Miso.Runtime.Internal

Description

Overview

Miso.Runtime.Internal is a testing-only facade that re-exports the miso runtime's global mutable state from Miso.Runtime.

Do not import this module in application code. Mutating any of the exported IORef values will corrupt the component lifecycle and produce undefined behaviour. The module exists solely to give the miso-tests integration-test package direct access to component state for assertions.

Exported names

components — global IORef mapping ComponentId to ComponentState for every mounted component.
componentIds — monotonically increasing IORef used to assign fresh component identifiers.
rootComponentId — the well-known identifier of the top-level app component.
ComponentState — record holding the live model, scheduler mailbox, and other per-component runtime fields.
schedulerThread — IORef holding the ThreadId of the event-loop scheduler thread.
