Installation

First you should install Nim language which is an elegant and high performance language. Follow the instructions and set environment variables correctly.

Then you can use nimble command to install prologue.

nimble install prologue

Chronos Backend

Prologue can use chronos instead of asyncdispatch via the kairos HTTP server:

requires "prologue[kairos]"

Or without nimble, pass -d:asyncBackend=chronos to the compiler. No code changes needed — your handlers work with both backends.

Usages

Hello World

import prologue

proc hello*(ctx: Context) {.async.} =
  resp "<h1>Hello, Prologue!</h1>"

let app = newApp()
app.get("/", hello)
app.run()

Run app.nim ( nim c -r app.nim ). Now the server is running at localhost:8080.
