Install

You can install marked-alert using npm or yarn:

npm i marked-alert
# or
yarn add marked-alert

Usage

Once you've installed this extension, you can use it in your marked configuration. Here's an example of how to configure it:

Say we have the following file example.md:

# Example

> [!NOTE]
> Highlights information that users should take into account, even when skimming.

> [!TIP]
> Optional information to help a user be more successful.

> [!IMPORTANT]
> Crucial information necessary for users to succeed.

> [!WARNING]
> Critical content demanding immediate user attention due to potential risks.

> [!CAUTION]
> Negative potential consequences of an action.

And our module example.js looks as follows:

import { readFileSync } from 'node:fs'
import { Marked } from 'marked'
import markedAlert from 'marked-alert'

const html = new Marked()
  .use(markedAlert())
  .parse(readFileSync('example.md', 'utf8'))

console.log(html)

Now, running node example.js yields:

Options

The markedAlert extension accepts the following configuration options:

• className: A string representing a custom CSS class for the alerts.
• variants: An array of alert variants, where each variant is configured with a type, icon, and title class name. This allows you to create different alert types.

Default Alert Variants

The extension includes default alert variants:

• [!NOTE]: Highlights information that users should take into account, even when skimming.
• [!TIP]: Optional information to help a user be more successful.
• [!IMPORTANT]: Crucial information necessary for users to succeed.
• [!WARNING]: Critical content demanding immediate user attention due to potential risks.
• [!CAUTION]: Negative potential consequences of an action.

Each variant has an associated icon and title class name.

You can customize the default alert variants and add your own. Here's an example:

const options = {
  variants: [
    {
      type: 'danger',
      icon: '<i class="mr-2">🚨</i>',
      title: 'Oh snap!', // optional
      titleClassName: 'text-danger' // optional
    }
  ]
}
