We're thrilled that you're interested in contributing to NiceGUI! Here are some guidelines that will help you get started.
If you encounter a bug or other issue with NiceGUI, the best way to report it is by opening a new issue on our GitHub repository. When creating the issue, please provide a clear and concise description of the problem, including any relevant error messages and code snippets. If possible, include steps to reproduce the issue.
We follow a Code of Conduct to ensure that everyone who participates in the NiceGUI community feels welcome and safe. By participating, you agree to abide by its terms.
We are excited that you want to contribute code to NiceGUI. We're always looking for bug fixes, performance improvements, and new features.
To set up a local development environment for NiceGUI, you'll need to have Python 3 and pip installed.
You can then use the following command to install NiceGUI in editable mode:
python3 -m pip install -e .This will install the nicegui package and all its dependencies, and link it to your local development environment so that changes you make to the code will be immediately reflected.
Thereby enabling you to use your local version of NiceGUI in other projects.
To run the tests you need some additional setup which is described in tests/README.md.
There is no special Python version required for development. At Zauberzeug we mainly use 3.11. This means we sometimes miss some incompatibilities with 3.7. But these will hopefully be uncovered by the GitHub Actions (see below). Also we use the 3.7 Docker container described below to verify compatibility in cases of uncertainty.
You can also use Docker for development. Simply start the development container using the command:
./docker.sh up appBy default, the development server listens to http://localhost:80/.
The configuration is written in the docker-compose.yml file and automatically loads the main.py which contains the website https://nicegui.io.
Every code change will result in reloading the content.
We use Python 3.7 as a base to ensure compatibility (see development.dockerfile).
To view the log output, use the command
./docker.sh logWe use autopep8 with a 120 character line length to format our code. Before submitting a pull request, please run
autopep8 --max-line-length=120 --experimental --in-place --recursive .on your code to ensure that it meets our formatting guidelines. Alternatively you can use VSCode, open the nicegui.code-workspace file and install the recommended extensions. Then the formatting rules are applied whenever you save a file.
Our tests are built with pytest and require python-selenium with ChromeDriver. See tests/README.md for detailed installation instructions and more infos about the test infrastructure and tricks for daily usage.
Before submitting a pull request, please make sure that all tests are passing. To run them all, use the following command in the root directory of NiceGUI:
pytestNew features should be well documented in website/documentation.py.
By calling the element_demo(...) function with an element as a parameter the docstring is used as a description.
The docstrings are written in restructured-text.
Because it has numerous benefits we write each sentence in a new line.
Besides the documentation (see above) we collect useful, but compact examples. Each example should be about one concept. Please try to make them as minimal as possible to show what is needed to get some kind of functionality. We are happy to merge pull requests with new examples which show new concepts, ideas or interesting use cases.
To get started, fork the repository on GitHub, make your changes, and open a pull request (PR) with a detailed description of the changes you've made.
When submitting a PR, please make sure that the code follows the existing coding style and that all tests are passing. If you're adding a new feature, please include tests that cover the new functionality.
We welcome and support video and tutorial contributions to the NiceGUI community! As recently highlighted in a conversation on YouTube, creating and sharing tutorials or showcasing projects using NiceGUI can be an excellent way to help others learn and grow, while also spreading the word about our library.
Please note that NiceGUI is pronounced like "nice guy," which might be helpful to know when creating any video content.
If you decide to create YouTube content around NiceGUI, we kindly ask that you credit our repository, our YouTube channel, and any relevant videos or resources within the description. By doing so, you'll be contributing to the growth of our community and helping us receive more amazing pull requests and feature suggestions.
We're thrilled to see your creations and look forward to watching your videos. Happy video-making!
Thank you for your interest in contributing to NiceGUI! We're looking forward to working with you!
