jupyterlab_iframe's Issues

Install fails with Jupyterlab 2.1.5

Hello,

I just switched to jupyterlab 2.1.5 (hoping to get jupyterlab-latex running again), but now I get the following error when installing the Python package "jupyterlab_iframe".

== 2020-06-25 16:26:38,161 run.py:593 INFO parse_log_for_error (some may be harmless) regExp (?<![(,-]|\w)(?:error|segmentation fault|failed)(?![(,-]|\.?\w) found:

I am not using pip to install, but pure setup.py as pip fails (because PEP 517 has an issue with pip 19.0)

Autoprepend https for convenience

Port proxy code to tornado-proxy-handlers

404 errors

Background info: Im running JupyterLab v1.2.0 on Ubuntu and followed the jupyterlab_iframe installation instructions. I have not done the optional update to jupyter_notebook_config.py

When I enter a URL into the "Open IFrame" menu option, (ie http://tim.paine.nyc/), I only receive 404 not found errors. From looking at the output of a locally running (flask based) site when I try connecting to it (http://localhost:5000), I dont see any attempt to connect. However, wget http://localhost:5000 works as expected.

any thoughts where to start with debugging this?

multiple frames of same link broken due to widget reuse

fix revisions in requirements.txt

add linter

account for baseURL for hub deployments

no x to close widget

Show favicon as icon on tab

Consider distribution changes

https://github.com/timkpaine/jupyterlab_celltests/pull/31/files

CANCEL -> Cancel

jupyterlab_iframe/src/index.ts

Line 148 in 8289126

if (result.button.label === "CANCEL") {

Remove ujson

The ujson dependency requires gcc to be install as it is a c based library. This adds unnecessary overhead if the compilers are not available. I don't want to have to install build tools just for a simple JupyterLab widget.

Given that ujson is designed for performance, and the only place in this library that it is used is to stringify a very simple dictionary I would recommend switching it to the regular json package from the standard library.

This would also resolve #11.

Issues with linked resources in the iframe

Opening up `https://www.google.com` I see...

Because...

My browser end up trying to access something on my domain, that is in reality located on www.google.com domain, after a link referenced /something that resides on www.google.com.

<iframe src="https://my-jupyterhub.com/user/erik/iframes/proxy?path=https://www.google.com">
  <!--
    The link below is making my browser attempt to fetch:
    https://my-jupyterhub.com/images/branding/googlelogo/1x/googlelogo_white_background_color_272x92dp.png
    It should in this case instead try to fetch the same image but on the google.com domain.
  -->
  <img src="/images/branding/googlelogo/1x/googlelogo_white_background_color_272x92dp.png">
  <!-- ... -->
</iframe>

I'm not sure if this relates to #40 or not, so I decided to open a new issue. I'm also not sure if there is a good method to manage this situation in a sustainable way, perhaps sometimes links should act like this, but perhaps not always, I'm not sure.

Welcome page

Hi timkpaine,

thanks for the very useful extension.
I use it as part of the Jupyter/JupyterHub installation on our HPC clusters.

Is it possible to allow a default page to open in a tab on startup of jupyter using jupyterlab_iframe?
I would like to use this for a welcome page to introduce new users to the possibilities of JupyterLab.

Best,
Jens Henrik

add ts linter

add to launcher?

Hijack links clicked from within JupyterLab

For a notebook with a link to some reference documentation it would be nice if by default the web page was opened in jupyterlab_iframe so you could use the powerful phosphor layout capabilities to place it where you want rather than have it open in a new tab.

Ctrl-click could then as usual open in a new tab and there could be a context menu item for that too.

Install hangs in conda virutal environement but installs correctly on virtualenv

(Not really an issue for me, I am fine using a virtualenv ...)

Using python 3

virtual_env_install.log
conda_info.txt
conda_install.log

Let me know if you need any more info.

Thanks

Add conda recipe

tornado>=6

With the requirement of tornado 6.x the version 0.0.12 is limited to jupyter installations which can handle tornado 6.x by all its extensions. We tried to switch with our setup to tornado 6.x and see quite some issues. Now we are back on tornado 5.1.1 again.

