Let’s talk about how to better understand Vue’s project structure

Vue is a very excellent JavaScript framework. Its emergence has brought great convenience to front-end development and reduced the workload of many front-end developers. However, for some novice developers, Vue's project structure often makes them confused and difficult to understand. Next, let's talk about how to better understand Vue's project structure.

Vue's project structure is divided into two categories, one is single-file component development, and the other is general component development.

The single file component structure consists of three parts, namely <template>, <script> and <style> . These three parts are required. The <template> part defines the HTML code structure of the current component, the <script> part defines the JavaScript code logic of the current component and the components it introduces, and the <style> defines the current component's CSS styles. The structure of this component is very clear, and the template, logic, and style are separated, making it easy to develop.

General Vue components are divided into two parts, namely JS and HTML/CSS. JS defines the JavaScript logic of the current suite and the components it introduces, while HTML/CSS defines the HTML code structure and CSS style of the current component. Although this component structure is not as clear as the single-file component structure, it may be easier for some beginners to understand.

The core part of the Vue project structure is the components. Communication and calling between components are very important, which is also a major advantage of the Vue framework. In addition, it also includes routing, state management, API, etc.

Routing is the most fundamental component of single-page application development for Vue. Routing includes the component-level definition and routing configuration required by Vue.

State management is an important part of managing different states in an application. State management in Vue is usually implemented using Vuex. Vuex includes a state tree, state change events, state change submission, and asynchronous state change mechanisms, which can ensure the correct operation of the application.

API is a way for the application to interact with the server interface. Generally speaking, APIs are customized by backend developers based on the needs of the application. APIs in Vue are usually implemented using axios. axios can implement asynchronous requests and return Promise objects, which greatly improves development efficiency.

The structure of the Vue project structure is not fixed. Developers can customize it according to their own needs, but it is best to keep the structure clear. Only by further understanding the structure of the Vue project can we develop Vue better.
