Installation
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>
Usage
Option 1) File Upload Button โ 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 { openUploadModal } from "@bytescale/upload-widget-vue";
import type { UploadWidgetConfig, UploadWidgetResult } from "@bytescale/upload-widget";
import type { PreventableEvent } from "@bytescale/upload-widget-vue";
const options: UploadWidgetConfig = {
apiKey: "free",
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-update="onFileUploaded"
width="600px"
height="375px" />
</template>
<script lang="ts">
import { UploadDropzone } from "@bytescale/upload-widget-vue";
import type { UploadWidgetConfig, UploadWidgetResult } from "@bytescale/upload-widget";
const options: UploadWidgetConfig = {
apiKey: "free",
maxFileCount: 10
};
export default {
name: "App",
components: {
UploadDropzone
},
data() {
return {
options
};
},
methods: {
onFileUploaded(files: UploadWidgetResult[]) {
if (files.length === 0) {
alert("No files selected.");
} else {
alert(files.map(f => f.fileUrl).join("\n"));
}
}
}
};
</script>
Result
The callbacks receive a Array<UploadWidgetResult>
:
{
fileUrl: "https://upcdn.io/FW25...",
filePath: "/uploads/example.jpg",
editedFile: undefined,
originalFile: {
fileUrl: "https://upcdn.io/FW25...",

๐ API Support
๐ File Management APIs
Bytescale provides a wide range of File Management APIs:
๐ Media Processing APIs (Image/Video/Audio)
Bytescale also provides real-time Media Processing APIs:
Image Processing API (Original Image)
Here's an example using a photo of Chicago:
https://upcdn.io/W142hJk/raw/example/city-landscape.jpg
Image Processing API (Transformed Image)
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
Authorization
Bytescale supports two types of authorization:
API Keys
The Bytescale Upload Widget uses the apiKey
parameter to authenticate with the Bytescale API.
With API key auth, the requester has access to the resources available to the API key:
-
Secret API keys (secret_***
) have access to all API endpoints (see the Bytescale JavaScript SDK).
-
Public API keys (public_***
) have access to file upload, file download, and file listing API endpoints. File overwrites, file deletes, and all other destructive operations cannot be performed using public API keys. File listing is also disabled by default (but can be changed in the API key's settings).
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.
JWT Cookies
JWT cookies are optional.
With JWT cookies, the user can download private files directly via the URL, as authorization is performed implicitly via a session cookie. This allows the browser to display private files in <img>
and <video>
elements.
With JWT cookies, the user can also upload files to locations that aren't otherwise permitted by the API key, but are permitted by the JWT's payload. This is because the Bytescale Upload Widget internally uses the Bytescale JavaScript SDK to perform file uploads, and the Bytescale JavaScript SDK automatically injects the user's JWT into all API requests once the AuthManager.beginAuthSession
method has been called.
Note: when using JWT cookies to download files, the ?auth=true
query parameter must be added to the URL.

and JWT cookies ยป
UrlBuilder
The Bytescale JavaScript SDK exports a UrlBuilder
to construct URLs from filePath
values:
import { UrlBuilder } from "@bytescale/sdk";
Recommended: you should always save filePath
values to your DB instead of fileUrl
values.
Raw Files
To get the URL for the uploaded image /example.jpg
in its original form, use the following params:
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.jpg"
});
Images
To resize the uploaded image /example.jpg
to 800x600, use the following params:
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.jpg",
options: {
transformation: "image",
transformationParams: {
w: 800,
h: 600
}
}
});

Videos
To transcode the uploaded video /example.mov
to MP4/H.264 in HD, use the following params:
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.mov",
options: {
transformation: "video",
transformationParams: {
f: "mp4-h264",
h: 1080
}
}
});

Audio
To transcode the uploaded audio /example.wav
to AAC in 192kbps, use the following params:
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.wav",
options: {
transformation: "audio",
transformationParams: {
f: "aac",
br: 192
}
}
});

Archives
To extract the file document.docx
from the uploaded ZIP file /example.zip
, use the following params:
UrlBuilder.url({
accountId: "1234abc",
filePath: "/example.zip",
options: {
transformation: "archive",
transformationParams: {
m: "extract"
},
artifact: "/document.docx"
