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.

  expire: 'session'

Database Configuration Options

Option Description Default
expire Database expiration. session (could be never or a time in seconds)

The FunnelQL API is chainable and provides a onload callback.

  .then(function() {
    // database loaded

Writing A Funnel

The Funnel data-set is based on tags that can be set with the following method:


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.
