And in this module, I'm going to do something

Everything that I did in the previous example,

drawing the map, graphing the global temperature data,

on the web page with the fetch function, all of that

meaning JavaScript written into the HTML page itself.

But there are a lot of things that you, that I,

that the people of the world who were doing this programming

thing want to do, working with data and APIs,

that you cannot do with client-side JavaScript only.

And I'm going to use a JavaScript runtime called

Node.js which can be used for server-side programming.

Now, the details of what server-side programming is,

and how I'm going to do it, that's to come.

But this project that I'm going to build,

we need node for this project is for data persistence.

I want to gather some data, and save it, and get it back later.

And this is not something that you can easily

You could certainly use somebody else's server.

as a service, where I could just be like, hey, you've

And take my data, and then I'll ask for it back later.

But I'm actually going to create a server that's

to need to show you how to get that server

to run somewhere else besides your own laptop,

The project that I'm going to build in this module

And the Data Selfie App is an example project

by Joey Lee who's designer and researcher.

He teaches a class right here at NYU at ITP

And so Joey has graciously given permission

In this video's description I'll link to Joey's website

as well as to the original GitHub repo for the data selfie

app so you can find all of the code for the things

to need to download and install some stuff that you might not

It's going to be confusing, because you might

be using Windows, or you might be using Mac,

So let me give you a list of the things you need

and help you with some resources to find those things.

That should be as easy as going to nodejs.org and following

the installation instructions for your operating system.

I do also have an entire video about downloading

You're also going to want some kind of console application,

some command-line terminal thing that you can open up

and type commands in to run Node stuff on your computer.

I'm using iTerm, which is an alternative to the Mac's

On Windows I hear people like PowerShell,

where I go through all of these bits and pieces of everything

So you can also just go and find that series,

you need some kind of shell command prompt thing,

So before I get to coding and building the actual project,

let's just talk for a second about, what is Node?

Now, if you go to the Node website, it says right there,

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript
