YOUTUBE UPLOADS PLAYLIST BOOKMARKLET (UC → UU)
=============================================

OVERVIEW
--------
This bookmarklet extracts the YouTube Channel ID from the current channel page,
converts it from "UC..." to the Uploads playlist ID "UU...", and opens the
Uploads playlist in a new tab.

Works on YouTube channel pages, including "/@handle" URLs.


WHAT IT DOES
------------
1) Detects the YouTube Channel ID (starts with "UC")
2) Converts "UC" → "UU" (Uploads playlist)
3) Opens the uploads playlist in a new tab


SETUP (CHROME / EDGE / BRAVE)
-----------------------------
1) Show the bookmarks bar:
   - Windows/Linux: Ctrl + Shift + B
   - macOS: Cmd + Shift + B

2) Right-click the bookmarks bar → Add page… / Add bookmark…

3) Fill in:
   Name: YT – Play All Uploads
   URL:  (paste the BOOKMARKLET CODE below)

4) Save


SETUP (FIREFOX)
---------------
1) Enable Bookmarks Toolbar:
   View → Toolbars → Bookmarks Toolbar

2) Right-click the toolbar → Add Bookmark…

3) Fill in:
   Name: YT – Play All Uploads
   Location: (paste the BOOKMARKLET CODE below)

4) Save


HOW TO USE
----------
1) Open a YouTube CHANNEL page (not a video page)
   Example:
   https://www.youtube.com/@somechannel

2) Click the bookmarklet you saved

3) A new tab opens:
   https://www.youtube.com/playlist?list=UU...


BOOKMARKLET CODE (AUTO-OPEN UPLOADS PLAYLIST)
---------------------------------------------
IMPORTANT: Paste this as ONE SINGLE LINE in the bookmark URL field.

javascript:(()=>{const channelId=document.querySelector('meta[itemprop="channelId"]')?.content||window.ytInitialData?.metadata?.channelMetadataRenderer?.externalId;if(!channelId?.startsWith('UC')){alert('YouTube Channel ID not found');return}const playlistUrl=`https://www.youtube.com/playlist?list=${channelId.replace(/^UC/,'UU')}`;window.open(playlistUrl,'_blank')})()


OPTIONAL VARIATIONS
-------------------

A) Open uploads + live streams (UULT)
Paste as one line:

javascript:(()=>{const id=document.querySelector('meta[itemprop="channelId"]')?.content||window.ytInitialData?.metadata?.channelMetadataRenderer?.externalId;if(!id?.startsWith('UC')){alert('Channel ID not found');return}window.open(`https://www.youtube.com/playlist?list=${id.replace(/^UC/,'UULT')}`,'_blank')})()

B) Open full feed (uploads + shorts) (UULF)
Paste as one line:

javascript:(()=>{const id=document.querySelector('meta[itemprop="channelId"]')?.content||window.ytInitialData?.metadata?.channelMetadataRenderer?.externalId;if(!id?.startsWith('UC')){alert('Channel ID not found');return}window.open(`https://www.youtube.com/playlist?list=${id.replace(/^UC/,'UULF')}`,'_blank')})()


TROUBLESHOOTING
---------------
- A search page opens instead of running code:
  Make sure the URL starts with "javascript:" and is a single line.

- Alert says "Channel ID not found":
  Refresh the channel page and try again (YouTube loads dynamically).

- Doesn’t work on video pages:
  This is meant for CHANNEL pages only.


NOTES
-----
- "UC..." = Channel ID
- "UU..." = Auto-generated uploads playlist
- No YouTube Data API required
- No extensions needed
