NGL component is a Dash component library.
Get started with:
- Install Dash and its dependencies: https://dash.plot.ly/installation
- Run
python usage.py
- Visit http://localhost:8050 in your web browser
See CONTRIBUTING.md
If you have selected install_dependencies during the prompt, you can skip this part.
-
Install npm packages
$ npm install
-
Create a virtual env and activate.
$ virtualenv venv $ . venv/bin/activate
Note: venv\Scripts\activate for windows
-
Install python packages required to build components.
$ pip install -r requirements.txt
-
Install the python packages for testing (optional)
$ pip install -r tests/requirements.txt
- The demo app is in
src/demo
and you will import your example component code into your demo app. - Test your code in a Python environment:
- Build your code
$ npm run build:all
- Run and modify the
usage.py
sample dash app:$ python usage.py
- Build your code
- Write tests for your component.
- A sample test is available in
tests/test_usage.py
, it will loadusage.py
and you can then automate interactions with selenium. - Run the tests with
$ pytest tests
. - The Dash team uses these types of integration tests extensively. Browse the Dash component code on GitHub for more examples of testing (e.g. https://github.com/plotly/dash-core-components)
- A sample test is available in
- Add custom styles to your component by putting your custom CSS files into your distribution folder (
ngl_component
).- Make sure that they are referenced in
MANIFEST.in
so that they get properly included when you're ready to publish your component. - Make sure the stylesheets are added to the
_css_dist
dict inngl_component/__init__.py
so dash will serve them automatically when the component suite is requested.
- Make sure that they are referenced in
- Review your code
-
Build your code:
$ npm run build:all
-
Create a Python tarball
$ python setup.py sdist
This distribution tarball will get generated in the
dist/
folder -
Test your tarball by copying it into a new environment and installing it locally:
$ pip install ngl_component-0.0.1.tar.gz
-
If it works, then you can publish the component to NPM and PyPI:
- Cleanup the dist folder (optional)
$ rm -rf dist
- Publish on PyPI
$ twine upload dist/*
- Publish on NPM (Optional if chosen False in
publish_on_npm
)Publishing your component to NPM will make the JavaScript bundles available on the unpkg CDN. By default, Dash servers the component library's CSS and JS from the remote unpkg CDN, so if you haven't published the component package to NPM you'll need to set the$ npm publish
serve_locally
flags toTrue
(unless you chooseFalse
onpublish_on_npm
). We will eventually makeserve_locally=True
the default, follow our progress in this issue.
- Cleanup the dist folder (optional)
