JavaScript

If you are planning to use JavaScript to develop your application, you'll need to install (or update) the latest version of the Client SDK.

Create a new folder in your project directory and change into it.

mkdir app-to-phone cd app-to-phone

Then run the following command:

npm init npm install @vonage/client-sdk -s

This will install the Client SDK into the node_modules directory within your project folder.

If you already have the Client SDK installed the above command will upgrade your Client SDK to the latest version.
