On this occasion, I'm going to try to explain how to create a simple Rest API using Express framework, PostgreSQL, and coding with TypeScript.
Please make sure that Node.js (>= 10.13.0) is installed on your operating system and docker.
You can follow the tutorial at Create a Rest API with Express, PostgreSQL, TypeOrm, and TypeScript.
git clone https://github.com/bautistaj/expressApi
cd expressApi
npm run install
npm run tsc
node ./build/server.js
