How to split the web front-end

With the rapid development of the Internet, Web front-end technology has become more and more mature, and more and more companies have begun to focus on Web front-end development, which has also led to an increasing demand for Web front-end developers. However, the technologies involved in Web front-end development are relatively complex. How can we better develop Web front-end? In this article, we will introduce how to split the web front-end development work for more efficient development.

1. The benefits of splitting the Web front-end

The Web front-end is a huge development field, including HTML, CSS, JavaScript, page performance optimization, browser compatibility and many other aspects. If it is not split, it may bring the following problems to the development work:

1. The code is huge. It is difficult for web front-end developers to separate concerns when writing code, resulting in a huge amount of code.

2. Collaborative development is inconvenient. If multiple developers develop together, the developers need to spend a lot of time merging code and resolving conflicts.

3. Poor maintainability. If you put all the code in one file, then if you need to make modifications, you need to find the location of the code that needs to be modified. Such modifications are very inefficient.

2. Steps for Web front-end splitting

1. Split HTML and CSS.

Normally, HTML and CSS are closely related. However, proper splitting of HTML and CSS can separate concerns, improve code readability and make development more efficient.

For example, we can use elements such as navigation bars, tables, buttons, etc. as separate CSS files, which not only reduces the size of the CSS file, but also facilitates subsequent modifications.

2. Split the business logic (JS code).

Try to isolate the front-end business logic from page elements, such as subdividing system functions such as page turning, search, sorting, and confirmation into separate functions and components to facilitate subsequent maintenance and upgrades. At the same time, it also better realizes the separate development of front-end and back-end. During the implementation process, the use of modular development can facilitate the organization and invocation of code, and can also facilitate combination and expansion with other modules.

3. Split the code into functional modules.

The advantages of splitting according to functional modules are as follows: firstly, splitting according to functional modules can make the code more readable and maintainable; secondly, if you need to change or add the code of a functional module, you can do a block of code Making modifications without modifying all the code improves the overall maintainability of the code and reduces risks.

4. Organize the common code and pour it into separate files.

In the development of Web front-end, some common codes will be used by multiple pages, such as header, bottom, menu, etc. At this time, the common part of the code can be extracted to generate a separate file. And just introduce it in the HTML page you need to use.

3. Precautions for Web front-end splitting

1. Avoid excessive splitting.

Although splitting can improve development efficiency, it cannot be split too much. Excessive splitting will increase the number of files and increase the loading time of the page. Another bad effect is that it may cause your code to become extremely loose, reducing readability and maintainability.

2. Give priority to functional modules.

When splitting code, we should first give priority to splitting it based on the functional relationship between codes, and try to ensure readability and maintainability.

3. Standardize code style.

After splitting the code, it should also be standardized according to the company's code style to facilitate subsequent code maintenance and development. At the same time, pay attention to code comments to facilitate yourself and others to maintain the code.

Summary:

In Web front-end development, code splitting is a complex process, but formulating a splitting plan and adopting reasonable methods can not only improve the readability and Maintainability can also improve development efficiency. Try to adopt a modular approach, split the code according to functional modules, follow the company's code specifications, and annotate the code clearly, so that you can write high-quality Web front-end code.
