This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.To download files with Puppteer we can either the browser's fetch feature - which will download the file into a javascript variable - or find and click the download button which will download the file to the browser's save directory: // start puppeteerĬonst browser = await puppeteer.launch() Īwait page._nd('Page.
Which force pyppeteer to treat the string as expression.Įxample to get page content: content = await page. String is treated as function and error is raised, add force_expr=True option, The browser is downloaded to the HOME/.cache/puppeteer folder by default (starting with Puppeteer v19.0.0).
