Description

This is а simple show-case where we have exposed simple REST API but at some point stakeholders wants a data grid with pagination (displaying minor subset of properties). GraphQL makes it super easy to implement this requirement with a lot of flexibility so API consumers can pick which fields want to be served as long as they are supported and defined in the GraphQL schema.

Setup

• JDK 21 as baseline
• Maven
• MongoDB v4.4 (https://www.mongodb.com/try/download/community)
• Postman as nice to have (https://www.postman.com/)
• Robo 3T (Robomongo) as nice to have (https://robomongo.org/download) or MongoDB Compass (https://www.mongodb.com/products/compass)
• Docker

Running Local

To Build:

mvn clean verify

To Run:

mvn spring-boot:run

• Navigate to http://localhost:8080/swagger-ui.html to check Swagger UI API definition.
• Setting up demo.initial.data.load to true in application.properties will load some sample dummy data on startup.
• Import postman collection in case you want to check up GraphQL exposed end point.

To spin up MongoDB and Mongo-Express via docker compose:

docker compose -f .\docker-infra.yml up -d 

To shut it down:

docker compose -f .\docker-infra.yml down

To format the code base:

mvn com.spotify.fmt:fmt-maven-plugin:format

Data Volumes are available under: /dockervolume

Happy coding!!!
