# p2p chat app with libp2p
|
||
|
|
|
||
|
|
This program demonstrates a simple p2p chat application. It can work between two peers if
|
||
|
|
1. Both have a private IP address (same network).
|
||
|
|
2. At least one of them has a public IP address.
|
||
|
|
|
||
|
|
Assume if 'A' and 'B' are on different networks host 'A' may or may not have a public IP address but host 'B' has one.
|
||
|
|
|
||
|
|
Usage: Run `./chat -sp <SOURCE_PORT>` on host 'B' where <SOURCE_PORT> can be any port number. Now run `./chat -d <MULTIADDR_B>` on node 'A' [`<MULTIADDR_B>` is multiaddress of host 'B' which can be obtained from host 'B' console].
|
||
|
|
|
||
|
|
## Build
|
||
|
|
|
||
|
|
From the `go-libp2p/examples` directory run the following:
|
||
|
|
|
||
|
|
```
|
||
|
|
> cd chat/
|
||
|
|
> go build
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
On node 'B'
|
||
|
|
|
||
|
|
```
|
||
|
|
> ./chat -sp 3001
|
||
|
|
Run ./chat -d /ip4/127.0.0.1/tcp/3001/p2p/QmdXGaeGiVA745XorV1jr11RHxB9z4fqykm6xCUPX1aTJo

2018/02/27 01:21:32 Got a new stream!
|
||
|
|
> hi (received messages in green colour)
|
||
|
|
> hello (sent messages in white colour)
|
||
|
|
> no
|
||
|
|
```
|
||
|
|
|
||
|
|
On node 'A'. Replace 127.0.0.1 with <PUBLIC_IP> if node 'B' has one.
|
||
|
|
|
||
|
|
```
|
||
|
|
> ./chat -d /ip4/127.0.0.1/tcp/3001/p2p/QmdXGaeGiVA745XorV1jr11RHxB9z4fqykm6xCUPX1aTJo
|
||
|
|
Run ./chat -d /ip4/127.0.0.1/tcp/3001/p2p/QmdXGaeGiVA745XorV1jr11RHxB9z4fqykm6xCUPX1aTJo
|
||
|
|
|
||
|
|
This node's multiaddress:
|
||
|
|
/ip4/0.0.0.0/tcp/0/p2p/QmWVx9NwsgaVWMRHNCpesq1WQAw2T3JurjGDNeVNWifPS7
|
||
|
|
> hi
|
||
|
|
> hello
|
||
|
|
```
|
||
|
|
|
||
|
|
**NOTE: debug mode is enabled by default, debug mode will always generate the same node id (on each node) on every execution. Disable debug using `--debug false` flag while running your executable.**
|
||
|
|
|
||
|
|
**Note:** If you are looking for an implementation with peer discovery, [chat-with-rendezvous](../chat-with-rendezvous), supports peer discovery using a rendezvous point.
