SharedWorker: port property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The port property of the SharedWorker interface returns a MessagePort object used to communicate and control the shared worker.
Value
A MessagePort object.
Examples
The following code snippet shows creation of a SharedWorker object using the SharedWorker() constructor. Multiple scripts can then access the worker through a MessagePort object accessed using the SharedWorker.port property — the port is started using its start() method:
js
const myWorker = new SharedWorker("worker.js"); myWorker.port.start(); For a full example, see our Basic shared worker example (run shared worker.)
