** e-commerce sample application using powered by Spring, Angular 4, MongoDB, Redis and more._**

This sample e-commerce application demonstrates how to build an application using microservices architecture paradigm with Polyglot Languages (Java, JavaScript) & Polyglot Persistance software (MongoDB, Redis). This sample application includes following functional microservices & infrastructure microservices. All of these microservices are independently deployable applications and are organized around business capabilities.

###Functional Microservices

• Product Catalog Microservice
• Cart Microservice

The application is setup as multi-level gradle project where each microservice is arranged as a sub-module under single parent project. It enables to run each microservice individually.

##Prerequisites

• MongoDB - Install MongoDB from(running on default port), https://www.mongodb.org/downloads
• Redis - Install Redis from(running on default port), https://redis.io/download
• JDK 8 - Install JDK 1.8 version from, http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
• Gradle [Optional] - Download latest version of Gradle from https://gradle.org/gradle-download/ (binary distribution is good enough) and configure your machine with Gradle as specified at, https://docs.gradle.org/current/userguide/installation.html
• Node.js - Install Node.js from, https://nodejs.org/en/download/
• Angular 4 - Install Angular 4 from, http://cli.angular.io

##Installation

Clone respository source code by executing following instruction to any folder on your machine,

git clone https://github.com/damit619/e-commerce-app.git
cd e-commerce-app

###Building Application

Gradle has been used as a build tool to build Spring Boot based Microservices applications. Issue following command on your terminal/console window,

gradlew clean build

cd product-catalog-service
gradlew bootRun

cd cart-service
gradlew bootRun

This command might take a while for first time as it needs to download serveral dependency libraries from Maven repository. This command will build & package all microservice applications.

Frontend application is a Single Page Appliction built using Angular 4. The source code of this application is available under, 'ecomm-webapp' folder. Issue following commands in sequence to build & run frontend app,

cd ecomm-webapp
npm install
ng serve

Note: 'npm install' command may take a while, as it needs to download all dependent npm modules used by frontend app.

Once above instructions successfully executed, you can view e-commerce application by browsing below URL, http://localhost:4200
