develop:
This repository is an iCSD Capgemini initiative that hosts an application reference called My Thai Star. This application is about the management of a restaurant.
This project is intended to be an example for the usage of new technologies in web development. Here is a list of all technologies involved:
-
Angular
Client-side developed using the latest version of this framework: Angular 6.
-
Java
Server-side developed using the 3.0 version of devon4j.
-
Node
Server-side developed using the basics of the NestJS framework. A node.js framework built on top of Express.js based on TypeScript language. This server-side backend is based on the devon4node incubator.
-
.NET
Server-side developed using the dotnet framework.
-
Swagger
Used this technology to define contracts between client-side(s) and server-side(s). So necessary when every back-end of the project (.NET, NodeJS and Java) is prepared to match with the Angular client exactly in the same way, being transparent to the user.
-
Production Line
Tool used for Continuous Integration and Continuous Delivery. Inside of this Jenkins and SonarQube are used. Also used Docker for the deployment in an external server.
-
Mr Checker
MrChecker is a testing framework included in devonfw with several useful modules, from which we will focus on the Selenium Module, a module designed to make end-to-end testing easier to implement. More about it here.
This application can be easily deployed using Docker and docker-compose.
$ docker-compose up
As both Angular and Java Dockerfile(s) are using multi-stage build, apps are being built in their development environments (node for Angular and maven for Java) and then deployed in nginx and tomcat respectively.
3 Docker containers will be created:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

fdb63e26d299 mythaistar_angular "nginx -g 'daemon of…" 3 minutes ago Up 3 minutes 80/tcp, 443/tcp mts_angularThe usage of the reverse-proxy only uses 1 port of the Docker host (where this is deployed), the 8080. All internal communication of containers is done using docker alias of services.
If we are using a CICD pipeline and we store the artifact on nexus, we can also deploy it without recompile all code. For this purpose there are three deployment pipelines:
-
deployment: deploy all application with a reserve-proxy
-
java: deploy only the java application
-
angular: deploy angular application + reverse-proxy (you must run the java deployment at least once before running this deployment)
The result of this deployment will be the same as in the deployment from code, but instead of compiling the artifact again downloads it from nexus. All resources (docker-compose.yml, Dockerfiles and nginx.conf) are stored in the reverse-proxy folder.
