📦 Installation

Add to your Cargo.toml:

[dependencies]
bevy = "0.16"
bevy_cef = "0.1.0"

Platform Requirements

On macOS, using CEF typically requires creating an app bundle. For development, this library provides a debug feature flag. Once enabled, you can run the app without needing the bundle.

Note

Use this feature only during development; for releases, bundle the renderer process and the CEF framework inside the app.

Installation debug tools(macOS)

When using debug, you need to prepare a separate CEF framework and debug render process. Please follow the steps below to set it up.

> cargo install export-cef-dir
> export-cef-dir --force $HOME/.local/share/cef
> cargo install bevy_cef_debug_render_process 
> mv $HOME/.cargo/bin/bevy_cef_debug_render_process "$HOME/.local/share/cef/Chromium Embedded Framework.framework/Libraries/bevy_cef_debug_render_process"

Examples

See examples/.

On macOS, you need to enable debug feature enabled:

cargo run --example simple --features debug
