## Installation
Install via NPM:
```shell
npm install @bytescale/upload-widget-vue
```
Or via YARN:
```shell
yarn add @bytescale/upload-widget-vue
```
Or via a `
```
## Usage
### Option 1) File Upload Button — [Try on CodePen](https://codepen.io/bytescale/pen/yLpvYew?editors=1000)
Create a file upload button using the `openUploadModal` helper:
```html
```
### Option 2) Dropzone — [Try on CodePen](https://codepen.io/bytescale/pen/RwJvpKG?editors=1000)
Create a file upload dropzone using the `UploadDropzone` component:
```html
```
> **Special behaviour for dropzones:**
>
> `on-complete` only fires if `showFinishButton = true` (when the user clicks "Finish").
>
> `on-update` must be used when `showFinishButton = false`.
>
> Default value: `showFinishButton = false`
## Result
The callbacks receive a `Array`:
```javascript
{
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 element.
size: 12345, // File size in bytes.
lastModified: 1663410542397, // Epoch timestamp of when the file was uploaded or updated.

## Authentication
Bytescale supports two types of authentication:
### API Keys
The Bytescale Upload Widget uses the `apiKey` parameter to authenticate with [Bytescale](https://www.bytescale.com/).
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](https://www.bytescale.com/docs/sdks/javascript)).
- 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
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 ``, `
