Getting Started 👔

You should create project. Choose project name and mark project type as SSG.

hpx create

You should move into project folder after this.

cd PROJECT_NAME/src

Development 🛠

Let's launch project.

nim c -r main

Also you can use flags -d:httpx and -d:micro to use alternative HTTP servers.

Let's change main.nim. For it you should open src/ folder and open main.nim file. You will see 👀

import happyx

serve("127.0.0.1", 5000):
  get "/":
    "Hello, world!"

Rewrite this 👨‍🔬

import happyx

# Go to http://127.0.0.1:5000/ 👨‍🔬
serve("127.0.0.1", 5000):
  # Assignment counter
  var counter = 0

  # You can open / in your browser and see result 🍍
  get "/":
    inc counter
    # Return string
    "counter = {counter}"

  # You can open /upd or /upd100 in your browser and see result 🍍
  get "/upd{i?:int}":
    counter += i
    "counter = {counter}"

And recompile 🛠

That's all! Good Luck! 🙂
