Basic usage

Define your component

from django_react import ReactComponent

class MyComponent(ReactComponent):
    source = 'path/to/file.jsx'

Create an instance of your component and pass it some props

my_component = MyComponent(
    some_prop='foo',
    some_other_prop=[1, 2, 3]
)

Render the component to its initial HTML

{{ my_component.render_to_string }}

Render JavaScript to mount your component

<script src="path/to/react.js"></script>

{{ my_component.render_js }}

The rendered JavaScript will automatically include:

• Your props, serialized to JSON
• Your source, which will have been JSX transformed and bundled with Webpack
• Initialization code that immediately mounts your component with React

Rendering the component to its initial markup ensures that your user will see your content immediately and React will mount the component as soon as the page has loaded the JavaScript.

Installation

pip install django-react

Add 'django_react' to your INSTALLED_APPS setting

INSTALLED_APPS = (
    # ...
    'django_react',
)

ReactComponent

Integrates server-side rendering of React components with Webpack's bundling.

from django_react import ReactComponent

# Define your component
class MyComponent(ReactComponent):
    source = 'path/to/file.jsx'
    
# Create an instance of your component with some props
component = MyComponent(
  foo=1,
  bar=[1,2,3]
)

# Render the component to its initial HTML
markup = component.render_to_string()

# Render JS to mount the component with React
js = component.render_js()

ReactComponent.render_to_string()

Render a component to its initial HTML. You can use this method to generate HTML on the server and send the markup down on the initial request for faster page loads and to allow search engines to crawl your pages for SEO purposes.

render_to_string takes an optional argument wrap which, if set to False, will prevent the the rendered output from being wrapped in the container element generated by the component's render_container method.

{{ component.render_to_string }}

ReactComponent.render_to_static_markup()

Similar to ReactComponent.render_to_string, except this doesn't create extra DOM attributes such as data-react-id, that React uses internally. This is useful if you want to use React as a simple static page generator, as stripping away the extra attributes can save lots of bytes.

{{ component.render_to_static_markup }}

ReactComponent.render_js()

Renders the script elements containing the component's props, source and initialisation. The script elements enable the browser to download your JS assets and add interactivity to a rendered component.

render_js is effectively shorthand for calling each of the component's render_props, render_source, and render_init methods.

{{ component.render_js }}

ReactComponent.render_container()

Renders a HTML element which Django React uses on the client-side to mount components with React. By default, render_to_string and render_to_static_markup are wrapped in this element.

render_container takes an optional argument, content which should be a string to be inserted within the element.

{{ component.render_container }}

ReactComponent.render_props()

Render the component's props as a JavaScript object.

The props will be defined within the browser's global scope under a variable name generated by the component's get_props_variable method.

{{ component.render_props }}

ReactComponent.render_source()

Render a script element pointing to the bundled source of the component.

The bundled component will be defined within the browser's global scope under a variable name generated by the component's get_variable method.

{{ component.render_source }}

ReactComponent.render_init()

Render a script element which will mount the component to the container created with the component's render_container, render_to_string, or render_to_static_markup methods.

{{ component.render_init }}

ReactBundle

A django_webpack.WebpackBundle which is configured to support loading of JSX files.

By default, a ReactBundle is configured to omit React from the generated bundle and instead rely on a global variable, window.React. By omitting React from the bundle, multiple components can be included in a single page without duplicating React's code.

You can extend the Webpack configuration by inheriting from ReactBundle and assigning the subclass as the bundle attribute on your ReactComponent subclass.

from django_react import ReactBundle, ReactComponent

class JqueryOptimisedBundle(ReactBundle):
    no_parse = ('jquery',)

class MyComponent(ReactComponent):
    bundle = JqueryOptimisedBundle

render_component()

Render a component to its initial HTML. You can use this method to generate HTML on the server and send the markup down on the initial request for faster page loads and to allow search engines to crawl your pages for SEO purposes.

Arguments:

• path_to_source: an absolute path to a JS or JSX file which exports the component.
• serialized_props: [optional] a string containing the JSON-serialized props which will be passed to the component.
• to_static_markup: [optional] a boolean indicating that React's render_to_static_markup method should be used for the rendering. Set this to True if you are rendering the component to static HTML and React will not be used on the client-side.

import json
from django.contrib.staticfiles import finders
from django_react import render_component

path_to_source = finders.find('path/to/component.jsx')

serialized_props = json.dumps({
    'foo': 1,
    'bar': [1, 2, 3],
})

# Render the component to its initial HTML
html = render_component(path_to_source, serialized_props)

Running the tests
