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
- 安装 @types/node
npm i @types/node -D
- 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
},
})
- 使用
比如,修改 App.vue:
import HelloWorld from '@/components/HelloWorld.vue'
配置环境变量
- 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 = /
- 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;
}
- 环境类型定义
在 types\index.d.ts 文件里新增对 Recordable 和 ViteEnv 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"
]
- 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/, "")
}
}
},
}
})
