Lambda Function Interaction

In your serverless application, Lambda functions play a crucial role in handling authentication, data retrieval, and processing. Here's a breakdown of how these functions interact with each other:

getTokenFromCloudflare​

  • Purpose: Receives the initial Cloudflare token when a user lands on your website.
  • Role: Validates and processes the token, ensuring its authenticity.
  • Integration: Triggered when a user first lands on your site.

getUserInfoFromLinkedIn​

  • Purpose: Fetches user information from LinkedIn.
  • Role: Makes authenticated API requests to LinkedIn's API and retrieves user data.
  • Integration: Can be called directly by your React app or as part of a chain of Lambda functions.

processLinkedInData​

  • Purpose: Processes the data retrieved from LinkedIn.
  • Role: Formats and prepares LinkedIn user data for use in your application.
  • Integration: Part of the Lambda function chain, after getUserInfoFromLinkedIn.

createCognitoSession​

  • Purpose: Manages user sessions and authentication in Amazon Cognito.
  • Role: Creates and manages sessions for authenticated users.
  • Integration: Called after successful validation and data processing.

getDataFromLinkedInAndCognito​

  • Purpose: Coordinates the flow by invoking getUserInfoFromLinkedIn, processLinkedInData, and createCognitoSession.
  • Role: Orchestrates the logic for data retrieval, processing, and session creation.
  • Integration: Called from your React app or as needed.

These Lambda functions work together to ensure a seamless user experience on your website. They handle authentication, data retrieval, processing, and session management, ensuring that users can access LinkedIn data securely and efficiently.
