Describe the elements of the MEAN stack

MEAN stack is just a collection of tech that work well together

  • Mongo
  • Express
  • Angular
  • Node.js

Set up static files

  1. mkdir public
  2. touch public/index.html
  3. mkdir public/js
  4. touch public/js/app.js

server.js:

app.use(express.static('public'));

public/index.html:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
    </head>
    <body>

    </body>
</html>

Set up Angular

  1. Include Angular
  2. Set up app
  3. Test {{}}

public/index.html:

<!DOCTYPE html>
<html ng-app>
    <head>
        <meta charset="utf-8">
        <title></title>
        <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js" charset="utf-8"></script>
    </head>
    <body>
        {{2+2}}
    </body>
</html>

Create App/Controller

public/js/app.js:

const app = angular.module('MyApp', []);

app.controller('MyController', function(){
    this.foo = 'bar';
});
  1. ng-app
  2. script tag for /js/app.js
  3. ng-controller
  4. {{ctrl.foo}}

public/index.html:

<!DOCTYPE html>
<html ng-app="MyApp">
    <head>
        <meta charset="utf-8">
        <title></title>
        <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js" charset="utf-8"></script>
        <script src="/js/app.js" charset="utf-8"></script>
    </head>
    <body ng-controller="MyController as ctrl">
        {{ctrl.foo}}
    </body>
</html>

Create new todo form

public/index.html:

<form>
    <input type="text" placeholder="description"/>
    Complete: <input type="checkbox"/>
    <input type="submit" value="Create New To Do Item"/>
</form>

Hook form up to controller properties

public/index.html:

<form>
    {{ctrl.description}} - {{ctrl.complete}}
    <input type="text" ng-model="ctrl.description" placeholder="description"/>
    Complete: <input type="checkbox" ng-model="ctrl.complete"/>
    <input type="submit" value="Create New Todo Item"/>
</form>

Make form make AJAX request on submit

public/js/app.js:

app.controller('MyController', ['$http', function($http){
    this.description = null;
    this.complete = false;

    this.createTodo = function(){
        $http({
            method:'POST',
            url: '/todos',
            data: {
                description: this.description,
                complete: this.complete
            }
        }).then(function(response){
            console.log(response);
        }, function(){
            console.log('error');
        });
    }
}]);

public/index.html

<form ng-submit="ctrl.createTodo()">
