Collaboration Between Python and JavaScript: A New Experience in Web Development

Introduction

In modern web development, the combination of Python and JavaScript enables seamless collaboration between the front-end and back-end. This article will introduce how to achieve interaction between Python and JavaScript through <span>Pyppeteer</span>, <span>PyV8</span>, and RESTful APIs.

1. Using <span>Pyppeteer</span> to Control the Browser

<span>Pyppeteer</span> is a Python library that can be used to control the Chromium or Chrome browser for automation tasks.

from pyppeteer import launch

async def main():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('http://example.com')
    content = await page.content()
    print(content)
    await browser.close()

import asyncio
asyncio.run(main())

2. Using <span>PyV8</span> to Run JavaScript Code

<span>PyV8</span> is a Python binding that allows JavaScript code to be executed within Python.

import PyV8

ctx = PyV8.JSContext()
ctx.enter()
result = ctx.eval("function add(a, b) { return a + b; } add(3, 4);")
print(result)

3. Implementing Front-end and Back-end Communication via RESTful API

Python can create RESTful APIs using <span>Flask</span> or <span>Django</span> for JavaScript front-end calls.

from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/add', methods=['POST'])
def add():
    data = request.get_json()
    result = data['x'] + data['y']
    return jsonify(result=result)

Conclusion

Through <span>Pyppeteer</span>, <span>PyV8</span>, and RESTful APIs, Python and JavaScript can achieve efficient collaboration to meet the demands of modern web development.
