It’s finally here! Along with it’s announced rebranding to ‘Posit’, RStudio also released it’s alpha version of ‘Shiny for Python’. Here’s how you can get started creating and deploying Shiny apps in Python.

Set-up

The first step is going to be installing the necessary packages and creating a sample application.

1. Install shiny

pip install shiny

2. Create starter application

shiny create app_name

3. Run your new app

shiny run --reload app_name/app.py

Successfully running each of the above commands will leave you with a sample app that looks like the following:

Additional set-up resources from R Studio:

• Get started
• Installing Shiny for Python

Configure

The next step is to configure your local environment in preparation for deploying your newly created application.

1. Install rsconnect-python

pip install rsconnect-python

2. Configure rsconnect-python

rsconnect add --account [ACCOUNT] --name [NAME] --token [TOKEN] --secret [SECRET]

The variables can be retrieved by going to your shinyapps.io account, selecting your name in the top-right corner, and pressing “tokens”.

You will then see a screen that looks like this:

3. Generate manifest file

rsconnect write-manifest shiny app_name/

After generating your manifest file, the file structure of your app should be as follows:

app_name/
   app.py
   manifest.json
   requirements.txt

Deploy

Finally, you’re going to deploy your app to shinyapps.io. Your deploy command will be structured like this:

rsconnect deploy shiny /path/to/app_name --name [NAME] --title app_name

For example:

rsconnect deploy shiny /app_name --name trevorfrench --title app_name