Is it possible to avoid the requirement of tornado>=6 for your extension?

dist with twine

add support for configuring a static list of iframes to open directly from commands

404 Not found after first click

When I open an Iframe (e.g: https://github.com/timkpaine) I can see the web page, but when I click on a link (e.g: paperboy) I have the following issue:

404 : Not Found
You are requesting a page that does not exist!

Note: I use JupyterLab behind an Apache Reverse Proxy.

Is there a solution ?

Other question : How to backward and forward into the web page ?

Thanks

Make compatible with Jupyterlab 0.35.1

I am having difficulty installing the extension and assume it has to do with the version of Jupyterlab that I have installed.

missing ujson dependency

Hello, I just installed the extension by following the steps listed in the README:

pip install jupyterlab_iframe
jupyter labextension install jupyterlab_iframe
jupyter serverextension enable --py jupyterlab_iframe

But the last step failed:

$ jupyter serverextension enable --py jupyterlab_iframe

Looking closer:

So it looks like the ujson package should be listed as a required dependency!

After that it worked. Well, sort of! Some URLs display just fine (e.g. Wikipedia), others won't for various reasons:

Would be nice if such errors could be displayed instead of just showing a blank tab...

But it's an useful extension despite of these limitations, so thanks anyway!

Hi timkpaine,

I love the welcome page of jupyterlab_iframe.
For some reason the generated HTML-code for the welcome page includes "iframes/proxy?path". I can reproduce it with jupyterlab_iframe 0.0.11 installed with jupyter 0.35.6 .

The HTML-code reads like this:

Update docs to auto pull readme

Add JS tests

jupyterlab_iframe quirks with JupyterLab 0.35.2

Hi Tim,

I've incorporated your exceedingly useful extension into a Docker Image but have been running into issues while trying to dock/layout iFrame tabs and it appears to be stealing/hogging focus away from other phosphor widgets while it's running.

e.g., I can't reliably re-arrange/tile the workspace and layout tabs if the extension is actively in use and displaying iFrames.

To reproduce:

docker run --rm -it -e ENABLE_SPARK_MONITOR=True -e START_SPARK_HISTORY=True -e START_TENSORBOARD=True
-e START_DASK_DISTRIBUTED=True -e START_RAY_HEAD_NODE=True -p 8080:8080 dcoslabs/dcos-jupyterlab:latest start.sh jupyter lab --NotebookApp.token=
'' --NotebookApp.password=''

Point your browser to http://<hostname>:8080
Now open up iFrames for http://<hostname>:8080/tensorboard and http://<hostname>:8080/sparkhistory/ (trailing slash is required) and try to tile/arrange the iFrame tabs to have them laid out any which way you like and notice it's very hard to get it to go and stay just where you want them.

In addition, it sometimes becomes hard to re-launch notebooks that are running in the background but not actively being displayed if the extension is in use.

This is a very valuable extension that should ideally become a core part of JupyterLab, thank you very much for putting it together.

Quick user experience feedback of the README.md

Having the gif in the README is extreamly valuable! Thank you!!
It can be confusing to understand how this compares to the jupyterlab_html extension, but I now understand it as this extension will view the content of an provided URL, and jupyterlab_html will view the content of a .html file on disk.
I quickly figured out (thanks to the gif) what the first configuration did, but I didn't and still don't understood what the .welcome setting does.

NOTE: The Adding quicklinks section above is a screenshot!

Suggested actions

Describe the reasons this can be valuable. For me the key value of this plugin is to access a webserver that is available to the jupyterlab server, but isn't available to me accessing jupyterlab. For example, I use a tool called dask, it has some dashboard but this isnt exposed directly to the internet, and my jupyterlab is accessed remotely. So while jupyterlab running in the cloud, can access the dashboard, I running from another computer far away on another network, cant.
Also describe how it makes sense to also have the jupyterlab_html extension as well (if i got it right)
Clarify the .welcome setting

$ pip install jupyterlab_iframe
