What's My Problem With Node.js?So you may have guessed by now, if you follow me on The Twitters, that I'm not the biggest fan of Node.js.
If programming is hard to get right, then distributed concurrent programming is - relatively speaking - impossible to get right. You will almost certainly get it wrong. And the more you do of it, the more wronger what it do be.
The secret to getting concurrency right is to do as little of it as you can get away with. Well-designed applications that achieve this tend to have small, isolated and very heavily tested islands of concurrency. Often they have signs on the shore warning travellers to "turn back, dangerous waters!", "beware of rabid dogs!", "danger: radiation!" and "Look out! Skeletor!" You know; stuff that tends to send right-minded folk who value their lives running in the opposite direction.
Node.js is a great big friendly sign that says "Come on in. Hot soup. Free Wi-Fi.", and it's left to salvage specialists like me to retrieve the broken wrecks.
So, yes, Node.js does make it easier to do distributed concurrency, in much the same way that a hammer makes it easier to drive nails into your head. And both are liable to leave you with a hell of a headache in the morning.
