Vue development skills: improve code quality and development efficiency

Vue is a popular JavaScript framework that is widely used for building user interfaces. It is easy to learn, efficient and flexible, so it is favored by developers.

However, in the actual development process, we may encounter some problems, such as low code quality and low development efficiency. This article will share with you some Vue development skills to help you improve code quality and development efficiency.

1. Component-based development
Vue is a component-based framework, so during the development process, we should split the UI into multiple small components for easy reuse and maintenance. Each component should focus on a specific function and follow the "single responsibility principle".

In component development, we can use Vue's built-in instructions and components to implement functions. Try to avoid using a lot of JavaScript code and keep components simple and maintainable.

2. Reasonable use of computed properties and listeners
In Vue, we can use computed properties and listeners to handle data changes. Computed properties are cached based on responsive dependencies. When the dependent data changes, the computed properties will be recalculated. The listener can observe changes in data and perform corresponding operations.

When using computed properties and listeners, we should follow the following principles:

• Try to use computed properties to handle the complex logic of data and bind them to templates for convenience Reuse and maintain.
• Use listeners instead of computed properties when you need to perform asynchronous operations when data changes.
• Avoid asynchronous operations in computed properties or listeners, which may cause performance issues.

3. Reasonable use of instructions and plug-ins
Vue provides a wealth of instructions and plug-ins that can help us achieve various functions. When using directives and plug-ins, we should choose based on actual needs and follow the following principles:

• Try to use Vue’s built-in directives and components instead of custom directives, because built-in directives have better performance and maintainability.
• When custom directives are required, you should ensure that they are well named and documented to make them easier for other developers to use and understand.
• When you need to use plug-ins, you should choose plug-ins that are well maintained and widely used, and avoid using immature or outdated plug-ins.

4. Reasonable use of Vuex and Vue Router
Vuex is Vue’s state management tool, which can help us manage the state of the application. Vue Router is Vue's routing management tool that can help us implement single-page applications.

When using Vuex and Vue Router, we should follow the following principles:

• Reasonably divide modules and namespaces to facilitate management and maintenance of status.
• Use appropriate computed properties and listeners to handle state changes.
• Try to avoid modifying the state directly in the component, but modify the state by submitting mutations.

5. Reasonable use of tools and third-party libraries
In Vue development, we can use various tools and third-party libraries to improve development efficiency and code quality. When using these tools and libraries, we should follow the following principles:

• Use appropriate development tools, such as Vue Devtools and editor plug-ins, to improve development efficiency and debugging capabilities.
• Use appropriate testing tools for unit testing and end-to-end testing to ensure code quality and stability.
• Use appropriate build tools and optimization methods, such as Webpack and code splitting techniques, to improve the performance and loading speed of your application.
• Use appropriate third-party libraries, such as axios and lodash, to provide better functionality and auxiliary tools.

By rationally using the above techniques, we can improve the code quality and development efficiency of Vue development. I hope this article can be helpful to everyone and be applied in actual development.
