Generic Java Script View node does not recognize an external library

[aworker]

Dear Knimers

I’m setting a minimalist workflow with an example on how to visualize a table using the Generic Java Script View node based on the DataTables library rendering. Unfortunately and for a reason I do not yet know, I believe the library is not recognized and I get the following error displayed on the debugging console of the Interactive View:

I tried to get inspired by previous thread bootstrap-table.js in Generic JavaScript View where @ptrwlr, @AnotherFraudUser, @swebb and @AlexanderFillbrunn participated and gave hints but I’m still struggling.

The workflow is the following:

Any advice would be greatly appreciated. Thanks in advance.

Hi @aworker,

I tried it with the logic of these two examples - but couldn’t get it to work either
(but maybe I also did something wrong - maybe someone of the others are able to help )

Generic JavaScript View - ReferenceError: Function is not defined

Hi @AnotherFraudUser, Here is a working example for Tabulator (using the same principle as the workflow that solved my issue). JS Library.knwf (343.5 KB) Cheers! Matheus

Using external JS libraries via webTemplate folder

Hi, I would also not recommend doing it that way. It makes the workflow almost impossible to debug when it is running somewhere else than the KNIME Server. I have attached a workflow that downloads the library code first and then passes it as a flow variable into the Generic JS View. You have to hack around with module.exports a bit, but it works. I would suggest you add some caching for the library so it is not retrieved every time you run the workflow. You can use a table writer to write the …

But would also be interessted in a possible solution

Hi @AnotherFraudUser,

Thanks a lot @AnotherFraudUser for your prompt answer and the links to other similar issues. I had a look at those and I neither could get it solved. Most probably, this problem just needs a right setting so the solution may not be very far from what the workflow is already achieving.

Other hints or possible solutions would be really welcome !

Thanks & regards,

Dear Knimers & KNIME Team Members,

Any takers for this challenging problem ?

The rendering should be the following :

But I get the following result

because the DataTables library is not recognized, as shown below:

The faulty workflow is the following:

Thanks in advance for your precious help !

Hi Ael,
I am not sure yet why and how, but I got it to work
You need to add the following lines before the $${SdataTables}$$ line:

var define = null;
var module = null;

With this I disable certain loading mechanisms for JS packages, but according to some console.log() outputs, those should be undefined anyways. If a JS expert can shed some more light on this, I would be happy to hear the reason
Kind regards,
Alexander

Hi @aworker,

In your workflow, you have created (HTML Based) a generic table with table creator node and used in Generic JavaScript View node. I wonder that can I convert a knime data table into HTML format to use in GJV Node like you did?

Best,
