  Just created a package.json

  npm install --save express pg knex body-parser hbs

  Bunch of stuff installs

  You just installed Express, Postgresql, knex, body-parser, and handlebars


  in the main directory
  touch app.js .gitignore .env

create the following directories
bin
db
public
routes
views

with the following commands

mkdir bin
mkdir db
mkdir public
mkdir routes
mkdir views

in db create knex.js
in views create all.hbs error.hbs index.hbs layout.hbs new.hbs
in routes create index.js users.js
in public mkdir images javascripts stylesheets

knex init

  This will create a knexfile.js for your database configuration.

Change your entire knexfile.js to read

module.exports = {

  development: {
    client: 'postgresql',
    connection: 'postgres://localhost/DATABASE_NAME',
  },

  production: {
    client: 'postgresql',
    connection: process.env.DATABASE_URL
},
};

change DATABASE_NAME to whatever you named your database


Change your app.js file to read the following:

  var express = require('express');
  var app = express();

  app.get('/', function (req, res) {
    res.send('it worked');
  });

  app.listen(3000, function () {
    console.log('This shit is working yo');
  });



You will ultimately need to add more configuration and middleware in this file but this is enough to start you out.


now we'll create the database
createdb testdatabase

knex migrate:make testdatabase

Just created a migrations folder with a migrations file in the folder

Now make seed folder by running
seeds folder was just made with data


Your express app should be up and running to use commands
nodemon

in the terminal

point your browser to http://localhost:3000/

it worked should show up in your browser Now

There is WAYYYYYY more configuration and setup to get done but at least you'll get to see it working in its most basic form.
At this point you still have 1,000 more steps.****DISCLAIMER I almost make no claim that this is the best or even a 
good way to do it. I just put this together as a way to practice.

For further practice it might help to create a folder called expresspractice
then within that folder do mkdir practice1 practice2 practice3 practice4 practice5
That will make 5 folders where you can build and burn 5 times to pickup the pace in setting it up.
