☕ Sponsor the Awesome Panel Project

If you would like to sponsor my time or the infrastructure the platform is running on, feel free to reach out. I would love to run https://awesome-panel.org on some decent hardware instead of a low end dev server in Azure.

You can also appreciate the work that has already been done if you

Thanks

🏃 Getting Started with the Awesome Panel Repository

🧰 Prerequisites

• A working Python installation.
  • Currently we are using v3.9.9.

🏎️ Installation

Clone the repo

git clone https://github.com/MarcSkovMadsen/awesome-panel.git

cd into the project root folder

cd awesome-panel

Create virtual environment and install Requirements

via python

Then you should create a virtual environment named .venv

python -m venv .venv

and activate the environment using one of the below commands.

source .venv/Scripts/activate

source .venv/bin/activate

or for windows

.venv/Scripts/activate.bat

On windows please manually install the geopandas requirements as described in using-geopandas-windows

Then you should install the local requirements

pip install -r requirements_local.txt -f https://download.pytorch.org/whl/torch_stable.html

or via Anaconda

Create virtual environment named awesome-panel

conda create -n awesome-panel python=3.9.9

and activate environment.

activate awesome-panel

On windows please manually install the geopandas requirements as described in using-geopandas-windows

Then you should install the local requirements

conda install --file requirements_local.txt

🧱 Build and run the Application Locally

Set the environment variables if needed

on bash:

export BOKEH_ADDRESS=localhost
export BOKEH_PORT=5006

on powershell:

$env:BOKEH_ADDRESS = 'localhost'
$env:BOKEH_PORT = 5006

Running the Application Locally

panel serve awesome_panel/apps/*.py --index home.py

or as a Docker container via

invoke docker.build --rebuild
invoke docker.run-server

🐋 Run the Application via Docker

If you don't want to clone the repo and build the docker container you can just use docker run to run the image from Dockerhub

To run the panel interactively on port 80

docker run -it -p 80:80 marcskovmadsen/awesome-panel:latest

To run bash interactively

docker run -it -p 80:80 --entrypoint "/bin/bash" marcskovmadsen/awesome-panel:latest

Code quality and Tests

We use

• isort for sorting import statements
• autoflake to remove unused imports and unused variables
• black the opinionated code formatter
• pylint for static analysis
• mypy for static type checking
• pytest for unit to functional tests
• locust for end-2-end tests.

to ensure a high quality of our code and application.

You can run most tests using

invoke test.all

You can run the Locust end-2-end tests via

invoke test.e2e

Please note you will need to have the Panel server running and point Locust to the correct host and port.

👷 Workflow

We use the power of Invoke to semi-automate the local workflow. You can see the list of available commands using

$ invoke --list

The application is

• built as a Docker image and tested via Azure Pipelines.
  • You can find the Dockerfiles here and the Azure pipelines yml files here.

• pushed to the Dockerhub repository marcskovmadsen/awesome-panel.

• released via Azure Pipelines

• to a web app for containers service on Azure on the cheapest non-free pricing tier

• We also deploy the awesome-panel docs on Read the Docs.

Build and Deploy the Awesome Panel Package

PLEASE NOTE THE AWESOME PANEL PACKAGE IS OBSOLETE AND REPLACED BY awesome-panel-extensions.

You can build the package using

cd package
python setup.py sdist bdist_wheel

If you want to publish the package to PyPi you should first

update the version number in the setup.py file. The format is YYYYmmdd.version. For example 20191208.1

Then you run

twine upload dist/awesome-panel-YYYYmmdd.version.tar.gz -u <the-pypi-username> -p <the-pypi-password>
