Dash Material Design components for the Noos platform.
Project description
Dash Material Design Components
dash-material-components
allows to build consistently styled dashboards with complex and reactive layouts, following Google's Material Design principles.
The library leverages MUI React components for use with Plotly Dash.
This project has been initially boostrapped thanks to the Dash plugin cookiecutter.
Quickstart
Installation
The python package is available from the PyPi repository,
pip install dash-material-components
Usage as a library
Once installed, start using the Python components exactly like you would use other Dash component libraries,
import dash
import dash_material_components as dmc
# Compose a dashboard layout
text = dmc.Typography(text="Content...", component="p", variant="body2")
section_1 = dmc.Section(
id="section-1",
orientation="columns",
children=[text, text_2],
cards=[{"title": "Card 1a", "size": 3}, {"title": "Card 1b"}]
)
section_2 = dmc.Section(
id="section-2",
size=3,
children=[text, text_2],
orientation="rows",
cards=[{"title": "Card 2a", "size": 4}, {"title": "Card 2b"}]
)
page = dmc.Page(orientation="columns", children=[section_1, section_2])
navbar = dmc.NavBar(title="Custom dash")
layout = dmc.Dashboard(children=[navbar, page])
# Instantiate a Dash app
app = dash.Dash(__name__)
app.layout = layout
if __name__ == "__main__":
app.run_server()
Usage in notebooks
As pre-requisite, install the Jupyter Lab extension JupyterDash,
~$ pip install jupyter-dash
Then, copy the Dash snippet above into a Jupyter notebook cell and replace the Dash
class with the JupyterDash
class:
from dash import Dash
# Instantiate a Dash app
app = Dash(__name__)
app.layout = layout
app.run_server(mode='jupyterlab', host="0.0.0.0", port=8001)
Local development
Structure for a Dash component project
* project/
* python-package/ # The python package, output folder for the bundles.
* src/ # The javascript source directory for the components.
* components/ # Where to put the react component classes.
* index.js # The index for the components exported by the bundle.
* package.json # JS package build commands.
* webpack.config.js # The webpack configs used to generate the bundles.
* pyproject.toml # Python package build commands.
Install dependencies
The project is shipped with off-the-shelf scripts to manage node packages as well as a set of utilities for local development. If the yarn
node package manager is installed globally, install all javascript dependencies,
~$ yarn install --frozen-lockfile
:warning: the Dash material components has only been tested against Node.js v18.
And thanks to poetry
python package manager, create a virtual environnement,
~$ poetry install
Write a new React component
Compose your new Dash components in src/components
and make sure the React components are exported in your package entrypoint src/index.js
.
import NoosComponent from './components/NoosComponent.jsx';
export {NoosComponent};
:warning: the Dash material components are currently using MUI v.4, with the aim to transitionning to MUI v.5 shortly.
The corresponding Python component API is auto-discovered from the React component declared Props
, while the component Python docstring are automatically generated from the Props
React docstrings.
/** Used to auto-generate the Python component and docstrings */
const NoosComponent = (props) => {
const {text} = props;
return (
<div>
<p>{text}</p>
</div>
);
}
Box.defaultProps = {
text: 'Sample value',
};
Box.propTypes = {
/** Used to auto-generate the Python component and docstrings */
text: PropTypes.string,
};
export default NoosComponent;
:heavy_exclamation_mark: Be careful to use the correct formatting for your docstrings for them to be properly recognized.
Create a production build
Once your components have been included into your package entrypoint, run:
yarn build:js
, to generate the JavaScript bundledash_material_components.js
yarn build:py
, to generate the Python class files for the components.yarn build
, to generate everything: the JavaScript bundles and the Python class files.
In addition to buikld scripts, the project package.json
offers linter, formatter and hot-reloader:
yarn format
, to auto-format the React component code.yarn lint
, to check bundle compliance with ECMA standards.yarn watch
, to watch the library source directory and rebuild the JavaScript bundle.
