Show HN: Nex – The simplest way to build Htmx apps in Elixir

  I've been building web apps for years, and I got tired of the complexity. So I created Nex – a minimalist web framework that strips away the cruft and lets you ship features fast.

  *What makes Nex different:*

  - *Zero JavaScript complexity* – Server-side rendering with HTMX, no React/Vue needed - *File-based routing* – Drop a file in `src/pages/`, get a route automatically - *Hot reload* – Instant feedback while developing - *Real-time ready* – Built-in Server-Sent Events for live dashboards, chat, streaming - *Production-ready* – Docker included, deploy to Railway/Fly.io in minutes

  *Who it's for:*

  Indie hackers, startups, and anyone building internal tools, dashboards, or real-time apps. Not for enterprise complexity – that's what Phoenix is for.

  *Quick example:*

  ```elixir defmodule MyApp.Pages.Todos do use Nex.Page

    def mount(_params) do
      %{todos: fetch_todos()}
    end
  
    def render(assigns) do
      ~H"""
      <h1>My Todos</h1>
      <form hx-post="/add_todo" hx-target="#todos">
        <input type="text" name="title" required />
        <button>Add</button>
      </form>
      <ul id="todos">
        <li :for={todo <- @todos}>{todo.title}</li>
      </ul>
      """
    end
  
    def add_todo(%{"title" => title}) do
      todo = create_todo(title)
      ~H"<li>{@todo.title}</li>"
    end

  end ```

  *Get started:*

  ```bash mix archive.install hex nex_new mix nex.new my_app cd my_app mix nex.dev ```

  Check out the examples (chatbot with streaming, guestbook, dynamic routes) to see what's possible.

  I'd love feedback from the community – what would make this more useful for your projects?
