Download & Upload Progress

useHook provides downloading and uploading for displaying progress information directly in the view.

Download progress

For performance reasons, there is no progress information in downloading by default. You need to set enableDownload of the method instance to true, which will continuously update the downloading status during the download process.

vue

<template>
  <div>File size: {{ downloading.total }}B</div>
  <div>Downloaded: {{ downloading.loaded }}B</div>
  <div>Progress: {{ downloading.loaded / downloading.total * 100 }}%</div>
</template>

<script setup>
  const downloadGetter = alovaInstance.Get('/todo/downloadfile', {
    // Start download progress
    enableDownload: true
  });
  const { downloading } = useRequest(downloadGetter);
</script>

react

const downloadGetter = alovaInstance.Get('/todo/downloadfile', {
  // Start download progress
  enableDownload: true
});

const App = () => {
  const { downloading } = useRequest(downloadGetter);
  return (
    <>
      <div>File size: {downloading.total}B</div>
      <div>Downloaded: {downloading.loaded}B</div>
      <div>Progress: {(downloading.loaded / downloading.total) * 100}%</div>
    </>
  );
};

svelte

<script>
  const downloadGetter = alovaInstance.Get('/todo/downloadfile', {
    // Start download progress
    enableDownload: true
  });
  const { downloading } = useRequest(downloadGetter);
</script>

<div>File size: {$downloading.total}B</div>
<div>Downloaded: {$downloading.loaded}B</div>
<div>Progress: {$downloading.loaded / $downloading.total * 100}%</div>

vue options

<template>
  <div>File size: {{ file.downloading.total }}B</div>
  <div>Downloaded: {{ file.downloading.loaded }}B</div>
  <div>Progress: {{ file.downloading.loaded / file.downloading.total * 100 }}%</div>
</template>

<script>
  import { useRequest } from 'alova';
  import { mapAlovaHook } from '@alova/vue-options';

  const downloadGetter = alovaInstance.Get('/todo/downloadfile', {
    // Start download progress
    enableDownload: true
  });
  export default {
    mixins: mapAlovaHook(function () {
      return {
        file: useRequest(downloadGetter)
      };
    })
  };
</script>

Upload progress

Using the upload progress status is the same as using the download progress. First enable the upload progress information through enableUpload, and then receive it by receiving the uploading responsive state.

vue

<template>
  <div>File size: {{ uploading.total }}B</div>
  <div>Uploaded: {{ uploading.loaded }}B</div>
  <div>Progress: {{ uploading.loaded / uploading.total * 100 }}%</div>
</template>

<script setup>
  const uploadPoster = alovaInstance.Post('/todo/uploadfile', formData, {
    // Start upload progress
    enableUpload: true
  });
  const { uploading } = useRequest(uploadPoster);
</script>

react

const uploadPoster = alovaInstance.Post('/todo/uploadfile', formData, {
  // Start upload progress
  enableUpload: true
});

const App = () => {
  const { uploading } = useRequest(uploadPoster);
  return (
    <>
      <div>File size: {uploading.total}B</div>
      <div>Uploaded: {uploading.loaded}B</div>
      <div>Progress: {(uploading.loaded / uploading.total) * 100}%</div>
    </>
  );
};

svelte

<script>
  const uploadPoster = alovaInstance.Post('/todo/uploadfile', formData, {
    // Start upload progress
    enableUpload: true
  });
  const { uploading } = useRequest(uploadPoster);
</script>

<div>File size: {$uploading.total}B</div>
<div>Uploaded: {$uploading.loaded}B</div>
<div>Progress: {$uploading.loaded / $uploading.total * 100}%</div>

vue options

<template>
  <div>File size: {{ file.uploading.total }}B</div>
  <div>Uploaded: {{ file.uploading.loaded }}B</div>
  <div>Progress: {{ file.uploading.loaded / uploading.total * 100 }}%</div>
</template>

<script>
  const uploadPoster = alovaInstance.Post('/todo/uploadfile', formData, {
    // Start upload progress
    enableUpload: true
  });

  export default {
    mixins: mapAlovaHook(function () {
      return {
        file: useRequest(uploadPoster)
      };
    })
  };
</script>
