# Funkspector

[![Deps Status](https://beta.hexfaktor.org/badge/all/github/jaimeiniesta/funkspector.svg)](https://beta.hexfaktor.org/github/jaimeiniesta/funkspector)

Web page inspector for Elixir.

Funkspector is a web scraper that lets you extract data from web pages.

## Usage

Simply pass Funkspector the URL to inspect and it will return its scraped data:

```elixir
iex> { :ok, data } = Funkspector.scrape("http://github.com")
```

## Scraped data

Currently Funkspector returns this scraped data from the given URL:

* `body`. Raw body.
* `original_url` and `final_url`. Funkspector follows redirections, here are the original URL given and the final one after following the redirections.
* `scheme`. Like, "http" or "https".
* `host`. Like, "github.com".
* `links`. Organized in `raw`, `http.internal`, `http.external` and `non_http`.
* `root_url`. Root url for the given URL. For `http://example.com/about` it will be `http://example.com`.

## Error response

In case of error, Funkspector will return the `original_url` and the response from the server:

```elixir
case Funkspector.scrape("http://example.com") do
  { :ok, data } ->
    IO.inspect(data)
  { :error, url, response } ->
    IO.puts "Could not scrape #{url} because of #{reason}"
end
```
