Where is the Vue code generally placed?

Vue code is generally placed in components or in separate JavaScript files. In Vue, each page is usually composed of one or more components, and each component can contain several code blocks, including HTML templates, JavaScript code and CSS styles.

In Vue, we can use Single-file Components to create components. A single-file component usually includes a .vue file, which includes the following three parts:

1. Template part (template): This is the HTML structure of the component, which is used to define the styling and rendering method of the component. .
2. Script part (script): This is the JavaScript code of the component, including the definition of the Vue instance, the component's data, calculated properties, methods, life cycle hooks, etc.
3. Style part (style): This is the CSS style of the component, introduced through the style tag in the template, or written in a separate css file and imported through import in the script.

In single-file components, we can encapsulate the relevant code of each component in a file to facilitate management and maintenance. At the same time, Vue also provides some basic components and plug-ins, which we can install and reference through the npm package manager to speed up the development process and improve code quality.

In addition to single-file components, we can also put the Vue code in a separate JavaScript file and then reference it through the script tag in the HTML page. This method is suitable for writing small applications or pages that do not need to be split into components.

In general, Vue code can be placed in components or in separate JavaScript files. Writing as a single-file component can organize the code more efficiently and improve the readability and maintainability of the code. .
