Welcome to the fascinating world of Elm, a functional programming language that brings clarity and simplicity to web development! In this blog, we will explore how to quickly render HTML in Elm, showcasing its features with handy examples.

Getting Started with Elm HTML

The HTML part of an Elm program is straightforward and succinct, making it user-friendly even for beginners. Let’s break down some Elm code that demonstrates how to build a simple HTML interface.

elm
import Html exposing (Html, button, div, text)
import Html.Events exposing (onClick)

type Msg = Increment | Decrement

view : Int -> Html Msg
view count = 
    div [] 
        [ button [ onClick Decrement ] [ text "-" ]
        , div [] [ text (String.fromInt count) ]
        , button [ onClick Increment ] [ text "+" ]
        ]

Understanding the Code: An Analogy

Think of the Elm program as a cooking recipe. Each ingredient represents an element in your user interface — like buttons and text — and the final dish is what users interact with. Here’s how it works:

• Ingredients (Imports): In our recipe, we import necessary ingredients from the Elm library, including Html for HTML elements and Html.Events for handling events.
• Recipe Steps (Type and View): We define two main actions you can take: increment and decrement. The view function defines how these actions affect what you see — much like how mixing ingredients changes the taste of the dish.
• The Final Dish (Output): When you call view 42, you create an interface that allows users to increase or decrease the number displayed. It’s like presenting your finished meal to the guests!
