We are converting from a REST API to an HTTP API because you said that REST API cannot send muti-valued headers and we are implementing HttpOnly Cookies and we want to be able to get the username from the server. The application will also have to send text to the server and have it store the text in user-private S3 bucket paths in the bucket created in the CDK. It will also have a function for the user to retrieve those text strings.

We are using HttpOnly Cookies as a method to prevent XSS vulnerabilities.

Currently, I am getting this error:

Type 'LambdaIntegration' is missing the following properties from type 'HttpRouteIntegration': id, _bindToRoute, completeBindts(2739)
route.d.ts(100, 14): The expected type comes from property 'integration' which is declared here on type 'AddRoutesOptions'

On this line of code:

  httpApi.addRoutes({
   path: ENDPOINTS.api.TokenHandler,
   methods: [HttpMethod.GET],
   integration: tokenHandlerIntegration,
  })

The error you're encountering is because you're trying to use LambdaIntegration from the REST API Gateway (aws-apigateway) module with an HTTP API Gateway (aws-apigatewayv2). These two types of API Gateways in AWS CDK use different integration classes due to differences in their underlying implementations and capabilities.

For HTTP APIs, you should use integrations from the aws-apigatewayv2-integrations module, specifically HttpLambdaIntegration for Lambda functions, which you've already imported at the top of your file. You've correctly set up an HttpLambdaIntegration for your signInLambda, so you need to follow a similar approach for your tokenHandlerLambda.

Here's how you can fix the error:

Replace the LambdaIntegration with HttpLambdaIntegration for your tokenHandlerLambda. You've already imported HttpLambdaIntegration, so you just need to correctly apply it. Here's the corrected portion of your code:

// Correctly create an HttpLambdaIntegration for the tokenHandlerLambda
const tokenHandlerIntegration = new HttpLambdaIntegration('token-handler-integration', tokenHandlerLambda);

// Now, use the correct integration with httpApi.addRoutes
httpApi.addRoutes({
  path: ENDPOINTS.api.TokenHandler,
  methods: [HttpMethod.GET],
  integration: tokenHandlerIntegration,
});

In this corrected code:

• A new HttpLambdaIntegration instance is created specifically for tokenHandlerLambda. The first argument is a unique ID for the integration within the CDK stack, and the second argument is the Lambda function to integrate with.
• This correct integration type is then passed to httpApi.addRoutes, which is compatible with HTTP APIs.

This change will resolve the TypeScript error because HttpLambdaIntegration provides the required properties and methods expected by the addRoutes method for an HTTP API Gateway's route integration.

The error message you're encountering suggests a conflict between different versions or instances of the AWS CDK libraries, specifically between the aws-cdk-lib and the individual @aws-cdk module namespaces. In AWS CDK version 2.x and later, all library modules were consolidated under aws-cdk-lib, and the use of individual @aws-cdk/* packages (e.g., @aws-cdk/aws-lambda, @aws-cdk/aws-iam) is no longer recommended or necessary.

The issue here is that the TypeScript compiler is detecting types for the IRole interface from two different sources, one from aws-cdk-lib (which is the correct and updated source) and another from @aws-cdk/aws-iam (which is likely coming from an incorrect import statement or dependency).

To resolve this issue, ensure the following:

1. Consistent Import Statements: Make sure all your CDK code imports from aws-cdk-lib and not from individual @aws-cdk/* packages. For example, use:

   import { iam } from 'aws-cdk-lib';

   Instead of:

   import * as iam from '@aws-cdk/aws-iam';

2. Review package.json Dependencies: Check your package.json file to ensure that there are no dependencies on individual @aws-cdk/* packages. All CDK functionality should be coming from aws-cdk-lib when using CDK version 2.x and above.

3. Clean and Reinstall Node Modules: After ensuring that all imports and dependencies are correctly pointing to aws-cdk-lib, remove your node_modules directory and the package-lock.json or yarn.lock file, and then run npm install or yarn install again to reinstall your dependencies. This ensures that there are no lingering references to the old packages.

4. Check TypeScript Configuration: Ensure that your tsconfig.json does not have any configurations that might lead to resolving types from older package versions.

After making these changes, try rebuilding your project. This should resolve the type conflict by ensuring that all types are resolved from the unified aws-cdk-lib package, which is the correct approach for AWS CDK version 2.x and later.

I don't understand what you are saying about the imports.

