Techniques required for front-end development:

Skill 1: Draw prototypes and realize renderings

Excellent front-end Developers must be proficient in a prototype design tool and be able to draw ideas into prototypes through the tool. At the same time, the visual draft of the design can be expressed through page code. For example, the most popular and convenient prototyping tool Mockplus, the long-standing Axure, etc. If we can complete these two contents, we can initially enter the ranks of page front-end practitioners, but does this mean that we are qualified for page development work? No, it’s just the beginning!

Skill 2: Communication with designers and project participation

Communication is very important in all walks of life. As a front-end developer, the most important "customers" you come into contact with "That's the project designer. The designer creates a visual draft based on the prototype drawing. During this process, the front-end developer needs to discuss with the designer the implementation of certain effects, such as the impact on the rendering efficiency of low-end browsers and whether it can be achieved through CSS3 to make the structure clearer. Whether it is possible to find a balance between visual effects and code implementation. Front-end developers are responsible for the stability and rendering efficiency of the developed pages. In many cases, the project schedule requires that design and front-end development be carried out simultaneously. In this case, it is necessary to participate in project communication as much as possible.

Skill 3: Build a good page structure

In front-end development, writing the page structure is like laying the foundation when building a house. The quality of the structure will directly affect Code quality, JS development, back-end development and future page expansion, adjustment and iteration. When you get the design draft, don't rush to start work, observe and think more. First analyze the layout, divide the framework, then plan the structure and write code.

Skill 4: Beautiful Code

As web project functions become more and more complex, the direct consequence is that the size of the code becomes very large. How to carry out collaborative development and code maintenance is a question that needs to be considered from the beginning of front-end development. In this case, you need to consider improvement, unified planning, and develop a good code development habit. For example: reasonable use of tags, good comments, clear code structure, accurate use of CSS, etc. Beautiful code and clear structure can reduce communication costs for downstream development and collaborative development.

Skill Five: Ensuring Efficiency

As the first step in project development, front-end developers must have an understanding: complete it as early as possible to strive for more progress in the subsequent progress of the project. Much time. "If you want to do your job well, you must first sharpen your tools." In addition to practical experience and the formation of coding habits that can help us improve efficiency, if we want to improve our ability to control the progress of our own development, we also need to learn to use auxiliary tools to help improve page development. Efficiency, such as using Less or Sass can help us expand and organize CSS, greatly improving the efficiency of writing CSS and increasing maintainability. Do some digging and you'll be sure to find the tool that's most suitable for you.

Skill 6: Optimization for the server

Page development also needs to understand the optimization of the server to minimize the burden on the server. For example, CSS sprite is a typical example of reducing the number of server requests, and the class name is obfuscated and compressed to avoid the redundancy of too long names; base64 is applied to reduce the number of requests and other measures. These are the results of comprehensive trade-offs and require overall optimization in all aspects. Because when the number of page views reaches a certain order of magnitude, even a small optimization will achieve considerable results, otherwise small problems will bring big disasters.

Skill 7: Never stop learning

This is an era of rapid development and an era full of opportunities. The advent of the HTML5 era is accompanied by the rise of the mobile Internet. It creates greater opportunities, and there are too many things worth learning and discovering. As a developer, staying at the forefront of technology is always the best way to stay competitive. As the saying goes, "Only by building a strong foundation can success come naturally." Let’s share the words of Apple CEO’s speech at Stanford: “Stay Hungry, Stay Foolish”.
