Unable to catch 'econnreset'

Hi!

Currently all modern browsers support AbortController which can cancel running http request. And http-proxy can catch that and actually provides econnreset event for that case.

But seems like http-proxy-middleware doesn’t expose that to the consumer, list of events doesn’t contain onEconnreset.

Is there a workaround for that case or it might be considered as a bug?

@chimurai Yes, you right, it’s possible to override the whole proxyError handler!

ah, my bad.

Think you can use the onProxyReq option, which just exposes the http-proxy.on('proxyReq') event.

function onProxyReq(proxyReq, req, res) {
  // add custom header to request
  proxyReq.setHeader('x-added', 'foobar');
  // or log the req
}

You should be able to add listeners to proxyReq and req, like you pointed out earlier. https://github.com/http-party/node-http-proxy/commit/927357bedc42f2e3067c44c10ab9563be7d8b032#diff-6b475017a1a35b15c446d2edf40979f6R143
