Every NestJS Concept Explained in 9 Minutes

[@lautaroleonhardt2600]

This guy summarized key concepts in less than 10 minutes. It saved me thousands of hours

[@Ba2sik]

The fact that you explain with a smile on your face makes it 10 times better, thank you! :)

[@pitsonborellio7463]

I've followed a lot of dev teachers but you are really unique, everything looks simple with you. Additionally your smile 😁 makes it easy to digest the information. Thanks for sharing your experience 🙏

[@lageekattitude]

Thanks for the excellent explanation. I've shared the "Master NestJS with these Guides" playlist with my team. We recently migrated our backend from Directus to NestJS, and your tutorials, combined with the clear NestJS documentation, have been a lifesaver.

[@TechVisionExplained]

@israeltechint Wow thank you so much for the feedback and really happy that my videos are being helpful to you and your team. Thank you for taking the time to leave a comment and sharing the videos, really appreciate it 💜🙏

[@DrJub]

Why did you migrate away from directus?

[@lageekattitude]

@@DrJub It's a good headless CMS but customizing it to get what I wanted was slower than building a new API.

[@lageekattitude]

I had to create a lot of custom extensions, add tsoa and others packages to have a flexible developer experience. That's not the best for collaboration. At least, now that we use Nestjs for the Backend and Refine React for the admin app, we are more confident when reacting to changes in business rules.

[@asahfikir]

Love the way you explaining things in a very consumable chunk. Easy to digest.

[@VaibhavSomani-b1c]

This guy has a very likable personality. Kudos.

@@TechVisionExplained Which ORM would you recommend me to use for an application with many users ?

[@TechVisionExplained]

​@@kenbinta2246 Have you considered not using an ORM 😅? Before adding a tool/library/layer you can ask yourself these questions? - What is the problem I'm trying to solve? - Is that problem worth solving? - Is that problem worth solving now? (Do I have the time and budget for it) - Does the tool/library/layer I want to add introduces more complexity? If yes is the added complexity worth it? - If you work on a team, are your team members happy with the change, are the happy to learn something new, do you have the time and budget for everybody skill up? This was my very diplomatic way of saying, if you're not sure about which ORM to choose , don't use one 😀. Plus you can always come back and add one later if you want to.

Your smile is something :) My mood is just so uplifted by looking at your smile. Thank you for the explanation, it's very clear, I'm new to Nest.js and it was very clear to me!

[@TechVisionExplained]

Thank you so much for your comment, that's amazing to hear I always wonder if my explanation makes sense I try to put some metaphore here and there, some diagrams etc... Getting this type of feedback really makes me super happy, thanks for watching the video and leaving such a nice comment 🙏💜

[@ignaciovillarruel123]

I really enjoyed the example of middlewares with airplanes. amazing video!

It was a great explanation of Nest.js concepts. Keep making these short videos on Nest.js framework.

great video, i have interview in few minutes and your video helped me to go through the nest js quickly, thank you for that !!!!

[@mateussoares7599]

good explanation man, im loving nestjs. thumbnail and editing are also on point, i can see that you put effort into this, amazing for such a small channel

[@TechVisionExplained]

Thanks a lot for this comment 🙏, yes indeed there is a lot of effort that goes into these videos and comments like yours give me the motivation to keep going

[@sunnysetia]

Really quality video, can tell by your editing you are putting a lot of effort into it. You explain things in such a way that it is super easy to understand. Would love to see some more mini tutorial type videos demonstrating specific features e.g. recently I came across event emitters in nestjs but am not sure in which case they are useful and how to use them. A video on this will be quite helpful. Would also love to see a video on best practices for preparing it for production and deployment. Best practices for logging so that if in production something breaks we can check it. Keep it up!

[@TechVisionExplained]

Hey @sunnysetia, thank you so much for your comment, and also thank you for being a recurring viewer of the channel. Deployment and logging are definitely on my very long backlog list of topics I want to cover relatively soon. But to be totally transparent, event emitters were not really on my radar. I'm currently working on a crash course on Microservices, and I'm really looking forward to publishing that (probably next month). But in the meantime, I'll be releasing other mini-tutorials and explainers 😉

[@sunnysetia]

@@TechVisionExplained looking forward to it!

[@chinmayghule8272]

Excellent video, but I think two things can make it better: 01. Beginners might need multiple examples for the same concept. It would've been nice if you gave 3 examples to explain each thing. 02. The last section, relating to the layers of working of Nest.js, was too much technical jargon. Although I understood that part because of my slight familiarity with those concepts, a beginner might get too confused about it.
