如何在使用 ReactJS 下新订单时播放声音

Question

I am building this PWA with ReactJS.

As the title says, I just want to play a sound whenever a new order is placed.

I am using the Context API in order to manage the states.

This is my OrderContext.js where I fetch the orders from the API using React Query.

import React, { createContext } from "react";
import { useQuery } from "react-query";
import apiClient from "../EventService";

export const OrderContext = createContext();

export const OrderProvider = (props) => {
  const fetchOrders = async () => {
    const { data } = await apiClient.getEvents();
    return data;
  };

  let { data: orders, status } = useQuery("orders", fetchOrders, {
    refetchInterval: 15000,
    refetchIntervalInBackground: true,
    notifyOnStatusChange: false,
  });

  return (
    <OrderContext.Provider value={[orders, status]}>
      {props.children}
    </OrderContext.Provider>
  );
};

Then somewhere in my OrdersList.js component, I just use the state and map through it:

{orders.map((order) => (
     <Order key={order.id} order={order} />
))}

And lastly, in my Order.js component is where I check if there is a new order or not:

I am using this function to check if the order has been placed 15 or less minutes ago.

const isNewOrder = (orderCreatedDate) => {
    if (moment().diff(moment(orderCreatedDate)) / 900000 <= 1) {
      return true;
    } else {
      return false;
    }
  };

and then in the in the JSX of the component I simply do this to display a badge on the new orders:

  {isNewOrder(order.date_created) && (
        <Badge style={{ padding: 3 }} content="Nuevo" />
   )}

I am having troubles adding a sound effect to these new orders, I tried using Howler but couldn't make it work properly.

If someone could help me or maybe show me a way to achieve this I would really appreciate. I can provide the full components if needed, let me know. Thanks in advance.

Have a nice day!

I think your best approach is to add a prop to your Order component and check if you are on the order list page or on the order page. If on one single order then you call sound.play , otherwise you do not.

Also, you should use React Howler if you're not already. Regular Howler does not play well (no pun intended) with React.

Finally, you should add a componentWillUnmount function to stop the sound from playing (just call sound.stop() inside componentWillUnmount ).
