Working with NPM is mandatory foundational knowledge as you learn Node.js. Node Package Manager (NPM) allows developers to create shareable modules and share them with the world - including us! Instead of re-creating the wheel, we can search for existing packages to import into our projects that meet our needs.

You're welcome!
Good intro to NPM,
I like NPM but I often see people install a lot of dependencies just to get benefit from some basic stuffs,
Thirsty for more coding,
Thanks Dave
Very true, Ahmad. It can be abused. At the same time, it has many good uses and is foundational knowledge for working with Node JS. Thanks for the comment! 💯
Learnt a lot 💯🔥
Glad to hear that!
Bro, this video about Nervous Penpal Message, taught me so much and at a fast pace. Uni profs should take note of you.
Thank you! I do teach part-time (adjunct) at a university, too. 💯
Thank you again

npm as a "Ninja Pumpkin Mutants" i like it! 😂

How do you say “nodemon”?
Probably everyone: “node mon”
Me at 2.30am on a school night: “no demon!!!!!”
😆
Maybe you should apply for a lecturing Job Dave
Thanks - I was previously at a university full-time. Now part-time university and full-time dev.
hi Dave Im using the latest version of node. One thing i noted when using the function to format date fron date-fns. the syntax as you write it result in application crash telling me date is not defined. the variable date need to be defined first like const d = new date(). then we use the date format function: console.log(format(d, 'yyyy-MMM-dd') then i get the proper result.
You must have missed where I created the new date because I did not crash and this has not changed due to a Node release.
hey Dave, I know this is off topic. but can u explain this function.
const range = (start, stop, step) => Array.from({ length: (stop - start) / step + 1}, (_, i) => start + (i * step));
from mdn under array.from
as well as
let range = {
from: 1,
to: 5
};
// 1. call to for..of initially calls this
range[Symbol.iterator] = function() {
// ...it returns the iterator object:
// 2. Onward, for..of works only with this iterator, asking it for next values
return {
current: this.from,
last: this.to,
// 3. next() is called on each iteration by the for..of loop
next() {
// 4. it should return the value as an object {done:.., value :...}
if (this.current
Definitely off the topic of this video tutorial, but I could do a tutorial on the topic you are asking about sometime. 😀 MDN is a great source to look up each part of your question such as symbol.iterator: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol/iterator
thanks. I encountered some problem installing nodemon... It cannot be run after installation: "nodemon : The term 'nodemon' is not recognized as the name of a cmdlet, function, script file, or operable program. "
Follow their installation guide here: www.npmjs.com/package/nodemon
I have one issue!!!
When i type 'nodemon' and enter after installing it terminal gives error that first it gives path and then it says script is disabled on this system. Anyone can give solution of it.....
is there a repo of this node course in your github?
Hi Michael - not for the first 5 chapters as they are only examples. Starting with Chapter 6, each lesson has source code available here: github.com/gitdagray/node_js_resources
whenever i type this command "npm i nodemon -g "
it shows this
changed 32 packages, and audited 33 packages in 1s
3 packages are looking for funding
run `npm fund` for details
found 0 vulnerabilities
i then went ahead to type nodemon in the terminal
and i get this
nodemon: command not found
any advise to give please
The first part of the message is a standard type of return after installing a package with npm. The second part - why just type nodemon in the terminal? It must run on Node. In this video, I believe I show how to set up the script you need in your package.json file to run it.
solved it
@@DaveGrayTeachesCode solved it thank you
@@kingsleyunorji5044 how please , i'm facing the same problem
First, I want to say thank you and great job with this video. However, even though you say for beginners, I feel your tutorials are hard for someone who's not familiar with what your teaching and is actually a beginner. When i watch your tutorials, i need to go learn elsewhere first then come back here to enhance what i know and even at that the new concepts i get from your video are always hard to understand. Just constructive criticism, great video still!
