如果我们使用 nodejs 和 mysql 创建后端，如何在 react native 中获取数据

Question

So i am very new to react native, but i got little bit understanding in react node express and mysql.let's just say i created backend with node js, express and mysql so how we fetch the data from react native, is it same way like what we do in react?

Answer 1

Same as React. You can just use fetch like this:

import {useEffect} from "react";
const fetchData = () => {
return fetch("...")
 .then((response) => response.json())
 .then((data) => console.log(data));}
 
useEffect(() => {
 fetchData();
 }, []);

Answer 2

Yes, it is the exact same way you'd do it with React, so you most commonly will have 4 options:

1. Axios
2. Fetch API
3. React Query
4. RTK Query (Which I recommend especially if you'll be using redux in your app)
