Add plugin

The way that you can add custom plugins to the mix, is by adding them before or after a built-in plugin.

Let's say we want to use the "remark-github-alerts" plugin. It must be added before or after a built-in remark plugin. Do the same with rehype plugins too. Let's say we want to add it after the built-in "remark-gfm" plugin.

import remarkGithubAlerts from "remark-github-alerts"

svelteInMarkdownPreprocess({
    onTransform: async (options, config) => {
        return await transformer(options, config, {
            builtInPlugins: {
                remarkGfm: {
                    plugins: {
                        after: remarkGithubAlerts,
                    },
                },
            },
        })
    },
})
