This app provides real-time bus arrival information on a Amazon's Echo, using WMATA's public API.
It is intended to be deployed as a Lambda function on AWS and uses DynamoDB to store users' home stop ID, based on their Amazon Echo user ID.
Before the initial "Get stop" request is made, a home stop ID must be set, using the SetHomeIntent intent.
Note that you will need the following environment variables to be set for the app to function:
| Variable | Purpose |
|---|---|
WMATA_API_KEY |
Your developer's API key from https://developer.wmata.com/ |
ALEXA_APP_ID |
The ID of your Alexa application. This is found at https://developer.amazon.com/ |
If you save these env vars in your Lambda config, I highly recommend that you use KMS to encrypt them, as they are both potentially sensitive pieces of information.
