How to start second thread in ionic


how we can start second process in ionic because i want to start some calculation in background without effecting user interface tread


Something like…

      return new Promise((resolve, reject) {
         //pretend a long-running task
         setTimeout(() => { resolve(true); }, 5000);

Then call from your code

    this.doSomething().then(truthy => { console.log('finished'); });


please follow attached link , i want implement same


I used this plugin in the past…

It does have a cost - but works!


This looks promising


I think when you say background you mean when the app is closed or hidden…

Refer to my previous two posts.


NO I want to run two separate thread


The thing you are looking for is web worker which runs on separate thread in background without affecting the main thread ui.
