Install dash without plotly?

Dash Python
1

I wanted to know if there was a way to install dash without plotly ?
(Or alternatively, a minimal version of plotly - I will not be using any plotting features)

The package size is too large because of plotly.

I couldn’t find any post about it, so please redirect me if I am missing something.

Hmm i think they are pretty well baked together. I guess you could try installing both then removing the individual dependencies but that’s just my non-tested guess.

Out of curiosity, can i ask why you only want dash without plotly?

dash has a plethora of features and community-made components (dbc, dmc) which are perfectly capable of making a non-data-based website. The most efficient way to do so? probably not, but its not that infeasible

I have made (and will continue to make) complex multi-page apps on Dash because I don’t really want to learn a js framework, as I am not a web developer, and it is so easy to do on Dash.

(will try and update you)

I’m just thinking, but I don’t think that plotly goes onto the browser unless you use a dcc.Graph.

I think as long as you steer clear of that, you should be fine.

Hmm, but just uninstalling plotly results in the following traceback:

Traceback (most recent call last):
  File "main.py", line 1, in <module>

Try installing orjson

that didn’t change anything

Why do you not want the plotly library exactly?

Space requirements or is the browser running slow?

space requirements, i don’t think it should affect performance if there are no graphs

I think the only way to fix this is just to delete the parts from the plotly library that are not necessary. This process will be trial and error. Go into the plotly folder in your virtual environment, delete a folder and see if your app still works. Note down the folders that you are allowed to delete, so that you can build a script later to automatically delete the unnecessary folders after you updated plotly to a later version. If you are not allowed to delete a folder, you can go in the folder and start deleting subfolders.

One thing I noticed is that there is a jupyterlab_plotly folder that also gets installed. Most likely this one can also be removed.

If you do decide to sit down for this, consider sharing your results here, I would be very interested to see them.
