There are a lot of section that goes into creating a production grade NodeJS application. In this repository I tried to gather as much as possible. This is an ExpressJS application with the following features.

• Typescript all the way
• EsLint, Prettier and Husky integration
• Docker
• Sequelize integration
• Multiple Environments
• Logging
• Error handling in a central place
• Request Validation
• Swagger API documentation
• Dependency Injection
• Setting up Testing

Let me know what else can make this repo even better

One key difference with other similar projects is that I documented every step in the way. Following is a series of articles that will guide you on how to build this project from absolute scratch.

• Creating NodeJS with Typescript from Scratch
• Adding Eslint, Prettier and Husky
• Introduce Express into the Project
• Adding Docker for Development and Production
• Setting up local database with Docker
• Error Handling
• Request Validation
• Production Grade Logging
• Environment Configuration
• Security Best Practices
• Dependency Injection
• Using Sequelize ORM
• Adding Swagger for API Documentation

The major technologies that were used to build this project are:

• NodeJS
• Typescript
• Sequelize
• Docker

Here goes the instructions to get the project up and running.

To run this project You will need the following things installed on your machine

• NodeJS
• NPM
• Docker (Optional)

It's super simple. If you already have Docker installed and running on your machine you can just run

docker-compose up

It will give you 3 things

1. The Express server in development mode (With hot reloading support)
2. A PostgreSQL database server (If you prefer something else like MySQL just make a couple of change inside the docker-compose.yaml file) The credentials are

DB_HOST = database-layer;
DB_NAME = dbname;
DB_USER = dbuser;
DB_PASSWORD = dbpassword;

3. A Database investigation tool named Adminer (You can inspect any kind of database from the browser) You can access it from http:https://localhost:8080

If you want to change or update any code you can just make the change and from the console you will see that the server is getting updated.

If you don't use Docker then you will get an exception specifying you don't have any database. TO avoid that you can do 2 things.

1. First go inside the .env.development file and specify the following variables of a database server that you are using.

DB_HOST=database-layer
DB_NAME=dbname
DB_USER=dbuser
DB_PASSWORD=dbpassword

2. Otherwise go inside the index.ts file and on line number 29 comment of the following line

dbClient = await connection.sync();

If you want to add a new route then you will goto /routes folder and add a new Router. Then register that router in the index.ts file under the /routes folder.

Then you will create a Controller under the /controllers directory.All business logics should go into there.

Specific use cases should be handles by Service classes under the /service folder.

All Database related things should go under /repositories folder.

To create a new model for data base look into the /models folder.