Given the package.json and the import statements you provided, the key issue here is the mixture of AWS CDK v2 (via aws-cdk-lib) with individual @aws-cdk/* packages, which are remnants of AWS CDK v1 and should not be used with AWS CDK v2.

Your current imports mix aws-cdk-lib (the consolidated package for AWS CDK v2) with an individual package import that is not compliant with AWS CDK v2 best practices:

import { HttpLambdaIntegration } from '@aws-cdk/aws-apigatewayv2-integrations';

For AWS CDK v2 (aws-cdk-lib), all AWS service constructs are imported from aws-cdk-lib directly, without needing to reference the individual @aws-cdk/* libraries.

However, for integrations like HttpLambdaIntegration, you would need to use the separate integration library compatible with aws-cdk-lib. The correct import for HttpLambdaIntegration in the context of AWS CDK v2 should come from aws-cdk-lib/aws-apigatewayv2-integrations-alpha or a similar package, but it appears there is a mistake in the use of the package name.

Your package.json explicitly includes an AWS CDK v1 package (@aws-cdk/aws-lambda) which should not be used with AWS CDK v2 (aws-cdk-lib). Here's how you can correct your package.json:

1. Remove the @aws-cdk/aws-lambda dependency.
2. Ensure all AWS CDK functionality is sourced from aws-cdk-lib.

The corrected dependencies section should look like this:

"dependencies": {
  "aws-cdk-lib": "2.147.2",
  "aws-sdk": "^2.1651.0",
  "constructs": "^10.0.0",
  "dotenv": "^16.4.5",
  "source-map-support": "^0.5.21"
}

After cleaning up package.json, your imports should exclusively use aws-cdk-lib for CDK functionality. The problematic integration import needs to be updated or removed depending on whether you find a compatible version for AWS CDK v2.

As of my last knowledge update, aws-cdk-lib/aws-apigatewayv2-integrations-alpha was the correct module for HTTP API integrations with Lambda in AWS CDK v2, but you need to check the latest AWS CDK documentation or package releases for the precise import path as these can change, especially for features that were in alpha or beta.

You might need to install a separate package for the alpha or beta integrations if it's not bundled directly with aws-cdk-lib. In this case, ensure your package.json is updated accordingly, and then adjust your import statement to match the installed package.

After making these corrections:

1. Remove your node_modules directory and package-lock.json or yarn.lock.
2. Run npm install or yarn install to clean install your dependencies.
3. Update your import statements in your TypeScript files according to the corrections described above.

If the HttpLambdaIntegration class is not available directly in aws-cdk-lib, you'll need to look for the correct library or approach for integrating Lambda functions with HTTP APIs in AWS CDK v2, which might involve using a different class or method for the integration.

User at 9:27 am, Jul 1, 2024

I've refreshed the node_modules using the process you described above.

These are my current imports:

import { ENDPOINTS } from '../cdkshared/endpoints';
import {
 aws_cognito as cognito,
 aws_s3 as s3,
 aws_lambda as lambda,
 aws_iam as iam,
} from "aws-cdk-lib";
import { Construct } from 'constructs';
import * as cdk from 'aws-cdk-lib';
import { HttpMethod, HttpApi, CorsHttpMethod } from 'aws-cdk-lib/aws-apigatewayv2';
import { HttpLambdaIntegration } from '@aws-cdk/aws-apigatewayv2-integrations';

Can you tell me what the should be?

Codeium at 9:28 am, Jul 1, 2024

Based on your updated scenario and using AWS CDK v2 (aws-cdk-lib), you will need to adjust the import for HttpLambdaIntegration to align with the AWS CDK v2 libraries. However, as of my last update, aws-cdk-lib does not directly include HTTP API integrations for Lambda in the same way it does for other services. These integrations are provided by a separate library that is compatible with aws-cdk-lib.

Unfortunately, I might not have the most current package names due to the rapidly evolving nature of AWS CDK and its libraries. Previously, integrations for HTTP APIs in AWS CDK v1 were available under @aws-cdk/aws-apigatewayv2-integrations, but for AWS CDK v2, these might have been moved or restructured.

