Dash Core Components

This package provides the core React component suite for Dash.

CircleCI Greenkeeper badge

Development

Testing Locally

  1. Install the dependencies with:
$ npm i
  1. Build the code:
$ npm run build-dev
  1. Install the library
$ cd dash-core-components
$ npm run copy-lib
$ python setup.py install

I recommend installing the library and running the examples in a fresh virtualenv in a separate folder:

$ mkdir dash_examples # create a new folder to test examples
$ cd dash_examples
$ virtualenv venv # create a virtual env
$ source venv/bin/activate # use the virtual env

(and then repeat step 3).

  1. Add the following line to your Dash app
app.scripts.config.serve_locally = True

Demo server

You can start up a demo development server to see a demo of the rendered components:

$ builder run demo
$ open http://localhost:9000

You have to maintain the list of components in demo/Demo.react.js.

Code quality and tests

To run integration tests (test_integration.py)

We run our integration tests on CircleCI with help from Tox. There’s a tox.ini file which holds the configuration, refer to tox's documentation for help. You may need to set environment variables in your terminal, like TOX_PYTHON_27 to my version of python that I wanted tox to use. So running:

export TOX_PYTHON_27=python2

set the TOX_PYTHON_27 env variable to point to python2, which is Python 2.7 running on my machine. You could also look in tox.ini and see which tests it runs, and run those commands yourself:

python -m unittest test.test_integration

Testing your components in Dash

  1. Build development bundle to lib/ and watch for changes

     # Once this is started, you can just leave it running.
     $ npm start
    
  2. Install module locally (after every change)

     # Generate metadata, and build the JavaScript bundle
     $ npm run install-local
    
     # Now you're done. For subsequent changes, if you've got `npm start`
     # running in a separate process, it's enough to just do:
     $ python setup.py install
    
  3. Run the dash layout you want to test

     # Import dash_core_components to your layout, then run it:
     $ python my_dash_layout.py
    

Installing python package locally

Before publishing to PyPi, you can test installing the module locally:

# Install in `site-packages` on your machine 
$ npm run install-local

Uninstalling python package locally

$ npm run uninstall-local
