You need to configure your watcher how often do you want to run it. Supported alerting channels are email and slack.

You can customize queries and filters so as intervals between fetching each page, because you don't want to send too many requests and act as an idiot.

Configuration

Configuration file looks like this:

{
	"runIntervalMinutes": 1,
	"sleepIntervalSeconds": 2,
	"queries": [{
		"baseQueryPath": "iznajmljivanje-stanova/zagreb",
		"filters": {
			"locationId": "2619",
			"price[max]": "260",
			"mainArea[max]": "50"
		}
	}],
	"slack" : true,
	"slackToken": "",
	"slackChannelId" : "",
	"slackNotificationColor": "#fdcd00",
	"mail": true,
	"to": "myemail@gmail.com",
	"mailgunDomain":"",
	"mailgunAPIKey":"",
	"mailgunPublicKey":""
}

It can be found in: {$HOME}/.njuhalo

If there is no such file you can create it manually or just run: /.njuhalo i

Adding queries

Adding queries can be pain in the ass so you can simply paste it like this

/.njuhalo a http://www.njuskalo.hr/path?query=1&query=2

That will parse query and save it to the default config file.

Number of queries is not limited and you can add as much as you want.

Development

Location of all njuhalo config and db is in your home folder

{$HOME}/.njuhalo

To build binary from scratch:

go build
