Appfail JavaScript Reporting Module

Development note: appfail-reporting.js must pass JSHint Linting in order for it to be valid.

Installation

To begin reporting Javascript failures to appfail, add the following script tag into your page:

<script type="text/javascript" src="https://s3.amazonaws.com/appfail-us/appfail.reporting.min.js?slug=abc123"></script>

Testing

OK, so you've plugged in the reporting script, but your not seeing any failures in Appfail. Have you written perfect Javascript code, or is something going wrong!?

You can fire a 'test' exception at appfail from your page, by adding the following value to your page's query string: http://myurl.com/somepage?appfail-report-test-exception=1

Configuration

Appfail's reporting module can be configured by modifying the query string of the URL in the <script /> tag, or by calling a javascript function.

Settings that can be configured, and their defaults:

appfail.configure({
	slug: 'abc123', 			// your app slug
	processInterval: 10, 	// how often the errors should be sent to the server (try not to DDoS it!)
	daysToStore: 7,			// number of days before stored errors are invalidated
	onBeforeStore: null		// function to parse the report values before it's stored or sent to the server
});

Query string Each of these settings can be configured via the query string of the URL in the <script /> include.

<script type="text/javascript" src="https://s3.amazonaws.com/appfail-us/appfail.reporting.min.js?slug=abc123"></script>

The following functions are exposed

• appfail.reporting.catchManual(e) use with a try {} catch(e) {}
• appfail.reporting.processQueue() for manually sending the queue of errors
• appfail.reporting.storeQueue() push the current messageQueue to localStorage
• appfail.reporting.loadStoredErrors() restore the saved errors from localStorage to the internal messageQueue. Note: This does not automatically run processQueue, and will need to be manually triggered.
