## Demonstration
2016-06-05 10:49:01 +02:00
Want to see in action?
2017-05-05 18:17:19 +02:00
* [Demo server](http://peertube.cpy.re)
* [Video](https://peertube.cpy.re/videos/watch/f78a97f8-a142-4ce1-a5bd-154bf9386504) to see how the "decentralization feature" looks like
* Experimental demo servers that share videos (they are in the same network): [peertube2](http://peertube2.cpy.re), [peertube3](http://peertube3.cpy.re). Since I do experiments with them, sometimes they might not work correctly.
## Why
2017-11-27 19:39:20 +01:00
We can't build a FOSS video streaming alternatives to YouTube, Dailymotion, Vimeo... with a centralized software. One organization alone cannot have enough money to pay bandwidth and video storage of its server.
So we need to have a decentralized network (as [Diaspora](https://github.com/diaspora/diaspora) for example).
2017-11-27 19:39:20 +01:00
But it's not enough because one video could become famous and overload the server.
It's the reason why we need to use a P2P protocol to limit the server load.
2016-04-30 13:13:07 +02:00
Thanks to [WebTorrent](https://github.com/feross/webtorrent), we can make P2P (thus bittorrent) inside the web browser right now.

2017-01-12 19:17:12 +01:00
$ git clone -b master https://github.com/Chocobozzz/PeerTube
$ cd PeerTube
2017-04-26 22:45:27 +02:00

2016-04-30 12:56:44 +02:00
## Usage
2016-05-20 15:27:16 +02:00
### Production
If you want to run PeerTube for production (bad idea for now :) ):
$ cp config/production.yaml.example config/production.yaml
Then edit the `config/production.yaml` file according to your webserver configuration. Keys set in this file will override those of `config/default.yml`.
2016-05-20 15:27:16 +02:00
Finally, run the server with the `production` `NODE_ENV` variable set.
$ NODE_ENV=production npm start
2017-01-27 11:18:53 +01:00
The administrator password is automatically generated and can be found in the logs. You can set another password with:
$ NODE_ENV=production npm run reset-password -- -u root
2017-04-09 12:13:51 +02:00
**Nginx template** (reverse proxy): https://github.com/Chocobozzz/PeerTube/tree/master/support/nginx <br />
**Systemd template**: https://github.com/Chocobozzz/PeerTube/tree/master/support/systemd
2016-10-21 12:16:07 +02:00
You can check the application (CORS headers, tracker websocket...) by running:
$ NODE_ENV=production npm run check
2016-10-21 14:52:21 +02:00
### Upgrade
The following commands will upgrade the source (according to your current branch), upgrade node modules and rebuild client application:
# systemctl stop peertube
$ npm run upgrade-peertube
2016-10-21 14:52:21 +02:00
# systemctl start peertube
2016-12-01 22:19:34 +01:00
### Development
2017-11-27 16:06:13 +01:00
In this mode, the server will run requests between instances more quickly, the video durations are limited to a few seconds.
2017-11-27 19:39:20 +01:00
To develop on the server-side (server files are automatically compiled when we modify them and the server restarts automatically too):
2017-06-11 11:29:03 +02:00
$ npm run dev:server
The server (with the client) will listen on `localhost:9000`.
2017-06-11 11:29:03 +02:00
To develop on the client side (client files are automatically compiled when we modify them):
$ npm run dev:client
2016-12-01 22:19:34 +01:00
The API will listen on `localhost:9000` and the frontend on `localhost:3000` (with hot module replacement, you don't need to refresh the web browser).
**Username**: *root* <br/>
**Password**: *test*
2017-01-27 11:18:53 +01:00
2016-12-01 22:19:34 +01:00
### Test with 3 fresh nodes
$ npm run clean:server:test
$ npm run play
2017-11-27 16:06:13 +01:00
Then you will get access to the three nodes at `http://localhost:900{1,2,3}` with the `root` as username and `test{1,2,3}` for the password.

### Backend
2016-07-21 10:37:29 +02:00
* The backend is a REST API
2017-11-27 16:06:13 +01:00
* Servers communicate with each others with [Activity Pub](https://www.w3.org/TR/activitypub/)
* Each server has its own users who query it (search videos, where the torrent URI of this specific video is...)
* If a user upload a video, the server seeds it and sends the video information (name, short description, torrent URI...) its followers
2015-06-09 17:41:40 +02:00
* A server is a tracker responsible for all the videos uploaded in it
2017-10-31 16:11:38 +01:00
* Even if nobody watches a video, it is seeded by the server (through [WebSeed protocol](http://www.bittorrent.org/beps/bep_0019.html)) where the video was uploaded
2015-06-09 17:41:40 +02:00
Here are some simple schemes:
