Summary
Development of computer hardware technology has brought a great variety of display terminals, the explosive growth of data is also presented to the user interface makes the increasingly complex interaction has become more diverse, under the impact of these changes, web attendant replacement, the speed change is astounding. The face of these problems, web development technology keep updated and to develop techniques and tools become increasingly diverse.
Based on this, the new technology will be part of this paper web in the field of research and practice them.
First, JavaScript is part of the new features and JavaScript development model to do a detailed study and elaboration. Because JavaScript to ECMAScrtpt specification allows for the sixth JavaScript has many new features that greatly enriched the development mode, it allows developers to accomplish more tasks with fewer lines of code development. Web system increasingly large, traditional JavaScript development methods can not meet the demand, there will also elaborate on JavaScript modular development.
Then node.js is a detailed study and elaboration. Node.js JavaScript language will appear with the server to break the shackles of the browser, it has a broader field of application.
Finally, the design and implementation of web chat system. Based on the above technology, which combines websocket and mongoDB database technology, the integrated use of these techniques and practice them, to look to the future development trend of web technologies.
Keywords : JavaScript; modular development; node.js
