How to do API call in React?
To do API call in React, we call the useEffect hook.
For instance, we write
import React, { useState, useEffect } from "react";
const Comp = () => {
//...
useEffect(() => {
fetchDataFromBackend();
}, []);
//...
};
to call useEffect in the Comp component with a callback that calls fetchDataFromBackend to make the request to the API we want.
We call useEffect with an empty array so that the callback only runs when the component mounts.
