Answer to the question: Where to put the js files in vue scaffolding

The front-end framework Vue.js has become the first choice of many developers. In the Vue.js project, it is very important to use a good scaffolding, which not only saves development time, but also improves the maintainability and scalability of the code. However, in the process of using Vue.js scaffolding, a common question is: where to place the JS files?

The first thing you need to understand is: In the Vue.js project, there are two main types of JavaScript files: Vue components (.vue files) and independent JavaScript files (.js files).

The Vue component is a self-contained unit that contains HTML, CSS, and JavaScript code. Vue.js scaffolding handles components in the form of .vue files, which are composed of templates, scripts, and styles for Vue components. This file is generally located in the src/components folder. Each Vue component folder should contain:

[name].vue

where [name] can be replaced with the name of the component. For example, Header.vue, Footer.vue, etc. Each .vue file should contain the following content:

<template>
  <!-- HTML代码 -->
</template>

<script>
  export default{
    // JavaScript代码
  };
</script>

<style>
  /* CSS代码 */
</style>

In Vue components, DOM manipulation should be avoided as much as possible, and all JavaScript code should be limited to the scope of the current component.

The Vue component defines HTML content through the

In addition to Vue components, JavaScript files are also an important part of the Vue.js project. These files include global scripts, plug-ins, tool libraries, etc. These files can interact with Vue components and provide global access.

So, where should independent JavaScript files be placed? Normally, Vue.js scaffolding places independent JavaScript files in the src/utils folder, including tool functions, global APIs, data requests, etc. For example, there may be the following files in the utils folder:

utils
├── api.js
├── request.js
└── tools.js

Among them, api.js and request.js are usually used to encapsulate data request-related codes, and tools.js contains some common tool functions. These files can be imported by Vue components or other JavaScript files through the ES6 import syntax.

In addition to being placed in the utils folder, independent JavaScript files can also be placed in the src/assets folder. Some global style files and image resources are usually placed here. However, it should be noted that the JavaScript code in these files should try to avoid manipulating the DOM.

In the Vue.js project, developers can freely choose the location of JavaScript files according to their own needs and project structure. To facilitate management and maintenance, it is recommended to use folders to classify different types of files, which is conducive to code reuse and maintenance.

To summarize, in a Vue.js scaffolding project, Vue components should be placed in the src/components folder, and independent JavaScript files can be placed in the src/utils folder or src/assets folder. For these JavaScript files, you should use the ES6 import syntax to reference them to avoid directly modifying the DOM.
