🍿 Cache Expensive Runtime API Calls

Published 20 days ago • 2 min read

Hey Reader,

I’ve been heads-down the last few months, building something special 🤫.

It’s for every developer who’s ever felt like Next.js changes faster than they can keep up. Different caching rules. New folders. New ways to fetch data.

If that sounds familiar… this one’s for you.

Next week, I’m dropping something big, something that’ll help you finally understand how all the new pieces in Next.js 16 fit together.

No hype, no fluff - just the clarity you’ve been looking for.

Make sure you keep an eye on your inbox, you’ll get early access before anyone else 😉.

🍿 Weekly Snack: Cache Expensive Runtime API calls

Just a reminder, "use-cache" is a Next.js 16 feature lets you mark a component, function or a Page as cacheable.

If your component becomes dynamic because you called connection(), cookies(), or headers()… regular "use cache" won't work i.e. you won't be able to cache your API call even though it is expensive.

You need to use "use cache: remote" instead when you are caching in a Dynamic Context.

Now, There is more to caching though in Next.js.

There are 3 flavours of caching.

→ use cache: allows you to mark a route, React component, or a function as cacheable
​→ use cache: private: allows you to use runtime APIs like cookies, headers, or search params and cache them
​→ use cache: remote: enables caching of shared data in dynamic contexts (just covered)

You can read what "use cache: private" does here and "use cache" does here.​
