In Laravel 8, there are some conventions that are widely accepted for naming APIs. Following these conventions can make your code more maintainable and easier to understand for other developers. Here are some of the best naming conventions for APIs in Laravel 8:
Route Names
For route names, it is recommended to use a verb followed by a noun. This approach is simple, yet effective, because it accurately describes what each route does. It also makes it easy to generate URLs for each route. For example, GET /users
would have a route name of users.index
. Here are some examples:
-
GET /users
=>users.index
-
GET /users/create
=>users.create
it is used to show a form that allows to create a new user. -
POST /users
=>users.store
-
GET /users/{id}
=>users.show
-
GET /users/{id}/edit
=>users.edit
-
PUT/PATCH /users/{id}
=>users.update
-
DELETE /users/{id}
=>users.destroy
It is also a good practice to group related routes using route prefixes. This technique can help you organize your routes and make them easier to read. For example, you might group all of your user-related routes under a /users
prefix:
Route::prefix('users')->group(function () {
Route::get('/', 'UsersController@index')->name('users.index');
Route::get('/create', 'UsersController@create')->name('users.create');
Route::post('/', 'UsersController@store')->name('users.store');
Route::get('/{id}', 'UsersController@show')->name('users.show');
Route::get('/{id}/edit', 'UsersController@edit')->name('users.edit');
Route::put('/{id}', 'UsersController@update')->name('users.update');
Route::delete('/{id}', 'UsersController@destroy')->name('users.destroy');
});
Controller Names
For controller names, it is recommended to use a plural noun followed by the Controller
suffix. This approach is consistent with the idea of using plural nouns for resources, and it accurately describes what each controller does. For example, a controller for managing users would be named UsersController
. Here are some examples:
UsersController
PostsController
CommentsController
TagsController
CategoriesController
Model Names
For model names, it is recommended to use a singular noun. This approach accurately reflects the fact that each model represents a single entity in your application. It also makes it easy to generate model instances. For example, a model for managing users would be named User
. Here are some examples:
User
Post
Comment
Tag
Category
Resource Names
For resource names, it is recommended to use a plural noun. This approach makes it easy to understand that each resource represents a collection of entities, rather than a single entity. It also makes it easy to generate URLs for each resource. For example, a resource for managing users would be named Users
. Here are some examples:
Users
Posts
Comments
Tags
Categories
Database Table Names
For database table names, it is recommended to use a plural noun. This approach is consistent with the idea of using plural nouns for resources. It also makes it easy to understand that each table represents a collection of entities, rather than a single entity. For example, a table for managing users would be named users
. Here are some examples:
users
posts
comments
tags
categories
API Versioning
Versioning your API is important to ensure that changes do not break existing clients. There are various ways to version your API, but one popular method is to use version numbers in your URLs. For example, /v1/users
would be the URL for version 1 of the users API. Here are some examples:
/v1/users
/v2/users
/v1/posts
/v2/posts
Another approach to API versioning is to use custom HTTP headers. This approach can be useful when you do not want to modify your URLs. For example, you might use a custom X-Api-Version
header to specify the API version:
GET /users HTTP/1.1
Host: example.com
X-Api-Version: 1
HTTP Response Codes
HTTP response codes are an important part of any API. They provide information about the result of the request and help clients understand what happened. Here are some common HTTP response codes and what they mean:
-
200 OK
- The request succeeded. -
201 Created
- The request succeeded and a new resource was created. -
204 No Content
- The request succeeded, but there is no response body to return. -
400 Bad Request
- The request was malformed or invalid. -
401 Unauthorized
- The request requires authentication. -
403 Forbidden
- The authenticated user does not have access to the requested resource. -
404 Not Found
- The requested resource does not exist. -
422 Unprocessable Entity
- The request was well-formed, but was unable to be followed due to semantic errors. -
500 Internal Server Error
- A generic error occurred on the server.
Pagination
If you are returning a large number of resources, it is important to paginate your results. Pagination allows clients to retrieve resources in smaller, more manageable chunks. Laravel provides built-in support for pagination, making it easy to implement in your APIs. Here are some examples of how to paginate your results:
GET /users?page=1&per_page=10
GET /posts?page=2&per_page=5
Authentication
Authentication is an important part of any API. It allows you to restrict access to certain resources and ensure that only authorized clients can access your API. Laravel provides built-in support for various authentication mechanisms, such as API tokens and OAuth2. Here are some examples of how to use these mechanisms:
API Tokens
API tokens are a simple way to authenticate clients. Each client is issued a unique token that they use to authenticate their requests. Laravel provides built-in support for API tokens, making it easy to implement in your APIs. Here are some examples of how to use API tokens:
// Generate a new token for the user
$token = $user->createToken('token-name')->plainTextToken;
// Authenticate a request using the token
$response = $client->get('/api/user', [
'headers' => [
'Authorization' => 'Bearer ' . $token,
'Accept' => 'application/json',
],
]);
OAuth2
OAuth2 is a more complex mechanism for authenticating clients. It involves a series of redirects and exchanges of tokens between the client and the server. Laravel provides built-in support for OAuth2, making it easy to implement in your APIs. Here are some examples of how to use OAuth2:
// Generate an authorization URL for the client
$url = $provider->getAuthorizationUrl();
// Redirect the client to the authorization URL
return redirect($url);
// Handle the callback from the provider
$token = $provider->getAccessToken('authorization_code', [
'code' => $request->code,
]);
// Authenticate a request using the access token
$response = $client->get('/api/user', [
'headers' => [
'Authorization' => 'Bearer ' . $token->getToken(),
'Accept' => 'application/json',
],
]);
Error Handling
Error handling is an important part of any API. It allows you to provide meaningful error messages to clients when something goes wrong. Laravel provides built-in support for error handling, making it easy to implement in your APIs. Here are some examples of how to handle errors in your APIs:
// Throw an exception when a resource is not found
if (!$user) {
throw new NotFoundHttpException('User not found.');
}
// Return a JSON response when a validation error occurs
if ($validator->fails()) {
return response()->json([
'message' => 'The given data was invalid.',
'errors' => $validator->errors(),
], 422);
}
// Return a JSON response when an unexpected error occurs
if ($exception instanceof Exception) {
return response()->json([
'message' => 'An unexpected error occurred.',
], 500);
}

Hello
I think you're wrong for
GET /users/create => users.create
. GET can't create things but just return records.POST /users
is for the creationPUT /users
is for updating the entire records (you need to pass all the fields)PATCH /users
is for updating just a few fields of the records (you just need to pass these fields; not all)Hello Christophe Avonture.
You are correct but I mean with
GET /users/create => users.create
, is to get the view that contains the form for submitting the new users.Thanks for your comment, I am going to make a modification to better clarify the route names part.
