i found an alternate method . we can use javascript on server side to transmit data using MQTT
but is it possible with the device(arduino or esp8266 as server) serve a html page as well as transmit data to external server using MQTT

I see no reason why you cannot use a mqtt pub library, what exactly is the problem here?

when I add MQTT for publishing a topic it doesnt work (only mqtt part)
can you give suggestions to make it work?
how wifimanger and espclient and pubsubclient are connected?
