javascript - npm svn-interface node programming- multiple method piping -

i'm writing process using npm svn-interface.

i have file want to:

1. add svn
2. commit svn (with message)

3. update directory svn.

   // check file svn svn.add(tmp, options, function(){     // do here? });  options.message = "adding test version svn"; svn.commit(tmp, options, function(){     // do here? });  svn.update(tmp, options, function(){     // do here? }); 

when run above, file gets added, not committed.

what can make these command play nicely, , in order?

update

ok, tried code below, still, first task run:

        // array hold async tasks         var asynctasks = [];          asynctasks.push(function(callback){             // call async function, save() db             svn.add(testfile, options, callback);         });         asynctasks.push(function(callback){             options.message = "adding test version svn";             svn.commit(testfile, options, callback);         });         asynctasks.push(function(callback){             options.message = "adding test version svn";             svn.update(testfile, options, callback);         });          async.parallel(asynctasks, function(){             // tasks done             console.log('finished');          });
