# REXY

## Reverse Proxy in Elixir

Reverse proxy built on top of plug.

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `rexy` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [{:rexy, "~> 0.1.0"}]
end
```

## Fetaures

- Load Balancing(just use round robin for now)
- Domain based proxying(doesn't matter whether it's localhost or some other domain)
- Path based proxying(configuration in config.exs)
- SSL/TLS termination(just delete some headers)


## Configuration

All configuration is done throught `:upstreams`  
In config/config.exs list your server to point to your wanted hosts

Example:

```elixir
config :rexy,
       upstream: %{
         "load.com" => ["example.com", "google.bg"],
         "success.com" => {ReverseProxyTest.SuccessPlug, []},
         "api." => {ReverseProxyTest.SuccessPlug, []},
         "badgateway.com" => ["http://localhost:1"]
       }
```

We can route to a Plug, to a server, to a server built using Plug.
If we have an array of servers, it will use the load balancer and
rotate the servers every time we get a request.

If we want a domain proxy, then we just set the domain `api.`.

## You can embed it in other stuff

Just use `Plug.Router.forward/2` to pass a route to the reverse proxy.

```elixir
defmodule PlugReverseProxy.Router do
  use Plug.Router

  plug :match
  plug :dispatch

  forward "/users", to: ReverseProxy, upstream: ["dir.bg"]
```
