![]() Finally, we close the browser instance.īy using the download event, we can wait for all downloads to complete with Puppeteer in a reliable and efficient way. ![]() We then navigate to the page that initiates the download and wait for all downloads to complete using the waitForDownload method. ![]() We add a listener to the download event to log when a download is completed. We then set the download behavior for the page to allow downloads and specify the download path. In this code, we first create a new browser instance using Puppeteer and a new page. send ( 'tDownloadBehavior', ) await page. You should find Puppeteer executes successfully, provided proper Chrome flags are used.Const puppeteer = require ( 'puppeteer' ) const browser = await puppeteer. Chrome will write into /tmp instead.Īdd your JavaScript to your container with a COPY instruction. disable-dev-shm-usage – This flag is necessary to avoid running into issues with Docker’s default low shared memory space of 64MB.If you’re uncomfortable with this, you’ll need to manually configure working Chrome sandboxing, which is a more involved process. It’s vital you ensure your Docker containers are strongly isolated from your host. Using these flags could allow malicious web content to escape the browser process and compromise the host. no-sandbox and disable-setuid-sandbox – These disable Chrome’s sandboxing, a step which is required when running as the root user (the default in a Docker container).Setting this flag explicitly instructs Chrome not to try and use GPU-based rendering. disable-gpu – The GPU isn’t usually available inside a Docker container, unless you’ve specially configured the host. ![]()
