Detailed explanation of the optimization project structure of Vue file unreasonable organizational structure

The organizational structure of Vue files is unreasonable: How to optimize project structure

In modern front-end development, it is often used as a popular framework to build complex single-page applications.

As the project scales, maintainability and readability of the code become particularly important. However, many developers are prone to making common mistakes when organizing Vue file structures, which makes it difficult to maintain and expand the project.

Frequently Asked Questions

1. All components are in the same folder

In many small projects, developers tend to put all Vue components in onecomponentsin folder.

• For example:

src/
  components/
    
    
    
    
    ... (Other components)

Although this approach may seem concise when the project is smaller, it becomes very cumbersome when the number of components increases, especially when there are many similar components between different modules or pages.

Solution: Divide components by module or function

To enhance the readability and maintainability of the code, components can be organized according to their functional modules.

• For example:

src/
  modules/
    user/
      components/
        
        
    admin/
      components/
        
        
    common/
      components/
        
        
        
        

Through this modular approach, we can quickly find components of relevant functions, while also facilitating team collaboration.

2. Complex file naming rules

Another common problem is that file naming is inconsistent or not descriptive. For example, the file is named, etc. This naming method is not only difficult to understand, but also confuses new members when looking for components.

Solution: Naming rules for using specifications

It is recommended to set a unified naming rule.

For example, it can be usedPascalCaseorkebab-case, in the file name, and also contains the component's function description.

• For example:

src/
  components/
    
    
    

In this way, the file name can intuitively reflect the functionality of the component, reducing the cost of understanding.

3. Mix different types of files

As the project develops, a large number of JavaScript files, style files, and template files may appear to be mixed together. This situation can make the process of finding and modifying code more complicated.

Solution: Use Single File Component (SFC)

Vue's Single File Components (SFC) allows us to<template>, <script>, and<style>Three parts are placed in the same.vueThe document ensures the concentration of relevant content.

At the same time, we can manage styles and test files separately by creating subdirectories.

• For example:

src/
  components/
    
    
    styles/
      
      
    tests/
      
      

In this way, using SFC can improve cohesion between the various parts and facilitate later maintenance.

4. Use magic strings and unorganized constants

Another reason why code is poorly readable is the use of magic strings.

• For example:

export default {
  data() {
    return {
      role: 'admin'
    }
  },
  methods: {
    changeRole() {
       = 'user';  // Magic string    }
  }
}

Magic strings make code maintenance complicated. If you want to modify the character value, you need to find and modify it manually in multiple places.

Solution: Use constants

Constants can be used to organize these string values ​​for ease of use in multiple components, so that you can just modify them in one place.

• For example:

const USER_ROLES = {
  ADMIN: 'admin',
  USER: 'user'
}

export default {
  data() {
    return {
      role: USER_ROLES.ADMIN
    }
  },
  methods: {
    changeRole() {
       = USER_ROLES.USER;  // Use constants    }
  }
}

In this way, it will be easy to add or modify character information in the future.

5. No reasonable state management

With the increase of Vue components, communication and state management between components have become more and more complicated. Sometimes developers may rely on global variables or cumbersome props and event passes to manage state, which makes it difficult to understand the code.

Solution: Use Vuex or Composition API

• I recommend using Vuex (state management library) to centrally manage state, or using the Composition API provided by Vue 3+ to make state more organized and easier to maintain.

// Use Vuex status managementimport Vue from 'vue';
import Vuex from 'vuex';

(Vuex);

export default new ({
  state: {
    userRole: USER_ROLES.ADMIN
  },
  mutations: {
    SET_USER_ROLE(state, role) {
       = role;
    }
  },
  actions: {
    changeRole({ commit }, role) {
      commit('SET_USER_ROLE', role);
    }
  }
});

By centrally managing state, implicit dependencies between components can be reduced, making business logic clearer.

Summarize

During Vue development, a reasonable file organization structure is the prerequisite for ensuring code quality and maintainability.

We explore several common problems and provide corresponding solutions.

Through modular components, standardized naming, reasonable division of files, use constants and centralized management of state, developers can create clearer and more efficient Vue projects.

The above is personal experience. I hope you can give you a reference and I hope you can support me more.
