One browser (using an incognito page) per URL. Incognito page (see IncognitoBrowserContext) for each URL Shares everything (cookies, localStorage, etc.) between jobs. The default option is Cluster.CONCURRENCY_CONTEXT, but it is recommended to always specify which one you want to use. You can set it in the options when calling Cluster.launch. There are different concurrency models, which define how isolated each job is run. Provide types for input/output with TypeScript generics.Using a different puppeteer library (like puppeteer-core or puppeteer-firefox).Deep crawling the Google search results.
We then queue two jobs and wait for the cluster to finish. Then a task is defined which includes going to the URL and taking a screenshot. A cluster is created with 2 concurrent workers. The following is a typical example of using puppeteer-cluster. Npm install -save puppeteer-cluster Usage Install puppeteer (if you don't already have it installed): Progress view and monitoring statistics (see below).Different concurrency models to choose from (pages, contexts, browsers).Auto restarts the browser in case of a crash.Typings for input/output (via TypeScript Generics).Puppeteer Cluster takes care of reusing Chromium and restarting the browser in case of errors. This is helpful if you want to crawl multiple pages or run tests in parallel. This library spawns a pool of Chromium instances via Puppeteer and helps to keep track of jobs and errors. I am not sure that the code in my Docker file will work to install Chrome.Create a cluster of puppeteer workers. It worked during development, but for some reason it does not work in a Docker container. When we run the command "npm i puppeteer," I assumed I didn't need to install Chrome. I'm using the Puppeteer library for that, and in order for my conversion to work, I need to run Chromium (whether it is headless or not). I want to save the PDF file after converting the HTML content.
My backend is running inside a Docker container and is built with Nest Js. & apk add google-chrome-stable -no-cache -repository= \ & sh -c 'echo "deb stable main" > /etc/apk//google.list' \ This is my dockerfile code: FROM node:18-alpine As baseĮNV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true
