Does node.js not include packages in opkg yet?
-
@Steve-Fister Can you send me a copy of your sources? I would like to try it out to figure out what the issue is. I've been able to make HTTP requests using node without much issue on the Omega, and I don't think the twitter login system requires any special HTTP request features.
-
@Boken-Lin You can grab one from here that I am currently using: https://github.com/ttezel/twit
I've also tried:
https://github.com/SpiderStrategies/node-tweet-stream
https://github.com/desmondmorris/node-twitterFWIW, I don't think its a HTTP request problem either. I'm hoping you find similar issues (although I would LOVE to get this working!), maybe it will identify an issue somewhere.
Thanks!
-
@Steve-Fister Ok. I'll try it out and let you know!
-
@Boken-Lin FWIW, I have tested the node.js request module and have verified that I can indeed receive content from a HTTP request.
-
@Steve-Fister Yeah. I'm still trying to pinpoint the issue that's causing the error. So far all HTTP requests have been okay.
-
@Steve-Fister @Boken-Lin I have given this a try, maybe I have a bit more info.
First I copied over twit. I built it on my mac. I ran into issues with 2 things, har-validator and uuid. These both have bin files. The error I get actually has to do with creating the symlinks when extracting the tar file.
tar: can't create symlink from ./twitter/node_modules/twit/node_modules/request/node_modules/.bin/har-validator to ../har-validator/bin/har-validator: Operation not permitted ./twitter/node_modules/twit/node_modules/request/node_modules/.bin/uuid tar: can't create symlink from ./twitter/node_modules/twit/node_modules/request/node_modules/.bin/uuid to ../node-uuid/bin/uuid: Operation not permittedI tried to create these myself but wasn't able to. I then ran the simple hello world example, which doesn't use streams like Steve was using, and I don't get a code error, but it comes back telling me it can't authenticate. I tried this same example on my mac it is is successful.
Twit has one dependency, request, which has many including the two mentioned above. I decided to create another project using just it - no twit. I get the same errors about the bin files, but I was able to connect to and open and display a web page. So the basic request functionality is working, but not when it comes to authenticating. I can see that there would be issues with the bin files if they were used. Not sure what har-validator is needed for.
I guess we could try to cross-compile request to get the right form of the binaries and try again to link them or just copy them.
-
Oh crap. Just realized I wasn't using 0.10.5 version of node. Tried to use nvm to switch version but not sure it is completely working. It errors doing a search. I don't think I can find twit that works with 0.10.5. I tried package twit-old, it only uses oauth, but I can't get it to work on my mac.
-
@Chris-Ward excellent info! I was trying to narrow it down to a specific module, but hadn't gotten to uuid or har-validate. I did test it in v0.10.0 & v0.10.5 on my Mac and it still continued to work. At least we are on the right track! I'll see if I can't cross compile those two modules for use on this architecture. Thanks!!
-
@Steve-Fister What did you use to get v0.10.5 node on your machine? Windows? OSX? Like I said NVM gave me issues. I couldn't find the twit package, and twit-old wasn't working on my mac.
-
@Chris-Ward I used NPM on my Mac to get the specific version. I actually downgraded my Mac from the latest version to this one without issue.
-
@Steve-Fister yea, ok. I might try that, but I use node for work, and need a different version for that. NVM has worked for me in the past, but I haven't used this old a branch before.
-
@Boken-Lin Ok, so I'm having trouble figuring out how to cross-compile a node package (i.e. twit). I've already cross compiled nodejs using JXCore, but can't seem to find any info on doing this for just a package/module. Any help is appreciated!
-
Hi @Steve-Fister, We are still trying to figure this out ourselves as well. As soon as we figure out a systematic way to do it, we'll post a tutorial on it.
Currently you just need a package to use the Twitter streaming API? I'm pretty sure there should be a way to use the twitter streaming API without using the
requestpackage, which is required bytwitand a few other twitter modules for node.js. To solve your immediate problem, I will try to hack together a native-only implementation of the twitter streaming API. Once we have a consistent method to cross-compile node modules, we can then migrate over to existing node modules.Does that work?
-
@Boken-Lin Ok, that's kind of what I figured. Thought I could be Superman, guess not
Yes! If you could figure out a way to get a Twitter stream working in node on the Omega I would OWE YOU BIG TIME!!!!!!
-
@Steve-Fister There you go: https://github.com/OnionIoT/simple-twitter-stream. I've tested it out and it seems to work. There are probably some bugs, but they should be easy to debug.
Cheers!

You are a Super Hero! Thank you so much for the help on this! I now have my project completely running. I will share the details with the community soon. It's been a very fun little project and I've learned a lot since I unboxed the Omega. My project is not all that special, but it's fun and quirky and uses the Omega!!
Thank you again!
-
@Steve-Fister Awesome! Looking forward to seeing it

Well, here's my little project! I used a small electro-mechanical toy bird which I purchased online for about $10 (bought a couple in case I made fried parakeet). The bird uses a photoresistor to detect movement in front of the bird, like a hand, and causes the bird to move its head/tail and tweet.
I remove the photoresistor and connected the pins to one of the Omega's GPIO pins, set to high. With the use of Node.js and a Twitter Streaming module (Thanks @Boken-Lin!!!), I was able to get the bird to chirp by setting the GPIO pin to low, based on the keyword being found in the Twitter Stream!
I have a short little video of it in action here: https://www.dropbox.com/s/earpuvg5vgdgw24/20151221_145132.mp4?dl=0
Again, thanks for the help of the Onion Community! Couldn't have done it without you. Looking forward to the next, more in-depth project!

@Steve-Fister Wow! That's so cool!!!
Thanks for sharing

@Boken-Lin Any updates on supporting later versions of node.js (>4)?
