Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a web browser. This course is your guide for learning the fundamentals of Node.js.

In this course, you'll start by understanding the inner workings of Node.js. More specifically, you’ll explore its features, how event loops work, and how multithreading works. You’ll then move on to the fundamentals of Node.js like file systems, global objects, and the Buffer class.

In the latter half of the course, you’ll explore more advanced concepts like modules,  events,  and packages. At the end of this course, you will get hands-on with Node.js and create your own food delivery web application.

By the end of this course, you will have a new, in-demand skill to put on your resume and a cool project to add to your portfolio.

Learn Node.js: The Complete Course for Beginners

# Installing Node.js
Being cross-platform, Node.js is available on a number of different operating systems. Head over to their download page [here](https://nodejs.org/en/download/) to download it on your machine. You can choose between the #key# LTS: Long-Term Support #key# and the latest version.
> This course was written with Node.js 14.8, which was the latest version at the time of writing. 

# Installing packages
It is very easy to search for packages on the npmjs [website](https://www.npmjs.com/). Most packages have very resourceful pages with links to the official documentation and the github pages. You can install packages using the following command.
```
npm install <package>
// for nodemon
npm install nodemon
```
To install a specific version of a package we can use the following command:
```
npm install <package>@<version>
// for nodemon
npm install nodemon@1.18.7
```
We can also specify the latest version of a minor or a patch if we want. Let's say we want nodemon 1.19, and we don't care about the patch. We can get the latest version of the patch by using the `~`.
```
// for nodemon
npm install nodemon@~1.18.7
```
This will install the latest version of 1.18, which is 1.18.11. We can do the same for the latest minor version using `^`.
```
// for nodemon
npm install nodemon@^1.18.7
```
This will install version 1.19.4 of nodemon, even though version 2.0.4 exists. The `^` gets the latest version of the *minor*, whilst keeping the *major* the same.

Here is a list of a few other flags for `install`.
|**Flags** | **Explanation** |
|-|-|
| `-P, --save-prod` | This is the default behavior. This will save the package in your dependencies. |
| `-D, --save-dev` | This will save the package in your devDependencies. |
| `-O, --save-optional` | This will save the package in your optionalDependencies. |
| `--no-save` | The package will not be saved as a dependency. |
> Packages can be uninstalled using the `uninstall` command. We can use the same flags as the `install` command; however, instead of saving the package, we can choose to remove the package from our dependencies with the flags.

# Updating packages
Packages can be updated easily with npm. We can use the `update` command to update the packages.
```
npm update
```
The `update` command has a couple of flags that can be used to modify its behavior. The `--dev` flag also updates the `devDependencies`. The `-g` flag will update globally installed packages.

# Docs
You can view the official documentation [here](https://nodejs.org/en/docs/). Since Node.js is always improving and getting new features, the documentation can be really useful for staying up to date. [This](https://node.green/) website  provides a nice overview of all the supported ECMAScript features in various versions of Node.js.
