body is capped at 10MB with followRedirects=true

[gigafied]

follow-redirects defaults maxBodyLength to 10MB.

http-proxy does not expose a way to set any options for this module, what's worse is that the error is actually swallowed silently and the request aborted...

Have the same issue. In the past (around v1.11) it worked fine, it seems the follow-redirects default settings have been changed. Would be useful if we could set the maxBodyLength in the proxy options. At the moment it's not really usable if you're redirecting requests with a body bigger than 10MB.

The error is catchable with the error handler:

proxy.on('error', (err) => console.log(err));

Below the stack trace:

Error: Request body larger than maxBodyLength limit

Created a PR for that #1441.

Note, as a workaround, you can always set those values before calling http-proxy

import FollowRedirects from "follow-redirects";
FollowRedirects.maxRedirects = 10;
FollowRedirects.maxBodyLength = 1024 * 1024 * 1024 * 1024;
