Thanks so much for dash-tools!

Is your feature request related to a problem? Please describe.
Based on the post by Heroku on their blog, it will no longer be possible to have a free account. I would like to request information on how I could deploy to another free site, if there are any. I'm open to any suggestions, but perhaps netlify would work.

Describe the solution you'd like
Again, a possible solution is to deploy to netlify.

Describe alternatives you've considered
I"m not aware of any working alternatives than to pay for Heroku.

Additional context
n/a

Is your feature request related to a problem? Please describe.
I work with video datasets and I don't know about a good way of deploying videos/gifs using dash. I am using dash-gif-component for creating a dash app with GIFs and I tried dash-tools advanced template. The app was working locally but the path was broken when deployed on Heroku.

Is there a way to deploy a GIF app to Heroku?

Additional context
Add any other context or screenshots about the feature request here.

Is your feature request related to a problem? Please describe.
Dockerfiles generated by dashtools docker --init default to the base image default user (in this case root). Best practice is to run container processes as a non-root user.

Describe the solution you'd like
Update the process that generates Dockerfiles to create and use a non-root user.

Describe alternatives you've considered
Alternative would be to continue running as root user, but this is not advised and is also easy to prevent.

I will submit a PR to fix this Issue shortly.

@Coding-with-Adam what are your thoughts on adding a section to the README for deploying an existing dash app? Eg. If I already have a working app, what steps should I take to deploy it?

Example A and B in README are great, but use dashtools --init to create the app. I might like to see a section that explains how to upload my existing app:

1. Make sure app.py is in src directory
2. Make sure to include server=app.server

Do you think having another example for this would be good?

Moving snehilvj/dash-iconify#1 to dash-tools issue.

Hi @andrew-hossack, I came across your project sometime back and I like what you are doing. Thanks for including dmc and dash iconify.

dash-iconify : I am not sure if a standalone template which uses just dash-iconify makes sense. It's more like a utility. But let me know your thoughts.
dmc : If you are willing, I can come up with more examples to address the following using dmc:

• side nav bar
• dark theme
• dmc with dash-iconify
• responsive top navigation
• any other use case you can think of

PS: We can move this issue to dash-tools if you prefer that.

Add ability to eb deploy

Create a docker command to turn current project into a docker container.

Pipreqs fails to generate requirements.txt. Seems to happen on Windows only. Might be an issue with non utf-8 encoded files.

Issue requires more investigation.

When running the dashtools heroku --deploy, I constantly get this error

dashtools: Required file requirements.txt not found. Create one automatically? dashtools: Continue? (y/n) > y dashtools: Creating requirements.txt Usage: pipreqs [options] [<path>] dashtools: Error creating requirements.txt dashtools: Are you in a valid dash app directory? dashtools: Exiting

I'm on windows. I'm not using a virtual environment so I think that has something to do with it?

I've even made the requirements.txt file myself and still get that error.

Could be because I'm multiple pages as well.

Maybe my folder setup is wrong?

When I develop Dash apps, I almost always run them with while true; do python app.py; sleep 1; done such that if, while I'm typing, I save a file with, say, a syntax error, I can just glance at the console, see the error, fix it and save the file again and the app reboots. If I don't do this, the first syntax error crashes the app and I need to switch to my terminal and re-execute python app.py.

So the feature request is a command like dashtools run (which does the equivalent of python app.py) and dashtools run --restart (which does the equivalent of my restart loop, perhaps with a numeric argument for how many seconds to wait or something).

dashtools could do some cool stuff like parse the output and apply nice colors, or even parse the output and notice that it's the same as the last crash and just increment a counter saying "app crashed N times with the error above" or whatever, to make it a nicer developer experience.

https://dash-tools.readthedocs.io/en/latest/commands/templates/index.html doesn't render markdown like it should

Describe your context
I am trying to host my dash app on render. I can go through the gui checklist but when I hip deploy to render it redirects me to render and I see the following message

• replace the result of dash-tools --version below

dashtools 1.10.1

• please tell us what operating system you are using

linux POPos

Describe the bug

It seems to me that there is some path concatenation that is not working correctly and in quickly scanning your repository I believe that on line 27 of deployPage.py is where this is occurring.
When looking at my github i see that dashtools is successfully pushing to my github repo(DashTool Automatic Push - 10/25/2022 @ 9:01:44)

I created a pull request that might work. Not sure what else uses that function though

Expected behavior

I expect it to push to render

Thanks for your work this is a great repo

Current behavior:

> dashtools gui
dashtools: Dashboard started on http://127.0.0.1:8050/

Hi Andrew, a simple one:

Log from Heroku:

That's it, thanks!

Form @1DS20CS083 _Harsha S:
@andrew H OMG aren't you the guy who made this? Thank you so much fam. It used to take a hour to upload stuff before, now it takes like a few minutes :D, thank you kind sir

P.s. there is a small error when I use pymongo in the project, it needs dnspython module to work. When I deploy the app in the requirements file, it only has the pymongo module but ignores the dnspython module so the website doesn't work. I fixed this issue easily by adding the dnspython module in the requirements file but I thought I would let you know.

Version 1.6.2 advanced template does not work when running, needs to be fixed
