碩士 === 國立臺北科技大學 === 資訊工程系研究所 === 105 === The new concept is separate by front-end and back-end. The front-end part consists of front page and various of action interface. The back-end part consists of transfering of data. It makes web service very specific. The traditional HTTP server can only use one thread to activate one execution. If I/O needs to waiting, it will delay and waste the resources. Node.js needs to use a asynchronous method to improve I/O waiting problem. Node.ja is hard to develop on HTTP code. Many of HTTP code need to write by self. The Express module makes the coding simplified. It lets developers focus more on their logic code with much less distractions. We need to investigate how to incorporate Node.js with Express concept. First, we need to understand how Express concept works. It is repeating use module, and we use this module to form web services. Lastly, we use pressure tools to test these web services. It will presemt how Node.js peforms in massive execution.
