Let’s update our script to line the trail. We can avoid the default download path by explicitly specifying the trail in our script. Finally, we are using the click() function to simulate the button click. Then we are opening up a replacement tab with the given URL. We are creating a replacement instance of Puppeteer. This may allow us to watch the automation in real-time.

The headless option is about to be false. We can use the subsequent script to automate the download process Finally, we’ll click on the download button. Then we’ll find the download button on the page. we’ll open up a URL during a new browser tab. In the first example, we’ll take a glance at an easy scenario where we automate a button click to download a picture. Downloading a picture by simulating button click We’ll undergo several practical examples and take a deep dive into Puppeteer’s APIs used for file download. That’s why this text is there to share a number of the ideas and tricks which will be used while working with Puppeteer. Unfortunately, these use cases aren’t well documented. You perhaps have to explicitly specify a download location, download multiple files at an equivalent time, and so on. You should find Puppeteer executes successfully, provided proper Chrome flags are used.In this article, we’ll discuss the way to efficiently download files with 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.
