Optimize Queries with Eager Loading

Reduce the number of database queries by using Eager Loading. Eager Loading helps you load related models in a single query, avoiding the N+1 query problem, thus improving performance and efficiency.

Without Eager Loading (N+1 problem)

$posts = Post::all();
foreach ($posts as $post) {
    echo $post->author->name;
}

With Eager Loading.

$posts = Post::with('author')->get();
foreach ($posts as $post) {
    echo $post->author->name;
}
