This runs the clock example; modify ./.ghcid to run a different example.

TODO

  • MVP
  • Implement hot reload, and ditch browser-sync
  • Multi-websocket-client support
  • Static site generation mode
  • add common examples,
    • filesystem watcher
    • docs site for self (w/ breadcrumbs and possibly even search)

pre-announce,

  • CLI UX
    • opts
    • logging
  • How to serve non-generated files (css, img, etc.)
  • Publish Data.LVar to Hackage
  • documentation (howto)
  • Avoid tailwind CDN in docs (use twind or windicss) for better lighthouse score

doc notes,

  • hot reload fast, morphdom
    • html templates + tailwind for fast style feedback
  • use async:race to avoid ghcid ghosts
  • tailwind + blaze-html layout (BlazeWind?) for no-frills getting started
  • dealing with errors
  • messaging re: hakyll
    • safer/ simpler routes system
    • bring your own templates / DSL
  • messaging re: svelte
    • SSE
