twister-lib.js

[JM]

Am I right in understand that "twister-lib.js" is the browserify-d version of src/*  ?   But doesn't include anything from the node_modules?

[Julian Steinwachs]

No, the twister-lib.js file contains all needed node_modules. the one in the git-repo starts with the bencode package for example: https://raw.githubusercontent.com/Tschaul/twister-lib-js/master/twister-lib.js . Are you trying to use another module loader on top like webpack or systemJS? This second bread of module loaders (AMD-module loaders) was not around at the time i did the setup. I can imagine that they are incompatible.

I setup a test site at https://twister-proxy.tschaul.com/test.html where there is only the twister-lib.js files included. If you put e.g. Twister.getUser("tschaul").doProfile(x=>console.log(x.getAllFields())) into the console you should get my profile information pulled down. Maybe you can work your way back from there.

Also, do you have your source code public somewhere, that i could help you better.

Thanks for the input.  I don't have my code anywhere yet because I've really just been testing.  I have sample code from the examples etc pulling from my server that work fine with node.

What I am trying to do is to isolate all the requirements to run even just one example outside of nodejs or webpack etc.  For example, even with twister-lib.js, the src/* directory, and the examples, there are still missing dependencies. e.g. It is relying on node for more that are not included in twister-lib.js.

I can get around the need for nodejs "require", but it is still missing dependencies like httprequest.   e.g. I am getting a:

Exception: TypeError: undefined is not a constructor (evaluating 'new global.XMLHttpRequest()')

Maybe I am missing something and all the dependencies are included, but isn't the request wrapper in there still dependent on the nodejs request module for example?  (and the request module's dependencies)?

Thanks for the link to that site.  I did check out the https://twister-proxy.tschaul.com/test.html site, but on both Firefox and Chrome (both current versions) it is throwing an exception, in case you didn't see:

Likewise in the Chrome console:

I am back looking at this again.  I guess my real question was which modules are not included in the browserify bundle, but would be handled in the browser or node.  For example, there are modules built into node.js that I don't think are in the browserify bundle.  In short, I'm trying to figure out what are the external dependencies in there?  If I use 

npm-remote-ls twister-lib-js

or (on my local test project)

npm ll

then it appears that it is at minimum there are dependencies that which don't seem to get browserify-d in there:

buffer

crypto

punycode

As far as request goes, maybe it is included, but I am not sure.

crypto-browserify is included in some spots, but so is just crypto.  Ditto buffer is missing if you try to run it outside a real browser or node.

I think having the code with clear module dependencies / clear external APIs are required is important and it is pretty close, but I can't find the last few missing items.  ;-)

I hope this is making sense

Thanks!

[JM]

e.g.  If you wanted to run it in JSC, clearly the builtin required node modules aren't there and it doesn't look like browserify is getting them all in there.

Hi Julian,

Have you done any work on twister-react recently?  Or twister-js-lib?

Cheers!

[Julian Steinwachs]

No, both repos are resting since 3 years.
