JavaScript : organiser son code en modules

JavaScript a été initialement conçu pour être un langage facile à prendre en main. Néanmoins, avec l'augmentation importante des volumes de code utilisés sur Internet, on se heurte désormais comme dans la plupart des langages de programmation aux problèmes inhérents à la cohabitation de plusieurs bibliothèques. L'objectif de cet article est de présenter quelques techniques permettant de rendre vos bibliothèques plus faciles à maintenir, plus lisibles et mieux structurées en les organisant sous forme de modules, minimisant ainsi les risques d'interaction involontaire avec l'extérieur.

Composition is one of the reasons we regularly talk about React “Components”, “Ember.Component”s, Angular directives, Polymer elements and of course, straight-up Web Components. We may argue about the frameworks and libraries surrounding these different flavours of component, but not that composition is inherently a bad thing. Note: earlier players in the JS framework game (Dojo, YUI, ExtJS) touted composition strongly and it’s been around forever but it’s taken us a while for most people to grok the true power of this model as broadly on the front-end. Composition is one solution to the problem of application complexity. Now, the way that languages in the web platform evolve are in direct response to the pain caused by such complexity. Complexity on its own can take lots of forms, but when we look at the landscape of how developers have been building for the web over the last few years, common patterns can be one the most obvious things worth considering baking in solutions for. 1.

As example of its capabilities, the File API could be used to create a thumbnail preview of images as they're being sent to the server, or allow an app to save a file reference while the user is offline.

Additionally, you could use client-side logic to verify an upload's mimetype matches its file extension or restrict the size of an upload. The spec provides several interfaces for accessing files from a 'local' filesystem: File - an individual file; provides readonly information such as name, file size, mimetype, and a reference to the file handle.
