Creating Single Page Web Application using AngularJS | Hire AngularJs Developer - Agira Technologies A single page web application, as the name suggests, is a web application that fits itself on to a single web page with the goal of providing its users an experience similar to that of desktop applications. There are two ways it can work. Either all the necessary code- HTML, JS, and CSS- is retrieved by just loading a single page or the required resources are loaded dynamically and added to the page as and when necessary, in response to user actions. Advantages of creating SPA The whole page need not be refreshed- Only the part of the web page that has to be changed has to be loaded.Provides the user better experience- The web pages are extremely fast and responsive.Allows us to work offline- Even if the user loses internet connectivity, he can still continue working because all the pages are already loaded in a SPA. Disadvantages of SPA Open source JavaScript frameworks that help in building SPAs include: AngularReactEmberAureliajsjsBackbone $scope.Title = "Single Page Application (SPA)";
Accueil | The Hacking Project nodejs-introduction Asynchronous programming Node.js is entirely asynchronous consider this analogy... You go down to a fast food joint and order a cheeseburger, they will immediately take your order and then make you wait around until the cheeseburger is ready. In the meantime they can take other orders and start cooking cheeseburgers for other people. Imagine if you had to wait at the register for your cheeseburger, blocking all other people in line from ordering while they cooked your burger! Node.js is entirely asynchronous You have to think differently What's the output? echo 'Hello'; sleep(2); echo ' world Node.js setTimeout(function () { console.log(' world.') }, 2000) console.log(' Hello'); Node.js is entirely asynchronous You have to think differently Failure to understand the event loop and I/O based model could lead to anti-patterns (bad code) Node uses an event-loop to perform non-blocking and asynchronous I/O consider this jQuery code... $.post('/resource.json', function (data) { console.log(data) });

La refactorisation – De geek à directeur technique La refactorisation est un exercice qui devrait être maîtrisé par tous les développeurs, encadré par tous les chefs de projets et encouragé par tous les directeurs techniques. Le refactoring, qu’est-ce que c’est ? Derrière cet affreux anglicisme se cache le fait de réécrire du code qui a déjà été développé. Le but n’est donc pas d’ajouter de nouvelles fonctionnalités, mais plutôt d’assurer un suivi de l’existant, de faire un ménage qui en facilitera la maintenance. Nous nous sommes tous retrouvés un jour ou l’autre devant des bouts de code sans queue ni tête, manifestement écrits à la va-vite, ne respectant aucune norme, avec une documentation périmée, sans commentaire, ou truffés de code mort. Mais la bonne attitude, c’est d’organiser l’amélioration de ce code. Je vais faire un parallèle avec la construction immobilière. Comment s’y prendre On peut découper un refactoring en 4 étapes précises. Élimination du code mort. Quand faire une refactorisation C’est la grande question habituelle.
