Inter-process communication

PyTauri implements an IPC API similar to that of Tauri. For more information on the different IPC mechanics, you can read the Tauri documentation on calling Rust from the Frontend

There are three ways of communicating between the frontend and backend:

1. Commands: One-way communication (frontend to backend) with type safety.
2. Channels: Two-way communication designed for fast and delivering ordered data.
3. Events: Simple communication system that only supports JSON payloads. Works bidirectionally.

Additionally, there is WebviewWindow.eval which can be used to directly execute JavaScript from Python. This, however, is unrecommended as it has no security and generally has no use case above the prior mentioned systems.

Commands

Commands can be compared to the fetch API of browsers. The primary API, pyInvoke is used similarly to Tauri's native invoke API.

Channels

Channels work similarly to websockets. They must be initialized first through a command but afterward can send data at high speeds.

Events

The event system uses Emitters and Listeners which are available in both the front- and backend to pass data between the two.
