>Express > Limited extensibility, Eran felt strangled by the middleware (Connect) implementation, particularly when he needed multiple components to coordinate together [3]. I'm able to leverage the full power of javascript/node, which is fairly powerful. > Poor isolation of the server from the business logic which prevented the reuse of services for purposes like batching operations (you don't want to have to go through the Express middleware chain for an internal request) [3]. Yeah none of this makes sense. You're doing something wrong. Express doesn't limit you here. > Code instead of configuration, Express emphasized using code (imperative programming) instead using a more declarative model when wiring up middleware and defining routes [3]. And code is in fact more configurable and extensible which negates the first point made. >These developers tend to be spoiled with a wealth of tools like IDE's (with syntax highlighting and code completion), debuggers, VM monitoring tools, etc. Node.js does not have this sort of support. Vim supports a lot of that.
