@arjay_mccandless: Clearly I sucks at app dev 😂 #coding #programming #systemdesign

jordan :

guy who makes system design content discovers caching and non-blocking data fetching

shanidani3030 :

this is basic stuff

️ :

Ui needs a bit of work

Evie | Off Script :

Thank you for this, just discovered this in my app

Idan Tal :

So caching

[object Object] :

Is there any reason you're making so many small requests instead of a few large ones? You could have "/api/dashboard" that returns all the data and can even use a single SQL query so it's better for everyone

Ewan 🏴󠁧󠁢󠁥󠁮󠁧󠁿 ☭ :

So you added caching

Sailor Moon’s Side Dude :

Would assuming the user is already logged in be an optimistic antipattern?

Akin | Macro Simple App :

Why are you not local first?

Herr Perfekt :

Seeing your other videos, App dev isn't your main strength. Or is it just for the tutorial?

browsecomments :

thanks for sharing! 👌🏻 I was nervous you're gonna tell us the solution was redoing the app in rust 😂

William :

You could just use skeleton loaders for the data that may update without the UI being updated, so the user doesn't see inaccurate information

justin :

this is the problem with vibe coding apps you did not even realize xcode has simulation of slow networks, hot phones, throttled gpu and much more — all built right in. To use. Before you submit to the app store.

quba :

Keeping you logged in before confirmation sounds like a security vulnerability, but I know nothing about webdev

MishaNyaIsTaken 1 :

I've literally sent your 26min YouTube optimization video for the 12$ server and made a skill out of it - thanks a lot for those skilled programmers for submissions, ive literally watched with my jaw dropped when heard some of those numbers (especially Fortran)

Franktek :

Also cache the user's session in the backend using Redis, use connection pooling, structure backend calls using async, throw in Gzip, page lists so that they load the first 25 items until some pages, and more.

LDNKS :

Why does he sound like Ben Shapiro 😂

MigratoryAtom79 :

Sava🇪🇺 :

Called api n+1 problem

Michael Butler :

Love your content mate

v12fiatmultipla :

Wouldn’t be better if you merge some of the requests? You can merge the xp, streak and maybe the first page of the leaderboard in a single API, and you can also merge session and subscription since a subscription could end during a valid session

Yeezus :

I would have just bought a 12$ dollar server

realenfield :

Cache

user5739179673719 :

Appreciate the break down. This is what gets learned from experience. local first is a great strategy, but then you have the hardest problem in computer science cache

Gazer Mar :

🔥 talk about excellence
