Full-stack, pure Nim. Backend and JS using the same staticly-typed model.

app.nim

import htmlgen
import jester
import data

routes:
  get "/":
    resp(
      html(
        head(
          script(src="/js/js.js")),
        body(
          ul(
            li(db))))
  get "/js/js.js":
    const result = staticExec "nim -d:release js jsclient.nim"
    const clientJS = staticRead "nimcache/jsclient.js"
    resp clientJS

data.nim

const db* = "database"

jsclient.nim

import data

when isMainModule:
  echo db

Makefile

app:
	nim c app.nim

clean:
	rm app

run:
	./app

Both the string on the page and in the console log come from the same source - db.nim.

To run this example, nimble install jester before you make app run.

I used this layout:

 $ tree
.
├── app
├── app.nim
├── data.nim
├── js.nim
├── Makefile
└── public
    └── js
        └── js.js

Updated to statically build the js code into the app using compiletime magic. (ie, staticExec and staticRead)
