WorkerGlobalScope: importScripts() method

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

Syntax

js

importScripts(path0)
importScripts(path0, path1)
importScripts(path0, path1, /* … ,*/ pathN)

Parameters

pathN

A string value representing the URL of the script to be imported. The URL may be absolute or relative. If the URL is relative, it is relative to the HTML document's base URL.

Return value

None (undefined).

Exceptions

NetworkError

Imported scripts were served without a text/javascript MIME type or without one of the permitted legacy JavaScript MIME types.

Examples

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:

js

importScripts("foo.js");

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