Javascript API
Start by installing the FunnelQL Javascript library (see Installation).

Loading the FunnelQL database

Funnel Query Language is based on a IndexedDB database that can persist or expire with the browser session. You can configure the database using the init method.
$FQL.init({
expire: 'session'
});

expire
Database expiration.
session (could be never or a time in seconds)
The FunnelQL API is chainable and provides a onload callback.
$FQL.on('load')
.then(function() {
// database loaded
});

Writing A Funnel

The Funnel data-set is based on tags that can be set with the following method:
$FQL.tag('tag-name');
During navigation, URLs are automatically registered. The following method can be used to manually register a navigation:
$FQL.nav('URL or path/');

Querying A Funnel

The following method can be used to perform a query based on a Funnel Query string or JSON:
$FQL.query( "funnel query" ).then(function(result) {
// result = true/false (boolean)
});
The following method can be used to parse a Funnel Query string into JSON:
$FQL.parse( "funnel query" ).then(function(json) {
// json
});
The following method can be used to perform an action as soon as a Funnel Query string or JSON matches the path of the visitor:
$FQL.on( "funnel query" ).then(function(result) {
// result = true
});
Alternatively, the on method accepts a callback instead of a promise and multiple queries as a Array.
$FQL.on( [ "funnel query 1", "funnel query 2" ], function(result, fql) {
// result = true
// fql = funnel query string
});
The library can provide detailed debug information including Performance API timings in the browser console. The following method can be used to enable debug mode or to retrieve it's status.
$FQL.debug(true);
