Install express

npm init -y

npm install --save express

npm install --save-dev @babel/core @babel/node @babel/preset-env

Setup babel ES6 syntax

Create .babelrc file in main backend directory with the following,

{ "presets": ["@babel/preset-env"] }

this gives us modern ES6 syntax using server.js

npx babel-node src/server.js

npm install --save body-parser

npm install --save-dev nodemon

for hot-encoding/refreshing

npx nodemon --exec npx babel-node src/server.js

MongoDB Setup

mkdir -p /data/db

mongod

npm install --save mongodb
