## Description

ronin-web-browser is a Ruby library for automating the Chrome web browser.
ronin-web-browser builds on the [ferrum] gem, and adds additional API methods
that are useful to security researchers.

## Features

* Automates the Chrome web browser.
* Supports running in visible or headless mode.
* Supports using a HTTP proxy.
* Supports event hooks for requests and responses.
* Supports parsing, setting, loading, and saving cookies.
* Supports saving screenshots into a directory or git repository.
* Small memory footprint (~50Kb Ruby + ~600Kb headless Chrome).
* Has 81% documentation coverage.
* Has 82% test coverage.

## Examples

Initialize a headless browser:

```ruby
browser = Ronin::Web::Browser.new
# ...
browser.quit
```

Initialize a visible browser:

```ruby
browser = Ronin::Web::Browser.new(visible: true)
# ...
browser.quit
```

Opening a temporary browser and automatically quitting:

```ruby
Ronin::Web::Browser.open do |browser|
  # ...
end
```

Initializing the browser with a proxy:

```ruby
browser = Ronin::Web::Browser.new(proxy: "http://proxy.example.com:8080")
# ...
```

Go to and screenshot a webpage:

```ruby
Ronin::Web::Browser.open do |browser|
  browser.go_to("https://google.com")
  browser.screenshot(path: "google.png")
end
```

Intercept all requests:

```ruby
browser = Ronin::Web::Browser.new
browser.every_request do |request|
  puts "> #{request.method} #{request.url}"
end

browser.go_to("https://twitter.com/login")
```

Intercept all responses for all requests:

```ruby
browser = Ronin::Web::Browser.new
browser.every_response do |response,request|
  puts "> #{request.method} #{request.url}"

  puts "< HTTP #{response.status}"

  response.headers.each do |name,value|
    puts "< #{name}: #{value}"
  end

  puts response.body
end

browser.go_to("https://twitter.com/login")
```

Evaluate JavaScript within the current page:

```ruby
browser = Ronin::Web::Browser.new
browser.goto('https://github.com')
browser.eval_js('document.cookie')
# => "..."
```

Load a JavaScript file into the current page as a `<script>` tag:

```ruby
browser.load_js(url: 'https://.../file.js')
```

Load JavaScript code into the current page as a `<script>` tag:

```ruby
browser.load_js(content: '...')
```

Inject JavaScript code into *every* page:

```ruby
browser.inject_js('...')
```

See [ferrum] for additional documentation.
