SponsorBlock is an open-source crowdsourced browser extension to skip sponsor segments in YouTube videos. Users submit when a sponsor happens from the extension, and the extension automatically skips sponsors it knows about. It also supports skipping other categories, such as intros, outros and reminders to subscribe. It also supports Invidio.us. **Translate:** [![Crowdin](https://badges.crowdin.net/sponsorblock/localized.svg)](https://crowdin.com/project/sponsorblock) # Important Links See the [Wiki](https://github.com/ajayyy/SponsorBlock/wiki) for important links. # Server The backend server code is available here: https://github.com/ajayyy/SponsorBlockServer To make sure that this project doesn't die, I have made the database publicly downloadable at https://sponsor.ajay.app/database ([License](https://github.com/ajayyy/SponsorBlock/wiki/Database-and-API-License)). If you are planning on using the database in another project, please read the [API Docs](https://wiki.sponsor.ajay.app/index.php/API_Docs) page for more information. The dataset and API are now being used in some [ports](https://github.com/ajayyy/SponsorBlock/wiki/3rd-Party-Ports) as well as a [neural network](https://github.com/andrewzlee/NeuralBlock). # API You can read the API docs [here](https://wiki.sponsor.ajay.app/index.php/API_Docs). # Building You must have [Node.js 16](https://nodejs.org/) and npm installed. 1. Copy the file `config.json.example` to `config.json` and adjust configuration as desired. - You will need to repeat this step in the future if you get build errors related to `CompileConfig`. This can happen for example when a new category is added. 2. Run `npm install` in the repository to install dependencies. 3. Run `npm run build:dev` (for Chrome) or `npm run build:dev:firefox` (for Firefox) to generate a development version of the extension with source maps. - You can also run `npm run build` (for Chrome) or `npm run build:firefox` (for Firefox) to generate a production build. 4. The built extension is now in `dist/`. You can load this folder directly in Chrome as an [unpacked extension](https://developer.chrome.com/docs/extensions/mv3/getstarted/#manifest), or convert it to a zip file to load it as a [temporary extension](https://developer.mozilla.org/en-US/docs/Tools/about:debugging#loading_a_temporary_extension) in Firefox. ### Developing with a clean profile and hot reloading Run `npm run dev` (for Chrome) or `npm run dev:firefox` (for Firefox) to run the extension using a clean browser profile with hot reloading. This uses [`web-ext run`](https://extensionworkshop.com/documentation/develop/web-ext-command-reference/#commands). Known chromium bug: Extension is not loaded properly on first start. Visit `chrome://extensions/` and reload the extension. For Firefox for Android, use `npm run dev:firefox-android -- --adb-device
