# Markdown / Rich Text Content

Intlayer supports rich text content defined using Markdown syntax. This allows you to easily write and maintain content with rich formatting, such as blogs, articles, and more.

## Declaring Markdown Content

You can declare Markdown content using the `md` function or simply as a string (if it contains Markdown syntax).

<Tabs>
  <Tab label="Manual Wrapping" value="manual-wrapping">
    Use the `md` function to explicitly declare Markdown content. This is useful if you want to ensure a string is treated as Markdown even if it doesn't contain obvious syntax.

    ```typescript fileName="markdownDictionary.content.ts"
    import { md, type Dictionary } from "intlayer";

    const markdownDictionary = {
      key: "app",
      content: {
        myMarkdownContent: md("## My title \n\nLorem Ipsum"),
      },
    } satisfies Dictionary;

    export default markdownDictionary;
    ```

  </Tab>
  <Tab label="Automatic Detection" value="automatic-detection">
    If the string contains common Markdown indicators (like headers, lists, links, etc.), Intlayer will automatically transform it.

    ```typescript fileName="markdownDictionary.content.ts"
    export default {
      key: "app",
      contentAutoTransformation: true, // Enable automatic detection of Markdown content - Can be set globally in intlayer.config.ts
      content: {
        myMarkdownContent: "## My title \n\nLorem Ipsum",
      },
    };
    ```

  </Tab>
  <Tab label="External Files" value="external-files">
    Import `.md` files directly using the `file` function.

    ```typescript fileName="markdownDictionary.content.ts"
    import { md, file, t } from "intlayer";

    export default {
      key: "app",
      content: {
        content: t({
          en: md(file("./myMarkdown.en.md")),
          fr: md(file("./myMarkdown.fr.md")),
        }),
      },
    };
    ```

  </Tab>
</Tabs>

## Part 2: Rendering Markdown

Rendering can be handled automatically by Intlayer's content system or manually using specialized tools.

### 1. Automatic Rendering (using `useIntlayer`)

When you access content via `useIntlayer`, Markdown nodes are already prepared for rendering.

<Tabs group="framework">
  <Tab label="React / Next.js" value="react">
    Markdown nodes can be rendered directly as JSX.

    ```tsx fileName="App.tsx"
    import { useIntlayer } from "react-intlayer";

    const AppContent = () => {
      const { myMarkdownContent } = useIntlayer("app");
      return <div>{myMarkdownContent}</div>;
    };
    ```

    You can also provide local overrides for specific nodes using the `.use()` method:

    ```tsx
    {myMarkdownContent.use({
      h1: ({ children }) => <h1 className="text-3xl font-bold">{children}</h1>,
    })}
    ```

  </Tab>
  <Tab label="Vue" value="vue">
    In Vue, Markdown content can be rendered using the `component` built-in or directly as a node.

    ```vue fileName="App.vue"
    <script setup>
    import { useIntlayer } from "vue-intlayer";
    const { myMarkdownContent } = useIntlayer("app");
    </script>

    <template>
      <component :is="myMarkdownContent" />
    </template>
    ```

  </Tab>
  <Tab label="Svelte" value="svelte">
    Svelte renders Markdown as an HTML string by default. Use `{@html}` to render it.

    ```svelte
    <script lang="ts">
    import { useIntlayer } from "svelte-intlayer";
    const content = useIntlayer("app");
    </script>

    {@html $content.myMarkdownContent}
    ```

  </Tab>
  <Tab label="Preact" value="preact">
    Preact supports Markdown nodes directly in the JSX.

    ```tsx fileName="App.tsx"
    import { useIntlayer } from "preact-intlayer";

    const AppContent = () => {
      const { myMarkdownContent } = useIntlayer("app");
      return <div>{myMarkdownContent}</div>;
    };
    ```

  </Tab>
  <Tab label="Solid" value="solid">
    Solid supports Markdown nodes directly in the JSX.

    ```tsx fileName="App.tsx"
    import { useIntlayer } from "solid-intlayer";

    const AppContent = () => {
      const { myMarkdownContent } = useIntlayer("app");
      return <div>{myMarkdownContent}</div>;
    };
    ```

  </Tab>
  <Tab label="Angular" value="angular">
    Angular uses the `[innerHTML]` directive to render Markdown content.

    ```typescript fileName="app.component.ts"
    import { Component } from "@angular/core";
    import { useIntlayer } from "angular-intlayer";

    @Component({
      selector: "app-root",
      template: `<div [innerHTML]="content().myMarkdownContent"></div>`,
    })
    export class AppComponent {
      content = useIntlayer("app");
    }
    ```

    You can also provide local overrides for specific nodes using the `.use()` method:

    ```typescript
    content().myMarkdownContent.use({
      h1: { class: "text-3xl font-bold" },
    })
    ```

  </Tab>
</Tabs>

### 2. Manual Rendering & Advanced Tools

If you need to render raw Markdown strings or have more control over the rendering process, use the following tools.

<Tabs group="framework">
  <Tab label="React / Next.js" value="react">
  
    #### `<MarkdownRenderer />` Component

    Render a Markdown string with specific options.

    ```tsx
    import { MarkdownRenderer } from "react-intlayer";

    <MarkdownRenderer forceBlock={true} tagfilter={true}>
      {"# My Title"}
    </MarkdownRenderer>
    ```

    #### `useMarkdownRenderer()` Hook

    Get a pre-configured renderer function.

    ```tsx
    import { useMarkdownRenderer } from "react-intlayer";

    const renderMarkdown = useMarkdownRenderer({
      forceBlock: true,
      components: { h1: (props) => <h1 {...props} className="custom" /> }
    });

    return renderMarkdown("# My Title");
    ```

    #### `renderMarkdown()` Utility
    Standalone utility for rendering outside of components.

    ```tsx
    import { renderMarkdown } from "react-intlayer";

    const jsx = renderMarkdown("# My Title", { forceBlock: true });
    ```

  </Tab>
  <Tab label="Vue" value="vue">

        return this.markdownService.renderMarkdown(markdown);
      }
    }
    ```

## Global Configuration with `MarkdownProvider`

You can configure Markdown rendering globally for your entire application. This avoids passing the same props to every renderer.

        tagfilter={true}
        components={{
          h1: ({ children }) => <h1 className="text-2xl font-bold">{children}</h1>,
          a: ({ href, children }) => <Link to={href}>{children}</Link>,
        }}

| Option                | Type        | Default | Description                                                                           |
| :-------------------- | :---------- | :------ | :------------------------------------------------------------------------------------ |
