WorkerGlobalScope: navigator property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.

We’d love to hear your thoughts on the next set of proposals for the JavaScript language. You can find a description of the proposals here.
Please take two minutes to fill out our short survey.

Note: This feature is only available in Web Workers.

The navigator read-only property of the WorkerGlobalScope interface returns the WorkerNavigator associated with the worker. It is a specific navigator object, mostly a subset of the Navigator for browsing scopes, but adapted to workers.

Value

A WorkerNavigator object.

Examples

If you call the following:

js
console.log(navigator);

inside a worker (which would basically be the equivalent of self.console.log(self.navigator);, as these are being called on the worker scope, which can be referenced with WorkerGlobalScope.self), you will get a WorkerNavigator object written to the console — something like the following:

Object {onLine: true, userAgent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) Ap…ML, like Gecko) Chrome/40.0.2214.93 Safari/537.36", product: "Gecko", platform: "MacIntel", appVersion: "5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKi…ML, like Gecko) Chrome/40.0.2214.93 Safari/537.36"…}
    appCodeName: "Mozilla"
    appName: "Netscape"

    __proto__: Object

You could use this navigator object to return more information about the runtime environment, as you might do with a normal Navigator object.
