Integralist

The three design patterns (Adapter, Facade and Bridge) all produce the result of a clean public API. The difference between the patterns are usually due to a subtle context shift (and in some cases, a behavioural requirement).

Adapter

The primary function of an Adapter is to produce a unified interface for a number of underlying and unrelated objects.

You will notice this pattern being utilised in many applications. For example, ActiveRecord (the popular Ruby ORM; object-relational mapping) creates a unified interface as part of its API but the code underneath the interface is able to communicate with many different types of databases. Allowing the consumer of the API to not have to worry about specific database implementation details.

The principle structure of this pattern is:

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

if [[ -z ${CONTEXT} ]]; then
  echo "Usage: $0 KUBE-CONTEXT"
  exit 1

Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

To learn more about migrations, check out this article on the different types of database migrations!

OAuth 2.0 Token Introspection with NGINX and njs

This configuration enables NGINX to validate an authentication token against an authorization server by using OAuth 2.0 Token Introspection (RFC 7662). This solution uses the auth_request module and the NGINX JavaScript module to require authentication and perform the token introspection request.

By default, the client's authentication token is expected as a bearer token supplied in the Authorization header. If supplied elsewhere in the HTTP request, the $access_token variable must be configured to specify where to obtain the token.

Token introspection requests are authenticated. By default, the $oauth_client_id and $oauth_client_secret variables are used to perform HTTP Basic authentication with the Authorization Server. If only the $oauth_client_secret variable is specified then that value is used
