Perform simple reverse-proxying in HAProxy. #reverse-proxy #proxy #haproxy #proxypass

A more complete example (with rewriting cookie domains/paths) can be found at http://blog.haproxy.com/2014/04/28/howto-write-apache-proxypass-rules-in-haproxy/

We will try something roughly equivalent to the following ProxyPass directives in Apache2:

ServerName www.example.com
...
ProxyPass        /foo/  http://foo.local
ProxyPassReverse /foo/  http://foo.local

In haproxy.cfg we define a backend, say foo, to reverse-proxy to foo.local backend server.

Starving the Event Loop with Microtasks

Starving the Event Loop with microtasks

"What's the Event Loop?"

Sparked from this twitter conversation when talking about doing fast async rendering of declarative UIs in Preact

These examples show how it's possible to starve the main event loop with microtasks (because the microtask queue is emptied at the end of every item in the event loop queue). Note that these are contrived examples, but can be reflective of situations where Promises are incorrectly expected to yield to the event loop "because they're async".

  • setTimeout-only.js is there to form a baseline
