Need help with a userscript

[specter78]

// ==UserScript==
// @name       Redirect
// @match      *://www.reddit.com/*
// @run-at     document-start
// @noframes
// ==/UserScript==

query = window.location.href.split("www.reddit.com")[1];
window.location.href = "https://libredd.it" + query;

I want the redirect to happen before page load. However, in reality, redirect happens after the page is loaded.

System Information:

macOS version: 12.0.1
Userscripts version: 3.3.1
Safari version: 15.1
Is this issue related to script injection? Yes
Did the test script (pasted above) successfully run on your machine? Yes and No

That's not possible. Injection happens after the page has already begun to load and the soonest you can initiate the redirect is document-start as you are already doing. However with some website, like Reddit, you're competing with all the other junk it loads and it doesn't happen as instantaneous as I (and probably you) would like.

The available options are:

• @run-at
  • allows the user to choose the injection timing
  • document-start, document-end (default), document-idle
  • works like violentmonkey

Can you elaborate on what did not work with the test script?

It is working, but not how I want it to (which you’ve already explained).

Currently userscripts execute as soon as possible with document-start. I spent a lot of time trying to get them to execute quicker but it wasn't seemingly possible due to the way webNavigation was handled by Safari web extensions.

I was hoping to execute the moment a user commits a navigation and inject the user scripts outside of the content script, but alas that was not feasible.

I'm sorry script execution doesn't match your expectations. In some time I will do some more testing to see if anything changed but for now there's no way around it.

I wish I could have been of more help.

@specter78 I am closing this issue

If you care to track progress, if any, on injection time speed you can do so in this issue #184
