# Node.js

|
|
## NPM
|
|
|
|
Whenever creating a new node project, use to set it up
|
|
|
|
```
|
|
npm init
|
|
```
|
|
|
|
[NPM](https://www.npmjs.com/) is a package manager for node.js and js libraries and frameworks. You can look up packages there, and install them for your project with:
|
|
|
|
```
|
|
npm install package-name --save
|
|
```
|
|
|
|
## module.exports/require
|
|
|
|
Traditionally, importing JS files into other JS files has not been supported... until now! There are several ways to do this, but node allows you to add things the to module.exports object.
|
|
|
|
```javascript
|
|
module.exports = 'foo';
|
|
```
|
|
|
|
Whatever is on there, will be the return value of
|
|
|
|
```javascript
|
|
require('yourJSFile.js');
|
|
```
|
|
|
|
You can assign this to a variable to use later
|
|
|
|
## Instantation
|
|
|
|
First require express:
|
|
|
|
```javascript
|
|
var express = require('express'); //include express package
|
|
```
|
|
|
|
`express` has lots of abilities, but we just want to start up a server app:
|
|
|
|
```javascript
|
|
var app = express(); // create an express app
|
|
```
|
|
|
|
Then make it listen on a port
|
|
|
|
```javascript
|
|
app.listen(3000, function(){ //start the server
|
|
console.log('listening on port ' + PORT);
|
|
});
|
|
```
