Prefix all the routes in Lumen - php

Question

Is there a way in Lumen to prefix all of my routes?
The thing is that I'm versioning my API via URI and for every group that I create I have to set the prefix to 'v1/*' like:
$app->group(['prefix' => 'v1/students/', 'namespace' => 'App\Http\Controllers\Students\Data'], function () use ($app) {
$app->get('/', 'StudentController#get');
$app->get('/{id}', 'StudentController#getByID');
});

Answer 1

Apparently, route groups in Lumen do not inherit any settings, which was intentional to keep the router simpler and faster (see comment here).
Your best bet will probably be to create a route group per version, in order to define a base prefix and controller namespace for that version. But, your individual routes inside those route groups will need to be slightly more verbose. Example shown below:
// creates v1/students, v1/students/{id}
$app->group(['prefix' => 'v1', 'namespace' => 'App\Http\Controllers'], function () use ($app) {
$app->get('students', 'Students\Data\StudentController#get');
$app->get('students/{id}', 'StudentController#getByID');
});
// creates v2/students, v2/students/{id}, v2/teachers, v2/teachers/{id}
$app->group(['prefix' => 'v2', 'namespace' => 'App\Http\Controllers'], function () use ($app) {
$app->get('students', 'Students\Data\StudentController#get');
$app->get('students/{id}', 'Students\Data\StudentController#getByID');
$app->get('teachers', 'Teachers\Data\TeacherController#get');
$app->get('teachers/{id}', 'Teachers\Data\TeacherController#getByID');
});

You could prefix all routes in your /bootstrap/app.php.
Currently, there should be something like
# may be slighlty different, since I typed this from memory
$app->router->group([
'namespace' => 'App\Http\Controllers',
], function ($router) {
require __DIR__ . '/../routes/web.php';
});
As you can see, this loads the web.php file and makes the $router variable available.
You can rewrite this to load any php file in the routes directory and prefix all those routes via
$app->router->group([
'namespace' => 'App\Http\Controllers',
], function ($router) {
// load all files in routes directory, prefix all of them
$globalPrefix = "/v1";
$router->group(["prefix" => $globalPrefix], function($router) {
$routes = glob(__DIR__ . '/../routes/*.php');
foreach ($routes as $route) require $route;
});
});
As you can see, all required routes are wrapped in $router->group with your application wide route prefix.
