const Layer = require('express/lib/router/layer');
Layer.prototype.handle_request = async function handle(req, res, next) {

Notes on using Cognito with Serverless

  • event.requestContext.identity.cognitoIdentityId should be the user id
  • Cognito User Pools are for handling user registration, authentication, and account recovery
  • Cognito Identity Pools (or Cognito Federated Identities) are a way to authorize users to directly use the various AWS services in your account, such as S3, DynamoDB, and, most relevant for APIs, API Gateway
