Reference App with Detailed Instructions

For more detailed instructions, see https://github.com/denisecase/pyshiny-penguins-dashboard-express. That project README.md has more detailed instructions, including reminders for Mac and Linux.

Get the Code

Fork this project into your own GitHub account. Clone your GitHub repo down to your local machine. IMPORTANT: Use your GitHub username in place of denisecase. GitHub CLI may work better on some machines.

git clone https://github.com/denisecase/cintel-07-tdash

Run Locally - Initial Start

After cloning your project down to your Documents folder, open the project folder for editing in VS Code.

Create a local project virtual environment named .venv, activate it, and install the requirements.

When VS Code asks to use it for the workspace, select Yes. If you miss the window, after installing, select from the VS Code menu, View / Command Palette, and type "Python: Select Interpreter" and select the .venv folder.

Open a terminal (VS Code menu "View" / "Terminal") in the root project folder and run these commands (for Windows - the activate command is slightly different Linux/Mac).

py -m venv .venv
.venv\Scripts\Activate
py -m pip install --upgrade pip setuptools
py -m pip install --upgrade -r requirements.txt

Open a terminal (VS Code menu "View" / "Terminal") in the root project folder and run these commands.

shiny run --reload --launch-browser app/app.py

Open a browser to http://127.0.0.1:8000/ and test the app.

Run Locally - Subsequent Starts

Open a terminal (VS Code menu "View" / "Terminal") in the root project folder and run these commands.

.venv\Scripts\Activate
shiny run --reload --launch-browser app/app.py

While the app is running, the terminal is fully engaged and cannot be used for other commands. To kill the terminal, click the trashcan icon in the VS Code terminal window.

After Changes, Export to Docs Folder

Export to docs folder and test GitHub Pages locally.

Open a new terminal (VS Code menu "Terminal" / "New Terminal") in the root project folder and run these commands. Remember to activate the environment first.

.venv\Scripts\Activate
shiny static-assets remove
shinylive export app docs
py -m http.server --directory docs --bind localhost 8008

Open a browser to http://[::1]:8008/ and test the Pages app.

Push Changes back to GitHub

Open a terminal (VS Code menu "Terminal" / "New Terminal") in the root project folder and run these commands.

git add .
git commit -m "Useful commit message"
git push -u origin main

Enable GitHub Pages

Go to your GitHub repo settings and enable GitHub Pages for the docs folder.
