Popcorn: Run Elixir in WASM

a year ago

Popcorn is a library that enables execution of Elixir code within web browsers using WASM.
Compiled Elixir code runs in the client-side AtomVM runtime, with APIs for JS-Elixir interaction.
Popcorn provides serialization, communication handling, and ensures browser responsiveness.
Setup involves adding Popcorn as a dependency, configuring JS and Elixir WASM entrypoints.
JS setup includes generating directories for WASM and including scripts in HTML.
Elixir requires a WASM entrypoint module with a `start/0` function and configuration.
Communication between JS and Elixir is managed via messages and direct JS execution from Elixir.
Popcorn's API includes methods for sending messages, executing JS, and handling events.
Limitations include missing NIFs from OTP, no support for big integers, and unstable API.
Under the hood, Popcorn uses AtomVM runtime compiled via Emscripten, loaded in an iframe.
Popcorn is created by Software Mansion, experts in web, mobile, and multimedia solutions.
