Design And Implementation Of Image Sharing Application Based On Node.js

With the development of mobile Internet, Taking a photograph and sharing it in social platforms has become people’s habit. Many photo-sharing applications have also appeared at home and abroad, such as Instagram, Meitu XiuXiu and so on. Although photo applications at home and abroad are complex and many, they focus primarily on the picture itself, such as adding effects processing for a picture. All the photo applications concentrated their products on "Tools", while ignoring the social factors seriously. In order to improve the sociability of the photo-sharing application, this paper has designed and implemented a photo-sharing application which is combined with Wechat.The main task of this paper is to design and implement a Mobile Web system of photo-sharing application based on Node.js. This paper firstly analyzed requirements of the photo-sharing application, summarized the functional requirements and performance needs of the system. In order to take full advantage of mobile devices and Wechat platform, the system uses Wechat public number as the interface between users and it Secondly, based on the system design principle of mobile-side Web application, this paper designed overall the photo-sharing application, including system architecture, functional modules and development environment, its main function modules include user registration, photo uploading, cropping photos, customizing games’pictures and sharing custom games. Thirdly, according the MVC design pattern, this paper designed the photo-sharing application in detail, including database design of the model layer, defining the interface of the relevant business logic of the control layer and system UI design. In accordance with the detailed design of the system, this paper developed and implemented the photo-sharing application, and described the main technical points of the system in detail, including the implementation of system’s business logic, cropping pictures, gallery cascade layout, accessing to Wechat public number and system performance optimizing. Lastly, in order to ensure the stability of the system, the system’s functions have been tested completely.
