# Rack::SpyUp

Spying request and json response

[![wercker status](https://app.wercker.com/status/badde83f7252323fde185c68212600ba/m "wercker status")](https://app.wercker.com/project/bykey/badde83f7252323fde185c68212600ba)

* [Project page](http://udzura.jp/rack-spyup/)
* [Available as a RubyGem](http://rubygems.org/gems/rack-spyup).

## Installation

Add this line to your application's Gemfile:

gem 'rack-spyup'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-spyup

## Usage

```ruby
use Rack::SpyUp do |config|
  config.logger = Logger.new(STDOUT)
end
```

### `spyup` command

rack-spyup is shipped with `spyup` command.
You can use usual config.ru with request and response spyed:

```bash
$ spyup config.ru
```

`spyup` has the same options as `rackup` (except `--builder`),
because she uses `Rack::Server` internally.

### When you use rails

rack-spyup uses railtie system. In rails project, only you must do is just to set your Gemfile:

```ruby
gem 'rack-spyup'
```

BTW, if you want to use this middleware only via `spyup` command, just edit Gemfile:

```ruby
gem 'rack-spyup', require: false
```

Which does not enable middleware, and you may use the command `bundle exec spyup -p 3000` or like.

## Configurations

```ruby
Rack::SpyUp.config do |config|
  config.logger = Rails.logger # Set your custom logger
  config.enabled_environments = %w(development staging) # Set the rails envs you want to enable in
  # By default this is set to %w(development)
end
```
