Javascript continue de faire des adeptes ! Apr\u00e8s que d’autres aient essay\u00e9 de mettre du XML, ou des triplets (ou du rdf, i.e. des triplets xml) dans une bd, des membres de la fondation Apache ont essay\u00e9 de mettre des objets javascripts dans une BD (JSON): CouchDB. Et pourquoi pas aussi du code et du html ? le tout pour faire une application web, si c’est possible: CouchApp. Au final, on obtient donc une environnement NoSQL permettant le d\u00e9veloppement d’application web standard (client leger + bd) avec comme seul langage de programmation n\u00e9cessaire le javascript (ni php, ni ruby, ni …). Le tout accessible, \u00e0 partir d’un navigateur web et expos\u00e9 \u00e0 tous les utilisateurs (open de bout en bout, de la pr\u00e9sentation, au code m\u00e9tier, jusqu’aux donn\u00e9es !)<\/p>\n

Seulement du javascript ? oui, enfin, c’est un peu vite dit, dans la version propos\u00e9 initialement, c’est du javascript+jquery+evently+mustache+prototype. Mais bon, pour les puristes, on peut enlever le jquery+evently+mustache+prototype (il faut mesurer ce que cela apporte et ce que cela coute ! depuis que j’utilise javascript, j’ai eu le temps de voir arriver\/passer : prototype, script.aculo.us, dojo, rico, ext, yui, mootools, mochikit, qooxdoo, jquery, node, underscore, evently, mustache, vanilla, commonJS, … sachant que les navigateurs sont de plus en plus conformes \u00e0 la norme javascript.).<\/p>\n

Enfin, bref, le temps de mettre au point quelques lignes (euh, disons un petit mois, mais seulement dans mes moments libres, ce qui limite pas mal le temps de travail effectif, mais permet de maturer et de mesurer la motivation), et voila une premi\u00e8re appli (compte guest, mot de passe guest) chez un h\u00e9bergeur “gratuit” (ce qui explique les n\u00e9cessit\u00e9s de login\/mdp ?) : https:\/\/denisb.couchappy.com\/mem\/_design\/mem\/index.html<\/a><\/p>\n

Avec la bd au m\u00eame endroit que le html\/code, il n’y a plus de probl\u00e8me de “same origine policy”, mais il reste \u00e0 voir comment la gestion de la s\u00e9curit\u00e9 peut s’effectuer et si l’on arrive \u00e0 partager le code\/donn\u00e9es facilement (m\u00eame \u00e0 l’int\u00e9rieur du cadre “CouchDB\/CouchApp”).<\/p>\n","protected":false},"excerpt":{"rendered":"
