.call(js_req, js_env, js_ctx, body_text = '') ⇒ Object

Entry point invoked from the Module Worker (src/worker.mjs) for every fetch event. ‘js_req` is a Cloudflare Workers Request, `js_env` is the bindings object (D1, KV, R2, secrets…), `js_ctx` is the ExecutionContext, `body_text` is the pre-resolved request body (the worker.mjs front awaits req.text() before handing control to Ruby because Opal runs synchronously).
