Installation

Add Popcorn to your dependencies

Add the following to your mix.exs file:
mix.exs
```
{:popcorn, github: "software-mansion/popcorn"}
```
Configure Popcorn

Create or update your config.exs file:
config.exs
```
config :popcorn,
  start_module: HelloPopcorn,
  out_dir: "static/wasm"
```
Currently Popcorn only supports having output files in wasm/ directory.
Create your entrypoint module

Define a module that will serve as your application’s entry point:
hello_popcorn.ex
```
defmodule HelloPopcorn do
  def start() do
    Popcorn.Wasm.register("main")

    :ok
  end
end
```
In the future Popcorn will support OTP applications and there will be no need for additional entrypoint module.

Initialize Popcorn in your HTML

Add the following script to your HTML file:

<script type="module">
  import { Popcorn } from "./wasm/popcorn.js";

  await Popcorn.init({ onStdout: console.log });
</script>
