ExGrok

Low dependencies ngrok wrapper.

Tiny wrapper that will take care about ngrok connection for your Phoenix web applications you're working on and want to share with broader audience without need of deploying it.

Installation

The package can be installed as:

1. Add ex_grok to your list of dependencies in mix.exs:

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

1. Ensure ex_grok is started before your application:

```elixir
def application do
  [applications: [:ex_grok]]
end
```

Configuration

By default ex_grok will try to establish connection only in dev environment. It is easy to change this behaviour by enabling it in config/config.exs file:

config :ex_grok, enabled: true

ngrok provides couple possible connection options, ex_grok however, makes use of http only at the moment.

It will try to use global ngrok command exposing port 4000 (default port that Phoenix uses in development), but it can be changed in config/config.exs:

config :ex_grok, :command,
  executable: "path/to/ngrok",
  port: "3040"

Usage

Once your application is up and running, and ngrok connection has been established successfully, the available urls will be reported in logs:

20:48:28.447 [info]  ngrok connection established - http://12345678.ngrok.io, https://12345678.ngrok.io

The same information can be obtained with ExGrok.connection/1:

iex> ExGrok.connection()
%ExGrok.Connection{http: "http://12345678.ngrok.io",
                   https: "https://12345678.ngrok.io"}