Here's how your imports should look if you're strictly using aws-cdk-lib for AWS CDK v2, with a placeholder for the correct import of HttpLambdaIntegration:

import { ENDPOINTS } from '../cdkshared/endpoints';
import {
  aws_cognito as cognito,
  aws_s3 as s3,
  aws_lambda as lambda,
  aws_iam as iam,
  aws_apigatewayv2 as apigatewayv2,
  aws_apigatewayv2_integrations as apigatewayv2Integrations,
} from "aws-cdk-lib";
import { Construct } from 'constructs';
import { HttpMethod, HttpApi, CorsHttpMethod } from 'aws-cdk-lib/aws-apigatewayv2';

// Assuming the HttpLambdaIntegration is available in a compatible library or module, which might be named like 'aws-apigatewayv2-integrations' or similar
// This is a placeholder and might need adjustment based on the actual library or module name
import { HttpLambdaIntegration } from 'aws-cdk-lib/integrations'; // This path is illustrative and likely incorrect

Given this, you would need to:

1. Verify the correct library or module name for HTTP API integrations with Lambda in the context of AWS CDK v2. This might involve checking the AWS CDK documentation or GitHub repository for the latest information.
2. Install any necessary packages if they are not included in aws-cdk-lib by default. If a separate package is needed, ensure it is compatible with AWS CDK v2 and listed in your package.json.
3. Update the import statement for HttpLambdaIntegration accordingly.

As of my last update, the AWS CDK v2 documentation and package listings would be the best source to confirm the current status and import paths for HTTP API integrations.

User at 9:35 am, Jul 1, 2024

You removed the cdk import.

Now I get Cannot find name 'cdk'.

That seems counter-productive in a CDK module.

Codeium at 9:35 am, Jul 1, 2024

I apologize for the oversight. If you're using cdk as a prefix in your code (e.g., cdk.Stack or other CDK core constructs), you should indeed keep the import for cdk as you had it. Let's reintroduce the correct import statement for cdk along with the adjustments for AWS CDK v2 usage:

import { ENDPOINTS } from '../cdkshared/endpoints';
import {
  aws_cognito as cognito,
  aws_s3 as s3,
  aws_lambda as lambda,
  aws_iam as iam,
  aws_apigatewayv2 as apigatewayv2,
  aws_apigatewayv2_integrations as apigatewayv2Integrations,
  App,
  Stack,
  StackProps,
} from "aws-cdk-lib";
import { Construct } from 'constructs';
import { HttpMethod, HttpApi, CorsHttpMethod } from 'aws-cdk-lib/aws-apigatewayv2';

// Correct import for HttpLambdaIntegration, assuming it's available in the correct library
// Note: As of my last update, you'll need to verify the correct import path for HttpLambdaIntegration in AWS CDK v2
import { HttpLambdaIntegration } from 'aws-cdk-lib/aws-apigatewayv2-integrations-alpha'; // Verify the correct path based on your CDK version and available libraries

export class HandTermCdkStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);
    // Your stack definition...
  }
}

In this corrected version:

• The cdk prefix is not explicitly imported as a separate namespace. Instead, core constructs like Stack and StackProps are imported directly from aws-cdk-lib. This aligns with the best practices for AWS CDK v2, where all constructs and utilities are directly accessible from aws-cdk-lib.
• I reintroduced the App, Stack, and StackProps imports from aws-cdk-lib for defining your CDK stack. This is the correct way to use these core constructs in AWS CDK v2.
• The import for HttpLambdaIntegration is set to 'aws-cdk-lib/aws-apigatewayv2-integrations-alpha', but you should verify this path. The -alpha suffix indicates this might be part of an experimental or alpha release, so the actual import path can vary based on the latest CDK library releases and documentation.

Before proceeding, make sure to check the AWS CDK documentation for the most current information on importing and using HTTP API integrations with Lambda. The CDK API and packages can evolve, and newer releases might introduce changes to how integrations are handled.

User at 9:52 am, Jul 1, 2024

I see now. That looks much better.

I've implemented what you described above and it appears to be passing the linter.

I still have a couple of problems, though.

This section has errors because of the missing cdk

  // Outputs
  new cdk.CfnOutput(this, 'UserPoolId', { value: userPool.userPoolId });
  new cdk.CfnOutput(this, 'UserPoolClientId', { value: userPoolClient.userPoolClientId });
  new cdk.CfnOutput(this, 'IdentityPoolId', { value: identityPool.ref });
  new cdk.CfnOutput(this, 'BucketName', { value: logsBucket.bucketName });
  new cdk.CfnOutput(this, 'ApiEndpoint', { value: httpApi.url || '' });

And, I don't know what to do with the Cognito resource and how to integrate it with the HttpApi.

