使用内存缓存从后端检索数据
产品详细信息应作为主数据存储在MySQL服务器中。由于将读取大量数据，因此应从Redis或memcahed之类的缓存中读取数据。缓存可以减少MySQL服务器上的负载，并且只有在缓存中找不到数据时才可以访问它（MySQL）。
在MySQL中更改主数据时应更新缓存
编辑：要进一步减少API命中率，请使用会话存储或Redux或Mobx等某种存储管理将数据存储在前端客户端中（仅在数据更改不是至关重要的情况下，例如产品详细信息才能存储）而不是价格，因为它的价格可能会导致失败。

我只是从您的数据库中创建了一个虚拟api，并在react js中实现了这一点。
class Shop extends Component {
constructor(props) {
super(props);
this.state = {
product: []
};
}
async componentDidMount() {
try {
// fetch Api url using `fetch`
const res = await fetch(`http://www.mocky.io/v2/5e0201922f00003688dcd4e5`);
const product = await res.json();
console.log(product);
this.setState({
product: product.data.products
});
} catch (e) {
console.log(e);
}
}
render() {
const { product } = this.state;
if (product.length === 0)
return (
<p>
Loading ...
</p>
);
return (
<ul>
// After Using `map` you can display your all data
{product.map(c => (
<li key={c.id}>{c.name}</li>
))}
</ul>
)}}
export default Shop;
