An Express application that uses promises instead of callbacks

This is a simple project to help me better understand promises and how use NodeJS with MySQL

The premise is simple

HTTP Request -> index -> route -> controller -> service -> model

So, all HTTP requests come to the index file. Routing is handled by Express, which then creates the Controller and all its dependencies.

The controller then calls a service, which looks at the request and makes decisions on whether to process an update, delete, insert, or select on the database.

ESLINT TO FIX FILES

I've decided to use ESLint to help each file feel and look more consistent. There is a file: .eslintrc.json that contains all the rules

When you create a new file (or edit an existing file), be sure to run the following command. ESLint will automatically analyze the code and fix it to adhere to the standards

node_modules/eslint/bin/eslint.js --fix dir/file.js

Services

Services are where you application logic lives

Methods on each class do 1 thing

Methods on a service class call those methods.

Services are "smart". Everything else is dumb

Scripts to help with Development

I program on a Mac, but use Ubuntu for the MariaDB server

In order to connect to the VM these are the steps

• (from vm) ssh -R 2202:localhost:22 kearney@mac_ip_address
• (from mac) ssh -p 2202 kearney@localhost
• (from vm) ssh -R 3366:localhost:3306 kearney@mac_ip_address
• (on vm) ssh-keygen -t rsa then copy the id_rsa.pub file to the mac under .ssh/authorized_keys and take the id_rsa.pub from mac and put on vm in .ssh/authorized_keys
