Is there a way to download the requested files by the browser locally?

I do not know where it is more correct to ask this question.

I am developing a website. Configured automatic sending of files to the server. Building js files takes time. Download from server too.

But I can build js files locally.

Is there a way to make js files loaded bypassing the server?

For example, when the browser makes a request https://my-site.com/js/app.js, make it load the file not from the site, but from the local folder: c:\projcets\my-site\public\js\app.js
