We’ve all had this error, and it’s pretty annoying, to say the least. It always seems we’ve done everything right and once we try to render the page, the almighty Route Not Defined error is produced.

It usually looks like the screenshot below –

Checklist

When you come across this error in Laravel, make sure to check the following parts of your application

1. Web.php

Ensure that the route you are trying to render has had a proper route setup in this file. The route must be named and therefore, should look like the following –

Route::get('/dashboard', 'MyController@dashboard')->name('dashboard');

Notice the ->name('dashboard') part of this routes syntax, this is of extreme importance to be correctly defined if you want to use the route() function to generate URLs.

2. View or Controller files

Lastly, you must ensure that the route function parameter matches the name exactly as defined in the web.php file. For example,

In a view

Dashboard

In a controller

$url = route('dashboard');
