@sellscript.
I could give you some output in the terminal if you'd like.  The documentation in the project sort of gives it all though and explains it pretty nicely.

@chennan
That sounds like it could be a fun web app type thing to make.  Not sure if it would fit in with this project though.

I'm looking to see if there's any analytical stuff that people would like to see built and hopefully add to the current idea.  I'm open to completely new projects though, so let me know if anyone's working on something cool or has some ideas

Hi All, 

A while back, I became interested in Bitcoin and wanted to contribute somehow to the community.  So I made a couple Node.js modules btc-stats and xchange.js
 
Btc-stats exposes a bunch of price analytic functions across bitcoin exchanges.  I finally now have some free time to work more on this project and was hoping to get some feed-back / feature requests so I don't start coding a bunch of random things I think could be useful. 

I'm still in this for the learning experience   Just trying to help the community and "level-up" my knowledge with bitcoin in general.

So.. I'm turning to the community.  What do you think could make this module better?  What features can I add that you would want?

Please!! give me suggestions on this or some other projects the community might need.  I'm very proficient with all things Web Development related

Hey, this sounds like it could be a good idea.  I'll pm you my personal info if you'd like to chat on development.  I think it might be a bit out of scope (too big for me to complete by the deadline) , but it's definitely something I could be interested in for the future. 
 
Can you give some specific cases of how this would work?  For instance, how would the next level (higher court if you will) be presented evidence from either side?  Maybe a simple sketch/explanation of the process flow would help clarify for me a bit. 

I'm about to apply to this if anyone is interesting in joining me (or maybe I'll make a new thread?).  If anyone has any suggestions on what you'd like to see created, please please let me know!  So far I'm thinking of creating something similar to the old ClearCoin service, or at the very least some platform to bring 3rd party escrow servicers to buyers/sellers and vice versa. 

We have another sort-of discussion on this here - https://bitcointalk.org/index.php?topic=1012569.0;all


I'd _really_ like to hear some more input with some ideas and hopefully form a team

I'd be very interested in helping on this.  Was actually just recently thinking of creating some escrow type service for the upcoming Coinbase hackathon (maybe a recreate of ClearCoin or similar).   
 
I'm currently working on a few projects, but can dedicate some time/effort if you let me know some specifics. 


shameless plug - follow me on github if you want to see what i have currently.

I'm working on bitfinex-node and then will move on to the other exchanges, then will aggregate all the exchanges api's into 1 common node module - xchange.js

Anyway, I think we need to research the old ClearCoin service (maybe reach out to the old dev once we collect our thoughts a bit more).  Basically , just restart his old service and see what we can do to keep it something sustainable.

@gogodr (I'll ping you on slack about this) and all the rest who might still be reading this...

 
  
I think this is the best and potentially only route we can take.  I'd be more than willing to help build an automated system which gives a super super simple platform for escrow parties to charge a fee for their services.  Something that can be standardized (same docs for all users, etc..), easily accessible, and easy to implement by the escrow individuals & exchanges  (perhaps we build out a large SaaS type service?).  
  
The 2 / 3 multisig seems to be the way to go, I think where us devs come in is facilitating this process to be as streamlined and "easy" as possible.  At the same time, there's nothing from stopping us on embarking on a commercial type side of it too.  Perhaps we could focus some efforts on reaching out to the different escrow servicers, exchanges, blogs, etc.. and let them know of our service.  A super easy product that we provide for a small (incredibly nominal i'm talking) fee.  
  
We could even open source the entire platform, and only charge (my entrepreneur side talking) for some easy to use web-portal or advertising.  I mean there's a million ways to go with this.   But yeah, I do think this fits the requirements for what the coinbase hackathon is looking for.

@gogodr  PM me if you'd like to collaborate on something bitcoin related in Node.js.  Even if we don't pursue this idea, I have a few others. 
 
Also, I created a Node.js Slack community if you'd like to join.  Alot of folks from the /r/node subreddit and node.js google group have joined.  It gives a nice platform to talk with other node.js devs in real-time.  (I see a few bitcoin folks too). 

nodeslackers.io to register. 

Or PM me and I'll give you my personal email.  I've been looking to partner up and learn more about the bitcoin space

Just realized you said 'average on last 24h' .  I have another module for analytics like that

https://github.com/jxm262/btc-stats
https://www.npmjs.com/package/btc-stats


Again, it's currently just for a few exchanges.  It's part of the plan to add everything though.

