Example JS app Let's start with a dynamic page that generates its HTML via JavaScript: public/index. Its APIs make it possible to take a client-side app and prerender (or 'SSR') its markup. Puppeteer uses several defaults that can be customized through configurationįor example, to change the default cache directory Puppeteer uses to installīrowsers, you can add a. If you're in Node, Puppeteer is an easy way to work with headless Chrome. Include $HOME/.cache into the project's deployment.įor a version of Puppeteer without the browser installation, see Your project folder (see an example below) because not all hosting providers So each time you install / update puppeteer, it will download its specific chrome version. Heroku, you might need to reconfigure the location of the cache to be within Puppeteer includes its own chrome / chromium, that is guaranteed to work headless. The following is code for getting a handle to the background page of an extension whose source is located in. caution Extensions in Chrome/Chromium currently only work in non-headless mode and experimental Chrome headless mode. If you deploy a project using Puppeteer to a hosting provider, such as Render or Version: 20.2.0 Chrome Extensions Puppeteer can be used for testing Chrome Extensions. The browser is downloaded to the $HOME/.cache/puppeteer folderīy default (starting with Puppeteer v19.0.0). Another solution I tried was manually removing the HeadlessChrome substring from the userAgent in case the site was blocking it, but that didnt work either.When you install Puppeteer, it automatically downloads a recent version ofĬhrome for Testing (~170MB macOS, ~282MB Linux, ~280MB Windows) that is guaranteed to My research suggests that the browser is closing before the download completes possibly? Ive added a wait of about 15 seconds, which is much longer than it should need to download the file, but still not getting anything. Im able to run it with no problems while headless: false, but when headless:true, the file does not download.
Im running a script that logs into an authenticated session on a website and clicks a button to download an excel file.
