科协 2024 聊天室 Web 前端

部署爬坑记录,供 Web 开发参考

开发环境和生产环境是不一样的,部署之前一定要在本机测试好,以免出现问题。

下面列出几个发现的问题:

  1. vite.config.ts在生产环境需要配置 base 路径字段
export default defineConfig({
  base: './',
  //...
})
  1. 前后端路径一定要做区分,比如后端路径加上 /api/ 前缀 本项目大部分都做了区分,但是,经调试,ws 链接路径没加 /api/ 前缀,导致连接出错

  2. ip 硬编码问题,经排查,ws url 使用硬编码 ip 和协议名,导致连接出错

const socketURL = `ws://10.34.38.118/chat/${username}/${touxiang}`; 

应该改为

var socketURL = new URL(`/api/chat/${username}/${touxiang}`, window.location.href);
socketURL.protocol = socketURL.protocol.replace(location.protocol, location.protocol === 'https:' ? 'wss' : 'ws');
const socket = new WebSocket(socketURL); 

建议

部署之前先使用 caddy 来测试

npm run build-only # 编译

以下是 Caddyfile , BACKEND_URLBACKEND_HOST 可自行修改,前者为后端 url, 如 http://127.0.0.1:8080 , 后者为要传递给后端的 host , 如 xxx.kexie.space

:80 {
        root * ./dist
        file_server
        handle_path /api/* {
              reverse_proxy "{$BACKEND_URL}" {
                 header_up host "{$BACKEND_HOST}"
              }
        }
}

This template should help get you started developing with Vue 3 in Vite.

Recommended IDE Setup

VSCode + Volar (and disable Vetur).

Type Support for .vue Imports in TS

TypeScript cannot handle type information for .vue imports by default, so we replace the tsc CLI with vue-tsc for type checking. In editors, we need Volar to make the TypeScript language service aware of .vue types.

Customize configuration

See Vite Configuration Reference.

Project Setup

npm install

Compile and Hot-Reload for Development

npm run dev

Type-Check, Compile and Minify for Production

npm run build
