What is the best way to add an image in a Vue.js project?

Question

What is the best way to add an image in a Vue.js project?

Here is the code snippet from the script section of my Vue component:

While I am able to get all the input field values correctly, the image and video uploads are displaying empty values.

Despite my attempts to address this issue, I have been unsuccessful so far.

        playVideo(url) {
            let video = $('#video-preview').get(0);
            video.preload = 'metadata';
            // Load video in Safari / IE11
            if (url) {
                video.muted = false;
                video.playsInline = true;
                video.play();
            }
        },

        // Read a file input as a data URL.
        readDataUrl(input, callback) {
            if (input.files && input.files[0]) {
                let fileReader = new FileReader();
                fileReader.onload = function () {
                    callback(fileReader.result);
                };
                fileReader.readAsDataURL(input.files[0]);
            }
            else {
                callback(null);
            }
        },

        // Read a file input as an object url.
        readObjectUrl(input, callback) {
            if (input.files && input.files[0]) {
                let fileReader = new FileReader();
                fileReader.onload = function () {
                    let blob = new Blob([fileReader.result], {type: input.files[0].type});
                    let url = URL.createObjectURL(blob);
                    callback(url, blob);
                };
                fileReader.readAsArrayBuffer(input.files[0]);
            }
            else {
                callback(null);
            }

        },

    }

}

I am aiming to upload an image and video file, preview them, and save them as blobs.

However, I am encountering issues with the image and video blobs appearing as empty values.

It seems that in this situation, you may be seeking a solution along the lines of the following:

For instance: uploading an image and previewing it prior to submission

<template>
   <div>
      <img src:"previewImage" class="uploaded-image" />
      <input type="file" accept="image/jpeg" @change=uploadImage>
   </div>
</template>

<script>
    export default {
        name:'imageUpload',
        data(){
            return{
               previewImage:null
            }
        },
        methods:{
            uploadImage(e){
                const image = e.target.files[0];
                const reader = new FileReader();
                reader.readAsDataURL(image);
                reader.onload = e =>{
                    this.previewImage = e.target.result;
                    console.log(this.previewImage);
                };
            }
        }
     }  // added missing closure
</script>

   .uploaded-image{

If you are utilizing the power of axios or fetch to upload files in combination with vue, the process is quite straightforward.

This excerpt is taken directly from my ongoing project where I employ axios for image uploads:

First and foremost, ensure that your input field resembles the following:

<input type="file" accept="image/*" @change="uploadImage($event)" id="file-input">

Next, implement a method similar to the one below:

methods: {

  uploadImage(event) {

    const URL = 'http://foobar.com/upload'; 

    let data = new FormData();
    data.append('name', 'my-picture');
    data.append('file', event.target.files[0]); 

    let config = {
      header : {
        'Content-Type' : 'image/png'
      }
    }

    axios.put(
      URL, 
      data,
      config
    ).then(
      response => {
        console.log('image upload response > ', response)
      }
    )
  }
}

If you're looking to upload an image and preview it prior to submission, there is a simple and effective method available.

<template>
  <input type="file" accept="image/*" @change="onChange" />
  <div id="preview">
    <img v-if="item.imageUrl" :src="item.imageUrl" />
  </div>
</template>


<script>
export default {
  name: 'imageUpload',
  data() {
    return {
      item:{
          //...
          image : null,
          imageUrl: null
      }
    }
  },
  methods: {
    onChange(e) {
      const file = e.target.files[0]
      this.image = file
      this.item.imageUrl = URL.createObjectURL(file)
    }
  }
} 
</script>

Combining insights from various people, here is a summary.

this.image is encoded in base64 format and can be sent to your API seamlessly.

<template>
    <v-file-input
       v-model="file"
       chips
       accept="image/*"
       label="Image"
       @change="onFileChange"
    />
</template>

<script>
export default {
    data: { file: null, image: null },
    methods: {
        onFileChange() {
            const reader = new FileReader()
            reader.readAsDataURL(this.file)
            reader.onload = e => {
                this.image = e.target.result

Combine all elements to view and execute the upload process, remembering to update the URL with your server's destination.

<template>
    <div>
        <img src:"previewImage" class="uploading-image" />
        <input type="file" accept="image/jpeg" @change=uploadImage>
    </div>
</template>

<script>
    export default {
        name:'imageUpload', 
        data(){
            return{
                previewImage:null
            }
        },
        methods:{
            uploadImage(e){
                const image = e.target.files[0];
                const reader = new FileReader();
                reader.readAsDataURL(image);
                reader.onload = e =>{
                    this.previewImage = e.target.result;
                    console.log(this.previewImage);
                };
                
                const URL = 'http://example.com/upload'; 

                let data = new FormData();
                data.append('name', 'my-picture');
                data.append('file', e.target.files[0]); 

                let config = {
                    header : {
                        'Content-Type' : 'image/png'
                    }
                }

                axios.put(URL,data,config).then(response => {
                    console.log('image upload response > ', response)
                })
            }
