Deploying Vue applications to production environments requires optimization of performance, stability and increased loading speed. 1. Use Vue CLI or Vite to build production versions, generate dist directory and set the correct environment variables; 2. If you use Vue Router's history mode, you need to configure the server to fallback to index.html; 3. Deploy the dist directory to Nginx/Apache, Netlify/Vercel or combine CDN acceleration; 4. Enable Gzip compression and browser caching policies to optimize loading; 5. Implement lazy loading components, introduce UI libraries on demand, enable HTTPS, prevent XSS attacks, add CSP headers, and restrict third-party SDK domain whitelists to enhance security.

Deploying a Vue application to a production environment is the core of optimizing performance, ensuring stability and improving loading speed. Vue itself is a framework-level tool, but when it is actually launched, it also needs to consider many aspects such as construction configuration, resource management, and security policies.

Build a production version using Vue CLI or Vite

Most Vue projects are built using Vue CLI or more modern Vite. Running npm run build (or vite build ) will generate a dist directory containing static resources and HTML files, which can be deployed directly to the server.

What should be noted is:

• Make sure that the correct environment variables are set before building, such as the API address to the production address.
• If Vue Router's history mode is used, the backend server needs to configure fallback to index.html.
• By default, code compression, Tree Shaking and resource optimization will be performed when building.

Vite is faster in the development stage and is suitable for new projects; Vue CLI is more suitable for existing projects or when more plug-ins are needed.

Deploy to a static server or CDN

After the build is completed, the most common deployment method is to upload the dist directory to a static hosting service, for example:

• Nginx/Apache : Local server deployment, flexible and controllable.
• Netlify / Vercel / Firebase Hosting : Zero configuration is online, automatic CI/CD.
• CDN acceleration : Such as Cloudflare and Alibaba Cloud CDN, it can significantly increase global access speed.

If your project is larger, it is recommended to enable Gzip compression and use the browser caching strategy to reduce duplicate downloads. In addition, it is also a common practice to place static resources such as pictures on CDN separately.

Performance optimization and security settings

Don't forget to make some basic optimizations before going online:

• Lazy loading components : asynchronous loading through routing to reduce the volume of the first screen.
• Introduce UI libraries on demand : For example, use the unplugin-vue-components plug-in to avoid the full introduction of Element Plus or Ant Design.
• Turn on HTTPS : This is a basic requirement for modern websites.
• Prevent XSS attacks : Do not use v-html to render user input content at will.
• Add CSP header : Enhance security and limit script sources.

If a third-party statistics code or SDK is used in the project, you should also check whether it is necessary to restrict the domain name whitelist.

Basically that's it. Building Vue production applications is not complicated, but it is easy to ignore details, such as routing mode, HTTPS settings, and cache control. A little attention can avoid many online problems.
