[20:44, 1/18/2018] +254 704 407117: then after creating the project cd in to its folder cd passport
install laravel

composer create-project --prefer-dist laravel/laravel passport

so, create a db, I named mine gtt_api,
then edit .env in root folder like this, the DB part

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=gtt_api
DB_USERNAME=root
DB_PASSWORD=

use your credentials

I realised kama yangu new project haina .env, incase youre like me, create a .env file and copy the .env.example to it,
incase this affetcs you,
run 
php artisan key:generate

run php artisan make:auth

run php artisan serve 
the open
http://localhost:8000/
 youll see the login and register links, tuko hapo
 
ok so in the database folder,  database/migrations
kuna create users table< thats what will run our users table ,migration, for now, we wont edit it,
we'll just use email, name and passsworsd

so run
php artisan migrate 
to create the tables

SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was t  
  oo long; max key length is 767 bytes (SQL: alter table `users` add unique `  
  users_email_unique`(`email`)) 

incase you get this error, for those using maria DB, its because of the db encoding stuff,

you can correct it by changing your AppServiceProvide.php
check the gist, for now we will 
ignore it, it wont affect us


 ok, I forgot something, 
so run this command, we want to add the api_token column

php artisan make:migration add_api_key_to_users --table=users

continue 1

then run 
php artisan migrate 

again

continue 3

http://localhost:8000/api/login while wmpty
returns

{
    "success": false,
    "message": {
        "remember": [
            "The remember field is required."
        ]
    }
}

        "api_token": "xlWZudhvKeck3HCrpkixTps8xTgr66IPWoIVLXihWINnK1adsjXeBtyMB6x9"
    }
}

continue 4

lets create logout function in LoginController.php

add the function below the login function
logout function

public function logout(Request $request)
    {
    	//pass request in header

	    $user = Auth::guard('api')->user();

	    if ($user) {
	        $user->api_token = null;
	        $user->save();

	        return response()->json([
		    	'success' => true,
		    	'message' => 'User logged out.'], 200);
	    }

	    return response()->json([
	    	'success' => false,
	    	'message' => 'User Not loged in'], 200);
	}
  

final routes

Route::middleware(['auth:api'])->group(function () {
	    Route::post('logout', 'API\LoginController@logout');
	});

Route::post('login', 'API\LoginController@login');
Route::post('register', 'API\RegisterController@register');


lets do register now
create a controller 
php artisan make:controller API/RegisterController

Add too routes these

continue2

tuko sawa?, kama huna error, its, ok
if you have the error
now dlete the tables kwa db, the
reu
php artisan migrate

no errors sasa

now, in root folder
check for /routes/api.php

Route::post('login', 'API\LoginController@login');

run 
php artisan make:controller API/LoginController

navigate to
App\Http\Controllers\API, you'll find the controller<
then we need to add a function login


run php arisan route:list

you should see this route

 | POST     | api/login              |                  | App\Http\Controllers\API\LoginController@login                         | api
