NestJS Beginners Guide - Part 1: Core Concepts and REST API
In this first video of my series I explain some of the core concepts of NestJS including Modules, Controllers, Validation Pipes, DTOs and also build a simple REST API with CRUD operations around that.
This series is meant to teach the fundamental concepts of NestJS through a real-world application. I will guide you step by step through the entire process of building a scalable, testable and industry level application using the power of NestJS.

Don't Use The Wrong Query Function Again!
Просмотров 915 месяцев назад
Using the wrong query functions can cause unexpected testing behaviors, and the Jest documentations doesn't make it clear on when to use each type of query functions. Until you try and test a lot yourself, you'll start to wrap your head around it. So, in this video I will show you when to use what. There are 3 types of query functions: getBy, queryBy or findBy. - Github repo for this video and ...

Interfaces are NOT types for objects. Here is the real answer.
Просмотров 1576 месяцев назад
What if I told you that interfaces are NOT meant to define a type for objects? This is a common misconception in the community since modern frameworks put heavy emphasis on functional programming over OOP. In this video I will show you how to really use interfaces to build powerful applications that are modular and reusable. The 2 benefits of interfaces as mentioned in the video: 1. Creating a ...

Another great video!
I'm double sharing. Keep growing 🚀
thank you very much
@@madaraT-fg8kq you’re very welcome! Are you looking for a specific topic in tech?
@@markmaksi no, I have never done unit testing, this video is a great start and also gave me confidence.
@@madaraT-fg8kq yep testing is scary for most of us, and it’s not liked among the community in general. To me I guess it’s fun although sometimes it’s tough. I’m glad it helped you. :)
❤
Great video Mark!
One important thing I forgot to do is to mark our DTO properties as "readonly" for immutability. :) 🌟Support my content and work and buy me a pizza here: buymeacoffee.com/markmaksi ⭐ GitHub repo for this series: github.com/mmaksi/nestjs-series
Hi Mark, great topic to to make video. Great content. I can suggest to prepare more what you want to say, as I can feel you repeat the same things several times. Despite that I will watch you content and subscribe. Hope you do more videos.
Thank you for your support and feedback! Yes, I'm preparing a series on mastering NestJS. I will publish the first video soon. :)
Good video bro!
I thought kafka will do the communication between containers. would appreciate do a video on this communication methods
Interesting stuff. I never got the hang of throwing and catching Errors as a way of managing code flow. I realize it's the done thing but I won't change my ways now. AFAIK, Promises and uncaught Errors go poorly together. If you don't catch the Error before it gets to the Promise, things stop. Since I don't want my server to stop, I consider Errors to be like nitroglycerin. Internally, I prefer to just use return codes, in the spirit of 'not-found', 'nothing-to-do' and 'unauthorized'. More complex than that: a return object, I guess. So it's like an Error but without the danger factor.
Well, I always do try/catch for promises to avoid the unhandled promise rejection error as you stated, and I throw a specific error. If it was a general error that I didn’t handle, the middleware will do the job and throws 500 internal error or 400 bad request. Returning objects isn’t wrong, but gets repetitive very quickly and also no centralised place to handle errors. I’m not fixated towards one approach or another. I prefer to learn what every approach has to offer.
@@markmaksi "gets repetitive" That's no lie! The nature of our stuff is that these are flung out into the world so the idea of centralization is different than you might imagine. We spend a lot of thought on sifting events to be explicitly sent upstream. "try/catch for promises" That makes sense. It seems strange to have to do that, no? I never got the hang of using the 'reject' of a Promise. If it failed, we resolve with an error code in the status object.
Great work mark!
Yeahhhh, quality content
tHanks
you need more subscribers for sure
Insightful content!
great content mate, pls use typescript for projects
Thanks for the feedback! All my current projects are in TypeScript. :)
Please make the font bigger?
Would like you to take us through handling user authentication in express, node and typescript, and using sequelize postgres. Thank you
Yes of course! I am currently planning for 2 videos that aim to teach how to prepare production workflow: next.js app > write tests (there’s a playlist on my channel) > create CI pipeline using github actions > docker container > deploy to AWS EC2 instance. It’s all made for beginners. After that I will make that video that you have just requested. :)
@@markmaksi Thank you. Looking forward for more. God bless your for your commitment and sacrifice.
Wonderful explanation.
will be videos how to create docker files?)
Yep of course. The next video is how to prepare a production workflow: dockerize next.js app > build a CI pipeline > deploy to AWS EC2 instance. It’s coming this weekend. Thanks for following my content. If you have ideas in mind regarding docker or other topics please let me know. 😎👊🏼
To be honest I never seen such a great tutorial on RUclips in terms of Docker especially when it comes to -i for STDIN and -t for STDOUT commands explained in a very short video !!! Awesome work !!! Regard from Pakistan
Thank you for your kind words. I’m glad you enjoyed my video. Thanks for the support. ♥️
Great explanation brother.
Another superb video on complex subject
Thanks brother!
Good videos here. Thank you
You're welcome! Glad you liked it. Feel free to check out my blog post around authentication and authorization where I shared what I wish someone told me in the beginning of my career: markmaksi.hashnode.dev/fundamental-authentication-concepts
the lack of runtime type safety has always been the deal breaker for me with typescript. to even simulate that you need libraries that are verbose and complex.
Property 'toHaveTotalPrice' does not exist on type 'JestMatchers<{ id: number; name: string; price: number; }[]>'. thank you sir mark. i watch to 4 videos, i get a problem on the custom matcher using typscript. i code along with your video then as im trying to import the toHaveTotalPrice.. i got this error. someone my also bump on this error. its just syntax error for ES6. here is my updated code. //Cart.test.ts test("checks if the shopping cart has the correct total price", () => { const items = [ // array of items ]; expect(toHaveTotalPrice(items,60)) expect(toHaveTotalPrice(items, 50)).not.toBeTruthy(); });
Awesome video.
Nice work on this complex topic. Perfectly Explained. Thank you
Hey bro! One minor constructive criticism. Start making timestamps for your videos. Will be easier to look thru what you have coming up and then look carefully on those topics within the videos.
Great suggestion! The point is that RUclips doesn’t create the time stamps if you didn’t start with 00:00
@markmaksi yea just Mark that as 00:00 Intro
@@TimoTalksTech yes but I didn’t know this and was just wondering what’s going on LoL 😂
Top notch stuff as always! You should have 1000 subs already ❤
Thanks bro! I hope I get that soon! I want this channel to be fully educational and drama-free.
it was helpful, I hope you'll find time to make next video)
Thank you! It's not a matter of time, but my views dropped dramatically after posting 4 videos on Testing. Now I'm preparing for a hot video for the coming weeks, tests will be there but not the main topic, but it's gonna be a great one. I'll drop different videos before that hot one is ready to be released. Be ready for it!
testing is not so popular topic... and find something that is matching with you can be difficult
thank you very much!
Welcome! Are you looking for a specific topic in testing?
great video mark!
Thank you!

