 1 | # Bittorrent example
 2 | 
 3 | A simple example of file transfer using Bittorrent protocol.
 4 | 
 5 | It uses [bittorrent-tracker](https://github.com/feross/bittorrent-tracker) and [webtorrent](https://github.com/feross/webtorrent) under the hood.
 6 | 
 7 | ## Steps
 8 | 
 9 | 1. Install dependencies: `npm install`
10 | 2. Start a Bittorrent tracker server on port 8000: `bittorrent-tracker`
11 | 3. Open another terminal and start seeding *hello world* with: `node seeder.js`
12 | 4. Run this in another terminal: `node leecher.js`
13 | 
14 | ## FAQ
15 | 
16 | #### How did you generate the magnet hash?
17 | 
18 | Use `create-torrent` and `magnet-link`.
19 | 
20 | ```
21 | npm install -g create-torrent magnet-link
22 | ```
23 | 
24 | Magnet hash is generated with the following command
25 | 
26 | ```
27 | create-torrent message | magnet-link
28 | ```
29 | 
30 | and then appending the other params like download name and tracker to it. So the above command gives us `magnet:?xt=urn:btih:b8e8adbee320fc312e5fd71479329c3d53c40aea` and we append more params to it so it uses our tracker on port 8000: 
31 | ```
32 | magnet:?xt=urn:btih:b8e8adbee320fc312e5fd71479329c3d53c40aea&dn=message&tr=http%3A%2F%2Flocalhost%3A8000%2Fannounce
33 | ```
34 | 
35 | You also get the same magnet link printed to the console if you run the seeder first with `node seeder.js`.
