If state is true than run this component

ComponentDidMount will update my component every second(with setInterval) but I want it to update only if my state is true ,is something of that sort is possible?

You could use setTimeout instead and renew timeout only if "state is true"

componentDidMount() {
  this.start()
}

componentWillUnmount() {
  this.stop()
}

start() {
  this.timeoutId = setTimeout(() => {
     doSmthUseful();

     if(state is true) { // whatever you mean by "if my state is true"
         this.start()
     }
  }, 1000)
}

stop() {
   clearTimeout(this.timeoutId)
}
