How to optimize code reuse in Vue development

In Vue development, code reuse is a very important issue. When we encounter repeated logic or interfaces during development, if we can encapsulate them into reusable components or instructions, it will not only simplify the development process, but also improve the maintainability and readability of the code. This article will introduce some methods and techniques to optimize code reuse issues in Vue development.

1. Encapsulate reusable components

1. Abstract public logic or UI components: In development, we often encounter some public logic or UI components, such as forms Input boxes, date pickers, etc. At this time, we can encapsulate it into reusable components and separate the logic and UI through the single responsibility principle to make the components more versatile.
2. Use slots: Slots are a mechanism in Vue for distributing content to components. When we need to insert different content into a component, we can use slots. By encapsulating slots in components, components can be made more flexible and reusable.
3. Use mixin to mix in: mixin is a way to reuse component options in Vue. Code reuse can be achieved by defining some common logic and methods in mixins, and then mixing them in using the mixins option in the component.

2. Reasonable use of vuex for status management

1. Save public data in vuex: During development, some public data such as user login status, shopping The number of cars, etc. needs to be shared among multiple components. At this time, we can save these data in the state of vuex, and then obtain and update the data through getters and mutations to achieve unified management and reuse of data.
2. Use auxiliary functions: vuex provides some auxiliary functions, such as mapState, mapGetter, mapMutation, etc., which can simplify the use of state, getter and mutation. By using these helper functions, we can reduce duplication of code and make the code more concise and readable.

3. Write reusable instructions

1. Encapsulate common operations: During development, we often encounter some common operations, such as clicking, scrolling, Drag and drop etc. If these operations can be encapsulated into reusable instructions, they can be used directly when needed to avoid repeated code writing.
2. Use modifiers: The Vue directive provides some modifiers to modify the behavior of the directive according to specific needs. By using modifiers, instructions can be made more flexible and reusable.

4. Use third-party libraries for code reuse

1. Use third-party component libraries: In Vue development, there are many excellent third-party component libraries, such as ElementUI , Ant Design Vue, etc. These component libraries provide a wealth of UI components and commonly used functions, which can help us quickly develop and reuse code.
2. Use third-party plug-ins: In addition to third-party component libraries, there are also some third-party plug-ins that can help us solve code reuse problems. For example, Vue Router can help us manage routing, and Vue Axios can help us send Ajax requests. These plug-ins can improve code reusability and maintainability.

To sum up, optimizing code reuse issues in Vue development can include encapsulating reusable components, rationally using vuex for state management, writing reusable instructions, and using third-party libraries. Start with code reuse and other aspects. Through reasonable encapsulation and reuse, we can improve development efficiency, reduce duplicate code, and make the code clearer and maintainable. I hope this article can help everyone with code reuse issues in Vue development.
