Research On The Function Template Engine Based On Grain Grain Emergency Dispatching System

With the development of Internet technology, the application of Web B/S architecture has gradually replaced the traditional C/S application architecture, its function and demand is gradually complicated, the existing development model has been unable to meet the rapidly increasing business needs. For front-end developers, each set of management systems need to be developed separately, there is no uniform standard, code maintenance and transfer difficulties; the existing structure output to the browser on the server side to render the page, with the increase of the complexity and the amount of pageviews,will affect server performance.With the development of emergency grain visualization tracing and dynamic scheduling system, aiming at the existing template engine and development technology research and integration, the development of a JavaScript based template engine. The engine only needs the server to transfer the data according to the rules, so that it can automatically generate the visual pages related to business logic. First, this paper analyzes the technical features of the current development mode and problems of component reusability and scalability of the design consideration, main function, visual template engine architecture,modules and components, developed a set of JavaScript visual template engine, through the "data configuration" to "visualization", realize the research target, and for the development of visual tracking and emergency grain dynamic scheduling decision system, simplify and standardize the system development process, shorten the development time.In this paper, the development of a visual template engine is a highly modular and modular, the system has a code, scalability, and can meet the needs of different business logic template engine. The template engine will be the page rendering process on the client, the server only need to transfer lightweight JSON format data, slowing the server pressure. For server-side developers,as long as the format in accordance with the provisions of data transmission, can automatically construct visual page, the liberation of the front-end developer productivity development, so that it can focus more on the general assembly,improve development efficiency, and make the project more easy to maintain.
