I commented in long form on Bruno's blog, but it's not showing for some reason. Here are the highlights: ...(paragraphs talking about my experience helping newcomers)... Node had "promises" early on and we learned a very important lesson with them. Hiding the non-blocking nature of code is bad!

Re: [nodejs] mobile web ui with node

Also some popular frameworks are backbone.js and ember.js (aka sproutcore 2.0). Backbone has no ui widgets, and I ember doesn't have much. There are *many* mobile frameworks these days. On Mon, Apr 16, 2012 at 9:46 AM, David Whitten wrote: > I understand that Rob Tweed has a system for making S

Re: [nodejs] A Framework Author Throwdown

I laughed at the part where Mikeal says that connect doesn't deserve to exist. I agree that database connectors shouldn't be packaged (primarily) as middleware layers, but remember the reason I designed connect in the first place. There were several competing http frameworks that were duplicating

Re: [nodejs] A Framework Author Throwdown

. There is an http plugin that provides the http service (it can use connect-compatible middleware). Other plugins can register routes and expose API endpoints to the browser. On Mon, Apr 16, 2012 at 1:13 PM, Tim Caswell wrote: > I laughed at the part where Mikeal says that connect doesn't de

Re: [nodejs] node modules which load dynamic .so files

If it's complaining about a .so file then it's probably something the .node file wants to dlopen. Node's require system only dlopens the .node file. What is the exact error message? On Mon, Apr 16, 2012 at 5:58 PM, SteveCronin wrote: > i've gotten a node module to successfully build but it fails

Re: [nodejs] OOP styles and standards

The question isn't entirely off-topic. The type of code you're writing affects the style of code you write. In particular prototype based objects are one of the techniques to make async callbacks organized. On howtonode, I've written a few articles explaining the various OOP techniques in JavaSc

Re: [nodejs] async.map

I don't know the async lib, but rolling your own map function is very easy. See this utility I bundle with my new safeRreturn micro-library. https://github.com/creationix/safereturn/blob/master/safereturn.js#L68-94 Also I have few questions and comments. Why does the small function take an callb

Re: [nodejs] Re: Request events handlers must be added in the same tick of the http request handler execution (I guess)

Doesn't .pause() now buffer internally? In my testing I haven't missed any events as long as I .pause() on the first tick. I would like to know if this is supported behavior. On Wed, Apr 18, 2012 at 3:49 PM, Mark Hahn wrote: > There is a buffered stream available from Mikeal that solves this p

Re: [nodejs] Node.js in a beagleboard::beaglebone

The beaglebone comes with an older version of Cloud9 IDE preinstalled. (cloud9 is a node app) So I would say, yes, it can be done. I imagine it's fast enough relative to the CPU power. Node on smart phones could get > 1000 request/second on the simple http hello benchmark. Startup time will matt

Could you be more specific? What kind of paths are these. Are you talking a virtual filesystem, or http request urls or something else? On Thu, Apr 19, 2012 at 3:06 AM, Masiar wrote: > Hello everybody. Sorry for the meaningless title, I would like to > create a Node.js extension that extends t
