How can I implement file upload completion in Vue.js?

You can use the Vue.js framework along with libraries like Axios to handle file uploads. Would you like a code example?

Yes, please provide a code example for file upload.

Here's a simple example:

<template>
  <input type="file" @change="onFileChange" />
  <button @click="uploadFile">Upload</button>
</template>

<script>
export default {
  data() {
    return {
      file: null,
    };
  },
  methods: {
    onFileChange(event) {
      this.file = event.target.files[0];
    },
    async uploadFile() {
      const formData = new FormData();
      formData.append('file', this.file);
      await axios.post('/upload', formData);
      alert('File uploaded successfully!');
    },
  },
};

This code allows users to select a file and upload it.

How do I handle upload progress and completion notifications?

You can use Axios' onUploadProgress to track the upload progress. Here's how:

async uploadFile() {
  const formData = new FormData();
  formData.append('file', this.file);
  await axios.post('/upload', formData, {
    onUploadProgress: progressEvent => {
      const percentCompleted = Math.round((progressEvent.loaded * 100) / progressEvent.total);
      console.log(`Upload Progress: ${percentCompleted}%`);
    }
  });
  alert('File uploaded successfully!');
}
