by John Vincent

Posted on August 27, 2020

Gomoku is a responsive, Progressive Web application version of the popular Gomoku game built using React.

Gomoku, also called Five in a Row, is an abstract strategy board game. Players alternate turns to place a stone of their color on an empty square. The winner is the first player to form an unbroken chain of five stones horizontally, vertically, or diagonally.

Technical

Gomoku is a Progressive Web App (PWA)
Gomoku is built using React, Redux, HTML5, Sass and CSS3, the server-side using

Spring Boot Microservice and Java as the services server.

Gomoku is fully responsive, adapting for mobile, table and desktop viewports.
Gomoku resources are served from Nginx Server
Gomoku is fully unit tested on the front and server-side. For React testing, Jest has been used.
Gomoku is deployed to an Ubuntu droplet at Digital Ocean and kept running using PM2
All client and server communications are performed using https.

Deploy

Test

Production Status

To show the state of the microservice

Notice the logs may be found at

To monitor the microservice

Development

Gomoku Client is a browser based client.

Gomoku Server is a Spring Boot Microservice that provides the AI (artificial intelligence).

Build Spring Boot Microservice

Spring Initializr

Dependency: Spring Web

Start eclipse-jee from /Users/jv/Desktop/MyDevelopment/github/website/gomoku-server

Import Project from /Users/jv/Desktop/MyDevelopment/github/website/gomoku-server

Server Port

Edit application.properties and add server.port=9415

Execute the service

Create /Users/jv/Desktop/MyDevelopment/github/website/gomoku/gomoku-server/gomoku-server/execute

echo " "
echo "Run the Spring Boot server"
echo " "
#
./mvnw spring-boot:run

Execute the service

cd /Users/jv/Desktop/MyDevelopment/github/website/gomoku/gomoku-server/gomoku-server

./execute

Test the service

http://localhost:9415/gomoku/rest/move/scores

Build Microservice as an executable Jar

Create /Users/jv/Desktop/MyDevelopment/github/website/gomoku/gomoku-server/gomoku-server/create-package

#!/bin/sh
#
# script to create Jar
#
#
echo "Maven clean and make the package"
./mvnw clean package

echo "Save Jar"
cp target/gomoku-server-0.0.1-SNAPSHOT.jar ../gomoku-server.jar

echo "Completed"

Run the script create-package

and

java -jar gomoku-server.jar

Test using

http://localhost:9415/gomoku/rest/move/scores

Other

The proxy of the /gomoku/rest to a microservice http://localhost:9415/gomoku/rest will cause CORS problems.

Spring Boot has a built-in solution.

	@CrossOrigin(origins = "*", allowedHeaders = "*")
	@GetMapping("/gomoku/rest/....")
	public List<Solution> findSolution(@RequestParam(value = "id", defaultValue = "0") int id) {
		StringBuffer sb = getFileContents(id);
		List<Solution> list = Utils.JSONArraytoListObject(sb.toString());
		return list;
	}

This implementation allows all. To be more restrictive, use something like

@CrossOrigin(origins = "http://localhost:9432")

or for multiple origins

@CrossOrigin(origins = {"http://localhost:9432", "https://www.gomoku.johnvincent.io"}, allowedHeaders = "*")
