Introduction to the Upload widget
 0:05 |
Cloudinary has many ways to upload files to your Media Library, enabling you to take advantage of Cloudinary's extensive features and capabilities. In a Remix app you can use the Upload widget as a quick and easy way to provide a full upload experience. |
Add the Upload widget script to your Remix app
| 0:28 |
Start with a basic Remix application and add the Upload widget JavaScript file. Paste the code, which you can find in the Upload widget documentation, into the <body> section of root.jsx. |
Configure the Upload widget
| 1:20 |
Create a loader function to set up environment variables for the configuration data required for the Upload widget: the cloud name of your account (which you can find in the Console Dashboard) and the name of an upload preset (see the next step). Set the environment variables in a .env file. |
Create an upload preset
| 1:55 |
In your Cloudinary Console, navigate to Settings > Upload > Upload presets to create a new unsigned upload preset. Give the preset a name and make sure to change the Signing mode to unsigned, then save the upload preset. |
Add a new component for the Upload widget
| 2:27 |
Add a new file called index.jsx in app/components/UploadWidget in which you can create a component for the Upload widget. After defining your component as UploadWidget, you can import this component into your main route. |
Initialize the Upload widget
| 3:10 |
Back in the component code, retrieve the environment variables using the useMatches function. Pass these to the createUploadWidget method to initialize the widget. Let the callback function log the result and any error to the console. Instantiate the widget using useEffect and maintain a reference to the created widget using useRef. |
Add a button to open the Upload widget
| 4:58 |
Render a simple button to open the Upload widget when clicked. |
Test it out
| 5:15 |
Open the app in a browser. Click the button to open the Upload widget and upload a file to your Cloudinary product environment. See the response logged in the console. |