  // Assuming `api` is your HttpApi object and `userPool` is your Cognito User Pool
  const cognitoAuthorizer = new HttpApi.CognitoUserPoolsAuthorizer(this, 'CognitoAuthorizer', {
   cognitoUserPools: [userPool],
   identitySource: 'method.request.header.Authorization',
   authorizerName: 'CognitoAuthorizer'
  });

That throws the error:

Property 'CognitoUserPoolsAuthorizer' does not exist on type 'typeof HttpApi'.ts(2339)

Codeium at 9:53 am, Jul 1, 2024

Let's address both issues you're facing:

For the outputs section where you're encountering errors due to the missing cdk prefix, since you've already imported aws-cdk-lib, you should directly use CfnOutput without the cdk prefix. However, we did not explicitly include CfnOutput in the corrected imports. Here's how you can adjust the imports and usage:

First, ensure CfnOutput is imported at the top of your file:

import { CfnOutput } from "aws-cdk-lib";

Then, update your outputs section to use CfnOutput directly:

// Outputs
new CfnOutput(this, 'UserPoolId', { value: userPool.userPoolId });
new CfnOutput(this, 'UserPoolClientId', { value: userPoolClient.userPoolClientId });
new CfnOutput(this, 'IdentityPoolId', { value: identityPool.ref });
new CfnOutput(this, 'BucketName', { value: logsBucket.bucketName });
new CfnOutput(this, 'ApiEndpoint', { value: httpApi.url || '' });

The error you're seeing with CognitoUserPoolsAuthorizer is because the way it's being used doesn't match how constructs are defined in AWS CDK v2 (aws-cdk-lib). In AWS CDK v2, you should use HttpUserPoolAuthorizer from the aws-apigatewayv2-authorizers module for HTTP APIs.

Firstly, ensure you have the correct import for HttpUserPoolAuthorizer. Since this might be part of an integration package or has a specific import path in aws-cdk-lib, let's assume a corrected import statement based on the aws-cdk-lib structure:

import { HttpUserPoolAuthorizer } from 'aws-cdk-lib/aws-apigatewayv2-authorizers';

Then, you can define the authorizer and attach it to your routes like so:

// Define the Cognito user pool authorizer for HTTP API
const cognitoAuthorizer = new HttpUserPoolAuthorizer('CognitoAuthorizer', userPool);

// Add routes with the authorizer
httpApi.addRoutes({
  path: '/your-protected-path',
  methods: [HttpMethod.GET],
  integration: yourIntegration,
  authorizer: cognitoAuthorizer,
});

In this setup:

• HttpUserPoolAuthorizer is correctly instantiated with a name and the userPool you've defined.
• When adding routes to httpApi, you can now specify the authorizer in the route options.

Ensure you replace /your-protected-path and yourIntegration with the actual path you're securing and the Lambda integration (or another integration) you're using for that route.

If HttpUserPoolAuthorizer does not import as shown (due to package updates or my outdated information), please refer to the latest AWS CDK documentation for aws-cdk-lib to find the correct import path for HTTP API Cognito authorizers.

Ok, almost everything is passing the linter except in here, the grandRead does not exist on the userPoolClient. I'm not sure how to populate the integration

  // Cognito User Pool

   userPoolName: 'HandTermUserPool',
   selfSignUpEnabled: true,

It looks like there's a misunderstanding in how you're trying to integrate the Cognito user pool client with the HttpLambdaIntegration and the use of userPoolClient.grantRead(userPool).lambdaIntegration. The grantRead method and lambdaIntegration property do not exist on the userPoolClient object in the AWS CDK for a Cognito user pool client. The integration for an HTTP API route should be with a Lambda function, not directly with a Cognito user pool client.

Here's what you typically want to do when integrating a route with a Lambda function and securing it with a Cognito authorizer:

1. Create a Lambda Function: First, ensure you have a Lambda function that you wish to invoke through your HTTP API. This function will handle the requests coming to the path you're securing with Cognito.

2. Set up HttpLambdaIntegration: Next, create an HttpLambdaIntegration instance using your Lambda function. This integration is what you'll use in the integration field when adding routes.

3. Secure the Route with a Cognito Authorizer: Use the HttpUserPoolAuthorizer you've already set up for securing the route.

