Best Way to Organize Routes Specially the API route

One way to go about it is to create a small helper function.

The you could do something like this.

<?php
  routesForModel('books');
  routesForModel('games');
  routesForModel('movies');
  routesForModel('records');
  routesForModel('profiles');

In the Models/books.php

Route::get('/books', BooksIndexController::class)->name('books.index');
Route::get('/books/create', BooksCreateController::class)->name('books.create');
Route::get('/books/{bookShowView}', BooksShowController::class)->name('books.show');
Route::post('/books/store', BooksStoreController::class)->name('books.store');
Route::get('/books/edit/{bookShowView}', BooksEditController::class)->name('books.edit');
Route::put('/books/{book}', BooksUpdateController::class)->name('books.update');
Route::delete('/books/{book}', BooksDeleteController::class)->name('books.delete');

And the helper function

function routesForModel($model)
{
    return require base_path("routes/Models/{$model}.php");
}
