# Dynamic Records

A **dynamic record** is a content file whose identity is not a sequential index or a named variant, but an arbitrary set of key-value pairs declared in a `meta` field. Intlayer uses those fields as the selector at runtime, making it possible to address CMS records, user-specific copy, or any content whose keys are not known at build time.

## Declaring dynamic records

```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;
```

## Consuming dynamic records

All `meta` fields are **required** in the selector. Omitting any field returns `null` and is a TypeScript error.

### With explicit locale

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

### Missing meta field — compile-time error

```ts
// Type error: `userId` is missing
const content = useIntlayer("product-copy", { id: "prod_abc" });
```

## Loading mode

Dynamic records are typically loaded lazily. Set `importMode` on the dictionary to control this:

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

export default dictionary;
```

See [bundle optimisation](https://github.com/aymericzip/intlayer/blob/main/docs/docs/en-GB/bundle_optimization.md) for details on `static`, `dynamic`, and `fetch` modes.

## Typical use-cases

- Per-product marketing copy managed in a CMS
- User-specific or account-specific content
- Any content keyed by an opaque runtime ID
