Hi, I'm wondering whether I should be using immutability for my functions or not(I've done mine without and tested it out and it seems to be working fine), additionally using immutability consumes more data storage from what I know, and for a larger amount of data that could come into play, afterall im updating the existing database always and not creating a new one so it shouldnt be required but maybe its better viewed or actually is better in some other way or maybe I'm supposed to use it interchangebly depending on each case? Thank you for your great videos

6:49 how we handle put and delete to this path without dinamic paramethar like :id?

Hi Dave, cool node+express series, as well as a channel in general, I love the way you explain details. Can you advise if there is some balance between the amount of code in Routers and Controllers? I'll explain a bit. I had 90% of all my code directly in the Routers, inside the "(req, res) => {}" functions, I thought the code would work faster, neglecting the convenience of writing, refactoring, etc. I had literally thousands of lines of code in my routers.
Recently I've redone everything and transferred all my code to the respective controllers. However, I believe, there should be some balance between the two. A lot of similar imports in my controllers make me think about some sort of inefficiency. I came from very ancient languages like Assembler, Basic, Pascal, etc. :)) where repeating was treated as something very bad and inefficient, even an extra semicolon was bad)) not to mention entire models or other controllers. The logic behind was really simple - the compiler will bring all the imports into 1 file anyway. I realize that the browser does not compile JS))) however, the entire chain ends up on hardware anyway... Thus I'm wondering about your approach, experience, or even thoughts in this regard, thank you in advance.

Beside organizing the code, what I really like about MVC design pattern (or alike) is that we can separate the code facing the outside world (controller) from other codes dealing directly with the data (model),

regarding createEmployee handler, getting a new id by incrementing the last employee id will work fine as long as our data is sorted by id (which is the case here), but if we for some reasons have the data unsorted or sorted by something other than id then I think it cold be better to find the max id + 1
anyways, using a real database engine IDs can be auto generated,

for the unsortedArray.sort function, although it's much clearer this way but it can be made shorter by returning a.id - b.id (I think you mentioned this in a previous video but don't remember where)

Thanks Dave for keeping us thinking

Thank you very much.

In this lesson (after copy-pasting your source code) -
Thunder Client doesn't respond to requests
While the server runs on port 3500.

It did work during the Router video (where I manually wrote anything you did).

[jinlu]

Can we just use sort((a, b) => a.id - b.id) instead of sort((a, b) => a.id > b.id ? 1: a.id < b.id ? -1 : 0) in updateEmployee when sorting the array?

[TheRoseWoodBody]

Hi, Dave! First of all - thank you for all the great tutorials!

I have a question about response data transformation. Should it be done in the controller layer or should there be an additional "service" layer between the controller and the model?

Thanks!

[deepikaarava]

Hi Dav, Grate tutorial, Thank you for that. I have a question we have different libraries for API development expressJS, NestJS many more can you suggest me which is best for a realtime steaming application which should read data from a data bricks server continuously

[piotrekjazz]

I took a small brake because the Course became very advanced. It is hard to progress building the project at the same time when it is at the beginning level. Now I am practicing very basic "Express JS Crash Course" by Traversy Media youtube channel, but I am coming back soon, and surely I will finish it.

[skyhs]

I have a question on part 14:20. When you run employee.firstname = req.body.firstname, wouldnt it mutate the existing employee object in the existing array? In that case isnt it unneccesary to remove the object from array and add it again?

[ahmetkaya]

For sorting the array in ascending order with respect to employees' id in the updateEmployee() function, it would be better the usage below. Just as a recommendation.

data.setEmployees(unsortedArray.sort((a, b) => a.id - b.id))

Could you please upload a video that explains authentication; like how to consume a signup and a login endpoint with Javascript or react? thanks
