Ask HN: Examples of applications built with Node.js?

39 pointsPeterRosdahl21 comments

It's hard to find any examples of applications built with Node.js. Do you have any examples on applications that are fully or partly built with Node.js?

Here's a little Node.js/CoffeeScript application I worked on for a contest at a conference:

Site: http://apiplayground.org

Source: http://github.com/jashkenas/api-playground/blob/master/src/a...

The source is interesting because it demonstrates something that you can't do easily with a regular Rails/Django app: nonblocking asynchronous calls to remote APIs, with synchronous responses to the ajax request.

I like it....

The Node.js IRC channel displayed as a live Wargames-like map: http://wargamez.mape.me/

It was discussed a while back on HN: http://news.ycombinator.com/item?id=1477084

This source is on GitHub here: http://github.com/mape/node-wargames

Also, Node Knockout (http://nodeknockout.com/, a 'build a node app in 48 hours' competition) is happening at the end of August, and I expect some cool stuff to come out of that.

The developers wrote about using node on their blog: http://debuggable.com/posts/parsing-file-uploads-at-500-mb-s...

Here's my account of using NodeJS in http://mixlr.com:

In fact, what would be a use case of Node.js?

I know it is a rather interesting tech but other than that what do you/would you use Node.js for?

Being 'interesting tech' is a pretty good reason to experiment/learn something in my book. But besides that:

- You get to write JavaScript on your back-end and your front-end.

- It's evented (like Twisted, EventMachine, etc) which has proven popular/robust/fast recently (think FriendFeed).

- It handles insane amounts of requests/second (due to non-blocking IO and V8 awesomeness among other things).

- Did I mention you get to write more JavaScript? :)

- It makes it pretty easy to implement servers for other protocols than just straight vanilla http -- for example WebSockets implementations and so on.

I'm hoping to use Node as my defacto replacement for all server side development.

Here's an offline-capable web application and underlying "network-straddling" framework running on Node:

Node is great for handling many concurrent clients. It extends the V8 interpreter with excellent low-level APIs: Posix, Tcp, Http, DNS. If you need to share Javascript code between client and server, Node is the best server-side Javascript environment you could choose to use.

What about ffi access? Could I load libmysql.so and use javascript wrapper around its functions or it must be implemented 'in pure Javascript'? ^_^

It would probably block node, so you're better off running it in another process and using the nonblocking IPC.

You could try the Projects / Applications section @ http://wiki.github.com/ry/node/

GitHub uses it for their download links to get an archive of a repository. There's a blog post about it somewhere.
