Thanks a lot!!
You are the real superhero here!!!!!!
Bud your videos are really concise. Great job.
Exactly I was looking for this. Thank you Pedro.
This is a very good video. You explain non trivial concepts in a very easy way. Keep up the good work.

P.S subscribed
Só tópico relevante por aqui! Thanks.
Well explained!
Amazing Video Bro.. Keep it Up
great video pedro
How does the View part of MVC fit into the project folder structure? A backend or API project seems to focus on Model and Controller folder structures but how does the View part fit into things? Presumably, it's simply a front-end project separate from the back-end project with its own folder structure, such as a React project with folders such as components containing .jsx files and maybe an API folder containing HTTP request code to call backend endpoints using something like Axios as the HTTP request package? Would frontend and backend be in separate VS Code projects or maybe with both project folders in a VS Code Workspace structure? Haven't used Workspaces so this may make a good topic for a separate video in itself?
🔥🔥 very helpful video
amazing!
Amazing Pedro
Thank you!
Vlw, Pedro!
Even though this is a backend example, I think you should still somehow cover the 'View' from the MVC!
The view is how you present the data, not views or screens.
very helpful
Thank you.
thanks man
Amazing
I have one question about controllers and proper design. Can particular controller use multiple services? Or rather one controller should use one service, but for example serviceA can use serviceB, serviceB, serviceC?
thankyou bro
Awesome
MVC is a nice topic for a drunk conversation) When you switch a context between BE/FE/full application or different technologies/languages, it oftentimes changes the meaning. Same for the other patterns.
Nicely explained bro🤘
Glad you liked it
Ih rapá um brasuca, estamos em toda parte mesmo kkk
banger!
top, mate
Could you please make a content the difference between exertnal and internal API?
What about scenario when Multiple Database needed to be integrated in a CRUD Web app, because then we had overhead of extra *.service.js files as each controller will need separate service/Table files to call to. Could we optimize it somehow, so that it could be done in minimum no. of *.service.js files for Multi-DB (MongoDB, PostgreSQL, MySQL, Cassandra etc.) ???
good explanation
Thank you!
thanks buddy but it won't be a problem if I won't use server directory and only i depend on controller ??
Did you talk about the "models" folder? What's its purpose?
bro where is the github link for the repo?
Estuda a quanto tempo? se puder fazer um video contando sua jornada ate aqui, quais foram suas dificuldades no inicio e tals. Feliz em ver um brazuka fazendo video de programacao em ingles. Keep going bro
Pode ser um bom video! Eu programo a 4 anos mas web dev somente a 2
Where according to you is the best place for input validation ?
As a middleware that I pass in the routes folder!
@@PedroTechnologies Is this also known as error-handling middleware? Maybe including middleware for error logging using packages such as Winston?
create a video on how to host node js express mysql project on cpanel Or Hostinger
What about model?
Thank you. Can you do the video about relations too.
Yes! It is one of the topics I want to talk about!
I'm getting "cannot use import statement outside a module" for all the code in this video.
The code is not runnable! You can use the import statements if you have it set up in your project. By default in nodejs you have to import stuff by using the notation:
const variableName = require('packageName')
For that in package.json
Where there is script { ...... }
Just above it write
type: "module"
@@slowedReverbJunction that doesn't do anything
So with services, models will be useless?
It depends, services is where you make requests to your database. Models is where you define the database schemas / tables. Not all RDMS requires you to define its tables in your project so it might be useless in those cases.
@@PedroTechnologies So Models are sort of like migration, and services becomes sort of like Models.
Add the next: .env file, connection JS file, utility JS file, model JS file, controller JS file, router post JS file, router use JS file, view HBS file, style CSS file
How is it going Pedro
Doing wellm how about you?
@@PedroTechnologies doing good 👍
Hey buddy, this is irrelevant question bt...I created a blog project in react. I devided that project into two parts...user and Admin...What I want to do is I want to implement routing. I used react router dom. Bt the problem is...I use browser Router n switch blah blah..in App . Js...and Added navbar top which will be visible in all components...bt I don't want it to visible in admin area...I want to show admin sidebar in admin panel only...how to fix this?? Is there any solution to this ?? Please help...Thanks in advance n Thanks for your tutorials they have helped me alot... seriously thanks...♥️♥️
You can add a condition asking if the current pathname is not equal to the admin route. Something like {window.location.pathname !== '/admin' && }
@@PedroTechnologies thank you so much... Bt I am new in React...so I didn't understand it well... could you please make a video on this ?? Coz lot of programmers will face this problem...coz every react project requires this....so please...only if you get free time...I will try to do it by myself... Thank you again...Pedro...♥️♥️
@@PedroTechnologies Okay....I will use conditional rendering for this...plz check my code if window.location.pathname=== "/admin" then I will show admin sidebar bt My routes will change...like /admin /addpost /profile so then?? How to fix this ??
The is wrong. The database don't change the representation.
axios.defaults.withCredentials = true
const userLogin = () => {
const app = axios.post("localhost:3000/login",
data,
headers,
{ withCredentials: true }
).then((result) => {
console.log(result)
}).catch((err) => {
console.log(err)
});
}
this code doesnt store jwt in cookies ...but postman does...?? how to fix this ??
