This project was created to show the usages of the following soa patterns:
- Authentication broker
- Service Facade
- Adapter
The purpose of this application is to allow users the ability to search books by ISBN from sources (public API’s) from all over the world. The system contains 3 main components:
- Authentication API that acts as a authentication broker (NodeJS)
- Books API (NodeJs)
- Web portal (Angular v7)
Below is the system architecture:
-
Authentication Broker An authentication broker assumes responsibility for authenticating consumers. Consumers are issued a token they can use to access services.
-
Service Façade A service façade sits between a service and a contract. It eliminates the tight coupling between the service and its contract. This is intended to minimize changes to the service if the contract changes. A service can have multiple service façades to support multiple contracts.
-
Message Translator The Message Translator is the messaging equivalent of the Adapter pattern. An adapter converts the interface of a component into a another interface so it can be used in a different context.
-
In order to run the api's you need to run the following docker compose command:
docker-compose up -
In order to run the web portal you need to run the following command:
ng serveor with --prod to use the production environment and bundle.
If you want to run docker for each individual api you can use the following:
$ docker build -t soa/authentication.api .
$ docker run -p 3000:3000 -d soa/authentication.api$ docker build -t soa/books.api .
$ docker run -p 3001:3001 -d soa/books.api
