Graphql Fullstack Microservice Application With OAuth2

Graphql

GraphQL is a query language and server-side runtime for application programming interfaces (APIs) that prioritizes giving clients exactly the data they request and no more. GraphQL is designed to make APIs fast, flexible, and developer-friendly. It can even be deployed within an integrated development environment (IDE) known as GraphiQL. As an alternative to REST, GraphQL lets developers construct requests that pull data from multiple data sources in a single API call.

OAuth2 Authorization Server

We are using oauth2 authorization server to secure the application.

To log in to your app, you'll need to have Spring OAuth2 Authorization Server up and running.

The OAuth2 Authorization Server can be accessed from this link via kubernetes.
http://auth.susimsek.github.io

The OAuth2 Authorization Server can be accessed from this link via heroku.
https://graphql-fullstack-auth-service.herokuapp.com

The default user credentials information is as follows. You can log in to the authorization server using that credential information or login to the authorization server with gmail.

username: admin
password: password

Application

Development

Before you can build this project, you must install and configure the following dependencies on your machine.

Prerequisites for Backend

• Java 17
• Kotlin
• Maven 3.x
• Mongodb
• Nodejs 14+ (required for Apollo Gateway)

Run the microservice

You can install the dependencies by typing the following command

mvn clean install

You can run the spring boot microservice by typing the following command

mvn spring-boot:run

Run the apollo gateway

You can install the dependencies by typing the following command

npm install

You can run the apollo gateway(accessible on http://127.0.0.1:4000) by typing the following command

npm run start:dev

Prerequisites for Frontend

• Nodejs 14+

Run the app

You can install the dependencies by typing the following command

npm install

You can run the react app(accessible on http://127.0.0.1:3000) by typing the following command

npm start

Supergraph Composition

Prerequisites

• Rover

You can federate multiple subgraphs into a supergraph by typing the following command

rover supergraph compose --config ./deploy/supergraph.yaml > ./deploy/supergraph.graphql

Sonar

Code Quality For Backend

You can test code quality locally via sonarqube by typing the following command

mvn -Psonar compile initialize sonar:sonar

Code Quality For Apollo Gateway

You can test code quality locally via sonarqube by typing the following command

npm run sonar

Code Quality For Frontend

You can test code quality locally via sonarqube by typing the following command

npm run sonar

Detekt

Detekt a static code analysis tool for the Kotlin programming language

You can run detekt by typing the following command

mvn antrun:run@detekt

Caching

Redis is an Open Source, in-memory data structure store that can be used as a performant caching solution Depending on your configuration, you can choose to use Redis as a single server node or as a distributed cache

Default cache expire time is 1 hour but you can change it via vault by changing the following environment variable

CACHE_EXPIRATION=3600s

Docker

You can also fully dockerize your application and all the services that it depends on. To achieve this, first build a docker image of your app.

Build Docker Image for Backend

The docker image of microservice can be built as follows:

mvn -Pjib verify jib:dockerBuild

Build Docker Image for Frontend

The docker image of ui can be built as follows:

docker build -t web .
