felix19350 / Searchable.groovy
Created July 14, 2014 22:52
Seachable.groovy bulk index config
/**
* Should the database be indexed at startup (using Compass:GPS)?
*
* Possible values: true|false|"fork"
*
* The value may be a boolean true|false or a string "fork", which means true,
* and fork a thread for it
*
* If you use BootStrap.groovy to insert your data then you should use "true",
* which means do a non-forking, otherwise "fork" is recommended

Last active January 14, 2021 22:53
Notes on cognito JWT token validation
/***
* AWS Cognito signs the tokens using the RS256 algorithm. Contrary to most common examples (using HMAC + SHA256) that use
* a shared secret, the RS256 uses assymetric crytography, so in order to validate the JWT we need to obtain the public key
* that matches the private key used to generate the token signature.
* Therefore, the critical step is to download the public key from the discovery endpoint.
* Cognito makes this available as a JWKS, JSON Web Key Set, available at a well known location of your user pool
* e.g. https://cognito-idp.{region}.amazonaws.com/{user-pool-id}/.well-known/jwks.json
* Furthermore, the issuer of the token is the user pool (the iss clamin is the user pool URL) and the audience is the
* particular client that was configured on the user pool (the aud claim is set to a specific client id of that pool).
* See: https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-settings-client-apps.html

Gradle notes

Test dependencies in multi-module projects

Scenario:

Gradle multi-module project that is comprised of two modules A, B and C. Module A exposes functionality (e.g. json serialization configurations) that is consumed by module B and C. Module A also has a set of test helpers (in src/test/) that are useful so that modules B and C are not concerned with bootstrapping the serialization part on their unit tests.
