API Response Caching
Example
public function index(Request $request) {
$key = "api:posts:" . md5(serialize($request->query()));
return Cache::remember($key, 300, function () use ($request) {
return PostResource::collection(Post::filter($request)->paginate(20));
});
}
// Invalidate on mutation
public function store(StorePostRequest $request) {
$post = Post::create($request->validated());
Cache::forget("api:posts:*"); // or use Cache::tags(["posts"])->flush();
return new PostResource($post);
} Pro Tip
Cache::remember(key, ttl, closure) is atomic — only one process recalculates on cache miss.
