Goodbye react-query, this new favorite will make real-time data processing a breeze

Want to make front-end and back-end interaction easier? alovajs find out?

Hello everyone! Recently, when I was developing a real-time data display function, I encountered a difficult problem: how to efficiently handle server-pushed events. To be honest, I was almost gray-headed at that time! Just when I was at a loss, I discovered the server send event request strategy of alovajs, which really helped me a lot! This tool not only simplified my code, but also greatly improved the performance of the application. Today, I want to share my experience with you, hoping to give you some inspiration.

What is alovajs? Simply put, it's a next-generation requests tool, but it's more than just an ordinary requests library. Unlike libraries such as react-query and swrjs, alovjs provides a more modern openapi generation solution. It can generate interface calling code, interface typescript type and interface document with one click, greatly shortening the distance between front-end and back-end collaboration. It's like building a highway between the front and back ends, making communication fast and smooth! Even better, it also provides high-quality request strategies for various request scenarios, making it easier to use than other libraries.

If you want to know more about alovajs, it is strongly recommended that you go to the official website: https://alova.js.org. Trust me, you will discover a whole new world of request handling! It's like opening Pandora's box, which contains all kinds of treasures to solve problems.

Now, let us focus on the server send event request strategy. The use of this strategy is very simple, let me demonstrate it to you:

First, we need to import useSSE hook:

import { useSSE } from 'alova/client';

Then, we define a method function:

const method = (value: string) => alova.Get('/api/source', { param: { key: value } });

Next, we can use useSSE:

const { data, eventSource, readyState, onMessage, onError, on, send, close } = useSSE(method, {
  initialData: 'initial-data'
});

Here, we get some very useful variables and functions. data is the received data, readyState represents the connection status, onMessage and onError are used to process messages and errors, send is used to send requests, and close is used to close the connection. It feels like you have a universal remote control that can easily control all data flows!

To start the connection, we just need to call the send function:

send('value');

Handling received messages is also simple:

const unbindMessage = onMessage(({ data }) => {
  console.log(data);
});

If we need to handle errors, we can do this:

const unbindError = onError(({ error }) => {
  console.error('sse error', error);
  close();
});

The best thing is, alovajs also supports custom events:

on('event-name', ({ data }) => {
  console.log(data);
});

Using alovajs's server send event request strategy makes my code more concise and easier to manage. It automatically handles connection management, allowing me to focus on implementing the business logic. To be honest, after using this, I feel that my coding efficiency has at least doubled!

Looking back on the entire usage process, I have to say that alovajs really impressed me. It not only simplifies the use of server send events, but also provides a flexible API to handle various situations. For applications that require real-time data, this is like giving our code a pair of wings, making real-time data processing easy.
