playwright-har-tracer

A Python implementation version of Playwright's HAR tracer. It is equivalent to playwright v0.13.x’s HAR tracer implementation.

Motivation

Playwright's HAR tracer is implemented to generate HAR as a file. I need to get HAR as a Python object rather than a file.

• playwright-har-tracer's HarTracer generates HAR as a dataclass object.

⚠️ Limitations

• Tested with Python 3.8+
• Tested with Chromium only
• Supports the async API only

Installation

pip install playwright-har-tracer

Usage

import asyncio
from playwright.async_api import async_playwright
from playwright_har_tracer import HarTracer


async def main():
    async with async_playwright() as p:
        browser = await p.chromium.launch()
        context = await browser.new_context()

        tracer = HarTracer(context=context, browser_name=p.chromium.name)

        page = await context.new_page()

        await page.goto("http://whatsmyuseragent.org/")

        har = await tracer.flush()

        await context.close()
        await browser.close()

    print(har.to_json())


asyncio.run(main())