Here's a corrected snippet based on these steps:

// Example Lambda function for handling requests
const exampleLambdaFunction = new lambda.Function(this, 'ExampleFunction', {
  runtime: lambda.Runtime.NODEJS_14_X,
  handler: 'example.handler',
  code: lambda.Code.fromAsset('path/to/your/lambda/code'),
  // Additional configuration as needed
});

// Create an HttpLambdaIntegration with the Lambda function
const exampleLambdaIntegration = new HttpLambdaIntegration('ExampleLambdaIntegration', exampleLambdaFunction);

// Define the HTTP API
const httpApi = new HttpApi(this, 'HandTermApi', {
  apiName: 'HandTermService',
  description: 'This service serves authentication requests.',
  // CORS configuration if needed
  corsPreflight: {
    allowOrigins: ['*'],
    allowMethods: [CorsHttpMethod.GET, CorsHttpMethod.POST, CorsHttpMethod.OPTIONS],
    allowHeaders: ['Content-Type', 'Authorization'],
  },
});

// Cognito User Pool Authorizer
const cognitoAuthorizer = new HttpUserPoolAuthorizer('CognitoAuthorizer', userPool);

// Secure the route with the Cognito Authorizer
httpApi.addRoutes({
  path: '/api',
  methods: [HttpMethod.GET, HttpMethod.POST],
  integration: exampleLambdaIntegration,
  authorizer: cognitoAuthorizer,
});

Ensure you replace 'path/to/your/lambda/code' with the actual path to your Lambda function code and adjust the runtime and handler as necessary for your Lambda function. This setup defines a Lambda function, integrates it with your HTTP API, and secures the route using the Cognito authorizer.

User at 10:27 am, Jul 1, 2024

Ok, that looks more straightforward and understandable. The CDK project builds, also.

Now I have a question about HttpOnly Cookies.

I currently have this in the signIn.ts

  // Concatenate the Set-Cookie strings into a single header value
  const setCookieHeader = [
   `idToken=${IdToken}; Secure; HttpOnly; Path=/`,
   `accessToken=${AccessToken}; Secure; HttpOnly; Path=/`,
   `refreshToken=${RefreshToken}; Secure; HttpOnly; Path=/`
  ].join(', ');

  return {
   statusCode: 200,
   headers: {
    "Access-Control-Allow-Origin": "*",
    "Access-Control-Allow-Credentials": true,
    "Set-Cookie": setCookieHeader,
   },
   body: JSON.stringify(data.AuthenticationResult),
  };

I want to provide the recommended level of security to prevent XSS by using HttpOnly Cookies, but I don't know how to handle subsequent HTTP requests.

I want to be able to request server content strings stored in S3, and I want to be able to store user-private data into an S3 bucket user folder.

Does the Set-Cookie code look like it complies with the HTTP API?

How do I make a request from the client and have the server know which client I am, so that the server can store and retrieve data from the proper S3 path? (The S3 content will only be accessed through the app and there is no need for direct IAM user access to IAM-restricted bucket paths)

Codeium at 10:28 am, Jul 1, 2024

Your Set-Cookie header setup in the signIn.ts Lambda function looks good for setting HttpOnly cookies, which is a recommended practice to help mitigate the risk of client-side script access (XSS attacks) by not allowing JavaScript access to the cookies. Your use of Secure; HttpOnly; Path=/ with the cookies ensures they are sent over HTTPS and not accessible through JavaScript, which is aligned with security best practices.

The Set-Cookie code complies with HTTP standards for setting cookies, and AWS Lambda@Edge or API Gateway can return these headers to set cookies in the client's browser. However, ensuring compliance with the HTTP API (aws_apigatewayv2.HttpApi in AWS CDK) also involves ensuring that the API's CORS configuration supports credentials. Since you're using "Access-Control-Allow-Credentials": true, you must also specify an explicit domain in the "Access-Control-Allow-Origin" header instead of "*". For example, if your frontend is hosted at https://www.example.com, the Access-Control-Allow-Origin should be set to https://www.example.com.

For subsequent requests from the client, the browser will automatically send the cookies along with each request to the same domain as long as the request type, API endpoint, and conditions meet the criteria defined when setting the cookies (Secure; HttpOnly; Path=/). On the server side (in your Lambda functions), you can then read these cookies from the incoming request headers to identify the user.

To store and retrieve data from S3 based on the user, you would typically:

1. Identify the User: Use the information in the tokens (e.g., idToken or accessToken) to identify the user. You might decode the idToken to extract the user's unique identifier (like sub in JWT) within your Lambda function.

2. Define S3 Bucket and Key Structure: Organize user data in S3 with a clear key structure that includes the user's identifier. For example, user_data/{userId}/file.txt.

