# Manage Multimedia Files

If you want to upload files to your Azure Blob Storage Subscriptions enabled in the application settings directly from hooks, this is how you can do it

```javascript
const multimediaService = require("./utils/multimediaService");

//upload from a buffer
await multimediaService.uploadFileBufferToAzureAsync(file);


//upload from a stream
await multimediaService.uploadFileStreamToAzureAsync(stream, file);

//remove a file from azure storage
await multimediaService.deleteFileFromAzureAsync("filename");

```

The `file` param should have the following attributes

```javascript

{
    mimetype, // string | required
    buffer // required if you are using uploadFileBufferToAzureAsync method
    filename
    originalname // required if you are not passing the filename
}

```

The returned object after calling any of those methods will have the next data

```javascript
{
    mimetype, 
    buffer 
    filename
    originalname,
    url, // this will be where you can find your file
    storage //azure by default if enabled
}
```

Additional Parameter for `uploadFileStreamToAzureAsync and` uploadFileBufferToAzureAsync

**omitPrefix** (boolean, optional): When set to `true`, the uploaded file's name will be set to the original name or the provided filename without a timestamp prefix. If set to `false`, the filename will include a timestamp prefix.

```javascript
const multimediaService = require("./utils/multimediaService");
//upload from a buffer 
await multimediaService.uploadFileBufferToAzureAsync(file, true); // omitPrefix 
//upload from a stream 
await multimediaService.uploadFileStreamToAzureAsync(stream, file, true); // omitPrefix 
```

```json
{
    "mimetype": "text/plain",
    "filename": "_file",
    "url": "https://urlazure/app/app/_file",
    "storage": "azure"
}
```
