Tapyr - Shiny for Python Application Template

Create and deploy enterprise-ready Shiny for Python dashboards with ease.

Introduction

Tapyr is designed for data scientists and developers seeking a seamless transition from development to deployment, this template uses uv for dependency management and pytest/playwright for comprehensive app validation/testing/quality assurance. Ideal for projects aiming for high-quality code and efficient deployment on Posit Connect.

Important

When we created tapyr, it used poetry for dependency management. Please check our docs for a quick poetry and uv comparison.

Getting Started

Check out our get started with tapyr blog post.

Using Devcontainer

To ensure a consistent development experience across all environments, we recommend using the devcontainer configuration with Visual Studio Code or DevPod for container-based development. If you prefer a local setup, follow the instructions below.

1. Start the Devcontainer: Open the project in VS Code and select "Reopen in Container" when prompted, or use the Command Palette (Ctrl+Shift+P) and choose "Dev Containers: Reopen in Container". Alternatively, use DevPod following their instructions.
2. Activate the virtual environment:

   source .venv/bin/activate

3. Run the application:

   shiny run app.py --reload

4. Execute tests:

   pytest

Note: The Devcontainer might limit some playwright features, such as codegen. For full functionality, consider a local setup.

Setting Up Locally with uv

For developers preferring a local setup without Devcontainer:

1. Install uv: Follow the installation guide.
2. Clone the repository and navigate to it.
3. Install dependencies:

   uv sync
   uv run playwright install --with-deps

4. Run the application:

   uv run shiny run app.py --reload

Attention: Follow any additional steps prompted by playwright install.

More information on uv can be found in the official documentation.

Setting Up Locally with pip

Although not recommended, you can set up the project using pip:

1. Clone the repository and navigate to it.
2. Create a virtual environment:

   python -m venv .venv
   source .venv/bin/activate

3. Install package with dependencies:

   pip install -e ."[dev]"
   playwright install --with-deps

4. Run the application:

   shiny run app.py --reload

Deployment on Posit Connect

Deploy your application to Posit Connect by: 0. Activate the virtual environment:

source .venv/bin/activate

1. Exporting your API Key:

   export CONNECT_API_KEY="your_api_key_here"

2. Configuring Posit Connect:

   rsconnect add \
   --api-key $CONNECT_API_KEY \
   --server <MY_CONNECT_URL> \
   --name <SERVER_NAME>

3. Deploying:

   rsconnect deploy shiny -t "Tapyr App" .

Replace placeholders with your server URL, server name, and API key. Verify the deployment on Posit Connect for successful upload.