3. Lambda Permissions: Ensure your Lambda function has the necessary IAM permissions to read/write from/to the specific paths in the S3 bucket. Use least privilege principles to restrict access only to paths necessary for each function.

4. Server-Side Processing: When a request comes in to retrieve or store user data, the Lambda function should parse the cookies to extract the token, identify the user, and then perform the necessary S3 operations (using the AWS SDK) based on the user's identifier.

Here's a simplified example of how you might extract the token from the cookies in a Lambda function (note that you'll need to parse the Cookie header to get the specific token you're interested in):

exports.handler = async (event) => {
    const cookies = event.headers['Cookie'] || event.headers['cookie'];
    // Parse the cookies to extract needed tokens
    // Example: const idToken = parseCookies(cookies).idToken;
    
    // Identify the user from the token and proceed with S3 operations
    // Example: const userId = decodeToken(idToken).sub;
    
    // Example S3 operation
    // const objectKey = `user_data/${userId}/data.txt`;
    // const s3Response = await s3.getObject({ Bucket: YOUR_BUCKET_NAME, Key: objectKey }).promise();
    
    return {
        statusCode: 200,
        body: JSON.stringify({ message: "Operation Successful" }),
    };
};

This example assumes you have a function parseCookies to parse the Cookie header and a function decodeToken to decode the JWT token. You'll need to implement or use existing libraries for these functionalities according to your specific requirements and programming language.

User at 10:53 am, Jul 1, 2024

That is very good. That's what I wanted to hear.

I have this code now:

import * as AWS from 'aws-sdk';
import { ENDPOINTS } from '../../cdkshared/endpoints';
const cognito = new AWS.CognitoIdentityServiceProvider({ region: 'us-east-1' });

export const handler = async (event: any) => {
  const { username } = JSON.parse(event.body);
  const cookies = event.headers['Cookie'] || event.headers['cookie'];

  try {
    const user = await cognito
      .adminGetUser({
        UserPoolId: 'us-east-1_3q5q5j5q5q',
        Username: username
      })
      .promise();
    // Parse the cookies to extract needed tokens
    const idToken = parseCookies(cookies).idToken;

    // Identify the user from the token and proceed with S3 operations
    const userId = decodeToken(idToken).sub;

    // Example S3 operation
    const objectKey = `user_data/${userId}/data.txt`;
    const s3Response = await s3.getObject({ Bucket: ENDPOINTS.aws.s3.bucketName, Key: objectKey }).promise();
    return { statusCode: 200, body: JSON.stringify(user) };
  } catch (err) {
    return { statusCode: 500, body: JSON.stringify(err) };
  }
}

I am not sure what the best way to import S3 into a CDK Lambda function is.

I want to return "Not profile stored yet" if the data.txt doesn't exist.

I need your help creating the parseCookies and decodeToken functions.

Codeium at 10:53 am, Jul 1, 2024

To address each of your concerns:

You already have the AWS SDK imported, which includes the S3 service. To use S3 in your Lambda function, instantiate it similarly to how you've done with Cognito:

const s3 = new AWS.S3();

Ensure your Lambda function's execution role has the necessary permissions to access the S3 bucket and perform getObject operations.

To handle the scenario where the data.txt file does not exist, you can catch the specific error thrown by the getObject call when the file is not found. AWS SDK for JavaScript throws an error with the code NoSuchKey for this case:

try {
  const s3Response = await s3.getObject({ Bucket: ENDPOINTS.aws.s3.bucketName, Key: objectKey }).promise();
  // If the file is found, return its content
  const fileContent = s3Response.Body.toString('utf-8');
  return { statusCode: 200, body: JSON.stringify({ content: fileContent }) };
} catch (err) {
  if (err.code === 'NoSuchKey') {
    // Return a specific message if the file does not exist
    return { statusCode: 404, body: JSON.stringify({ message: "Not profile stored yet" }) };
  }
  // Handle other errors
  return { statusCode: 500, body: JSON.stringify(err) };
}

You'll need utility functions to parse cookies and decode JWT tokens.

This function takes the Cookie header string, splits it into individual cookies, and returns an object mapping cookie names to values:

function parseCookies(cookieHeader: string) {
  const cookies = {};
  cookieHeader.split(';').forEach(cookie => {
    const [name, value] = cookie.trim().split('=');
    cookies[name] = value;
  });
  return cookies;
}

To decode a JWT token, you can use a library like jsonwebtoken (you'll need to include it in your Lambda's deployment package). The jsonwebtoken library provides a decode method that can parse the JWT without verifying its signature, which might be sufficient for extracting the user ID (sub).

