A - Architecture and High-Level Design
Explore the key components of a frontend architecture, including the server, view, controller, and model/client store. Understand the importance of separation of concerns and the decision between server-side and client-side computation. A well-structured architecture is crucial for building scalable and maintainable frontend applications.

Understand the trade-offs and choose the right API design for your project. Plus, learn about common API considerations, like status codes, throttling, and pagination.
O - Optimizations and Deep Dive in Frontend System Design
Dive deep into optimization strategies for performance, network efficiency, and user experience. Learn about network optimizations, bundle splitting, rendering, server-side rendering, CSS best practices, application caching, and mobile-friendly design.

@varagor23 8 дней назад

Love the video. One caveat, though. I don't think MVC is a very used pattern in front end design these days. React pretty much killed MVC and the concept of separation of concerns (at least in the traditional sense). Otherwise the video is great!

This is a great video and you have covered a large amount of topics in a short time. I do have a few thoughts. 1. I would spend little more time on the actual UI development strategy - SSR/CSR, state management, UI library considerations, responsive design choices, virtual dom based scrolling, interactivity etc 2. Some of the biggest challenges in building a news feed on frontend are - scroll performance and data fetching - I think that needs to be given special attention 3. Back of envelope calculations need to be frontend focused - what amount of data the component needs to render / filter / parse, how often data needs to be pulled from server and how often, how often the component nees to be repainted on screen,how many dom elements in the compoent etc . These will determine caching strategy, choice of rendering - canvas/svg/plain html/webgl etc,

@shivam_bhalla 21 день назад

Thanks! The goal of this video was not to walk through a specific question per say but rather discuss Frontend System Design interviews holistically. I generally agree with your points, thank you for the feedback :D

@JulieYue 7 месяцев назад

Love this video! Creating a diagram gives a great visualization of need-to-know concepts. Just out of curiosity, which pattern would be best for a Next.js application? In your opinion, is MVC or MVVC better?

@shivam_bhalla 7 месяцев назад

Thanks! One over the other isn’t better, it depends on the use case. For interviews, to keep things simple, I recommend MVC

@titolstwo День назад

Genuine question - if we're comparing HTTP protocoles, shouldn't it be HTTP2 vs HTTP3? HTTP1 has been superseded by 2 & 3 a while ago and I don't see any use cases unless for legacy reasons

@CathalMacDonnacha 9 месяцев назад

Great job. Would you still use the MVC pattern when using React? Since React is really just the 'V' in MVC.

@shivam_bhalla 9 месяцев назад

Thank you! During the system design interview, it’s framework agnostic, you can refer to any design pattern, MVC, MVVM, it’s your preference, I find explaining MVC is a lot easier. Regarding actual development, I prefer to use an MVVM pattern for react, more information on how that works can be found on this article (I will create a video to explain this design pattern in react) paulallies.medium.com/clean-mvvm-with-react-and-react-hooks-ebc37b22542f

@ccy0246 7 месяцев назад

Bringing MVC pattern in your discussion mean you're kind of covering backend architecture as well isn't it correct ? I'd think the frontend would only come into the "View" part. So is it still good idea to talk about MVC pattern when you're focused on Frontend system design ?

@shivam_bhalla 7 месяцев назад

MVC is a design pattern and isn't limited to the server. Scalable client applications (not just web, like iOS/Android) should always be built with a design pattern in mind. Take a look at this article medium.com/swlh/elements-of-mvc-in-react-9382de427c09

@rushilsaraogi3917 5 месяцев назад

I was a little confused by the http1 vs http2 part, what's the point of bringing that up? When would you choose http1 over http2?

@shivam_bhalla 5 месяцев назад

You wouldn’t choose http1 over 2, the goal here is to give you enough context between the two so that you can explain to the interviewer why you chose http2 (keep it short and high level)

@thecarrotdude 5 месяцев назад

I'm not sure if the MVC pattern discussion and diagram are necessary to talk about in this type of interview. At least in the video, your discussion of it wasn't really specific to the feature being asked about. It was almost a generic discussion of how data flows in MVC pattern.

@shivam_bhalla 4 месяца назад

This video is meant to be a high level overview of Frontend system design fundamentals with using designing Facebook as an example. It’s important to demonstrate and be aware of various design patterns for if and when they come up.

@thecarrotdude 5 месяцев назад

Another issue is with your discussion of the API options. You describe what each one is, pros and cons, but you don't explain WHY you picked graphQL over the others for this use case.

@magdaz3562 5 месяцев назад

Also at some point the Author said that graghQL is a protocol, which it isn't, it is simply HTTP POST
