Node-TS API Template.

Purpose.

• A simple Typescript API written in Node that can be used as a starter in multiple API application usecase scenarios. We will be using:

1. Express - For API SetUp
2. TypeORM - For our PostgreSQL ORM interfacing with our app.
3. Docker Compose - To spin up our PostgreSQL and pgAdmin4 containers.

SetUp.

npm init

npm i -S express
npm install -D typescript @types/express

tsc --init

• Setup package.json with your start scripts in dev env.

npm install -D ts-node-dev

* Dev environment running and watching script.
"dev": "node_modules/.bin/ts-node-dev --respawn --notify false --prefer-ts --ignore-watch node_modules -- src/app.ts "

• SetUp TypeOrm.

npm install -S typeorm reflect-metadata pg

npm install -D @types/node

** ormconfig.json

• This file contains metadata information needed by TypeORM before running the application. It contains database configuration information, and credentials, logging, entity and migration information.

Running the application.

• Before running the app, ensure the containers are up and running, in order for you to create the node_sample DB over pgAdmin4 interface.

docker-compose up

• In order to login to the pgAdmin4 console, use the credentials provided in the docker-compose pgadmin container environment configs, to login and check your IP Address(on Linux using ip a), before proceeding as you will use this as a HostName to create a connection between pgAdmin4 container and PostgreSQL Container.

• After creating node_sample database or the database name in the ormconfig.json, start your application by running:

npm run dev
