Nice design 👍

Hi Arif, nice video. What tool did you use for illustrating the operation flow.

Closed all the VPSs and moved to Cloudflare, life's easy.

Subbed bro

6 USD per month for those specs are crazy expensive. I pay 11 USD per YEAR for the same!

Try insomnia

This is really cool! I was recently debating between paying for a VPS or an edge function service, and did some research on what I could get for ~5$. Then I realized that I was forgetting about RAM limitations on a VPS! If I'm only deploying one project, that's fine, but over time you'll probably end up deploying several hobby projects. Eventually, you would need to upgrade the VPS even if you have 0 users, in order to host the extra apps, which kinda sucks. However... With edge functions, the number of projects doesn't matter, only the requests does! Cloudflare Workers was the cheapest with 10 million requests/month for just $5. It might be less than the number of requests the VPS could do, but I can host unlimited projects here. So my reasoning was to just use Cloudflare Workers, and if I ever reached the 10 million requests/month, then it means my app is popular and I probably made a good amount of money! And I can just use that money to switch to an expensive VPS just for that popular app.

thanks bro, you are the best!

Nice tool

how to do process payment from bangladesh

from bangladesh we can't use stripe for our saas. then what?

is docker hub safe, or anyone can access those images

Please do at 200 or 300 and share the stats of the system How do cpu and ram perform?

Insightful

It was cool to see a load test and learn about this library, I've never ran a load test before. Thanks for sharing.

It also depends on the code you have written. Gzip, reddis, etc

you're paying too much i think, hostinger offers are way better

can you share where you got your excalidraw icon library please?

Response time is absolutely trash bro.

nice one

damn, cool library. i want this style in my blog

why not host static site on netlify or something for free?

Hi, this was a pretty helpful to me, but how can we test a page which waits for more than 3 & 4 apis response for the complete page load, then how can we test that page response time for a set of users?

can you share how much time it took you to get here?

You need more likes my man Keep the good work I'm sure you will be a beast here

Great content. Please do a tutorial on load testing

Ty for your tests, subscribed 🫡

Thanks for the video mate, looking for more content from your channel

Can you please do a similar video to show the difference between CPU and GPU? I mean at what point does CPU become unfeasible & we ought to go with a GPU?

Great content @Arif, Learned a lot. Please create more lessons like this.

I need more of this type of content, subscribed

Thanks that's helpful

Can I know the note/sketch app that you are using to draw mind map? and can you recommend one for making psudeo app code?

Very foundational, easy to follow and informative video, thanks! Curious question: the site seems to be a doc site, which could be a static site, what are you using sqlite database for?

This is so handy was just checking out how much workload I could put on the 6$ vps today

Looking good

If it's possible, can you share the repo to be able to see how this is was configured?

I think you did a great job but you used the wrong example. most people here really didn't think outside the scope, they practically evaluating your explanations and methods using your example which actually will well be inefficient and over-complicating the solution Race conditions is practically one of the major issues high traffic companies that do a lot of write than read on the database faces... While many database itself has been optimizing thier efficiency to prevent race conditions you still want to do well to handle such situations on the backend If your audience are JavaScript devs i don't expect them to know much 😅😅😅 peace out 😉

In real life scenario for this types of system people should use queue like rabbitqm and database transaction if the payment api directly connected with local banking system. But if they use stripe for payment handling stripe will handle most of work.

Great job. I like this type of load testing.

Loved this vid! Subbed, keep up the great work

I dont think this would work if your application is horizontally scaling. Like if you have more than one instance to handle this load

It can be done using transactions on database, like using cheking number of titkets and insert and decrement ticket count, the another user at same time get rollbacked if the ticket count is 0

this can simply be handled using uid's and mapping it w the ticket entitity itself where one ticket can have only one user! i don't think you need to explicitly track every single promise in the codebase tho, ig it's a good practice or you're overdoing it :D

This can be solved by using database transaction. you don’t need any extra logic to handle race condition

I love to contribute