Nice one Mark! Learnt something new
Thank you! Glad that you found it helpful!
we was having all this pain now bun took the pain away 😂 and we run directly the Ts files
I love deno! Its community is growing but hopefully it takes over node one day. 😂
Types and interface has these own place is typescript, mark has done a grt job summarizing the concepts
Thanks bro!
Good video!! .You've saved me. I've been awake for 24 hours and I have to submit a project in a couple of hours for a job interview. Greetings from Argentina!
I'm glad you find the video helpful! If you need help feel free to reach me out on X. Good luck and hope you land your dream job!
I can relate , hope you landed the job
this is interesting 😮 i need to try all this ..
nice 👍 keep going 💪, we need more testing Stuff.
CAN you do next 13 or next 14 api app router test, maybe with prisma too? I'm lost with mocking
I no longer use Next 13. For the app router API, yes I can do that. The series starts from a beginner level so it’s gonna take a while until I cover more advanced content. What exactly are you struggling with?
Amazing to see your new video again! Good stuff as always! You are really growing fast! Keep crushing my man!
Thanks brother! Hard work + passion. 🔥
Thanks Mark!! great tutorial
can you do a favor though: next time add chapters/sections to your vid so we can easily refer back to different parts
I haven't even watched the video yet, but already gotta say, thank you! For me it was never a debate as conceptually they represent different ideas, so it was all the more surprising to me as to how many youtubers recommend to always use types (unless interfaces are explicitly needed). Types are shorthands, interfaces are strict, non-dynamic structures for objects. Therefore I use them as such.
That’s very true. When I see a RUclips thumbnail made for clickbaits of use types don’t use interfaces.. I just shake my head. I remember seeing a video where the content creator said “I can’t believe the docs recommend you to use interfaces”. I digged deeper into that RUclipsr and they claimed to have 10 years of experience in software development. 🤔 I really can’t see the point of: 1. Talking about a topic we don’t have knowledge about. 2. Repeating what others say in different format without testing the validity of their information. I wish this video goes viral so that I create some trouble in the community for good. Thanks for your knowledge and can’t wait to hear your feedback on the entire video. Also a hashnode blog is also available in the description box.
