var obj = {method:'POST'}
fetch('http://localhost:3000/',obj).then(function(){
self.postMessage("check");
})

@jitenderchand1 Hard to help with no detail, but here are some things to check:

• Are you sure you mean localhost? This would mean that you want to access port 3000 on the device
• If this is android and you are running your http server on your machine, have you used adb reverse tcp:3000 tcp:3000 to make it available on the device?
