8 | Intro
9 | -----
10 |
11 | SAMPLE application consist of two page modules `login` and `index`.
12 | It creates WebSocket connection to `n2o` server.
13 | The permanent example is accesible at https://sample.n2o.dev/index.htm.
14 |
15 | Index
16 | -----
17 |
18 | Init event.
19 | Chat event.
20 | Client event.
21 | File Transfer event.
22 |
23 | Login
24 | -----
25 |
26 | Channel init.
27 | Login event.
28 |
29 | Setup
30 | -----
31 |
32 | To run review application just clone, build and run:
33 |
34 | ```
35 | $ rebar3 get-deps
36 | $ rebar3 shell
37 | ```
38 |
39 | Then open it in browser:
40 |
41 | ```
42 | $ open http://localhost:8001/app/login.htm
