basic instructions for setting up an express project.md

Set up the folder (either by creating a repo on git and cloning it OR by creating a new folder in a workspace).

Inside the newly set up folder, open Terminal

Run "npm init" to initialise Node Package Manager "enter" to accept defaults

Install Express "npm install express --save" (--save adds the package to the dependencies list)

Install Jest "npm install jest --save-dev"

Install BodyParser (so that we can receive JSON) "npm install body-parser --save"

Install Handlebars "npm install hbs --save"

Install Fetch "npm install node-fetch --save"

---

We will need to initialise all the components in the relevant js file

const express = require('express'); const bodyParser = require('body-parser'); const app = express();

const fetch = require('node-fetch'); // if using fetch

app.use(bodyParser.json()); // parse incoming JSON app.set('view engine', 'hbs'); // use Handlebars as a view engine

// only if returning object app.post('/pathOfURL', function (req, res){ res.json(req.body); // body = body of the request });

// only if using Handlebars to render template app.post('/pathOfURL', function(req, res){ res.render("nameOfTemplateFile", req.body) // body = objectSentToPostReq })

// add listener so that we can access what we're working on app.listen(8080, function(){ console.log("listening on port 8080"); });
