How To Fix NextJS 13’s N+1 Problem
If you’re using NextJS 13 and you’re experiencing the N+1 problem, don’t worry! There are a few steps you can take to fix it and improve the performance of your application.
What is the N+1 Problem?
The N+1 problem occurs when a database query is executed multiple times within a loop or a recursive function, resulting in a large number of unnecessary database calls. This can significantly slow down the performance of your application and cause it to become unresponsive.
How to Fix It
Here are a few steps you can take to fix the N+1 problem in NextJS 13:
- Use Data Loaders
- Optimize Your Queries
- Use Pagination
One of the best ways to fix the N+1 problem is to use data loaders. Data loaders allow you to batch and cache database queries, reducing the number of unnecessary calls and improving the efficiency of your application.
Another way to fix the N+1 problem is to optimize your database queries. Look for opportunities to combine related queries, use indexes, and limit the number of rows returned to reduce the overall load on your database.
If you’re working with large datasets, consider implementing pagination to limit the number of items returned in each query. This can help reduce the impact of the N+1 problem and improve the performance of your application.
Conclusion
By following these steps, you can fix the N+1 problem in NextJS 13 and improve the performance of your application. Remember to use data loaders, optimize your queries, and consider implementing pagination to reduce the impact of unnecessary database calls. With these changes, you can ensure that your NextJS 13 application is running efficiently and responsively.
I have question about caching. All the requests are made to phones with different identifiers so what is cached here? Doesn't caching make sense when you are making say several requests to phone with same ID?
Couldn’t you just move the code that you put in your endpoint into the very first server component?
This is what I have been doing with a lot of my data fetching in next 13. I typically have a server component for the page, do my data fetching there, and then pass that data into other server components, or client components as needed.
Do you have any totorial for nodejs with typescript?
this is by far very useful content. you're making us a great developer just like you Jack! you're awesome!
What theme do you use?
25:55 blew my mind. Really appreciate this video. Keep it up with such examples. Love the "Don't do" section. I think we need more of these
what's that terminal theme?
Omg, react server components can quickly become a footgun. People say that this is a step towards PHP and i don't know how to feel about that, but I feel like we'll have to create a new category of FE dev due to the tight couppling with backend with react server components. Maybe, It's a good thing from full stack dev's perspective, but for me, as a front end dev, just seems wrong hahahaha.
Thanks for so much Jack. Excellent video. Perfect for improving preformance. When you can make some video about render types for Nextjs, please!

okay awesome demo but with next 13 and server components things look more confusing and wrong paths opening up -_-
Basically this is applying the Fundamental theorem of Software Engineering. The "aggregate" is nothing less than a glorified cache. Still really good info.
One thing I like about these meta frameworks is how easy it is to add this "extra level of indirection" by having a backend for frontend.
An awesome video that was well worth the watch. Thank you for exploring this tech early and explaining to the rest of us!
Just being honest here… it is a little sad that you have to even teach this considering the fact that if you did this same process in vanilla javascript you wouldn't even run into this problem… things like React and Next were supposed to make front developers into actual programmers! But all they actually did was make EVERYTHING more complicated.
What for theme you use in your youtube videos?
Do you have a video of your vscode setup by any chance?
Great video as usual! I do feel some of this might be a little deceptive, by generating all the iPhones up front in the backend for frontend you essentially turned the API requests into something like what a static site generator would do. This works nice for this static API but if the API needs to be fetched with user data that approach wouldn't work well
Great work
who would be bored with pokemon examples they were great
Hey Jack,
It would have been nice to do one more example with request batching, basically what dataloaders do. They are most used with graphql where the resolvers exhibit the same N+1 problem as RSCs.
That way we keep the data fetching in the components but while only a single request is actually made to the API.
Another topic I would have liked you to tackle is component streaming: making a single big request might actually make the page load feel slower because no individual Card component can start streaming to the client before the request is done.
I believe that a slightly longer total page load but where it is progressively streamed to the client is preferable to aggregating everything in a request.