First, install jsonwebtoken in your project:

npm install jsonwebtoken

Then, use it in your Lambda function:

import jwt from 'jsonwebtoken';

function decodeToken(token: string) {
  return jwt.decode(token);
}

Remember, jwt.decode does not validate the token. If you need to validate the token (which is usually the case for security reasons), you'll need to verify the token using jwt.verify and provide the necessary secret or public key, which might be more complex due to the need to manage keys or secrets within your Lambda function.

With these components, your Lambda function should be equipped to handle the retrieval of user-specific files from S3, respond appropriately when files are not found, and parse cookies and JWT tokens to extract user information.

Codeium at 11:15 am, Jul 1, 2024

The error you're seeing indicates that TypeScript is unable to find the type definitions for the jsonwebtoken module. TypeScript relies on these definitions to understand the types and structures of external JavaScript libraries.

To resolve this issue, you should install the type definitions for jsonwebtoken. These definitions are often available in DefinitelyTyped, a repository of high-quality TypeScript type definitions, and can be installed via npm.

Based on the suggestion in the error message, run the following command in your project directory:

npm i --save-dev @types/jsonwebtoken

This command installs the type definitions for jsonwebtoken as a development dependency, which should resolve the TypeScript error. After installing, TypeScript will be able to recognize the types from the jsonwebtoken library, and you should no longer see the error.

Remember, the --save-dev option is used because type definitions are only needed during development and compilation; they aren't required at runtime.

If you run into any more issues or if @types/jsonwebtoken doesn't cover all the usages you need, you might have to manually declare types for any uncovered parts or extend the types in a custom .d.ts file in your project. However, for most use cases, the @types/jsonwebtoken package should suffice.

User at 11:17 am, Jul 1, 2024

I am using Yarn, so I ran yarn add jsonwebtoken --dev. Is that right?

Codeium at 11:17 am, Jul 1, 2024

Yes, using yarn add jsonwebtoken --dev is the correct way to add a development dependency when you're using Yarn as your package manager. This command installs the jsonwebtoken library into your project's node_modules directory and adds it to the devDependencies section of your package.json file.

However, based on the error message you received, you specifically need to install the TypeScript type definitions for jsonwebtoken, not the library itself (which it seems you already have installed). The type definitions are provided by the @types/jsonwebtoken package. To install this using Yarn, you should run:

yarn add @types/jsonwebtoken --dev

This command will add the type definitions for jsonwebtoken to your project, allowing TypeScript to understand the types used by the jsonwebtoken library and resolving the error you encountered.

The error you're encountering now is due to the way TypeScript is trying to import the jsonwebtoken module. By default, jsonwebtoken and many other CommonJS modules do not have a default export, but the syntax you're using (import jwt from 'jsonwebtoken';) is attempting to import it as if it had a default export.

To resolve this, you can change your import statement to use the * as syntax, which is the correct way to import CommonJS modules that export multiple members or do not have a default export:

import * as jwt from 'jsonwebtoken';

This change tells TypeScript to import the entire module namespace (all exported members) under the alias jwt, which is compatible with how the jsonwebtoken module exports its members.

After making this adjustment, your TypeScript compiler should be able to process the import correctly, and you should no longer see the error during the build process.

User at 11:27 am, Jul 1, 2024

There is some dificulty with the decodeToken()

Object is possibly 'null'.ts(2531)
⚠ Error (TS2531)  | 

That is on:

    const userId = decodeToken(idToken).sub;

Codeium at 11:28 am, Jul 1, 2024

The TypeScript error Object is possibly 'null' indicates that the TypeScript compiler has identified a code path where the decodeToken(idToken) call could return null, and thus accessing .sub directly on the result could cause a runtime error if decodeToken indeed returns null.

The jwt.decode function can return null if the token is not valid or cannot be decoded for some reason. To handle this safely in TypeScript, you should add a check to ensure that the result of decodeToken is not null before attempting to access its properties:

const decodedToken = decodeToken(idToken);
if (!decodedToken) {
  // Handle the case where the token cannot be decoded
  return { statusCode: 400, body: JSON.stringify({ error: "Invalid token" }) };
}

// If the token is successfully decoded, proceed with using the decodedToken object
const userId = decodedToken.sub;

This way, you explicitly handle the case where decodeToken returns null, and TypeScript knows that beyond the check, decodedToken cannot be null, thus resolving the type error.

