Description

Microservice boilerplate based on NestJS v10, built with TypeScript.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. This project cover both, running on a containerized environment using Docker, or on your local machine.

Guidelines

Setup

Docker Environment

This section will cover the steps to follow for a containerized version of this project.

Prerequisites

• A Docker engine running on your local machine. Reffer to official documentation for intructions.
• Post-installation steps for Linux. Reffer to official documentation for intructions.

Installation

(cd scripts/ && sh build.sh)

The build script Will:

• Create private network for containers.
• Configure and deploy MYSQL container.
• Configure and deploy Adminer container.
• Configure and deploy EventStore container.
• Configure and deploy nestjs-boilerplate container.
• Connect containers to private network.
• Enables hot-reloading by mounting working directories inside nestjs-boilerplate container.
• Create and mount data directory to mysql container for persistence under $HOME/mysql-data-dir.
• Create and mount data directory to EventStore container for persistence under $HOME/eventstore-data-dir.

Usage

• To access the App home page navigate to http://localhost:3000 [DEFAULT PORT].
• To access the EventStore Admin UI navigate to http://localhost:2113 [DEFAULT PORT].
• To access the Adminer UI navigate to http://localhost:8080 [DEFAULT PORT].
• To change default setting, edit script/dev/evVAr.sh

Access

• EventStore:

  • credentials:

    User	Password
    admin	changeit

• Adminer

  • Form

    Server	User	Password	Database
    sql-db	root	root	demo-db

• Microservice Docker Container

      sudo docker exec -it devtest bash

Clean up

Soft clean up

(cd scripts/ && sudo sh cleanup.sh)

The cleanup script soft Will:

• Remove private network.
• Stop and remove MYSQL container.
• Stop and remove Adminer container.
• Stop and remove EventStore container.

Hard clean up

#both commands are equivalent
#option1 
(cd scripts/ && sudo sh cleanup.sh -h)
#option2
(cd scripts/ && sudo sh cleanup.sh --hard)

The cleanup script hard Will:

• Remove private network.
• Stop and remove MYSQL container.
• Stop and remove Adminer container.
• Stop and remove EventStore container.
• Delete Mysql data directory.
• Delete EventStore data directory.

local Environment

This section will cover the steps to follow for a local version of this project.

Prerequisites

• A running EventStore. Reffer to official documentation for intructions.
• A running Mysql Server. Reffer to official documentation for intructions.
• A running Node Server. Reffer to official documentation for intructions.
• npm

PS: in order to start receiving events from the EventStore, you should enable projections. (disabled by default)

Installation

$ npm install

Database setup

• using TypeORM CLI. Reffer to migration documentation for intructions.
