One of the cornerstones of developing a Symfony application is working with routes. The routing infrastructure ensures that we can use readable URLs (for example, /products/hammer instead of index.php?page=products&productid=12345) and that these URLs are mapped to a controller in our application that can respond to requests.
The Symfony Plugin provides several facilities for working with routes.
Code completion for routes
IntelliJ IDEA provides code completion for functions that take a route name as an argument. In the editor, press Ctrl+Space to invoke code completion and do any of the following:
Specify arguments for such controller functions as
Specify arguments for such Twig functions as
Navigation for routes
Since routes are linked to a controller, you can use Navigate to declaration Ctrl+B on a route to navigate to the corresponding controller. Alternatively, Ctrl+Click the service's name.
To navigate back to a route mapped to a controller, click the route icon in the editor gutter.
Missing route inspection
Whenever you use the name of a route that is not defined or misspelled, IntelliJ IDEA displays the corresponding warning from the Missing Route inspection. .
