Build Auth & Sessions into our Fruits App Part 1

Lesson Objectives​

  • add sessions and auth on top of our fruits build

Set up​

  • cd into the starter code, make sure you are on the same level as package.json
  • npm install to install dependencies (express, ejs, method-override, mongoose)

Set up environmental variables​

We need a way to protect our sensitive information and a way to store environmental variables that are specific to our computer (in contrast to a co-workers computer or the environment in a cloud service).

In our class repo, at the route we have a .gitignore file. This file tells git which files to never track. In there it states to never track node_modules nor .env - that way our values stay safely on our machines.

  • in .env let's set up the environmental variables for your port and mongo connection string

  • touch .env

  • npm install dotenv

in .env

.env
PORT=3000
MONGODB_URI=mongodb://localhost:27017/fruits_auth

IMPORTANT this is NOT a JavaScript file.

  • No spaces!

  • No semi-colons!

  • No quotes!

  • In server.js - under configuration

  • require('dotenv').config()

The variables will be accessed by process.env

server.js
const PORT = process.env.PORT
const mongodbURI = process.env.MONGODB_URI

We should now be able to run nodemon

Nodemon

  • Go to /fruits/setup/seed to seed some data
  • Make a fruit
  • Update a fruit
  • Delete a fruit
