# GenAmqp
GenAMQP is a set of utilities to make microservices using the worker pattern, where you can have many workers listening on a queue and they can execute this in a synchronous or asynchronous.
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:
1. Add `gen_amqp` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:gen_amqp, "~> 0.6.0"}]
end
def application do
[applications: [:gen_amqp]]
end
```
2. Add the connection url to the config.exs
```elixir
config :gen_amqp, GenAMQP.Conn,
amqp_url: System.get_env("RABBITCONN") || "amqp://@localhost"
```
3. Create a module and configure it:
```elixir
defmodule ServerDemo do
@moduledoc false
use GenAMQP.Server, event: "demo", size: 5 # amount of instances
def execute(_) do
{:reply, "ok"}
end
end
```
4. Add it to the app:
```elixir
defmodule DemoApp do
@moduledoc false
use Application
def start(_type, _args) do
import Supervisor.Spec, warn: false
# Define supervisors and child supervisors to be supervised
children = [
supervisor(ServerDemo, []),
]
opts = [strategy: :one_for_one, name: Core.Supervisor]
Supervisor.start_link(children, opts)
end
end
```
