Verification Code Requests Got You Down? alovajs to the Rescue!

Verification code requests are a common feature in many web applications, but implementing them can be a tedious and repetitive task. Fortunately, alovajs, a next-generation request tool, offers a solution that can streamline this process. The useCaptcha strategy in alovajs provides a convenient way to handle verification code requests, automating the countdown timer and adding customizable features to make your life as a developer much easier.

alovajs is a powerful library that simplifies the request process, offering a more modern approach to API generation compared to libraries like react-query and SWR. While react-query and SWR are great tools, alovajs takes it a step further by generating interface call code, interface TypeScript types, and interface documentation with a single click. This eliminates the need for intermediate API documents, greatly improving collaboration between front-end and back-end teams. Additionally, alovajs provides high-quality request strategies for various scenarios, allowing developers to implement complex request logic with minimal code.

Now, let's dive into the usage of the useCaptcha strategy in alovajs. This strategy automatically handles the countdown timer after a successful verification code request, and you can even customize the countdown duration. Here's an example:

<template>
  <input v-model="mobile" />
  <button
    @click="sendCaptcha"
    :loading="sending"
    :disabled="sending || countdown > 0">
    {{ loading ? 'sending...' : countdown > 0 ? `resend after ${countdown}` : 'send captcha' }}
  </button>
</template>

<script setup>
  import { ref } from 'vue';
  import { apiSendCaptcha } from './api.js';
  import { useCaptcha } from 'alova/client';

  const mobile = ref('');
  const {
    // Sending status
    loading: sending,

    // Call sendCaptcha to request the verification code
    send: sendCaptcha
  } = useCaptcha(() => apiSendCaptcha(mobile.value));
</script>

In this example, the useCaptcha hook is used to handle the verification code request. When the "Send Verification Code" button is clicked, the sendCaptcha function is called, which triggers the API request. After a successful request, the countdown timer automatically starts, and the button's text updates to display the remaining time before the user can request a new code.

But that's not all! You can also customize the countdown duration by passing an initialCountdown option to the useCaptcha hook:

useCaptcha(() => apiSendCaptcha(mobile.value), {
  // ...
  initialCountdown: 20
});

This will set the countdown timer to 20 seconds instead of the default 60 seconds.

In summary, the useCaptcha strategy in alovajs simplifies the process of implementing verification code requests, automating the countdown timer and providing customizable features. By leveraging this powerful tool, you can save time and focus on building the core functionality of your application. Give alovajs a try and see how it can streamline your development workflow!
