express

问题 I am very new to Node.js and express. I am currently learning it by building my own services. I recently read about clusters. I understood what clusters do. What I am not able to understand is how to make use of clusters in a production application.

问题 I was searching the web and documentation for node.js express module and it seems there is no way to send data by parts. I have a file rendered not very fast and I want to send parts of it before everything is rendered. So here are my questions: Is there a method on response to send data by parts? What does response.end() ? If there is no way to send data by parts - what is the rationale behind? I would say it looks more blocking than non-blocking if that's true. Browser can load information
