WorkerGlobalScope.importScripts

The importScripts() method of the WorkerGlobalScope interface synchronously imports one or more scripts into the worker's scope.

Syntax

self.importScripts('foo.js');
self.importScripts('foo.js', 'bar.js', ...);

Parameters

A comma-separated list of DOMString objects representing the scripts to be imported.

Return value

None.

Exceptions

  • NetworkError is raised if the MIME type of one of the script is text/csv, image/*, video/*, or audio/*. It should always be text/javascript.

Example

If you had some functionality written in a separate script called foo.js that you wanted to use inside worker.js, you could import it using the following line:

importScripts('foo.js');

importScripts() and self.importScripts() are effectively equivalent — both represent importScripts() being called from inside the worker's inner scope.
