cognito2apig

AWS API Gateway Test with cognito

Notes

The original owner holds several PRs for a while. So I have to manage the change with new npm packages.

A simple CLI to test API Gateway endpoints with IAM authorization. Uses the AWS SDK, AWS Cognito JS SDK, and the generic [API Gateway Client][apiGClient]. Using the login information given, this tool logs a user into the Cognito User Pool, gets the temporary IAM credentials, and makes the API request. It can be difficult to do these steps by hand without scripting them.

Installation

To install globally run the following:

$ npm install -g cognito2apig

You can also use it locally using:

$ npx cognito2apig

Usage

If you have it globally installed:

$ coginto2apig \
  --username='johndoe' \
  --password='password' \
  --user-pool-id='us-east-1_Xxxxxxxx' \
  --app-client-id='29xxyyxxyxxxyyxxxyy' \
  --cognito-region='us-east-1' \
