on connait l’importance d’avoir des sites qui r\u00e9pondent vite<\/a>…<\/p>\nComment en est on arriv\u00e9 l\u00e0 ?<\/p>\n
En fait, c’est une d\u00e9rive, largement encourag\u00e9e par pas mal de boites du secteur.<\/p>\n
Je m’explique.<\/p>\n
Pour la plupart des entreprises, la partie technique du site e-commerce est un centre de cout, pas un centre d’investissement (dommage \ud83d\ude09 ).<\/p>\n
Dans un tel contexte, l’ajout de fonctions au site est toujours une n\u00e9gociation difficile.<\/p>\n
La parade ? Le Javascript !<\/p>\n
Les boites viennent vous voir, et vous explique que leur solution est \u00ab\u00a0non intrusive\u00a0\u00bb, et qu’il suffit d’ajouter \u00ab\u00a0un petit script de rien du tout\u00a0\u00bb.<\/p>\n
Et \u00e7a marche ! En quelques heures, le site a int\u00e9gr\u00e9 une nouvelle fonction, et cela n’a presque rien cout\u00e9 en int\u00e9gration…<\/p>\n
Mais voil\u00e0, tout cela \u00e0 un prix : le \u00ab\u00a0petit code javascript\u00a0\u00bb inclus un autre fichier, bien plus gros, qui lui m\u00eame fait appel \u00e0 des fonctions externes… et la page a pris 20, 30% de temps de chargement en plus, sans compter les bugs \u00ab\u00a0qui viennent avec\u00a0\u00bb parce que certaines fonctions sont incompatibles, les unes avec les autres.<\/p>\n
Tout cela se corrigera avec le temps, quand la qualit\u00e9 deviendra un crit\u00e8re de performance (ce qu’il est vraiment !).<\/p>\n
La qualit\u00e9, cela doit aller jusqu’au bout, jusqu’au contenu qu’on envoie sur le poste du client.<\/p>\n
Le pire, c’est qu’il n’est pas tr\u00e8s compliqu\u00e9 de faire le m\u00e9nage l\u00e0 dedans : compiler<\/del>\u00a0regrouper les fichier javascript, supprimer les fonctions inutiles, compresser tout \u00e7a… Et gagner de pr\u00e9cieuses secondes en temps de chargement !<\/p>\n","protected":false},"excerpt":{"rendered":"Si, au d\u00e9but, Javascript est arriv\u00e9 discr\u00e8tement, pour \u00ab\u00a0\u00e9gailler\u00a0\u00bb un peu les pages, aujourd’hui, c’est un vrai feu d’artifice !
