+**生成基础文件**，后面要用到：
+
+```bash
+npx expo customize babel.config.js
+npx expo customize metro.config.js
+```
+
+## 配置eslint格式化
+
+可以使用快捷命令（推荐）：
+
+```bash
+pnpm dlx @antfu/eslint-config@latest
+```
+
+安装：
+
+```bash
+pnpm i -D eslint @antfu/eslint-config
+```
+
+新建 `eslint.config.mjs` 文件：
+
+```js
+import antfu from '@antfu/eslint-config'
+
+export default antfu({
+  stylistic: {
+    indent: 2, // 缩进为 2 个空格（可选 4 或 'tab'）
+    quotes: 'single', // 使用单引号（可选 'double'）
+  },
+  rules: {
+    'unused-imports/no-unused-imports': 'warn',
+    'unused-imports/no-unused-vars': 'warn',
+    '@typescript-eslint/no-use-before-define': 'off', // 关闭 TS 的“定义前使用”警告
+    'no-console': 'off', // 关闭 console 报错
+  },
+})
+```
+
+配置 vscode 模板，修改 `.vscode/settings.json` ：
+
+> 注意安装 eslint 插件
+
+```json
+{
+  // Disable the default formatter, use eslint instead
+  "prettier.enable": false,
+  "editor.formatOnSave": false,
+
+  // Auto fix
+  "editor.codeActionsOnSave": {
+    "source.fixAll.eslint": "explicit",
+    "source.organizeImports": "never"
+  },
+
+  // Silent the stylistic rules in you IDE, but still auto fix them
+  "eslint.rules.customizations": [
+    { "rule": "style/*", "severity": "off", "fixable": true },
+    { "rule": "format/*", "severity": "off", "fixable": true },
+    { "rule": "*-indent", "severity": "off", "fixable": true },
+    { "rule": "*-spacing", "severity": "off", "fixable": true },
+    { "rule": "*-spaces", "severity": "off", "fixable": true },
+    { "rule": "*-order", "severity": "off", "fixable": true },
+    { "rule": "*-dangle", "severity": "off", "fixable": true },
+    { "rule": "*-newline", "severity": "off", "fixable": true },
+    { "rule": "*quotes", "severity": "off", "fixable": true },
+    { "rule": "*semi", "severity": "off", "fixable": true }
+  ],
+
+  // Enable eslint for all supported languages
+  "eslint.validate": [
+    "javascript",
+    "javascriptreact",
+    "typescript",
+    "typescriptreact",
+    "vue",
+    "html",
+    "markdown",
+    "json",
+    "jsonc",
+    "yaml",
+    "toml",
+    "xml",
+    "gql",
+    "graphql",
+    "astro",
+    "svelte",
+    "css",
+    "less",
+    "scss",
+    "pcss",
+    "postcss"
+  ]
+}
+```
+
+## 配置深度链接
+
+作用：通过链接就可以跳转到该app。
+
+在 `app.json` 文件下进行配置：
+
+```json
+{
+  "expo": {
+    "scheme": "oneao"
+  }
+}
+```
+
+然后就可以通过这个配置 从别的应用或者浏览器跳转到你的app：
+
+```
+oneao://courses/react-native
+```
+
+## 定义 src 路径别名 @
+
+> 参考：https://docs.expo.dev/guides/typescript/
+
+修改 `tsconfig.json` 文件：
+
+```json
+{
+  "extends": "expo/tsconfig.base",
+  "compilerOptions": {
+    "baseUrl": "./",
+    "paths": {
+      "@/*": ["src/*"]
+    },
+    "strict": true
+  }
+}
+```
+
+安装 `module-resolver` ：
+
+```
+pnpm add -D babel-plugin-module-resolver
+```
+
+修改 `babel.config.js` ：
+
+```js
+module.exports = function (api) {
+  api.cache(true)
+  return {
+    presets: [
+      ['babel-preset-expo', { jsxImportSource: 'nativewind' }],
+      'nativewind/babel',
+    ],
+    plugins: [
+      [
+        'module-resolver',
+        {
+          root: ['./src'],
+          alias: {
+            '@': './src',
+          },
+        },
+      ],
+    ],
+  }
+}
+```
