Your effect is triggered based on the "shopUsers" prop, which itself triggers a redux action that updates the "shopUsers" prop and thats why it keeps infinitely firing.

I think what you want to optimize is the rendering of your component itself, since you're already using redux, I'm assuming your props/state are immutable, so you can use React.memo to re-render your component only when one of its props change.

Also you should define your state/props variable outside of your hooks since they're used in the scope of the entire function like so.

In your case, if you pass an empty array as a second param to memo, then it will only fire on ComponentDidMount, if you pass null/undefined or dont pass anything, it will be fired on ComponentDidMount + ComponentDidUpdate, if you want to optimise it that even when props change/component updates the hook doesn't fire unless a specific variable changes then you can add some variable as your second argument

  const [isLoading, setLoading] = useState(false);
  const { getStoreUsers, shopUsers } = props;
  useEffect(() => {
    getStoreUsers().then(() => {
    }).catch((err) => {
  }, []);


You can make a custom hook to do what you want:

In this example, we replace the last element in the array, and see the output in the console.

import React, { useState, useEffect, useRef } from "react";
import ReactDOM from "react-dom";
import { isEqual } from "lodash";

const usePrevious = value => {
  const ref = useRef();
  useEffect(() => {
    ref.current = value;
  return ref.current;

const App = () => {
  const [arr, setArr] = useState([2, 4, 5]);
  const prevArr = usePrevious(arr);

  useEffect(() => {
    if (!isEqual(arr, prevArr)) {
      console.log(`array changed from ${prevArr} to ${arr}`);
  }, [prevArr]);

  const change = () => {
    const temp = [...arr];

  return (
      <button onClick={change}>change last array element</button>

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
