    *console.log()
    Rohan Jaswal
    @rohanjaswal2507
    @timruffles I put console.log() statements in JS code.
    Here is the gist:
    https://gist.github.com/rohanjaswal2507/119974d4c40f9cb8f2ea858b06dd9c5a
    And these are the errors I am receiving in the console.

    I would either ask on one of the jupyter gitter chats, or ask in the ipywidgets github issues. It looks clear that there are errors here.
    Rohan Jaswal
    @rohanjaswal2507
    @dsblank what are these errors related to? Moreover, the errors this time are different while the code is same.
    How is that possible?
    Douglas Blank
    @dsblank
    I don't know... I would have to dive into the issue. But you can get help from the jupyter people, I suspect. Is this based on @jdfreder's ipython-jsobject?
    Rohan Jaswal
    @rohanjaswal2507
    @dsblank Not exactly based on his work.
    Douglas Blank
    @dsblank
    Does his work directly?

    After running some widgets that integrate js in IPython, I noticed that this problem is very common.
    Error: Script error for "nbextensions/widgets/widgets/js/widget" http://requirejs.org/docs/errors.html#scripterror
    Douglas Blank
    @dsblank
    Made an issue here: jdfreder/ipython-jsobject#4
    Rohan Jaswal
    @rohanjaswal2507
    Cool. Will catch up there.
    Douglas Blank
    @dsblank
    @rohanjaswal2507 did you see @jdfreder's update? Can you try those changes and see if you can get his code to work?
    Rohan Jaswal
    @rohanjaswal2507
    @dsblank I am trying to get his code working. As he mentioned about the troubles with static assets installation, I am facing some troubles. Have asked him for more help.
    Douglas Blank
    @dsblank
    Ok, thanks for the update. I'll follow along over on the github issue.
    Rohan Jaswal
    @rohanjaswal2507
    Sure. By the way, I was trying to run that code and the problem I am facing is:
    Comm is not being registered.
    I think there is some problem here. Let me dig little more

    d3.js is available on a CDN at cloudflare: http://cdnjs.cloudflare.com/ajax/libs/d3/3.5.6/d3.js
    Is there any biojs library which which is also available through CDN. I tried the same with MSA(http://cdn.biojs.net/msa/0.4/msa.min.gz.js), but getting some error while loading the script in ipython.
    So, is there any other library which could be used in similar fashion to biojs?
    Should I go with this or try something else?
    Douglas Blank
    @dsblank
    @rohanjaswal2507 Let's get this code into github so that we can start to make progress, even drawing on some experts from either biojs, javascript, or ipython.
    Let's get the simplest example working of using biojs in ipython, whatever it is. And then see if you can get a jsobject interface working. Then, you should announce yourself to the biojs community, and identify what your plan is. Sound good?

    @timruffles
    @rohanjaswal2507 an easy way to get anything hosted is https://rawgit.com/. just get a reference to a specific version via a tag on gh, and you can use github as a CDN via rawgit
    @rohanjaswal2507 any sticking points on getting the first/hello world widget into iPython?
    Douglas Blank
    @dsblank
    @rohanjaswal2507 Did we lose you? We haven't heard from you for one week.
    Rohan Jaswal
    @rohanjaswal2507
    @timruffles, yes i have created the hello world widget. Will share the code in few hours. THE same widget with certain modifications can be used as a starting point.
    @dsblank no no. Actually I was traveling and could Not reply using the gitter Android app. The app isn't good.
    Just got back in room. Let me push the code to GitHub so that we can discuss further :smile:
    Rohan Jaswal
    @rohanjaswal2507
    @dsblank I pushed some basic code to github: https://github.com/rohanjaswal2507/biojsWidget
    and tell me if I am going wrong somewhere. biojs-io-fasta isn't being imported this way
    Rohan Jaswal
    @rohanjaswal2507
    I used browserify also. But that also didn't help in this case
    Rohan Jaswal
    @rohanjaswal2507
    @dsblank did you look into the code?
    Douglas Blank
    @dsblank
    @rohanjaswal2507 You should ask in the jupyter/notebook issues, stackoverflow, or on the jupyter mailing list. I'm going to be away from my development machines for awhile. But you should use the jupyter group to help solve issues like this.
    Rohan Jaswal
    @rohanjaswal2507
    Okay. I will ask people in jupyter notebook gitter room and then proceed further.
    thanks! :smile:
    Douglas Blank
    @dsblank
    Hopefully they can provide answers quickly and specifically.
    Rohan Jaswal
    @rohanjaswal2507
    Yeah, let's see
    Rohan Jaswal
    @rohanjaswal2507
    Created a ipython widget for MSA. Let me tidy my code and add a few examples and then I will upload the code to github.
    Further, I am thinking of creating such widgets for some more biojs components and then get them all together.
    Douglas Blank
    @dsblank
    Everything is working now? What was the issue?
    Rohan Jaswal
    @rohanjaswal2507
    @dsblank yes the problem is solved.
    And I pushed the initial code to https://github.com/rohanjaswal2507/msaWidget
    Actually, the script generated using browserify and the script available for MSA on cdn.biojs.sh didn't define MSA as module for requirejs.
    So, then I used webpack for the same.
    Now, I am working on addition of more features to MSA and then will wrap up some other biojs component in Ipython.
    Will add more examples to this repo very soon.
