A fast, flexible router which can be used to quickly build RESTful web apps.

composer require bayfrontmedia/route-it
Default options:
use Bayfront\RouteIt\Router;
$options = [
'automapping_enabled' => false,
'automapping_namespace' => '',
'automapping_route_prefix' => '',
'class_namespace' => '',
'files_root_path' => '',
'force_lowercase_url' => false
];
$router = new Router($options);
When force_lowercase_url is enabled in the $options array, all incoming requests which contain uppercase characters will be redirected via a 301 redirect to their lowercase counterpart.
Query parameters will not be affected.
When automapping is enabled, Route It will automatically attempt to dispatch the incoming request in the form of class/method/optional-parameter without having to define each individual route.
The incoming request must match the automapping route prefix, and classes must exist in the automapping namespace as defined in the $options array.
For example:
use Bayfront\RouteIt\Router;
$options = [
'automapping_enabled' => true,
'automapping_namespace' => 'App\\Pages',
'automapping_route_prefix' => '/app'
];
$router = new Router($options);
Using the above example, incoming requests would be automapped like so:
| Endpoint | Class | Method | Parameter |
|---|---|---|---|
/app |
App\Pages\Home | index | |
/app/customers |
App\Pages\Customers | index | |
/app/customers/edit |
App\Pages\Customers | edit | |
/app/customers/edit/5 |
App\Pages\Customers | edit | ['id' => 5] |
Understandably, automapping does not provide a solution for every scenario, in which case, routes can be added.
Named routes are helpful when using hyperlinks in controllers, views or templates. By referencing a named route instead of a specific URL, the hyperlink will stay up-to-date with your defined routes.
When dispatching a request using the dispatch , dispatchTo, or dispatchToFallback methods,
Route It will automatically insert an array of all named routes to the destination as a parameter with the key of routes,
unless otherwise specified.
See documentation for these methods for more information.
Wildcards can be used when defining a route in order to dynamically define a path, and send its value to the destination as a parameter. The syntax is {type:name}, where type is the wildcard type, and name is the name of the parameter which is to be passed to the destination.
Wildcards include:
*: Any non-whitespace character in this segment of the requestalpha: Any alphabetic characters in this segment of the request (see ctype_alpha)num: Any numeric characters in this segment of the request (see ctype_digit)alphanum: Any alphanumeric characters in this segment of the request (see ctype_alnum)**: Everything else that may exist on the request path (catch-all)?: Optionally existing in this segment of the request (can only be used at the last segment)

Description:
Adds a defined route. Wildcards can be used in the path.
Destinations can be a callable function, a named route, a file, or a $class->method().
Each route can have its own predefined parameter(s), and parameters can also be defined dynamically by a "wildcard".
Parameters:
$methods(string|array): Request method(s) for which this route is valid, or "ANY"$path(string): Request path$destination(mixed)$params = [](array): Parameters to pass to the destination$name = NULL(string|null): An optional name to assign to this route
NOTE: Names should not be assigned to routes which include wildcards in the path. Named routes are only intended to define specific URL's. Named route names must be unique, as names which already exist are overwritten.
Returns:
- (self)
Example:
$router
// Callable
->addRoute('GET', '/customers', function () {
echo 'Customers';
})
// Callable with a wildcard parameter
->addRoute('GET', '/customers/{num:id}', function ($params) {
echo 'Customer id: ' . $params['id'];
})
// Callable with optional wildcard (if existing in the request path, it will overwrite the defined parameter)
->addRoute('GET', '/optional/{?:name}', function ($params) {
echo 'Hello, ' . $params['name'] . '! This is a callable with an optional parameter.';
}, [
'name' => 'John'
])
// Callable, saving as a named route
->addRoute('GET', '/login', function($params) {
