Bevy Remote Protocol (BRP)

The Bevy Remote Protocol (BRP) is a transport-agnostic and serialization-agnostic protocol for communication between a Bevy application (acting as a server) and a remote (or local) client. It's a request/response-style protocol (similar to HTTP), meaning that every communication is always initiated by the client, and the server only responds to the client's requests.

Example Uses

• A editor/inspector, allowing the user to inspect and modify the Bevy application's state in real time, both locally and remotely;
• “Gameshark“-style cheats, allowing the user to modify a game's state in real time;
• JS/HTML-based UI interacting with an embedded Bevy application running in a browser;
• Non-Bevy/Rust applications (e.g. a C++/Python/Java application) interacting with embedded Bevy modules;

What this is?

This is a simple experiment to verify if browsers will block/hang execution in a page when a child iframe (of a different origin) has a running script blocked in an infinite loop.

As of Nov 4, 2021, Chrome/Edge won't block the parent page, but Firefox and Safari will.

Instructions

You'll need Node and NPM for this.
