Best way to integrate Python and JavaScript?

Question

Is it possible to integrate Python and JavaScript? For example, imagine you wanted to be able to define classes in JavaScript and use them from Python (or vice versa). If

Answer 1

You might also want to check out the PyPy project - they have a Python to (anything) compiler, including Python to Javascript, C, and llvm. This allows you to write your code in Python and then compile it into Javascript as you desire.

Also, check out the informative blog:

Unfortunately though, you can't convert Javascript to Python this way. It seems to work really well overall, they used to have a Javascript (made from compiled Python) version of the Bub'n'Bros game online (though the server has been down for a while).

Answer 2

How about pyjs?

From the above website:

pyjs is a Rich Internet Application (RIA) Development Platform for both Web and Desktop. With pyjs you can write your JavaScript-powered web applications entirely in Python.

Answer 3

PyExecJS is able to use each of PyV8, Node, JavaScriptCore, SpiderMonkey, JScript.

>>> import execjs
>>> execjs.eval("'red yellow blue'.split(' ')")
['red', 'yellow', 'blue']
>>> execjs.get().name
'Node.js (V8)'

Answer 4

Use Js2Py to translate JavaScript to Python, this is the only tool available :)

Answer 5

This question is not exactly young, but there have come up some alternatives:

• "Skulpt is an entirely in-browser implementation of Python."
• Brython - "A Python 3 implementation for client-side web programming"
• RapydScript - "Python-like JavaScript without the extra overhead or quirks"
• Transcrypt - "Lean and mean Python 3.6 to JavaScript compiler with multiple inheritance, sourcemaps, static type checking and selective operator overloading." (also on Github)

Answer 6

there are two projects that allow an "obvious" transition between python objects and javascript objects, with "obvious" translations from int or float to Number and str or unicode to String: PyV8 and, as one writer has already mentioned: python-spidermonkey.

there are actually two implementations of pyv8 - the original experiment was by sebastien louisel, and the second one (in active development) is by flier liu.

my interest in these projects has been to link them to pyjamas, a python-to-javascript compiler, to create a JIT python accelerator.

so there is plenty out there - it just depends what you want to do.
