What environment is needed to execute the vue program?

As Vue (a popular JavaScript framework) continues to become more popular in web application development, many developers want to understand the environment required to execute Vue programs to ensure that their applications can run properly. In this article, we will take a closer look at the environment and tools required to execute Vue programs.

Vue’s environment requirements

Before executing the Vue program, you need to ensure that you have met the following requirements:

1. Node.js

Node.js is a JavaScript runtime environment, similar to the JavaScript interpreter in the browser. It enables developers to run JavaScript code on the server side. Vue applications require the Node.js runtime environment in order to develop and test the application on your local machine. If you have not installed Node.js, please go to the official site https://nodejs.org/en/ to download the installer, follow the prompts to install and add it to the PATH environment variable.

2. npm

npm is a Node.js package manager used to install and manage dependencies in applications. Before you start creating your Vue application, make sure you have successfully installed Node.js as the Node.js installer will also automatically install npm. You can check if you have npm installed by running the following command in the terminal:

$ npm -v

If you don't receive any version number, try reinstalling Node.js and restarting the terminal.

3. Vue CLI

Vue CLI is an official Vue.js command line tool for quickly creating Vue applications and managing their development. You can use it to create Vue projects and run the project locally for development and testing. To install the Vue CLI, run the following command in the terminal:

$ npm install -g @vue/cli

4. Editor

When creating a Vue application, you will need to use a text editor to write your code . Here are some of the most popular editors using Vue:

• Visual Studio Code
• Sublime Text
• Atom
• WebStorm

The above editors can be used with the Vue CLI and are configured for Vue, making it easier to create and providing code highlighting, smart code completion and other functions.

5. Browser

Vue applications will eventually run in a browser, so you need a modern web browser to test your application. Here are some of the most popular browsers using Vue:

• Google Chrome
• Mozilla Firefox
• Safari
• Microsoft Edge

Vue’s development and testing tools

After meeting the above environmental requirements, we also need to use appropriate development and testing tools to ensure the quality and reliability of Vue applications. The following are several tools commonly used in Vue development and testing:

1. Vue Devtools

Vue Devtools is the official debugging tool for Vue applications, available in the browser Do debugging and inspect Vue components. This tool allows you to browse the Vue instance tree, perform function traceback, inspect data changes, view event lists, debug styles and layouts, and more. Find and fix problems in your Vue applications faster with Vue Devtools.

2. Jest

Jest is a modern JavaScript testing framework that can be used to write unit and end-to-end tests for Vue applications. You can use Jest to write and run test suites and provide reliable and efficient test coverage to your applications. Many Vue developers use Jest to ensure their applications run consistently.

3. Cypress

Cypress is a popular end-to-end testing framework for testing JavaScript web applications. Using Cypress, you can write and run automated tests and check your application's performance and stability across all devices and browsers. It provides tools such as live reloading, fast secondary testing, and timers to greatly improve the efficiency and quality of the testing process.

Summary

In this article, we discussed Vue’s development environment requirements and tools to ensure you can successfully create Vue applications from scratch. We explore the software and tools you need to install and provide several popular and useful development and testing tools. If you want to learn Vue and use it to build high-quality web applications, this article will be a very useful resource.
