Create a new, separate folder somewhere on your machine:
$ mkdir nodejs-week2
$ code nodejs-week2 # to open the folder in VS Code
You can also reuse some other folder. Main thing to watch out for is that the folder you decide to use should ideally be empty.
Initialize and install:
$ npm init -y
$ npm install express mysql2 knex
Make sure you have "type": "module" in your package.json.
Create a file named app.js and use the following as a starting point for this exercise:
import express from 'express'
const app = express()
const port = process.env.PORT || 3000
app.get('/', (req, res) => {
res.send('Hello Class!')
})
app.listen(port, () => {
console.log(`Listening on port ${port}`)
})$ npm install --save-dev nodemon
$ npm set-script dev "nodemon app.js"
$ npm run dev
Go to http://localhost:3000 in your browser to verify that the server started.
