angular material with express web app personal project

para que no nos pida los credenciales a cada git push

git config remote.origin.url https://{{username}}:{{password}}@github.com/{{username}}/{{repository name}}

En express podemos hacer que un param:

/api/thumbnails/:parametro

sea opcional añadiendo un ? al final del parametro

/api/thumbnails/:parametro?

Las querys son

/api/thumbnails?busqueda=ejemplo

y en express se guardan en:

req.query.busqueda

Colocar un minimo de 3 console.logs describiendo el proceso que deberia ocurrir en el caso de que funcionase correctamente

ej:

console.log('Aqui deberia ejecutarse la function');
console.log('Aqui deberia recibirse el data del find()');

Para usar passport estoy siguiendo el tutorial del libro mean web development sobre passport paso por paso.

There are three main parts in using passport.js:

1. Requiring the module and using its passport.initialize() and passport.session() middleware with express.
2. Configuring passport with at least one Strategy and setting up passport's serializeUser and deserializeUser methods.
3. Specifying a route which uses the passport.authenticate middleware to actually authenticate a user.

serializeUser se encargar de decidir que información guardar en la sesión, se guardará en:

  req.session.passport.user = { // our serialised user object // }.

The result is also attached to the request as req.user.

Entonces después se llamará a la request.

SUBSEQUENT AUTHENTICATED REQUESTS FLOW

On subsequent request, the following occurs:

1. Express loads the session data and attaches it to the req. As passport stores the serialised user in the session, the serialised user object can be found at req.session.passport.user.
2. The general passport middleware we setup (passport.initialize) is invoked on the request, it finds the passport.user attached to the session. If is doesn't (user is not yet authenticated) it creates it like req.passport.user = {}.
3. Next, passport.session is invoked. This middleware is a Passport Strategy invoked on every request. If it finds a serialised user object in the session, it will consider this request authenticated.
4. The passport.session middleware calls passport.deserializeUser we've setup. Attaching the loaded user object to the request as req.user.

SUMMARY PASSPORT METHODS AND MIDDLEWARE

• passport.initialize middleware is invoked on every request. It ensures the session contains a passport.user object, which may be empty.
• passport.session middleware is a Passport Strategy which will load the user object onto req.user if a serialised user object was found in the server.
• passport.deserializeUser is invoked on every request by passport.session. It enables us to load additional user information on every request. This user object is attached to the request as req.user making it accessible in our request handling.
• Our Local Strategy is only invoked on the route which uses the passport.authenticate middleware.
• Only during this authentication passport.serializeUser is invoked allowing us the specify what user information should be stored in the session.
• OVERVIEW PASSPORT METHODS ATTACHED TO THE REQUEST

• req.login()
• req.logout()
• req.isAuthenticated()
• req.isUnAuthenticated()

Una función asignada or pasada como un argument.

var yo = function(){} //<-- callback function

yo(function(){}) //<-- callback function

That is what we call a callback.

Cuando un callback se ejecuta sometime in the future osea que es asincrono, esto quiere decir que el código nunca se ejecutará mientras el síncrono, osea el código principal, esté en funcionamiento, esto es debido a que javascript es singlethread.

Por ello ejecutará los callbacks uno por uno tras el código síncrono principal

Los callback se crean síncronomicamente pero ejecutados asíncronicamente.

  'use strict';

  app.directive('ngEnter', function () {
    return function (scope, element, attrs) {
      element.bind('keydown keypress', function (event) {
        if(event.which === 13) {
          scope.$apply(function (){
              scope.$eval(attrs.ngEnter || attrs.ngClick, {$event:event});
            });
          event.preventDefault();
        }
      });
    };
  });
