Conditional Content / Condition in Intlayer

How Condition Works

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

Copy code

Copy the code to the clipboard

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;

To utilize conditional content in Next.js Client Components, retrieve it via the useIntlayer hook. Here's an example:

**/*.tsx

Copy code

Copy the code to the clipboard

"use client";

import type { FC } from "react";
import { useIntlayer } from "next-intlayer";

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

return (
  <div>
    <p>{myCondition(true)}</p>
    <p>{myCondition(false)}</p>
  </div>
);
};

export default ConditionalComponent;

To utilize conditional content in Vue components, retrieve it via the useIntlayer hook. Here's an example:

**/*.vue

Copy code

Copy the code to the clipboard

<script setup lang="ts">import { useIntlayer } from "vue-intlayer";const { myCondition } = useIntlayer("my_key");</script><template><div>  <p>{{ myCondition(true) }}</p>  <p>{{ myCondition(false) }}</p></div></template>

To utilize conditional content in Svelte components, retrieve it via the useIntlayer hook. The store is accessed with $. Here's an example:

**/*.svelte

Copy code

Copy the code to the clipboard

<script lang="ts">import { useIntlayer } from "svelte-intlayer";const content = useIntlayer("my_key");</script><div><p>{$content.myCondition(true)}</p><p>{$content.myCondition(false)}</p></div>

To utilize conditional content in Preact components, retrieve it via the useIntlayer hook. Here's an example:

**/*.tsx

Copy code

Copy the code to the clipboard

import type { FC } from "preact";
import { useIntlayer } from "preact-intlayer";

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

return (
  <div>
    <p>{myCondition(true)}</p>
    <p>{myCondition(false)}</p>
  </div>
);
};

export default ConditionalComponent;

To utilize conditional content in SolidJS components, retrieve it via the useIntlayer hook. Here's an example:

**/*.tsx

Copy code

Copy the code to the clipboard

import type { Component } from "solid-js";
import { useIntlayer } from "solid-intlayer";

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

return (
  <div>
    <p>{myCondition(true)}</p>
    <p>{myCondition(false)}</p>
  </div>
);
};

export default ConditionalComponent;

To utilize conditional content in Angular components, retrieve it via the useIntlayer hook. Here's an example:

app.component.ts

Copy code

Copy the code to the clipboard

import { Component } from "@angular/core";import { useIntlayer } from "angular-intlayer";@Component({selector: "app-conditional",template: `  <div>    <p>{{ content().myCondition(true) }}</p>    <p>{{ content().myCondition(false) }}</p>  </div>`,})export class ConditionalComponent {content = useIntlayer("my_key");}

To utilize conditional content with vanilla-intlayer, retrieve it via the useIntlayer hook. Here's an example:

**/*.ts

Copy code

Copy the code to the clipboard

import { installIntlayer, useIntlayer } from "vanilla-intlayer";

installIntlayer();

const content = useIntlayer("my_key").onChange((newContent) => {
document.getElementById("true-content")!.textContent =
  newContent.myCondition(true);
document.getElementById("false-content")!.textContent =
  newContent.myCondition(false);
});

// Initial render
document.getElementById("true-content")!.textContent =
content.myCondition(true);
document.getElementById("false-content")!.textContent =
content.myCondition(false);

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.

**/*.content.ts

Copy code

Copy the code to the clipboard

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;

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

Copy code

Copy the code to the clipboard

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;

To utilize conditional content in Next.js Client Components, retrieve it via the useIntlayer hook. Here's an example:

**/*.tsx

Copy code

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

return (
  <div>
    <p>{myCondition(true)}</p>
    <p>{myCondition(false)}</p>
  </div>
);
};

export default ConditionalComponent;
