Javascript – Async.eachseries In Node.js

javascript – async.eachSeries in node.js

Assuming test accepts a callback, we will use mapSeries to realize that.

async.mapSeries(information, operate(file, outerCB) {
  var all = fs.readdirsync(./0);
  async.mapSeries(all, operate(merchandise, cb){
      test(merchandise, cb);
  }, outerCB);
}, operate(err, outcomes) {
  // This is known as when everythings accomplished
});

Outer loop must be async additionally. One of the the strategies is to make use of 2 eachSeries loops or outer loop could be in parallel (every) if the information dont need to be processed in sequence:

var async = require(async);

async.eachSeries(information, operate(file, outCb) 
{
  var all = fs.readFileSync(file);

  async.eachSeries(all, operate(merchandise, inCb) 
  {
    test(merchandise);
    inCb(null);  // inside callback
  }, 
  operate(err) 
  {
    outCb(null);  // outer callback
  });
},
operate(err) 
{
  console.log(all accomplished!!!);
});
