# Nexmo Voice API Demo with AWS CDK
This repo sets up a simple nexmo application that will answer phone calls and accept user input, and respond according to the input
## Structure
```
├── index.ts: defines the cdk stack
└── lambda: contains the lambda functions along with any dependencies.
│ This dir will be zipped and deployed to different lambdas with different handlers
├── answer.ts: called when a phone call is received to return the ncco
├── input.ts: called when a user makes an input, returns a new ncco based on input
└── voice-event.ts: called for generic events which don't have a specific handler
```
## Dependencies
* AWS CLI installed and configured with your account credentials
* Setup: https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html
* Configure: https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html
* CDK & Typescript global install
```
npm i -g aws-cdk typescript
```
* nexmo account, application credentials, and phone number
https://dashboard.nexmo.com/voice/create-application
## Install
```
yarn
```
## Configure nexmo application
Copy the file `.env-template` to `.env` and replace variables with your nexmo credentials. Leave the variable `ENDPOINT` for now, we'll get it from `yarn deploy` output.
## Run
* `yarn watch` starts typescript compiler and watch for changes
* `yarn deploy` deploys the CDK stack to your AWS account, this will output the gateway endpoint like
```
Outputs:
VAPIStack.VAPIGatewayEndpointXXXXX = https://{some-id}.execute-api.{region}.amazonaws.com/prod/
```
you'll then copy this url (without the trailing slash) to your `.env` file under `ENDPOINT`
* `yarn setup` configures your nexmo app to use the AWS stack endpoint for webhooks
