Introduction
============

ngx-stomp is a nginx 3rd party module which allow to send http request and proxy to stomp amqp protocol server with given pre-defined/dynamic frame.

Usage
=======
### 0. Setup your stomp upstream and subscribed queue
```nginx
# nginx.conf
upstream stomp {
stomp_subscribes /amq/queue/stompqueue;
stomp_endpoint 127.0.0.1:61618 login=guest passcode=guest max_send_sess=3 max_recv_sess=3;
}
```

### 1. Simple create stomp frame command,
```nginx
# nginx.conf

server {
....
location /sendqueue {
stomp_pass stomp;
stomp_command SEND;
stomp_headers "destination:/amq/queue/stompqueue
persistent:false
content-type:text/plain
content-length:38";
stomp_body "This is new message sending from stomp";
}
}
```

### 2. Simple consuming the queue destination which pre-defined from upstream
```nginx
# nginx.conf

server {
....

location /consume {
stomp_pass stomp;
stomp_command CONSUME;
}
}
```

Directive
=========

| Key | Description |
| ------------- |:-------------: |
| stomp_subscribes | which need to defined in upstream block, to tell that which destination queue going to subscribe |
| stomp_endpoint | the AMQ server which has stomp protocol feature. |
| max_send_sess | the maximum connection which allow to use for sending message to amq server, default is 10 |
| max_recv_sess | the maximum connection which allow to use for consuming message from amq server, default is 5 |
| stomp_pass | upstream to stomp. |
| stomp_command | frame command ( Please note that 'CONSUME' command is the extra command which allow you to consume the message via HTTP request ) |

Test
=====

It depends on nginx test suite libs, please refer [test-nginx](https://github.com/openresty/test-nginx) for installation.

export PATH=/path/to/nginx-dirname:$PATH
sudo prove t
```

Tips
=====

The more subscribe session you set, the more consumer will listen to the subscribed queue, suggested to set a fixed consumer session that are constantly consuming the queue, else the broker might send to some consumer which is not actively call for consuming

For example, if you set `max_recv_sess=5`, it will subscribe 5 listener later, you should have 5 connection to do constantly polling. If you just need one polling please set to `max_recv_sess=1`, then you connection polling should not be more than 1.

Example of 1 receving session and 3 sending session.

Example of 5 receving session and 10 sending session.
