vopono VS scraper

Vopono (https://github.com/jamesmcm/vopono):

"vopono is a tool to run applications through VPN tunnels via temporary network namespaces. This allows you to run only a handful of applications through different VPNs simultaneously, whilst keeping your main connection as normal.

vopono includes built-in killswitches for both Wireguard and OpenVPN."

I think for now on Linux you (still!) have to use external application to do the splitting. Such is vopono

I use vopono to manage it for me with Mullvad though.

you might want to check out vopono, i've gotten it working with firefox and its nice

I highly recommend using something like vopono with this on Linux that runs only the target application (e.g. Transmission) in a network namespace in the VPN and only forwards the specified ports and only allows traffic via the VPN.

This is why I use vopono - you can run just the torrent client in the VPN on its own and the killswitch keeps it safe.

You can find the option in the settings of windows and android apps. Unfortunately, it's Still not available for Linux. As a workaround for Linux, you can use vopono, which has OpenVPN support for Proton. Or just manually add routing table entries :)

I wrote vopono, I use it all the time for quickly spinning up browsers through different VPNs for checking geographical restrictions, etc.

Store the scrape progress (to-be-scraped / in-progress / scraped / in-error URLs) in a database shared by all participants and scrape in parallel with as many machines as the db load permits. Got a connection timeout / IP is blocked on one machine ? Update the scrape status for the corresponding URL and let another machine retry it. https://github.com/get-set-fetch/scraper (written in typescript) follows this idea. Using Terraform from a simple config file you can adjust the number of scraper instances to be deployed in cloud at startup and during the scraping process. In benchmarks a PostgreSQL server running on a DigitalOcean vm with 4vCPU, 8GB memory allows for ~2000 URLs to be scraped per second (synthetic data, no external traffic). From my own experience this is almost never the bottleneck. Obeying robots.txt crawl-delay will surely put you under this limit. Disclaimer: I'm the npm package author.

Written in typescript https://github.com/get-set-fetch/scraper stores scraped content directly in a database (sqlite, mysql, postgresql). Each URL represents a Resource. You can implement your own IResourceStorage and define the exact db columns you need.

You can use https://github.com/get-set-fetch/scraper with a custom plugin based on the mozilla/readability as detailed in https://getsetfetch.org/node/custom-plugins.html (extracting news article content). I think it's a close match to your use case.

I'm currently implementing concurrency conditions at project/proxy/domain/session level in https://github.com/get-set-fetch/scraper . On each level you can define the maximum number of requests and the delay between two consecutive requests.

If you're familiar with nodejs give https://github.com/get-set-fetch/scraper a try. Scraped content can be stored in sqlite, mysql or postgresql. It also supports puppeteer, playwright, cheerio or jsdom for the actual content extraction. No scheduler though.

I'm using this exact strategy to scrape content directly from DOM using APIs like document.querySelectorAll. You can use the same code in both headless browser clients like Puppeteer or Playwright and DOM clients like cheerio or jsdom (assuming you have a wrapper over document API). Depending on the way a web page was fetched (opened in a browser tab or fetched via nodejs http/https requests), ExtractHtmlContentPlugin, ExtractUrlsPlugin use different DOM wrappers (native, cheerio, jsdom) to scrape the content.

https://github.com/get-set-fetch/scraper - I've been working (intermittently :) ) on a nodejs or browser extension scraper for the last 3 years, see the other projects under the get-set-fetch umbrella. Putting a lot more effort lately as I really want to do those Alexa top 1 million analysis like top js libraries, certificate authorities and so on. A few weeks back I've posted on Show:HN as you can do basic/intermediate? scraping with it.

Not capable of handling 1 mil+ pages as it still limited to puppeteer or playwright. Working on adding cheerio/jsdom support right now.
