# 动态记录

**动态记录**（dynamic record）是指其唯一身份标识不是顺序索引或命名变体，而是在 `meta` 字段中声明的任意键值对集合的内容文件。Intlayer 将在运行时使用这些字段作为选择器，从而可以定位 CMS 记录、用户特定文案或任何在构建时未知其键的内容。

## 声明动态记录

```ts fileName="product-copy.abc.content.ts" contentDeclarationFormat={["typescript", "esm", "commonjs"]}
import { t, type Dictionary } from "intlayer";

const dictionary = {
  key: "product-copy",
  meta: {
    id: "prod_abc",
    userId: "user_123",
  },
  content: {
    name: t({ en: "Widget Pro", fr: "Widget Pro" }),
    description: t({ en: "The best widget.", fr: "Le meilleur widget." }),
  },
} satisfies Dictionary;

export default dictionary;
```

```ts fileName="product-copy.abcd.content.ts" contentDeclarationFormat={["typescript", "esm", "commonjs"]}
import { t, type Dictionary } from "intlayer";

const dictionary = {
  key: "product-copy",
  meta: {
    id: "prod_abcd",
    userId: "user_123",
  },
  content: {
    name: t({ en: "Widget Lite", fr: "Widget Lite" }),
    description: t({ en: "A lighter option.", fr: "Une option plus légère." }),
  },
} satisfies Dictionary;

export default dictionary;
```

## 使用动态记录

选择器中所有的 `meta` 字段都是**必填**的。省略任何字段都将返回 `null` 并导致 TypeScript 报错。

    });

    if (content) {
      document.body.innerHTML = `<p>${content.description}</p>`;
    }

### 使用显式语言环境

```tsx
const content = useIntlayer("product-copy", {
  id: "prod_abc",
  userId: "user_123",
  locale: "zh",
});
```

### 缺少 meta 字段 — 编译时错误

```ts
// 类型错误：缺少 `userId`
const content = useIntlayer("product-copy", { id: "prod_abc" });
```

## 加载模式 (loading mode)

动态记录通常采用延迟加载方式。在字典中设置 `importMode` 来控制此行为：

```ts contentDeclarationFormat={["typescript", "esm", "commonjs"]}
const dictionary = {
  key: "product-copy",
  importMode: "fetch", // 或 "dynamic"
  meta: { id: "prod_abc", userId: "user_123" },
  content: { … },
} satisfies Dictionary;

export default dictionary;
```

关于 `static`、`dynamic` 和 `fetch` 模式的详细信息，请参阅[分包优化](https://github.com/aymericzip/intlayer/blob/main/docs/docs/zh/bundle_optimization.md)。

## 典型使用场景

- 在 CMS 中管理的单件商品营销文案
- 用户特定或账户特定的内容
- 在运行时通过不透明 ID 标识的任何内容