@emrebey

Yeah , eventually.  For the moment, I'm just creating Node modules for other devs to use (so there can be a bunch of websites using the same backing code). 

If you don't plan to make a ton of requests, I can throw up a basic Node server with a Rest endpoint for you.  Just pm me here or on that slack group, would only take me a few mins to do.


Eventually, I'll make a much bigger website with some cool features.  But that will be after I have the infrastructure in place.

Maybe follow me on github.  I don't have this currently, but will be actively working towards this...

https://github.com/jxm262

my xchange api gives the USD for a few exchanges - https://github.com/jxm262/xchange.js



PM me if you'd like.  Can change my priorities if needed.

Can I help out with this?  Or at least follow you on github so I can check back after it's been released? 

I'm currently learning a couple new tech stacks along with learning Bitcoin and this sounds like something cool I could contribute to, or at least study the code

Hi All,

So a couple weeks ago I made my first node.js module xchange.js. In an effort to keep learning, I extended the functionality into a new project btc-stats.

Btc-stats exposes a bunch of price analytic functions across bitcoin exchanges. Not sure if this is the correct subthread for this, but could I please get some feedback? I realize this is something small and simple, but I really need to level up as a programmer and feel this is the only way I've been getting good suggestions.

Github
https://github.com/jxm262/btc-stats

NPM
https://www.npmjs.com/package/btc-stats


List of functions available
- avg
- weightedAvg
- min
- max
- minVolume
- maxVolume
- minSpread
- maxSpread
- exchangeMinSpread
- exchangeMaxSpread

List of available exchanges (currently only uses btc-usd, but I can upgrade that later)
- bitfinex
- bitstamp
- okcoin
- btce
- bter
- hitbtc
- ccex

I still have ideas to create a full javascript wrapper library to integrate every bitcoin exchange's web api's into 1 common library. Would anyone find any interest if this was built? Any other ideas I can work on?

Update:  for your above..

parseFloat("15854420.40053001").toFixed(;

I know this is kind of something you can google yourself (or probably have), but here's a couple SO links with some more info.

http://stackoverflow.com/questions/1458633/elegant-workaround-for-javascript-floating-point-number-problem

http://stackoverflow.com/questions/2876536/precise-financial-calculation-in-javascript-what-are-the-gotchas

http://floating-point-gui.de/languages/javascript/


FWIW, I typically use parseFloat, then toFixed(2) when trying to convert to currency format.  Of course this depends on the precision required though.

Example:  parseFloat("23432.234324").toFixed(2);  //"23432.23"

That's actually on my todo list on my Trello board   But I'll probably make this as a separate project.  Maybe make a website with all of this stuff in 1 place.

But please, keep the suggestions coming!

Hi All,

I've been wanting to get more experience with Node.js and learn some more about Bitcoin (new to the community).  So I made a simple ticker library to help get the current spot price for a few exchanges.  I realize this is something super simple and easy to develop, but was hoping to get some feedback since it's my first time putting any code out in public.

https://www.npmjs.com/package/xchange.js

github source
https://github.com/jxm262/xchange.js

I currently only made it to pull the spot price for BTC-USD and works on these exchanges -
bitfinex
bitstamp
okcoin
btce
btc38
bter
hitbtc
ccex


I was thinking of recreating the Xchange java library (https://github.com/timmolter/XChange) , ported over to Node, but didn't know if anyone would find it useful.  This library is essentially a wrapper for _all_ the api's of a bunch of exchanges.  Kind of like a huge aggregator for java.

Can anyone give some feedback?  What features would you find useful, what other applications could people use?

Or are there any projects in need of Node or Scala devs?

@starfeeder

You basically just described the path I'm taking  I just started a nodejs project to get the ticker info for a bunch of exchanges.  I'm thinking of expanding this to make 1 huge node.js wrapper library to aggregate all the api's for all the exchanges (or most of them anyways).  

But before that, I thought to start by making the ticker then maybe some website to send email alerts for a given exchange/price.  Maybe add some charting , etc...

Actually, if we're doing similar things, would you ever want to collaborate?  I'm a java dev during the day, but have been trying to get my hands dirty with Node and Scala.
