Simplify & add to docs to communicate to the "external" site

[kostafey]

For example, there is an application running on localhost:8080.

The steps to communicate to this "external" site.

1. (setq httpd-port 8081) in .emacs
2. Install greasemonkey for Firefox or tampermonkey for Chrome.
3. Add skewer-everything.user.js script.
4. Modify this script:

var host = 'http://localhost:8081';

5. M-x run-skewer (get new tab for localhost:8081)
6. M-x skewer-repl
7. Reload target "external" localhost:8080 tab in browser
8. At this point, you'll get 2 clients in skewer-repl. So you have to close localhost:8081 tab.

Is there are any simpler way?

Greasemonkey/Tampermonkey is only necessary for the userscript, which itself isn't necessary just to use Skewer. The run-skewer command already injects Skewer into the page, and you can include the script in any pages you control. The only steps you care about in this case are in the README under "Manual version."

Oh, really. Thank you. But if you need to reload original localhost:8080, you will get 2 results any time you run js code (one from original "remote" localhost:8080, other from plain js process) until you close skewer localhost:8081 tab.
