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 <a href="http://pyjs.org" rel="noreferrer">pyjamas</a>, 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.

Many of the examples are years out of date and involve complex setup. You can give <a href="https://github.com/extremeheat/JSPyBridge/" rel="nofollow noreferrer">JSPyBridge</a> a try (full disclosure: I'm the author).
It's a bi-directional bridge that lets you use JavaScript code from Python, and vice-versa. That means that Python code can call JS callbacks, and JS code can call Python callbacks.
Access Python from JS, numpy + matplotlib example, with the ES6 import system:
<pre class="lang-js prettyprint-override"><code>import { py, python } from 'pythonia'
const np = await python('numpy')
const plot = await python('matplotlib.pyplot')

// Fixing random state for reproducibility
await np.random.seed(19680801)
const [mu, sigma] = [100, 15]
// Inline expression evaluation for operator overloading
const x = await py`${mu} + ${sigma} * ${np.random.randn(10000)}`

// the histogram of the data
const [n, bins, patches] = await plot.hist$(x, 50, { density: true, facecolor: 'g', alpha: 0.75 })
console.log('Distribution', await n) // Always await for all Python access
await plot.show()
python.exit()
</code></pre>
Through CommonJS (without top level await):
<pre class="lang-js prettyprint-override"><code>const { py, python } = require('pythonia')
async function main() {
 const np = await python('numpy')
 const plot = await python('matplotlib.pyplot')
 ...
 // the rest of the code
}
main().then(() =&gt; python.exit()) // If you don't call this, the process won't quit by itself.
</code></pre>
Access JS from python:
<pre class="lang-py prettyprint-override"><code>from javascript import require, globalThis

chalk, fs = require(&quot;chalk&quot;), require(&quot;fs&quot;)

print(&quot;Hello&quot;, chalk.red(&quot;world!&quot;), &quot;it's&quot;, globalThis.Date().toLocaleString())
fs.writeFileSync(&quot;HelloWorld.txt&quot;, &quot;hi!&quot;)
</code></pre>

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 so, what's the best way? I'm interested not only if this is possible but if anyone has done it within a "serious" project or product.

I'm guessing it would be possible using <a href="http://www.jython.org/Project/" rel="noreferrer">Jython</a> and <a href="http://www.mozilla.org/rhino/" rel="noreferrer">Rhino</a>, for one example, but I'm curious whether or not anyone's ever actually done this, and if there are solutions for other platforms (especially <a href="http://en.wikipedia.org/wiki/CPython" rel="noreferrer">CPython</a>).

Best way to integrate Python and JavaScript?

服务器

编译器

解释器

Python

JSON

有没有可能集成Python和JavaScript？例如，假设您希望能够在JavaScript中定义类并在Python中使用它们(反之亦然)。如果是这样，最好的方法是什么？我感兴趣的不仅是这是否可能，而且是否有人在“严肃的”项目或产品中做到了这一点。例如，我猜使用和是可能的，但我很好奇是否有人真正这样做过，以及是否有针对其他平台(特别是)的解决方案。
