# OwlCrawler

It's a distributed web crawler that uses [nats.io](http://nats.io) to coordinate work, written in Go.

## Dependencies

* CouchDB 1.x (tested on 1.6.1)

* gnatsd

## Building.

Build the two workers

```

go build  -tags=fetcherExec -o fetcher fetcher.go && \

go build  -tags=extractorExec -o extractor extractor.go

```

### Setup

1. Setup couchdb with at least one admin user, you can follow the instructions [here](http://stackoverflow.com/a/6418670/309896)

2. create a file `.couchdb.json` and place it in your `$HOME` directory

 Sample `.couchdb.json`

    ```

  {

    "user": "user-here",

    "password": "super-secret-password",

    "url": "http://localhost:5984/owl-crawler"

  }

    ```

3. create a file `.gnatsd.json` and place it in your `$HOME` directory

 Sample `.gnatsd.json`

    ```

    {

      "URL": "nats://owlcrawler:[email protected]:4222"

    }

    ```

4. Start gnatsd with a user and password (use a config file, but for a quick test

	you can pass parameters):

```

~/gnatsd --user owlcrawler --pass natsd_password

```

#### On terminal 1 run:

```

./extractor -logtostderr=true -v=3

```

#### On terminal 2 run:

```

./fetcher -logtostderr=true -v=3

```

#### On terminal 3 run:
