Increment by N, return current¶
Atomically adds the given value to the current value and returns the updated (current) value of the counter. Multiple concurrent client requests are guaranteed to return updated value.
// *******************************************
// Backendless.Counters approach
// *******************************************
Backendless.Counters.addAndGet( counterName, value )
.then( function( result ) {
})
.catch( function( error ) {
});
// *******************************************
// Backendless.Counters.of() approach
// *******************************************
var counter = Backendless.Counters.of( counterName );
counter.addAndGet( value )
.then( function( result ) {

.catch( function( error ) {

where:
Argument | Description |
---|---|
counterName |
name of the counter to increment. |
value |
number to add to the current counter value |
Example¶
var successCallback = function( response ) {
console.log( "counter value is - " + response );
};
var failureCallback = function( fault ) {
console.log( "error - " + fault.message );
};
// ************************************************
// Backendless.Counters approach
// ************************************************
Backendless.Counters.addAndGet( "my counter", 1000 )
.then( successCallback )
.catch( failureCallback );
// ************************************************
// Backendless.Counters.of() approach
// ************************************************
var myCounter = Backendless.Counters.of( "my counter" );
myCounter.addAndGet( 1000 )
.then( successCallback )
.catch( failureCallback );
