PyReact is a Python wrapper around the React JavaScript library and JSX.

Specifically, it provides an API to transform JSX files into JavaScript from within your Python application, as well as providing access to the latest React build.

PyPI: PyReact is hosted on PyPI, and can be installed with pip:

$ pip install PyReact

Alternatively, add it into your requirements file:

PyReact==0.6.0

Dependencies: PyReact uses PyExecJS to execute the bundled React code, which requires that a JS runtime environment is installed on your machine. We don't explicitly set a dependency on a runtime environment; Mac OS X comes bundled with one. If you're on a different platform, we recommend PyV8.

Transform your JSX files via the provided jsx module::

from react import jsx

# For multiple paths, use the JSXTransformer class.
transformer = jsx.JSXTransformer()
for jsx_path, js_path in my_paths:
    transformer.transform(jsx_path, js_path=js_path)

# For a single file, you can use a shortcut method.
jsx.transform('path/to/input/file.jsx', js_path='path/to/output/file.js')

You can also use transform_string(jsx) method to transform strings:

from react import jsx
transformer = jsx.JSXTransformer()
js = transformer.transform_string(jsx)

Django: PyReact includes a JSX compiler for django-pipeline. It has been tested with django-pipeline 1.3.20, but may work with other versions too. Add it to your project's pipeline settings like this:

PIPELINE_COMPILERS = (
  'react.utils.pipeline.JSXCompiler',
)
