Tauri Runtime Authority
The runtime authority is a core Tauri component that enforces security policies during application execution. It validates permissions, resolves capabilities, and injects scopes before commands execute.
What Is Runtime Authority?
Runtime authority is the enforcement layer that sits between the WebView frontend and Tauri commands. It acts as a gatekeeper for all IPC (Inter-Process Communication) requests.
Core Function
When a webview invokes a Tauri command, the runtime authority:
- Receives the invoke request from the webview
- Validates the origin is permitted to call the requested command
- Confirms the origin belongs to applicable capabilities
- Injects defined scopes into the request
- Passes the validated request to the Tauri command
If the origin is not allowed, the request is denied and the command never executes.
