Understand BCrypt Hashes

1

Okay,I did var bcrypt = require('bcrypt')
In the server.js
Then,I added BCrypt into Dependencies part
like this:
"dependencies": { "express": "^4.16.3", "bcrypt": "^3.0.1" },
So,WHAT is the problem???
(Note: And yes,I did on the link FreeCode camp has given [Glitch].)

2

did you install BCrypt?

You have to do npm i BCrypt --save in your terminal to have the package

3

How do I do that?
Can you tell me how can I do it?
Do I install it by “Add Package” button?

4

what error are you getting?

5

It says “error error”

6

how did you get the version of the BCrypt?

7

Like I added it on dependencies part in package.json and I required it in server.

8

To add a package

cd into the directory of your project

npm install package --save(optional)

9

So the code is…npm install packagae-- save(optional)??

10

Do I add it on server.js?

11

change the var to const

run npm install

12

did FCC give you the version of BCrypt to add?

13

No,which version should it be?
Code:

// server.js
// where your node app starts

// init project
const bcrypt = require('bcrypt')
const express = require('express')
const app = express()

// we've started you off with Express, 
// but feel free to use whatever libs or frameworks you'd like through `package.json`.

// http://expressjs.com/en/starter/static-files.html
app.use(express.static('public'))

// http://expressjs.com/en/starter/basic-routing.html
app.get("/", (request, response) => {
  response.sendFile(__dirname + '/views/index.html')
})

// Simple in-memory store
const dreams = [
  "Find and count some sheep",
  "Climb a really tall mountain",
  "Wash the dishes"
]

app.get("/dreams", (request, response) => {
  response.send(dreams)
})

// could also use the POST body instead of query string: http://expressjs.com/en/api.html#req.body
app.post("/dreams", (request, response) => {
  dreams.push(request.query.dream)
  response.sendStatus(200)
})

// listen for requests :)
const listener = app.listen(process.env.PORT, () => {
  console.log(`Your app is listening on port ${listener.address().port}`)
})
for json part:
{
  "//1": "describes your app and its dependencies",
  "//2": "https://docs.npmjs.com/files/package.json",
  "//3": "updating this file will download and update your packages",
  "name": "my-glitch-app",
  "version": "0.0.1",
  "description": "What am I about?",
  "scripts": {
    "start": "node server.js"
  },
  "dependencies": {
    "express": "^4.16.3",
    "bcrypt": "^3.0.1"
  },
  "engines": {
    "node": "9.x"
  },
  "repository": {
    "url": "https://glitch.com/edit/#!/my-glitch-app"
  },
  "license": "MIT",
  "keywords": [
    "node",
    "glitch",
    "express"
  ]
}
14

listener.address().port? where did this come from?

and this too

request.query.dream?

15

the version is right

16

It was already in there when I clicked the link FCC gave in the server.js

17

then you are not doing anything wrong

did you run npm start at the terminal?

18

How do I run npm start and where is terminal?

19

It sounds like the node package hasn’t been installed. Did you run the npm command to install the bcrypt package in node_modules?

Open up your terminal or command prompt, cd into your project folder root folder, and use npm install bcrypt --save
