Install via NPM:
npm install @bytescale/upload-widget-vue
Or via YARN:
yarn add @bytescale/upload-widget-vue
Or via a <script> tag:
<script src="https://js.bytescale.com/upload-widget-vue/v4"></script>
Create a file upload button using the openUploadModal helper:
<template>
<button @click="uploadFile">Upload a file...</button>
</template>
<script lang="ts">
import { openUploadModal } from "@bytescale/upload-widget-vue";
import type { UploadWidgetConfig, UploadWidgetResult } from "@bytescale/upload-widget";
import type { PreventableEvent } from "@bytescale/upload-widget-vue";
// Full Configuration:
// https://www.bytescale.com/docs/upload-widget#configuration
const options: UploadWidgetConfig = {
apiKey: "free", // Get API keys from: www.bytescale.com
maxFileCount: 10
};
export default {
name: "App",
methods: {
uploadFile(event: PreventableEvent) {
openUploadModal({
event,
options,
onComplete: (files: UploadWidgetResult[]) => {
if (files.length === 0) {
alert("No files selected.");
} else {
alert(files.map(f => f.fileUrl).join("\n"));
}
}
})
}
}
};
</script>
Create a file upload dropzone using the UploadDropzone component:
<template>
<UploadDropzone :options="options"
:on-complete="onFilesUploaded"
:on-update="onFileListChanged"
width="600px"
height="375px" />
</template>
<script lang="ts">
import { UploadDropzone } from "@bytescale/upload-widget-vue";
import type { UploadWidgetConfig, UploadWidgetResult, UploadWidgetOnUpdateEvent } from "@bytescale/upload-widget";
// Full Configuration:
// https://www.bytescale.com/docs/upload-widget#configuration
const options: UploadWidgetConfig = {
apiKey: "free", // Get API keys from: www.bytescale.com
maxFileCount: 10,
showFinishButton: true
};
export default {
name: "App",
components: {
UploadDropzone
},
data() {
return {
options
};
},
methods: {
onFileListChanged({ uploadedFiles, pendingFiles, failedFiles }: UploadWidgetOnUpdateEvent) {
const uploadedFileUrls = uploadedFiles.map(x => x.fileUrl).join("\n");
console.log(uploadedFileUrls);
},
onFilesUploaded(files: UploadWidgetResult[]) {
if (files.length === 0) {
alert("No files selected.");
} else {
alert(files.map(f => f.fileUrl).join("\n"));
}
}
}
};
</script>
Special behaviour for dropzones:
on-completeonly fires ifshowFinishButton = true(when the user clicks "Finish").
on-updatemust be used whenshowFinishButton = false.Default value:
showFinishButton = false
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).
accountId: "FW251aX", // Bytescale account the file was uploaded to.
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.

}
}

Bytescale provides a wide range of File Management APIs:
Bytescale also provides real-time Media Processing APIs:
Here's an example using a photo of Chicago:
https://upcdn.io/W142hJk/raw/example/city-landscape.jpg
Using the Image Processing API, you can produce this image:
https://upcdn.io/W142hJk/image/example/city-landscape.jpg
?w=900
&h=600
&fit=crop
&f=webp
&q=80
&blur=4
&text=WATERMARK
&layer-opacity=80
&blend=overlay
&layer-rotate=315
&font-size=100
&padding=10
&font-weight=900
&color=ffffff
&repeat=true
&text=Chicago
&gravity=bottom
&padding-x=50
&padding-bottom=20
&font=/example/fonts/Lobster.ttf
&color=ffe400
Bytescale supports two types of authentication:
The Bytescale Upload Widget uses the apiKey parameter to authenticate with Bytescale.
With API key auth, the requester has access to the resources available to the API key:
Secret API keys (secret_***) can perform all API operations (see: Bytescale JavaScript SDK).
Public API keys (public_***) can perform file uploads and file downloads only. File overwrites, file deletes, and all other destructive operations cannot be performed using public API keys.
You must always use public API keys (e.g. public_***) in your client-side code.
Each API key can have its read/write access limited to a subset of files/folders.
JWTs are optional.
With JWTs, users can download private files directly via the URL, as authentication is performed implicitly via a session cookie or via an authorization header if service workers are enabled (see the serviceWorkerScript param on the AuthManager.beginAuthSession method). This allows the browser to display private files in <img>, <video>, and other elements.
With JWTs, users can upload files to per-user folders. This is because the permissions in the JWT's payload can be generated at runtime. The Bytescale Upload Widget internally uses the Bytescale JavaScript SDK to perform file uploads: the Bytescale JavaScript SDK handles the JWT refresh process with your API, requesting new JWTs when required, and includes your JWTs in all subsequent requests to the Bytescale API.

The Bytescale JavaScript SDK exports a UrlBuilder to construct URLs from filePaths:
import { UrlBuilder } from "@bytescale/sdk";
Recommended: you should always save filePaths to your DB instead of fileUrls.
To get the URL for the uploaded image /example.jpg in its original form, use the following:
// Returns: "https://upcdn.io/1234abc/raw/example.jpg"
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.jpg"
});
To resize the uploaded image /example.jpg to 800x600, use the following:
// Returns: "https://upcdn.io/1234abc/image/example.jpg?w=800&h=600"
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.jpg",
options: {
transformation: "image",
transformationParams: {
w: 800,
h: 600
}
}
});
To transcode the uploaded video /example.mov to MP4/H.264 in HD, use the following:
// Returns: "https://upcdn.io/1234abc/video/example.mov?f=mp4-h264&h=1080"
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.mov",
options: {
transformation: "video",
transformationParams: {
f: "mp4-h264",
h: 1080
}
}
});
To transcode the uploaded audio /example.wav to AAC in 192kbps, use the following:
// Returns: "https://upcdn.io/1234abc/audio/example.wav?f=aac&br=192"
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.wav",
options: {
transformation: "audio",
transformationParams: {
f: "aac",
br: 192
}
}
});
To extract the file document.docx from the uploaded ZIP file /example.zip:
// Returns: "https://upcdn.io/1234abc/archive/example.zip?m=extract&artifact=/document.docx"
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.zip",
options: {
transformation: "archive",
transformationParams: {
m: "extract"
},
artifact: "/document.docx"
}
});
