Axios is out? You must try this magical retry strategy

Hello everyone! When I was developing a project recently, I discovered a super practical feature - the automatic retry request strategy. Do you know, this little function really helps me a lot! Every time I fail to handle a network request, I always have to write a bunch of repeated code, which is really annoying. But with this strategy, everything has become so easy! Let me introduce it to you today.

alovajs: More than just a regular requests library

When it comes to automatic retry request strategies, we have to mention the artifact alovajs. alovajs is a brand new request tool, it is not just an ordinary request library. It provides a more modern openapi generation solution, which can generate interface calling code, TypeScript types and interface documents with one click, eliminating the need for intermediate api documentation and greatly shortening the distance between front-end and back-end collaboration.

The best thing is that alovajs also provides high-quality request strategies for various request scenarios, including the automatic retry strategy we are going to talk about today. These strategies include stateful data, specific events and actions, and are smoother to use than react-query and swrjs. You only need a small amount of code to implement requests in specific scenarios, greatly improving development efficiency!

Want to know more about alovajs? Go to the official website: https://alova.js.org. I believe you will be amazed by its powerful functions!

Automatic retry strategy

Okay, let’s take a look at how powerful this automatic retry strategy is.

import { useRetriableRequest } from 'alova/client';

const {
  loading,
  data,
  error,
  onError,
  onRetry,
  onFail,
  onSuccess,
  onComplete
} = useRetriableRequest(request);

See, it’s that simple! Not only can you get the loading status, response data and error information of the request, but you can also bind various event callbacks. This is much more convenient than writing it ourselves, right?

Custom retries

Sometimes we want the request to be automatically retried several times. This is also easy to achieve:

const { send } = useRetriableRequest(request, {
  retry: 5
});

Set the maximum number of retries to 5, it’s that simple. Of course, if you want to control the retry logic more flexibly, you can also pass in a function to dynamically determine.

Set retry delay

Sometimes we want a certain delay between each retry, which is also easy to configure:

useRetriableRequest(request, {
  backoff: {
    delay: 2000,
    multiplier: 2
  }
});

After setting like this, the first retry delay is 2 seconds, the second time is 4 seconds, the third time is 8 seconds, and so on. You can even add random jitter to make retries more "random".

Manually stop retry

If you need to manually stop retrying under certain circumstances, it is also very simple:

const { stop } = useRetriableRequest(request);

const handleStop = () => {
  stop();
};

Summarize

In general, the automatic retry strategy of alovajs is really a super practical function! It not only greatly simplifies the code of retry logic, but also provides a variety of flexible configuration options, which greatly improves development efficiency. .

The most important thing is that it can help us solve many pain points in traditional request processing, such as retry number control, delay time setting, etc. These are very common requirements in daily development. With this strategy, we no longer need to implement them ourselves.

Have you ever encountered similar problems during development? You might as well try the automatic retry strategy of alovajs, maybe it can help you. If you are already using it, please share your experience in the comment area! Let us discuss and make progress together!

Remember, technology is constantly advancing, and we must keep up with the pace. Only by maintaining a passion for learning can you gain a firm foothold in this rapidly developing industry. That’s it for today’s sharing, I hope it will be helpful to everyone. If you find it useful, don’t forget to give it a like! See you next time!
