Kriskowal/q. Les promesses avec Q et nodejs. Les promesses avec Q et nodejs Lorsque l’on commence à monter une application web qui tourne sous node, avec quelques requêtes http sur un autre serveur et une persistance dans une base mongodb on est vite pris par l’enfer des callbacks (en anglais callback hell et qu’on trouve également sous le nom de Pyramid of Doom).

Les promesses avec Q et nodejs

La solution la plus courante est d’utiliser les promesses. Simple… sur le papier en tout cas. Car dès que l’on dépasse le stade des 2-3 promesses à lancer l’une à la suite de l’autre on peut vite se retrouver à imbriquer des promesses les unes dans les autres, exactement comme on cherchait à ne pas faire avec les callbacks. Les promesses permettent de construire un enchaînement d’actions, synchrones ou asynchrones. L’article commence par présenter l’implémentation des promesses dans des cas simples, puis propose des solutions à des cas plus élaborés pour permettre de garder un code plus lisible et donc plus maintenable. Installation Approche naturelle avec des callbacks. Node.js on the Road: Node.js @ Yahoo - Developer Center. Like we were pretty early adopters for it.

Node.js on the Road: Node.js @ Yahoo - Developer Center

But when we saw that transition, we knew like this stuff is getting pretty solid, and so we started putting a lot of stuff on it.

Node.js on the Road: Node.js & Yahoo - Developer Center

I work at this little known startup that no one's ever heard of, and so when I was approached about this talk, about giving this talk, they wanted to me to focus a lot on production use of Node, and that's awesome. We use it in production, so I have a lot to talk about, but I thought it would be useful to explain to this audience that production at Yahoo has meant something different than production at other companies I worked at at the past. And the big thing about this, is most people think of production as something that keeps your company running, and at Yahoo, this means stuff that people actually use and what makes Yahoo money, right?

So this is what production is, but it's also for us, we have a lot of engineers—thousands and thousands of engineers, and it's very important that we keep them productive and working, and that's a big part of what my job is all about.

How to Build A Slackbot + Deploy an App to Heroku...

Folks would make these little bots or services — they’d greet you when you joined a channel, played trivia, Uno and other chat-based games with you. Unfortunately, if you wanted to make one yourself, you likely needed some knowledge of Perl, client-server architecture and a handful of Unix commands. Today, most will opt for a more aesthetic alternative to IRC. "Automatisez votre startup" par Julien Le Coupanec. Npm2dot.
