Usage

Vue Uploader provides two options:

Option 1) File Upload Button — Try on CodePen

Create a file upload button using the openUploadModal helper:

<template>
  <button @click="uploadFile">Upload a file...</button>
</template>

<script lang="ts">
  import { Uploader } from "uploader";
  import { openUploadModal } from "@upload-io/vue-uploader";
  import type { UploadWidgetConfig, UploadWidgetResult } from "uploader";
  import type { PreventableEvent } from "@upload-io/vue-uploader";

  // Create one instance per app. (Get API keys from Bytescale)
  const uploader = Uploader({
    apiKey: "free"
  });

  // See "customization" below.
  const options: UploadWidgetConfig = {
    multi: true
  };

  export default {
    name: "App",
    methods: {
      uploadFile(event: PreventableEvent) {
        openUploadModal({
          event,
          uploader,
          options,
          onComplete: (files: UploadWidgetResult[]) => {
            if (files.length === 0) {
              alert("No files selected.");
            } else {
              alert(files.map(f => f.fileUrl).join("\n"));
            }
          }
        })
      }
    }
  };
</script>

Option 2) Dropzone — Try on CodePen

Create a file upload dropzone using the UploadDropzone component:

<template>
  <UploadDropzone :uploader="uploader"
                  :options="options"
                  :on-update="onFileUploaded"
                  width="600px"
                  height="375px" />
</template>

<script lang="ts">
import { Uploader } from "uploader";
import { UploadDropzone } from "@upload-io/vue-uploader";
import type { UploadWidgetConfig, UploadWidgetResult } from "uploader";

// One instance per app.
const uploader = Uploader({ apiKey: "free" });

// See "customization" below.
const options: UploadWidgetConfig = {
  multi: true
};

export default {
  name: "App",
  components: {
    UploadDropzone
  },
  data() {
    return {
      uploader,
      options
    };
  },
  methods: {
    onFileUploaded(files: UploadWidgetResult[]) {
      if (files.length === 0) {
        alert("No files selected.");
      } else {
        alert(files.map(f => f.fileUrl).join("\n"));
      }
    }
  }
};
</script>

The Result

The callbacks receive a Array<UploadWidgetResult>:

{
  fileUrl: "https://upcdn.io/FW25...",   // URL to use when serving this file.
  filePath: "/uploads/example.jpg",      // File path (we recommend saving this to your database).

  editedFile: undefined,                 // Edited file (for image crops). Same structure as below.

  originalFile: {
    fileUrl: "https://upcdn.io/FW25...", // Uploaded file URL.
    filePath: "/uploads/example.jpg",    // Uploaded file path (relative to your raw file directory).
    accountId: "FW251aX",                // Bytescale account the file was uploaded to.
    originalFileName: "example.jpg",     // Original file name from the user's machine.
    file: { ... },                       // Original DOM file object from the <input> element.
    size: 12345,                         // File size in bytes.
    lastModified: 1663410542397,         // Epoch timestamp of when the file was uploaded or updated.
    mime: "image/jpeg",                  // File MIME type.
    metadata: {
      ...                                // User-provided JSON object.
    },
    tags: [
      "tag1",                            // User-provided & auto-generated tags.
      "tag2",
      ...
    ]
  }
}

🌐 API Support

🌐 File Management API

Uploading a "Hello World" text file is as simple as:

curl --data "Hello World" \
     -u apikey:free \
     -X POST "https://api.bytescale.com/v1/files/basic"

Note: Remember to set -H "Content-Type: mime/type" when uploading other file types!
