komodo-react v0.0.1

React bindings for Komodo Elixir library

Installation

• Follow the instructions from the Komodo library to render js components with Phoenix Liveview.

• Add the npm dependency komodo-react as well as react and react-dom in the assets folder, e.g.

npm install --save komodo-react react react-dom --prefix assets

Usage

If we have a React Counter component that we would normally use in React like so

<Counter
  counter={4}
  onIncrement={(amount) => console.log(`Increment by ${amount}`)}
/>

then we can render it from a LiveView with

  def render(assigns) do
    ~H"""
      <.js_component
        id="my-counter"
        component="Counter"
        props={%{counter: @counter}}
        callbacks={%{onIncrement: {"increment", "&1"}}}
      />
    """
  end

  def handle_event("increment", amount, socket) do
    IO.puts("Increment by #{amount}")
    {:noreply, socket}
  end

To do the above you need configure the hook in your app.js like so:

// ...
import { registerJsComponents } from "komodo";
+import componentFromReact from "komodo-react";
+import Counter from "path/to/react/counter/component";
// ...

let liveSocket = new LiveSocket("/live", Socket, {
  // ...
  hooks: {
    // ...
    komodo: registerJsComponents({
      // ...
+      Counter: componentFromReact(Counter)
    }),
  },
});
