Welcome to the course! Thank you for joining us, we hope you enjoy it. A few notes before you get started:

Setup Your Workstation

This document was last revised on January 25th, 2021

This course was originally released in 2018. Since then, the Node.js platform and ecosystem has continued to evolve. Here are the important changes that have happened since then, that you should be aware of:


New version of Node:

The current stable version of Node (as of December 2020) is 14.15.1. That's the one you should be downloading and using.

You can download it here: https://nodejs.org/en/
You can read the docs here: https://nodejs.org/docs/latest-argon/...


Use fs.ftruncate instead of fs.truncate

In newer versions of Node, the name of the function used for file truncation has changed. As you watch the videos, you'll see us refer to fs.truncate. You should be using fs.ftruncate instead (notice the exta "f" in the function name). You can see examples of how to use it here:

https://nodejs.org/docs/latest-v14.x/...

https://nodejs.org/api/esm.html

and take careful note of these caveats:
