Creating a notebook ipynb file using notebook json which we get from a server

[anmi...@umich.edu]

Hi,

I am working on this tree extension, which puts a button on the toolbar (see the attached file). On clicking the button, I fetch a notebook json from a server and store it in a javascript variable. I would like to create and open the notebook using the json received for the user to start working on. 

I am aware of the working in the contents.js file in the services folder, but not sure how I can create a file using what's available. 

Best,

Anant

It's probably easiest to create a file on the server side, then you just need to open a window with the right URL to view it.

To do this from the Javascript side, you'd need to get the data from the server and then send it straight back to be saved to a file.

Hi, 

By the server, I meant a server which is running on an AWS lambda. The functionality that I want is to create a notebook using the json which I have received from the server. Think of it as a function which is used to create a new empty notebook. But in my case, I would like to create a notebook with a pre-filled notebook json I have. 

Is that making sense?

Best,
Anant

I think I need to use Contents API.

Ah, I see - it's coming from a different server. In that case, you'll need to do something like this:

// Valid notebook JSON - see http://nbformat.readthedocs.io/en/latest/format_description.html

var nb_json = {"nbformat": 4, ...}

var model = {type: "notebook", content: nb_json}

Jupyter.contents.save("folder/filename.ipynb", model).then(function() {

    console.log("Saved notebook");
})

I haven't tested this, so it might need tweaking a bit.
