Buy me a coffee

The inspiration behind this function came from a need to perform an action after a script created and rendered new DOM content - (Typical in React), as the rendering process takes a little bit of time, a racy function was born, enjoy!

Mission - Keep searching for a x query (DOM node) for x amount of time, at x intervals and once found, perform x action, if query not successful run `x`` callback.

---

• query - query string - (A string containing one selectors to match. This string must be a valid CSS selector string),
• callback - callback function to execute once query has been validated as a truthy value,
• interval - how often the validate the query, defaults to 1000ms,
• timeout - determines when your interval loop will terminate, defaults to 10000ms,
• errorCallback - function called when search query time's out

---

• clearTimers For those individuals using React, our function returns a method (clearTimers) which you can call if you want to clear the timers that are initiated during the functions lifecycle, this typically would be needed if and when your React component un-mounts but the timers are still running in the background.

  Simply call this method in the return statement of your useEffect hooks

• _timeout Timeout instance ( type NodeJS.Timeout )

• _interval Interval instance ( type NodeJS.Timeout )

---

const query = "#myQuery";  
const callback = () => console.log("Found it!") 
const errorCallback = () => console.log("Not Found!") 
const { clearTimers, _timeout, _interval } = raceSeekAndExecute({query, callback, errorCallback})

---

useEffect(() => {
    const query = "#myQuery";  
    const callback = () => console.log("Found it!") 
    const errorCallback = () => console.log("Not Found!") 
    const { clearTimers, _timeout, _interval } = raceSeekAndExecute({query, callback, errorCallback})
    return () => clearTimers()
}, []);
