Vite4+Typescript+Vue3+Pinia 从零搭建(3) - vite配置

项目代码同步至码云 weiz-vue3-template
关于vite的详细配置可查看 vite官方文档,本文简单介绍vite的常用配置。

初始内容

项目初建后,vite.config.ts 的默认内容如下:

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
})

配置别名

1. 安装 @types/node

npm i @types/node -D

2. 修改 vite.config.ts

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'

// 路径查找
const pathResolve = (dir: string): string => {
  return resolve(__dirname, ".", dir);
};

// 设置别名,还可以添加其他路径
const alias: Record<string, string> = {
  "@": pathResolve("src"),
  "@views": pathResolve("src/views"),
  "@store": pathResolve("src/store/modules")
};

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias
  },
})

3. 使用

比如,修改 App.vue:

import HelloWorld from '@/components/HelloWorld.vue'

配置环境变量

1. 新建env文件

根目录下新建 .env.env.development.env.production 三个文件。
.env 文件内新增内容:

# 本地运行端口号
VITE_PORT = 8686

.env.development 文件内新增内容:

# 本地环境
VITE_USER_NODE_ENV = development

# 公共基础路径
VITE_PUBLIC_PATH = /

.env.production 文件内新增内容:

# 线上环境
VITE_USER_NODE_ENV = production

# 公共基础路径
VITE_PUBLIC_PATH = /

2. 环境变量统一处理

根目录下新建 build 文件夹,其目录下新建 index.ts,内容如下:

// 环境变量处理方法
export function wrapperEnv(envConf: Recordable): ViteEnv {
  const ret: any = {};

  for (const envName of Object.keys(envConf)) {
    let realName = envConf[envName].replace(/\\n/g, "\n");
    realName = realName === "true" ? true : realName === "false" ? false : realName;
    if (envName === "VITE_PORT") realName = Number(realName);
    ret[envName] = realName;
    if (typeof realName === "string") {
      process.env[envName] = realName;
    } else if (typeof realName === "object") {
      process.env[envName] = JSON.stringify(realName);
    }
  }
  return ret;
}

3. 环境类型定义

types\index.d.ts 文件里新增对 RecordableViteEnv 的类型定义:

type Recordable<T = any> = Record<string, T>;

interface ViteEnv {
  VITE_USER_NODE_ENV: "development" | "production";
  VITE_PUBLIC_PATH: string;
  VITE_PORT: number;
}

修改 tsconfig.json 文件,将 build 文件夹内的文件包含进去:

"include": [ // 需要检测的文件
  "src/**/*.ts",
  "build/*.ts",
  "src/**/*.d.ts",
  "src/**/*.tsx",
  "src/**/*.vue",
  "mock/*.ts",
  "types/*.d.ts",
  "vite.config.ts"
],

同理,修改 tsconfig.node.json 文件:

"include": [
  "build/*.ts",
  "types/*.d.ts",
  "vite.config.ts"
]

4. 使用

修改 vite.config.ts

import { defineConfig, loadEnv, ConfigEnv, UserConfig } from "vite"
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'
import { wrapperEnv } from './build'

// 路径查找
const pathResolve = (dir: string): string => {
  return resolve(__dirname, ".", dir);
};

// 设置别名,还可以添加其他路径
const alias: Record<string, string> = {
  "@": pathResolve("src"),
  "@views": pathResolve("src/views"),
  "@store": pathResolve("src/store")
};

// https://vitejs.dev/config/
export default defineConfig(({ mode }: ConfigEnv): UserConfig => {
  const root = process.cwd()
  const env = loadEnv(mode, root)
  const viteEnv = wrapperEnv(env)

  return {
    base: viteEnv.VITE_PUBLIC_PATH,
    plugins: [vue()],
    resolve: {
      alias
    },
    server: {
      host: "0.0.0.0",
      port: viteEnv.VITE_PORT,
      https: false,
      open: true,
      // 本地跨域代理 https://cn.vitejs.dev/config/server-options.html#server-proxy
      proxy: {
        "^/api": {
          target: "http://192.168.1.4:8688",
          changeOrigin: true,
          rewrite: path => path.replace(/^\/api/, "")
        }
      }
    },
  }
})
