It is not recommended to directly modify the native code when separating WordPress front and back ends, and it is more suitable for "improved separation". Use the REST API to obtain data and build a user interface using the front-end framework. Identify which functions are called through the API, which are retained on the backend, and which can be cancelled. The Headless WordPress mode allows for a more thorough separation, but it is more cost-effective and difficult to develop. Pay attention to security and performance, optimize API response speed and cache, and optimize WordPress itself. Gradually migrate functions and use version control tools to manage code.

WordPress’s front-end separation: It’s not just separation

Many friends asked me how to separate WordPress from the front and back ends, and I think this can improve performance, enhance security, and even make the website cooler. Yes, these benefits do exist, but things are not that simple. It's like trying to screw nuts with a screwdriver. Although it can be barely screwed on, the efficiency and effect are definitely not as good as using a suitable wrench.

Let’s talk about the conclusion first: It is not realistic to directly transform WordPress native code into a front-end and back-end separate architecture, and it is likely that the gain will not be worth the loss. WordPress’s architecture determines that it is more suitable for a “modified” separation rather than a complete “push-down and start over”.

Basics Review: Don't Forget What WordPress is

WordPress is essentially a PHP-driven CMS that blends database, template engine and application logic. If you want to separate the front and back ends, it means you have to clarify the mess clearly. This is not as simple as placing PHP code and front-end code in different folders. It involves a series of issues such as the design of data interfaces, the construction of APIs, the selection of front-end frameworks, etc.

Core concept: REST API is key, but not all

WordPress has built-in REST API since version 4.7, which provides the basis for front-end and back-end separation. You can use this API to obtain WordPress data, and then use React, Vue, Angular and other front-end frameworks to build your user interface.

But this is just the first step. WordPress themes and plug-in mechanisms still exist, and they will still be coupled with your front-end code. You have to carefully identify which functions need to be called through the API, which functions can be retained on the backend, and which functions can be cut off.

 <code class="javascript">// 一個(gè)簡(jiǎn)單的React 組件，獲取WordPress 文章列表import React, { useState, useEffect } from 'react'; const PostList = () => { const [posts, setPosts] = useState([]); useEffect(() => { fetch('/wp-json/wp/v2/posts') .then(res => res.json()) .then(data => setPosts(data)); }, []); return ( <ul> {posts.map(post => ( <li key="{post.id}"> <a href="%7Bpost.link%7D">{post.title.rendered}</a> </li> ))} </ul> ); }; export default PostList;</code>

This code shows how to use React components to get a list of articles from the WordPress REST API. It seems simple, but in actual applications, you may need to deal with more complex needs such as paging, searching, filtering, etc., which requires you to have a deep understanding of WordPress API and front-end frameworks.

Advanced Usage: The Charm and Challenge of Headless WordPress

If you want to implement front-end and back-end separation more thoroughly, consider using Headless WordPress. This is an architectural model, which only retains WordPress as the content management system, responsible for the storage and management of content, and the front-end is completely independent and can freely choose any technology stack. This can give you the greatest flexibility, but it also means higher development costs and maintenance difficulties. You need to build the entire front-end application yourself and be responsible for all front-end logic and user experience.

Common Errors and Debugging Tips: Don't Forget Safety and Performance

Security is crucial in the process of separation of front and back ends. You need to seriously consider the authentication and authorization mechanism of the API to prevent malicious attacks. In addition, performance is also a key factor, and you need to optimize the API's response speed and use the appropriate caching strategy. Don’t forget that WordPress itself also needs to be optimized, otherwise if you separate the front-end but the back-end is stuck in PPT, wouldn’t it be a waste of work?

Performance optimization and best practices: small steps and iterative optimization

Don't try to get it in one step. Start with simple functions and gradually migrate WordPress's functions to new front-end applications. You can make a simple page first, display only the article list, and then gradually add other features. Remember, the readability and maintainability of the code are very important, don't write code that only you can understand. Using version control tools such as Git can help you manage your code better and rollbacks easily.

In short, the front-end separation of WordPress is not a simple technical issue, but an architectural design issue. It requires you to have an in-depth understanding of WordPress, REST API and front-end frameworks, and you also need to weigh various factors and choose the solution that suits you best. Don’t be fascinated by the so-called “front and back end separation”, and choose the most appropriate solution based on the actual situation. Step by step and take steady steps are the key to success.
