How does it work?

After watching and playing with the app, you can find the steps for developing the features below.

AWS JavaScript SDK

For this app, I have used AWS JavaScript SDK to access AWS services from the browser. AWS Translate is not included in the default build. To use these services in the browser we can use SDK Builder. Go to SDK Builder site, Select Translate and click ‘Build’ to download your customized AWS JS SDK.

Initializing AWS Services

To use AWS services, you should initialize them by calling the methods shown below.
