# WAF HTTP API

A CDK construct that fronts an HTTP API with a CloudFront distribution and protects it with AWS WAF.

## Features

* **Enhanced Security:** Protects your HTTP API with AWS WAF rules
* **Global CDN:** Fronts your API with CloudFront for improved performance and availability
* **Origin Verification:** Adds a secret header to ensure requests come through CloudFront
* **Customizable:** Use default WAF rules or provide your own custom rules
* **Easy Integration:** Simple to add to existing AWS CDK stacks

## Installation

### TypeScript/JavaScript

```bash
npm install waf-http-api
```

### Python

<!-- ```bash
pip install waf-http-api
``` -->

## Usage

This example shows how to protect an HTTP API with WAF and CloudFront:

```python
import { Stack, StackProps } from "aws-cdk-lib";
import { HttpApi, HttpMethod } from "aws-cdk-lib/aws-apigatewayv2";
import { HttpLambdaIntegration } from "aws-cdk-lib/aws-apigatewayv2-integrations";
import { NodejsFunction } from "aws-cdk-lib/aws-lambda-nodejs";
import { Runtime } from "aws-cdk-lib/aws-lambda";
import { WafHttpApi } from "waf-http-api";

class MyStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);

    const myLambda = new NodejsFunction(this, "MyApiHandler", {
      runtime: Runtime.NODEJS_18_X,
      handler: "handler",
      entry: "lambda/handler.ts",
    });

    const httpApi = new HttpApi(this, "MyHttpApi", {
      description: "My example HTTP API",
    });

    httpApi.addRoutes({
      path: "/hello",
      methods: [HttpMethod.GET],
      integration: new HttpLambdaIntegration("MyLambdaIntegration", myLambda),
    });

    const protectedApi = new WafHttpApi(this, "ProtectedMyApi", {
      httpApi: httpApi,
      // Optionally, provide custom WAF rules:
      // wafRules: [ ... ],
    });

    new cdk.CfnOutput(this, "ProtectedApiEndpoint", {
      value: protectedApi.distribution.distributionDomainName,
      description: "The CloudFront URL for the protected API endpoint",
    });

    new cdk.CfnOutput(this, "OriginVerificationSecret", {
      value: protectedApi.secretHeaderValue,
      description: "Secret value to verify CloudFront origin requests",
    });
  }
}
```
