## Overview

This AWS Solutions Konstruk implements an Amazon API Gateway REST API connected to an AWS Lambda function pattern.

Here is a minimal deployable pattern definition:

```javascript
const { ApiGatewayToLambda } = require('@aws-solutions-konstruk/aws-apigateway-lambda');

new ApiGatewayToLambda(stack, 'ApiGatewayToLambdaPattern', {
    deployLambda: true,
    lambdaFunctionProps: {
        runtime: lambda.Runtime.NODEJS_10_X,
        handler: 'index.handler',
        code: lambda.Code.asset(`${__dirname}/lambda`)
    }
});

```

## Initializer

```text
new ApiGatewayToLambda(scope: Construct, id: string, props: ApiGatewayToLambdaProps);
```

*Parameters*

* scope [`Construct`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_core.Construct.html)
* id `string`
* props [`ApiGatewayToLambdaProps`](#pattern-construct-props)

## Pattern Construct Props

| **Name**     | **Type**        | **Description** |
|:-------------|:----------------|-----------------|
|deployLambda|`boolean`|Whether to create a new Lambda function or use an existing Lambda function. If set to false, you must provide an existing function for the `existingLambdaObj` property.|
|existingLambdaObj?|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|An optional, existing Lambda function. This property is required if `deployLambda` is set to false.|
|lambdaFunctionProps?|[`lambda.FunctionProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.FunctionProps.html)|Optional user-provided props to override the default props for the Lambda function. This property is only required if `deployLambda` is set to true.|
|apiGatewayProps?|[`api.LambdaRestApiProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-apigateway.LambdaRestApi.html)|Optional user-provided props to override the default props for the API.|

## Pattern Properties

| **Name**     | **Type**        | **Description** |
|:-------------|:----------------|-----------------|
|lambdaFunction()|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|Returns an instance of the Lambda function created by the pattern.|
|restApi()|[`api.LambdaRestApi`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-apigateway.LambdaRestApi.html)|Returns an instance of the API Gateway REST API created by the pattern.|