It's also worth noting that jwt.decode() will only decode the payload without verifying the integrity or the signature of the token. In scenarios where you need to verify the token (which is common for authentication and authorization purposes), you should use jwt.verify() instead, and provide the necessary secret or key for verification. Verification would typically be done in an environment where the secret or key is securely stored and not exposed to the client.

Do I need to destroy or delete the old stack first?

I have no need to keep any of it. I can delete the bucket and all the users, if need be.

Codeium at 11:42 am, Jul 1, 2024

The error message you're seeing, Update of resource type is not permitted. The new template modifies resource type of the following resources: [HandTermApi1BECDD2E], indicates that the CloudFormation deployment is attempting to change the type of an existing resource in a way that's not supported by an update operation. Some types of changes to existing resources require the resource to be recreated, which CloudFormation cannot do within a single update operation if it changes the fundamental nature of the resource (like changing its type).

If you're okay with deleting the existing resources and starting fresh, you have a couple of options:

You can manually delete the CloudFormation stack through the AWS Management Console or by using the AWS CLI. This will remove all resources managed by the stack, including the problematic resource, allowing you to redeploy from scratch.

To delete the stack using the AWS CLI, you can run the following command:

aws cloudformation delete-stack --stack-name HandTermCdkStack

Wait for the stack deletion to complete before redeploying your CDK application.

Since you're working with the AWS CDK, you can use CDK commands to manage the stack directly. To destroy the stack and all its resources, you can run:

cdk destroy HandTermCdkStack

This command asks for confirmation before proceeding to delete the stack and its resources. After confirming, it will proceed with the deletion.

Once the stack is successfully deleted, you can redeploy your application:

cdk deploy HandTermCdkStack

This will create a new stack with your resources defined in the CDK application.

If you choose to delete and recreate the stack, make sure to review any resources not managed by CloudFormation or the CDK, such as manually created S3 objects or IAM users, as these might need to be handled separately.

Remember, deleting the stack will remove all resources defined in it, so ensure you have backups or exports of any data you need from services like S3 or DynamoDB before proceeding.

To auto-confirm new users in Amazon Cognito during development, you can use a Pre-Signup Lambda trigger. This trigger allows you to automatically verify email addresses or phone numbers, set custom attributes, and auto-confirm users.

Here's how you can set it up:

1. Create a Lambda function that will be invoked by the Pre-Signup trigger:

   exports.handler = async (event) => {
     event.response.autoConfirmUser = true;
     event.response.autoVerifyEmail = true; // If you want to auto-verify email addresses
     event.response.autoVerifyPhone = true; // If you want to auto-verify phone numbers
     return event;
   };

2. Assign this Lambda function as a Pre-Signup trigger for your user pool. You can do this in the AWS Management Console under the "Triggers" section of your user pool settings, or you can modify your CDK stack to include this trigger if you're managing your Cognito User Pool with CDK. Here's an example of how you might do it with CDK:

   import * as cognito from 'aws-cdk-lib/aws-cognito';
   import * as lambda from 'aws-cdk-lib/aws-lambda';
   
   const preSignupLambda = new lambda.Function(this, 'PreSignupLambda', {
     runtime: lambda.Runtime.NODEJS_14_X,
     handler: 'preSignup.handler',
     code: lambda.Code.fromAsset('path/to/your/lambda/code'),
   });
   
   userPool.addTrigger(cognito.UserPoolOperation.PRE_SIGN_UP, preSignupLambda);

   Replace 'path/to/your/lambda/code' with the actual path to your Lambda function's code.

If your useAuth.http call isn't receiving the cookies in the response, it might be due to the nature of how HTTP clients or tools (like Postman or curl) handle cookies differently from web browsers, especially when it comes to setting HttpOnly cookies.

For testing endpoints that set Http/DOM properties (like cookies), using a browser or a browser-based tool is usually necessary to accurately simulate the end-to-end behavior, including cookie handling.

To test in a browser, you could:

1. Create a simple HTML/JavaScript page that makes the HTTP request to your backend and logs the response. Ensure this page is served over HTTPS if your cookies are set with the Secure attribute.

2. Use browser developer tools to inspect the response headers and the browser's storage to confirm that the cookies are being set correctly.

3. Test your application's flow as it would work in production, by making requests from your frontend application hosted on a web server, observing how it interacts with your backend, and ensuring the cookies are handled as expected.

Remember, when testing in a non-production environment, it's a good idea to use test accounts or data rather than any real user information.
