In your Dockerfile, copy these files into the container and use npm ci to install Puppeteer. This will create a package.json and package-lock.json for you to use. You should find Puppeteer executes successfully, provided proper Chrome flags are used. Now run npm install puppeteer in your local working directory. 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. Since version 1.7.0 we publish the puppeteer-core package,a version of Puppeteer that doesn't download any browser by default. PUPPETEERPRODUCTfirefox npm install PUPPETEERPRODUCTfirefox yarn install javascript node. To skip the download, download into another path, or download a different browser, see Environment variables. Using these flags could allow malicious web content to escape the browser process and compromise the host. Run 'PUPPETEERPRODUCTfirefox npm install' or 'PUPPETEERPRODUCTfirefox yarn install' to download a supported Firefox browser binary. 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). To download a file with Puppeteer using headless mode, you can set the download behavior using the () method.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.const puppeteer = require ( 'puppeteer' ) const fs = require ( 'fs' ) const path = require ( 'path' ) require ( 'dotenv' ).
The code is for a very specific situation and therefore would need to be modified accordingly dependant on your requirements. The full code can be seen below, and the repo is available at. Requirements - For this you'll need a recent version of NodeJs (tested with version 14.14.0). This gave me a good excuse to try and automate the process as much as possible using puppeteer. 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. To learn more about the font and typography of the Puppeteer font, simply enter the text in the field below and click GENERATE.The online preview allows you to know the fonts without the need to download and install the font. I needed to download a video that was behind a login screen. Latest version Released: Project description pyppeteer Note: this is a continuation of the pyppeteer project.
