Control proxy-chain's 'host' parameter from Apify's launchContext

[zuccon]

The host argument has been added to proxy-chain, for its listener to be bound to something else than 0.0.0.0.

However it's not possible to set this parameter while launching Puppeteer as it's not available in the launchContext.

Is it possible to add this option to the launchContext, or do you have any advice for launching Puppeteer with a customized proxy-chain instance which has this argument too?

Thanks!

Hello @zuccon !

Are you sure this is an issue for this package (apify/apify-client-js)? To me, this sounds like a thing from crawlee - there, we're using proxy-chain to create a local proxy server that authenticates with the target proxy server. I'll transfer this issue to crawlee and we can continue the discussion there.

As far as I understand - you want this "immediate" proxy server inside crawlee to only listen on a certain address / network interface, right?

Hi @barjin, thanks for answering.

As far as I understood the proxy-chain instance is instantiated in crawlee, however crawlee is instantiated by our call of Apify.launchPuppeteer(), with Apify being const Apify = require("apify");.

https://docs.apify.com/sdk/js/docs/1.3/api/apify#apifylaunchpuppeteerlaunchcontext

So in order for it to work, I believe this option needs to be propagated from proxy-chain, where it has been implemented first, through crawlee, to end up being exposed in Apify's launchContext so that we can change its default value.
I may be wrong though, not completely familiar with it yet.

yes, this is the goal
