I don't want to restart a flame war but after choosing NodeJS for some projects based on specific modules not available in other languages (e.g: bitcore*) I am moving away or leaving it for very specific tasks. The code we wrote more than one year ago making an SQL transaction in 8 statements with async is difficult to understand and have some implicit stuff that you need to take into account. The other problem is not having a multithreading environment (in the official release) because you may want to respond to new tasks instead of blocking the event loop. I have seen timeouts because of this. Even if the recommendation is to do simple tasks, you can't enforce this when using hundreds of third party modules.
