How to use vue project after development

Vue is an open source, lightweight framework based on JavaScript for building single-page applications (SPA), componentized web development, and front-end development. Due to its flexibility, ease of learning, and ease of integration into existing projects, Vue has become one of the mainstream front-end frameworks for front-end development in recent years.

During the Vue project development process, some best practices need to be followed to ensure project maintainability, scalability and readability. In this article, we will introduce how to use the Vue project after development from aspects such as how to establish a Vue project, component establishment, status management and debugging.

Build a Vue project

1. Confirm the environment: Confirm whether Node.js and Vue-cli are installed in your development environment.

Node.js: It is a JavaScript running environment built on the Google Chrome kernel. Its function is to enable JavaScript to run on the server side.

Vue-cli: A single-page application generator based on webpack to quickly build a Vue-based project development environment.

2. Build project: Using Vue-cli is the easiest way to build and deploy Vue projects. Vue-cli includes a variety of quick creation templates for you to choose from, such as webpack templates, simple templates, browserify templates, etc. With a simple command line operation, you can create a Vue project in minutes.

Establishment of Components

Components are the core concept of Vue because they allow developers to build complex functionality and reuse code. In Vue, components have their own state, life cycle, and templates.

1. Component naming: In order to better combine components in Vue, we should use unique and descriptive component names. For components in large projects, it is a good practice to use namespaces to avoid naming conflicts.
2. Single file component: This is a recommended way of organizing components in Vue. It separates the three parts of the component - template, JavaScript and CSS - into a separate file for easy maintenance and debugging.

State management

State management is an important aspect in front-end development. Vuex is Vue's official state management library, helping teams better organize, share state, and manage state. The basic concept of Vuex is to store the application's state (the data in all Vue components) as a centralized, reactive state repository, making the component's state easier to manage and deliver.

1. State storage model: In Vuex, the state storage model is a responsive JavaScript object that contains all the states we want to store. By modifying it, we can achieve communication and communication with the Vue component. Shared status.
2. The core concept of Vuex:

• state: stores all the state data of the application and is a responsive JavaScript object.
• mutations: The type used to modify the state. It is a pure function (no side effects are allowed).
• actions: used to submit mutations and implement asynchronous operations. It is a function with a context object.
• getters: derive some new states by calculating the state

Debugging

Debugging is inevitable from Vue development. Here are some debugging tips that can Help developers quickly diagnose problems:

1. Use Vue developer tools: Vue official developer tools provide the function of debugging Vue applications on the browser. It can inspect component trees, states, events and routes, and also supports Vuex state inspection and modification. The tool is available on both Chrome and Firefox browsers.
2. Introducing auxiliary functions: Vue provides some hook functions and auxiliary functions to help us better debug the code during the development process. For example, we can use the Vue.$nextTick() function in the component's mounted() life cycle to wait for the DOM to be instantiated and completed before performing further operations, thereby avoiding problems caused by incomplete DOM operations.

Conclusion

Vue is one of the most popular front-end frameworks today. Due to its advantages in ease of learning, flexibility, adaptability and performance, Vue has become a popular choice for many enterprises. and developers' first choice. In Vue project development, following best practices can help improve development efficiency, improve code quality, and thus better manage projects. I hope this article will be helpful to developers who are new to Vue.
