I love the way you explained the route handlers. I’ve watched many videos trying to explain what you did in 30+ minutes. I fully understand the process now. Thanks!

[@coderyan]

Happy to hear it helped!

I've been waiting so long for this video and my guy just uploaded, great job👍🏻❤️🐐

[@coderyan]

Thank you!

[@davidheimfert2816]

Thanks for all your videos! I started my first Next commercial project, thinking something like "I know React and CRA, so let's go for it". I quickly got stuck on APIs, and discovered your channel thanks to this video. I put the project on standby while I watched your entire playlist, which was very well explained in a simple way.

You’re welcome! Happy to hear the videos are helping and best of luck on your project!

Incredible as always 🔥 Thank You! 🚀

Would be great if this video had timestamps :)

whats the purpose of using useRouter instead of redirect(21:34) on the view post button? Whats the difference? can anyone explain?

[@volt4ge753]

a really useful guide, thanks
it would be better if you uploaded the final code to the git repo so that it can be quickly re-read without reviewing the video

[@coderyan]

Thank you and I appreciate the feedback. In future videos, I'm better about pushing the final code up to Github

[@SuperYoda7]

nicely explained. Even to me it made all sense. Just one question. Isn't it better to have the components directory outside of the app router ? since if we have it inside we would effectively create new routes ending up with localhost:3000/components/ or doesn't it make a difference as long as we don't define a route or page file ?

[@coderyan]

Thank you! And it doesn’t actually matter. The only time a folder becomes public is when you add a route.js or page.js file within the folder

[@SuperYoda7]

@@coderyan I see thanks, now I learned even more!

[@coderyan]

@SuperYoda7 happy to hear it!

[@HigherStudyAspirant]

Thanks for detailed explanation. but I have one confusion, what is the need of route handler when we can do the same thing from server components and client components.

[@coderyan]

Great question. And most of the time, you shouldn’t need to use a route handler. But there are situations where they’re useful. For example, if you update your database in a client component and want to revalidate the cache, you make make an API request to a route handler to revalidate the cache for a certain path

[@carlotubigon8763]

@Code Ryan Why is it needed to fetch it from route handlers first 24:04 before fetching it in posts page? Is it not possible to fetch it directly in posts page without the route handler?

[@coderyan]

Yeah that’s probably fine. But this video is covering route handlers so just showing how they work

[@carlotubigon8763]

@@coderyan I see, I just want to know when to use the route handlers and when to use in-page fetch. There may be some advantages/disadvantages between the two. Do you know any?

[@prashlovessamosa]

Thanks

[@coderyan]

You're welcome

[@Rotanakkosal]

I have an question? Since we can get data with fetch method, so why we need route hander ?

[@joseernestoroldan]

to create endpoints so you can create your own resources api.

[@stanleychukwu7424]

thank you boss! hi beautiful dog, you about to go for a walk!

[@coderyan]

Haha thank you!

[@mohanram18]

still don't understand the logic for not allow to create route.ts at the same route segment

[@coderyan]

I’m not entirely sure I understand what you mean, could you maybe rephrase your question?

[@mohanram18]

@@coderyan Nextjs uses the convention of page.tsx to serve a route, so the same way route handler has a convention of route.ts , page.tsx and route.ts can co-exist on the same level, But Nextjs does not allow at the same level.

[@muhammadparacha]

@@mohanram18 Yep, you're going to have to nest the route.ts in ./api/ or /app/api/...
