Rekindle

Rekindle brings Cargo-based Rust UI builds into Elixir and Phoenix projects. Mix is the entry point for installation, development, Web packaging, and native release artifacts, while Cargo continues to manage Rust dependencies, compilation, target directories, and incremental caches.

GPUI, egui/eframe, and Slint are supported. Each integration can generate a browser target compiled to WebAssembly, a native desktop target, or both from a shared Rust UI crate.

Requirements

• Elixir 1.17 or later
• Rust and Cargo
• A Phoenix project generator
• Linux with procfs mounted at /proc
• setsid, pkill, and kill
• The Rust targets and native system libraries required by the selected UI integration

Create a project

Install the Igniter and Phoenix project generators:

mix archive.install hex igniter_new
mix archive.install hex phx_new

Create a Phoenix application with a GPUI client for Web and desktop:

mix igniter.new my_app \
  --with phx.new \
  --install rekindle \
  --integration gpui \
  --targets web,desktop

Then prepare the required tools and start development:

cd my_app
mix rekindle.setup
mix rekindle.dev

See the Getting Started guide for existing Phoenix applications and the remaining setup options. Complete guides and API documentation are published on HexDocs.
