Invidious Extension

A Userscript with Backend to extend the functionality of Piped & Invidious and enable syncing between instances.
(Support for Invidious is discontinued.)

Please note that this application is (and most certainly will ever be) in an experimental stage.

Features

• Stacks: save the currently playing video with timestamp (+ last played videos) to reopen it later
• group playlists in the playlist-overview
• download as video or mp3 (with simple ID3-tagger)
• sync playlists between instances
• show exact upload-dates of videos in playlist-detail and recommended-videos
• play a playlist backwards
• sync extension-specific data between browsers (e2e encrypted)
• sync Invidious / Piped settings between instances
• sync Piped subscriptions and subscription-groups between instances

Installation and Usage

1. install the UserScript Plugin Violentmonkey
2. open https://chocolatecakecodes.goip.de/InvidiousExt/invidious-extension.user.js (the Plugin should open the installation-dialog)

You should now see a blue icon in the top-bar of supported Piped and Invidious instances. (If not, try reloading the page.)
This is the menu with all the functionality (some entries are page-dependent or appear after the player fully loaded).

Almost all features are available without an account.
Only for cross-browser sync and download you need one.

Deploy

If you want to deploy your own instance, follow these steps:

1. clone the Repo
2. update UserScripts/vite.config.ts and set the download URL and connect array accordingly
3. update UserScripts/src/util/constants.ts and set SERVER_BASE_URL accordingly
4. run the Gradle task :Server:assemble of module Invidious_Extension:Server (with env vars MICRONAUT_ENVIRONMENTS=prod)
5. run the Gradle task build of module Invidious_Extension:UserScripts
6. make sure a PostgreSQL server is available for the Backend
7. make sure yt-dlp is available in the PATH for the Backend
8. run the Backend (Server/build/libs/Server-<ver>-all-optimized.jar) on your server with the fitting Env-Vars
9. copy UserScripts/dist/invidious-extension.user.js onto your server (under the subpath you used in vite.config.js)

Env-Vars:

Var	Description
INVIDIOUS_EXT_DB_HOST	hostname of database
INVIDIOUS_EXT_DB_NAME	name of database
INVIDIOUS_EXT_DB_USER	user for database
INVIDIOUS_EXT_DB_PASSWORD	password for database-user
INVIDIOUS_EXT_SUBPATH	subpath the Backend is reachable from (must be at least /)
