It allows to submit email addresses as sales leads. The user is also allowed to sign up if there are no users in the database the first one will get admin privileges and will be able to manipulate the sales leads from the menu.

Technologies used:

Node.js, Express.js, PostregSQL Templating engine for the frontend used: PUG, Bootstrap

How to use.

Clone the repository and use the set of commands below to set your environment up:

To install node.js version 10.16.3 use below

nvm install 10.16.3

To switch to a different version of node installed

nvm use 12.1.0

Install ExpressJS express generator -g stands for global

npm install express-generator -g

To generate an express project --view=pug - use the pug templating engine myapp is the projects name

express --view=pug myapp

install dependencies

cd APPNAME npm install

run the app

DEBUG=myapp:* npm start

or use startnode.sh APPNAME script that I have created

Install nodemon and then edit package.json start script.

npm install nodemon --save-dev

by replacing the scripts part of file with this:

  "scripts": {
    "start": "if [[ $NODE_ENV == 'production' ]]; then node ./bin/www; else nodemon ./bin/www; fi"
  },

It's good to create a folder called controllers to controll routes better in routes for example use to get index.js:

let index = require('../controllers/index')

router.get('/', index.getIndex)

Add a .gitignore file and include the node_modules in it:

node_modules

Install postgresql

brew install postgresql

Start postgresql once (remember that you need to restart it once you restart your computer or just use the start script: 'startnode_and_db.sh')

pg_ctl -D /usr/local/var/postgres start

Get into postgress to setup database:

psql postgres

Create user to delete use DROP instead of CREATE

CREATE ROLE "express-mvp-dbuser" WITH LOGIN PASSWORD '123.456';

Creater a database:

CREATE DATABASE "express-mvp-db";

Install sequelize

npm install sequelize npm install sequelize --save

Install PG

npm install pg --save

Install sequelize-cli

npm install sequelize-cli -g

In the root app folder create a .sequelizerc file

touch .sequelizerc

add the content to .sequelizerc :

const path = require('path');

module.exports = {
  'config': path.resolve('config', 'database.json'),
  'models-path': path.resolve('', 'models'),
  'seeders-path': path.resolve('', 'seeders'),
  'migrations-path': path.resolve('', 'migrations')
}

Initialize sequelize

sequelize init

In the config/package.json file edit the database details and add "module.exports = " at the very begining actually the module.exports causes error

const path = require('path'); EXAMPLE

module.exports = {
  'config': path.resolve('config', 'database.json'),
  'models-path': path.resolve('', 'models'),
  'seeders-path': path.resolve('', 'seeders'),
  'migrations-path': path.resolve('', 'migrations')
}

Once created a DB model and a migration file it is needed to initialize the migration We normally create migration files with todays date and time and the migration name for example:

201911250916-AddIsAdminFieldToUsers.js

Then use command below to perform the migration:

sequelize db:migrate

Install passport.js for authentication www.passportjs.org

npm install passport passport-local bcrypt validator express-session connect-flash --save

Install lodash and validator

npm install lodash validator --save
