Methods

createSession()

createSession(globals?: Record<string, unknown>): AxCodeSession;

Defined in: https://github.com/ax-llm/ax/blob/71ea5064d766efdc031d375243a8e525911833e7/src/ax/funcs/jsRuntime.ts#L684

Creates a persistent execution session.

Message flow:

1. Main thread sends init with globals, function proxies, permissions.
2. Main thread sends execute with correlation ID and code.
3. Worker returns result or requests host callbacks via fn-call.
4. Host responds to callback requests with fn-result.

Session closes on:

• explicit close(),
• timeout,
• abort signal,
• worker error.

Parameters

Returns

AxCodeSession
