Refer to the readme for installation and development instructions.
Dash Core Components consist of pluggable components for creating interactive user interfaces. For generic HTML5 elements, see Dash HTML Components. Contributions are welcome! This repository's open issues are a good place to start. Another way to contribute is to write your own components using the Dash Components Archetype.
Please lint any additions to react components with npm run lint
. Rules defined in .eslintrc are inherited from dash-components-archetype
's eslintrc-react.json
Use the GitHub flow when proposing contributions to this repository (i.e. create a feature branch and submit a PR against the master branch).
In order to run the tests, you first need to have built the JavaScript
dash_core_components
library. You will need to build the library again if
you've pulled from upstream otherwise you may be running with an out of date
bundle.js
. See the instructions for building bundle.js
in the Testing
Locally section of README.md.
You also need to set the environment variable TOX_PYTHON_27
and with the
location of the Python 2 installations you want tox to use for creating the
virtualenv that will be used to run the tests. Note that this means you do not
need to install any dependencies into the installation yourself.
If you're using pyenv to manage Python installations, you would do something like this:
export TOX_PYTHON_27=~/.pyenv/versions/2.7.14/bin/python
You can configure the test server with the following variables:
If you run a special chrome set the path to your chrome binary with this environment variable.
If you encounter errors about Multi-server + Multi-processing when running under Python 3 try running the tests with the number of server processes set to 1.
DASH_TEST_CHROMEPATH=/bin/google-chrome-beta DASH_TEST_PROCESSES=1 python -m unittest -v test.test_integration.Tests.test_inputs
For now, multiple steps are necessary for publishing to NPM and PyPi, respectively. TODO: #5 will roll up publishing steps into one workflow.
- Create a pull request and tag the Plotly team (
@plotly/dash
) as well as an appropriate reviewer (frequent contributors are a safe bet). - After a review has been done and your changes have been approved, create a prerelease and comment in the PR. Version numbers should follow semantic versioning. To create a prerelease:
- Add
rc1
toversion.py
(./dash_core_components/version.py
) e.g.0.13.0rc1
- Add
-rc1
topackage.json
e.g.0.13.0-rc1
- Update the
unpkg
link in./dash_core_components/__init__.py
, replacing__version__
with your release candidate (e.g."0.13.0-rc1"
) - Run
npm run publish-all
.- If needed, ask @chriddyp to get NPM / PyPi package publishing access.
- If the
publish-all
script fails on thetwine
command, try runningtwine upload dist/dash_core_components-X.X.X.tar.gz # where xx.x.x is the version number
- Add
- Comment in the PR with the prerelease version
- Update the top-level comment to include info about how to install, a summary of the changes, and a simple example. For a good example, see the Confirmation Modal component.
- This makes it easier for a community member to come in and try it out. As more folks review, it's harder to find the installation instructions deep in the PR
- Keep this top-level comment updated with installation instructions (e.g. the
pip install
command)
- Make a post in the Dash Community Forum
- Title it
":mega: Announcement! New <Your Feature> - Feedback Welcome"
- In the description, link to the PR and any relevant issue(s)
- Pin the topic so that it appears at the top of the forum for two weeks
- For a good example, see the Confirmation Modal announcement
- Title it
- Download the latest plotly.js from the cdn:
$ wget https://github.com/plotly/plotly.js/releases/tag/v1.45.0
- Update
dash_core_components/__init__.py
plotly.jsexternal_url
- Update
MANIFEST.in
- Update
CHANGELOG.md
with links to the releases and a description of the changes. The message should state (see the existingCHANGELOG.md
for examples):- If you're only bumping the patch level, the heading is "Fixed" and the text starts "Patched plotly.js". Otherwise the heading is "Updated" and the text starts "Upgraded plotly.js"
- The new plotly.js version number, and the PR in which this was done
- All major or minor versions included, with links to their release pages and a summary of the major new features in each. If there are multiple minor/major releases included, be sure to look at all of their release notes to construct the summary. Call minor versions "feature" versions for the benefit of users not steeped in semver terminology.
- All patch versions included, with links to their release pages and a note that these fix bugs
- When bumping the dcc version, a plotly.js patch/minor/major constitutes a dcc patch/minor/major respectively as well.
