Question

Is there any way to skip the calls in serial or parallel calls flow.

var flow = require('flow');

    flow.exec(
       function(){
         //Execute
       },
       function(){
         //Skip
       },
       function(){
        //Exec
       },
       function(){
         //Done
       }
    );

Answer 1

Just create a condition inside the method that you might want to skip and trigger the callback immediately

flow.exec(
function taskOne() {
   // long task 
   fs.readFile(path, 'utf8', this);
},
function taskTwo() {
  if (condition) {
    return this(); // trigger the callback.
  }
},
function lastTask() {
   console.log("done");
}
);
