How I'm Mastering Node

January 24, 2020

Node is weird.

If you've built any significant app with JavaScript, you've used Node. You've used npm or yarn, used import syntax and are familiar with require syntax.

But... does that really mean you know Node?

I've built plenty of apps with Node. I still don't feel like I understand it, though. I just wrote browser-based JavaScript and didn't open a browser, basically.

I've been trying to find the missing links with Node (and back-end programming in general) and have been going through the extremely good Node course from Andrew Mead. I highly recommend it if you've never written Node before.

However, I'm at a weird middle ground with my knowledge where I am familiar with a lot of Node concepts, I just haven't put them together in a unified Node-first way yet.

Let's list what I consider myself familiar with:

  • fs & the Node API in general
  • how to make API endpoints (although not without Express)
  • npm/yarn
  • command line arguments
  • promises & async/await (although I have never used this outside of an AJAX environment)
  • event loop / callback queue

Here's what I'm not familiar with:

  • streams
  • buffers
  • how to publish a package on npm and make it importable & usable
  • callbacks without the context of AJAX, aka how to make a callback for callback's sake
  • how http works in Node???
  • testing Node
  • connecting to databases???

So, I know a lot of individual concepts, I think I'm missing a lot of the connections, though.

I could get those connections if I sit through the 30 hours of Node that Andrew is presenting in his excellent Udemy course, but I no longer want to. I know too much to feel satisfied with spending more time there. I have to force myself to go through it every day and I don't feel like I'm learning at a fast enough pace given my prior experience.

So, let's not.

I need to figure out a better way to learn this stuff.

This is how I know I'm getting to the level where Udemy isn't as appealing and faster-paced resources like Egghead & PluralSight are. Give me an overview of the concepts, structure, and vocabulary in less than 5 hours, so I can work on something myself. That might even be direct work tickets.

But how do we get that list of essential concepts to learn?

Especially if we're skipping large, comprehensive courses like Udemy's from now on.

My big issue with Node is that I don't know what I don't know. I have no idea what streams are and why I need them. So, if specific Googling about Node (or an Egghead course) doesn't cover it, I'll still feel like I'm missing something.

Right now, the only answer I have is to ask folks. Twitter is good for this.

Otherwise, I'd say if Twitter didn't exist, I'd just find the top 10 books on the topic and summarize all the commonalities that show up again and again. Don't skip anything even if it sounds obscure.


So, here's what I'm using for resources for Node, now that I have a good list of things I need to learn from Twitter and reading around.

The most important resource on this list has been Anthony Alicea's Node course. It's the best course to understand Node deeply.


The most important way to make progress with this is to make projects that slowly but surely allow me to practice all of these concepts at least 3x. This was covered before in How I Learn.

I built two capstone projects that cover most of the topics that I felt I was lacking.

Firstly is rashee, a CLI app that grabs your horoscope for the day. This uses CLI arguments, HTTP, npm, etc..

Secondly is radhikaisms, a tiny end-to-end Node app. This only uses one library (to import the Postgres database), and otherwise builds an API that connects to a database + a front-end to add new stuff to do the database using only Node (and HTML/JS for the front-end).
