See projects Credits This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.Puppeteer is a JavaScript library from Google that allows developers to control Chrome via an API.Ī common use case is using Puppeteer for testing, where we can make sure that actions we perform in the browser work as we expect them to.īut we can also use it to automate tasks that we want to programmatically perform in the browser. evaluate ( '(element) => element.textContent', element ) Roadmap

querySelector ( 'h1' ) title = await page. Get an element's textContent: element = await page. Get a page's textContent: content = await page. If an expression is erroneously treated as function and an error is raised, try setting force_expr to True, to force pyppeteer to treat the string as expression. pyppeteer will try to automatically detect if the string is function or expression, but it will fail sometimes. pyppeteer takes string representation of JavaScript expression or function. Puppeteer's version of evaluate() takes a JavaScript function or a string representation of a JavaScript expression. The equivalent methods to Puppeteer's $, $$, and $x methods are listed below, along with some shorthand methods for your convenience: puppeteerĪrguments of Page.evaluate() and Page.querySelectorEval() Keyword argument style options (more pythonic, isn't it?): browser = await launch ( headless = True ) Element selector method names Open web page and take a screenshot: import asyncio from pyppeteer import launch async def main (): browser = await launch () page = await browser. Puppeteer's documentation and its troubleshooting guide are also great resources for pyppeteer users. One way to do this is to run pyppeteer-install command before prior to using this library.įull documentation can be found here. If you don't prefer this behavior, ensure that a suitable Chrome binary is installed. Or install the latest version from this github repo: pip install -U When you run pyppeteer for the first time, it downloads the latest version of Chromium (~150MB) if it is not found on your system. Install with pip from PyPI: pip install pyppeteer

Unofficial Python port of puppeteer JavaScript (headless) chrome/chromium browser automation library.

Before undertaking any sort of developement, it is highly recommended that you take a look at #16 for the ongoing effort to update this library to avoid duplicating efforts.

Note: this is a continuation of the pyppeteer project.
