unplugin-auto-import的基础用法

地址：https://github.com/unplugin/unplugin-auto-import

按需自动导入 Vite、Webpack、Rspack、Rollup 和 esbuild 的 API。具有 TypeScript 支持。由拔出电源供电。

安装：

npm i -D unplugin-auto-import

vite.config.ts配置：

// vite.config.ts
import AutoImport from 'unplugin-auto-import/vite'

export default defineConfig({
  plugins: [
    AutoImport({ /* options */ }),
  ],
})

AutoImport详细配置：

AutoImport({
  // targets to transform
  include: [
    /\.[tj]sx?$/, // .ts, .tsx, .js, .jsx
    /\.vue$/,
    /\.vue\?vue/, // .vue
    /\.md$/, // .md
  ],

  // global imports to register
  imports: [
    // presets
    'vue',
    'vue-router',
    // custom
    {
      '@vueuse/core': [
        // named imports
        'useMouse', // import { useMouse } from '@vueuse/core',
        // alias
        ['useFetch', 'useMyFetch'], // import { useFetch as useMyFetch } from '@vueuse/core',
      ],
      'axios': [
        // default imports
        ['default', 'axios'], // import { default as axios } from 'axios',
      ],
      '[package-name]': [
        '[import-names]',
        // alias
        ['[from]', '[alias]'],
      ],
    },
    // example type import
    {
      from: 'vue-router',
      imports: ['RouteLocationRaw'],
      type: true,
    },
  ],

  // Array of strings of regexes that contains imports meant to be filtered out.
  ignore: [
    'useMouse',
    'useFetch'
  ],

  // Enable auto import by filename for default module exports under directories
  defaultExportByFilename: false,

  // Auto import for module exports under directories
  // by default it only scan one level of modules under the directory
  dirs: [
    // './hooks',
    // './composables' // only root modules
    // './composables/**', // all nested modules
    // ...
  ],

  // Filepath to generate corresponding .d.ts file.
  // Defaults to './auto-imports.d.ts' when `typescript` is installed locally.
  // Set `false` to disable.
  dts: './auto-imports.d.ts',

  // Array of strings of regexes that contains imports meant to be ignored during
  // the declaration file generation. You may find this useful when you need to provide
  // a custom signature for a function.
  ignoreDts: [
    'ignoredFunction',
    /^ignore_/
  ],

  // Auto import inside Vue template
  // see https://github.com/unjs/unimport/pull/15 and https://github.com/unjs/unimport/pull/72
  vueTemplate: false,

  // Custom resolvers, compatible with `unplugin-vue-components`
  // see https://github.com/antfu/unplugin-auto-import/pull/23/
  resolvers: [
    /* ... */
  ],

  // Inject the imports at the end of other imports
  injectAtEnd: true,

  // Generate corresponding .eslintrc-auto-import.json file.
  // eslint globals Docs - https://eslint.org/docs/user-guide/configuring/language-options#specifying-globals
  eslintrc: {
    enabled: false, // Default `false`
    filepath: './.eslintrc-auto-import.json', // Default `./.eslintrc-auto-import.json`
    globalsPropValue: true, // Default `true`, (true | false | 'readonly' | 'readable' | 'writable' | 'writeable')
  },
})

tsconfig.app.json添加：

  "include": [略, "auto-imports.d.ts"]

不添加的话VsCode中的.vue用到的会报错。

重启后会在根目录生成auto-imports.d.ts
