When / Conditionals

If you store the builder object in a variable, you can use if and else statements like you would expect.
QueryBuilder
var q = query.from( "posts" );
if ( someFlag ) {
    q.orderBy( "published_date", "desc" );
}
This works, but breaks chainability. To keep chainability you can use the when helper method.
when
Name
Type
Required
Default
Description
condition
boolean
true
​
The condition to switch on.
onTrue
Function
true
​
The callback to execute if the condition is true.  It is passed the builder object as the only parameter.
onFalse
Function
false
function( q ) { return q; }
The callback to execute if the conditions is false.  It is passed the builder object as the only parameter.
The when helper is used to allow conditional statements when defining queries without using if statements and having to store temporary variables.
QueryBuilder
query.from( "posts" )
    .when( someFlag, function( q ) {
        q.orderBy( "published_date", "desc" );
    } )
    .get();
You can pass a third argument to be called in the else case.
QueryBuilder
query.from( "posts" )
    .when(
        someFlag,
        function( q ) {
            q.orderBy( "published_date", "desc" );
        },
        function( q ) {
            q.orderBy( "modified_date", "desc" );
        }
    );
