pine

vine clone over IPFS

How to run

Requires nodejs version 9.0.0 or higher and yarn

• Clone the repository
• Run yarn to install the dependencies (or npm install if you use npm)
• Run the dev command to serve frontend via either yarn or npm
  • yarn dev OR npm run dev
• Run the caching server via either yarn or npm
  • yarn start OR npm start

Now you should be able to see the application on localhost:8080

Navigating to the website, you should see the start page, showing a "Record new Pine" in the bottom, and a permission dialog asking for permission to access your camera. Accept that. Also, open up the browser's javascript console, so you can see any potential errors ( currently doesn't handle errors very good)

Then click on "Record new Pine" to go to the recording screen.

Once on the recording screen, click and hold down on the camera output to begin recording. You should see a progress-bar in the bottom. Make sure to release the mouse before it fills up, as each recording can only be ~6 seconds long.

Once you let go, press the "Publish" button and you should be able to see a preview of your recording. If you're happy with it, click "Publish" in the top-right, and your recording will be published on IPFS. You can see the link being printed in your browser's console.

list of videos

---

Upon opening, a peer should send GET_VIDEOS_HEAD message on PINE topic via pubsub. Online peers will respond with SEND_VIDEOS_HEAD which is a hash of the latest version that peer have seen of the list of videos. The peer who requested the list will take the first seen message and fetch the list from that.

A list of videos looks like this:

[{
  title: 'Look, a funny cat!',
  video: '/ipfs/Qkamlfknawleknfal',
  created_at: '2017-10-08T16:05:42.023Z'
}]

It will also be possible to run Hoster nodes to listen and respond to queries in case no other peers are online.
