Hardcoding IP addresses in configuration files should be avoided. It makes the configuration inflexible for other developers and can leak internal network information.

It's recommended to use environment variables for this kind of configuration. Vite has built-in support for .env files.

You can refactor this to use loadEnv:

1. In your .env or .env.development file, add:

   VITE_API_PROXY_TARGET=http://172.29.202.54:8080
   

2. Then, update vite.config.js to load and use this variable:

   import { defineConfig, loadEnv } from 'vite';
   
   export default defineConfig(({ mode }) => {
     const env = loadEnv(mode, process.cwd(), '');
     return {
       // ... other config
       server: {
         proxy: {
           '/xingchen-api': {
             target: env.VITE_API_PROXY_TARGET,
             changeOrigin: true,
           },
           // ...
         },
       },
       // ...
     };
   });

This makes the proxy target easily configurable without changing the code.
