Setting a proxy IP in SingleFile

[rohit103]

Hello, is there a way to setup a proxy IP in SingleFile? I will greatly appreciate any pointers on this. Thanks!

You mean with SingleFile CLI?

Yes, in our use case we want to open the single file puppeteer instance with proxy IP that needs credentials for authentication.

If you're using Chrome under the hood, you should be able to use --browser-args to pass the proxy address. Here's an example:

./single-file --browser-args=["--proxy-server=http://217.196.238.154"] https://www.example.com

FYI, I found the public proxy here: https://scrapingant.com/free-proxies/

Thanks for the response, this would work for proxies that do not need credentials. For the proxies that need authentication, in our vanilla puppeteer instance we could do page.authenticate({...}), so was wondering if that was possible in singleFile to pass proxy credentials also.

Thank you for the info. I confirm the current code does not offer a way to pass data to page.authenticate. Meanwhile, maybe this technique would work? https://blog.apify.com/4-ways-to-authenticate-a-proxy-in-puppeteer-with-headless-chrome-in-2022/#4-setting-the-proxy-authorization-header

The last version I just published on NPM (v1.0.27) includes these new options:

• --http-proxy-server (e.g. "http://123.231.123.231")
• --http-proxy-username (e.g. "root")
• --http-proxy-password (e.g. "p4$$w0rd")

thank you for adding the option to pass proxy, will give it a test and let you know about the results.

Upgraded single file cli to latest version and tried using the new proxy options and it seems to work. Thank you
