# Conditional Content / Condition in Intlayer

## How Condition Works

In Intlayer, conditional content is achieved through the `cond` function, which maps specific conditions (typically boolean values) to their corresponding content. This approach enables you to dynamically select content based on a given condition. When integrated with React Intlayer or Next Intlayer, the appropriate content is automatically chosen according to the condition provided at runtime.

## Setting Up Conditional Content

To set up conditional content in your Intlayer project, create a content module that includes your conditional definitions. Below are examples in various formats.

```typescript fileName="**/*.content.ts" contentDeclarationFormat="typescript"
import { cond, type Dictionary } from "intlayer";

const myConditionalContent = {
  key: "my_key",
  content: {
    myCondition: cond({
      true: "my content when it's true",
      false: "my content when it's false",
      fallback: "my content when the condition fails", // Optional
    }),
  },
} satisfies Dictionary;

export default myConditionalContent;
```

```javascript fileName="**/*.content.mjs" contentDeclarationFormat="esm"
import { cond } from "intlayer";

/** @type {import('intlayer').Dictionary} */
const myConditionalContent = {
  key: "my_key",
  content: {
    myCondition: cond({
      true: "my content when it's true",
      false: "my content when it's false",
      fallback: "my content when the condition fails", // Optional
    }),
  },
};

export default myConditionalContent;
```

```javascript fileName="**/*.content.cjs" contentDeclarationFormat="commonjs"
const { cond } = require("intlayer");

/** @type {import('intlayer').Dictionary} */
const myConditionalContent = {
  key: "my_key",
  content: {
    myCondition: cond({
      true: "my content when it's true",
      false: "my content when it's false",
      fallback: "my content when the condition fails", // Optional
    }),
  },
};

module.exports = myConditionalContent;
```

```json5 fileName="**/*.content.json" contentDeclarationFormat="json"
{
  "$schema": "https://intlayer.org/schema.json",
  "key": "my_key",
  "content": {
    "myCondition": {
      "nodeType": "condition",
      "condition": {
        "true": "my content when it's true",
        "false": "my content when it's false",
        "fallback": "my content when the condition fails", // Optional
      },
    },
  },
}
```

> If no fallback is declared, the last key declared will be taken as a fallback if the condition is not validated.

## Using Conditional Content with React Intlayer

To utilize conditional content within a React component, import and use the `useIntlayer` hook from the `react-intlayer` package. This hook fetches the content for the specified key and allows you to pass in a condition to select the appropriate output.

```tsx fileName="**/*.tsx" codeFormat="typescript"
import type { FC } from "react";
import { useIntlayer } from "react-intlayer";

const ConditionalComponent: FC = () => {
  const { myCondition } = useIntlayer("my_key");

  return (
    <div>
      <p>
        {
          /* Output: my content when it's true */
          myCondition(true)
        }
      </p>
      <p>
        {
          /* Output: my content when it's false */
          myCondition(false)
        }
      </p>
      <p>
        {
          /* Output: my content when the condition fails */
          myCondition("")
        }
      </p>
      <p>
        {
          /* Output: my content when the condition fails */
          myCondition(undefined)
        }
      </p>
    </div>
  );
};

export default ConditionalComponent;
```

```javascript fileName="**/*.mjx" codeFormat="esm"
import { useIntlayer } from "react-intlayer";

const ConditionalComponent = () => {
  const { myCondition } = useIntlayer("my_key");

  return (
    <div>
      <p>
        {
          /* Output: my content when it's true */
          myCondition(true)
        }
      </p>
      <p>
        {
          /* Output: my content when it's false */
          myCondition(false)
        }
      </p>
      <p>
        {
          /* Output: my content when the condition fails */
          myCondition("")
        }
      </p>
      <p>
        {
          /* Output: my content when the condition fails */
          myCondition(undefined)
        }
      </p>
    </div>
  );
};

export default ConditionalComponent;
```

```javascript fileName="**/*.cjs" codeFormat="commonjs"
const { useIntlayer } = require("react-intlayer");

const ConditionalComponent = () => {
  const { myCondition } = useIntlayer("my_key");

  return (
    <div>
      <p>
        {
          /* Output: my content when it's true */
          myCondition(true)
        }
      </p>
      <p>
        {
          /* Output: my content when it's false */
          myCondition(false)
        }
      </p>
      <p>
        {
          /* Output: my content when the condition fails */
          myCondition("")
        }
      </p>
      <p>
        {
          /* Output: my content when the condition fails */
          myCondition(undefined)
        }
      </p>
    </div>
  );
};

module.exports = ConditionalComponent;
```
