Notebooks come alive when interactive widgets are used. Users gain control of their data and can visualize changes in the data. Learning becomes an immersive, fun experience. Researchers can easily see how changing inputs to a model impact the results. We hope you will add ipywidgets to your notebooks, and we're here to help you get started. ## Core Interactive Widgets The fundamental widgets provided by this library are called core interactive widgets. A [demonstration notebook](https://github.com/jupyter-widgets/ipywidgets/blob/master/docs/source/examples/Index.ipynb) provides an overview of the core interactive widgets, including: - sliders - progress bars - text boxes - toggle buttons and checkboxes - display areas - and more ## Jupyter Interactive Widgets as a Framework Besides the widgets already provided with the library, the framework can be extended with the development of **custom widget libraries**. For detailed information, please refer to the [ipywidgets documentation](https://ipywidgets.readthedocs.io/en/latest/). ### Cookiecutter template for custom widget development A template project for building custom widgets is available as a [**cookiecutter**](https://github.com/jupyter-widgets/widget-ts-cookiecutter). This cookiecutter project helps custom widget authors get started with the packaging and the distribution of their custom Jupyter interactive widgets. The cookiecutter produces a project for a Jupyter interactive widget library following the current best practices for using interactive widgets. An implementation for a placeholder "Hello World" widget is provided as an example. Popular widget libraries such as [bqplot](https://github.com/bqplot/bqplot), [pythreejs](https://github.com/jupyter-widgets/pythreejs) and [ipyleaflet](https://github.com/jupyter-widgets/ipyleaflet) follow exactly the same template and directory structure. They serve as more advanced examples of usage of the Jupyter widget infrastructure. ### Popular custom widget examples Examples of custom widget libraries built upon ipywidgets are - [bqplot](https://github.com/bqplot/bqplot) a 2d data visualization library enabling custom user interactions. - [pythreejs](https://github.com/jupyter-widgets/pythreejs) a Jupyter - Three.js wrapper, bringing Three.js to the notebook. - [ipyleaflet](https://github.com/jupyter-widgets/ipyleaflet) a leaflet widget for Jupyter. ## Install The stable version of ipywidgets can be installed with [pip](#with-pip) or [conda](#with-conda). If using JupyterLab, review the [Front-end extension for JupyterLab](#front-end-extension-for-jupyterlab) section. ### With pip ```sh pip install ipywidgets # Skip the next step if using JupyterLab or Classic notebook version 5.3 and above jupyter nbextension enable --py --sys-prefix widgetsnbextension ``` ### With conda ```sh conda install -c conda-forge ipywidgets ``` ### Front-end extension for JupyterLab Install the front-end extension to JupyterLab (note that this requires nodejs to be installed): - For JupyterLab 1.0.x and 1.1.x, use `jupyter labextension install @jupyter-widgets/jupyterlab-manager@1.0` - For JupyterLab 1.2.x, use `jupyter labextension install @jupyter-widgets/jupyterlab-manager@1.1` - For JupyterLab 2.x, use `jupyter labextension install @jupyter-widgets/jupyterlab-manager@2.0` See the [Installation](docs/source/user_install.md) section of the documentation for additional details. ### Developer install from source Installing from source is more complicated and requires a developer install, see the detailed [developer install](docs/source/dev_install.md) instructions. If you want to install ipywidgets from source, **you will need the [yarn](https://yarnpkg.com/) package manager version 1.2.1 or later**. To install the latest master version from the root directory of the source code, run ``dev-install.sh``. To only build the Python package enter ``pip install -e .``. ## Usage See the [examples](docs/source/examples.md) section of the documentation. The widgets are being used in a variety of ways; some uses can be seen in these notebooks: [Demo notebook of interactive widgets](https://github.com/jupyter-widgets/ipywidgets/blob/master/docs/source/examples/Index.ipynb) ## Change log [Change log](docs/source/changelog.md) ### Version Compatibility with Front-End Clients Refer to change log for more detail. | ipywidgets | JupyterLab | [Classic Notebook](https://github.com/jupyter/notebook) | [nbclassic](https://github.com/jupyterlab/nbclassic) | | ---------- | :--------------: | :--------------: | :---------: | | master | | - | TBD | | 7.6.3 | | | 0.2.6 | | **Legacy** | | | | | 6.x | | | - | | 5.x | | 4.2 | - | | 4.1.x | | 4.1 | - | | 4.0.x | | 4.0 | - | ## Contributing to ipywidgets [Developer information](CONTRIBUTING.md) ## License We use a shared copyright model that enables all contributors to maintain the copyright on their contributions.
