How to create a custom Markdown rules

[ArvindhMangoleap]

I am trying to build a parser that converts markdown into WhatsApp compatible format

For example,

Whatsapp uses underscore ( _ ) on both sides of the string for Italic instead of start ( * )

WhatsApp _Italic_
Regular Markdown *Italic*

WhatsApp *Bold*
Regular Markdown **Bold**

I can use custom extensions to overwrite bold, italics etc.

Is there a way to disable all other render methods like list, paragraph, table, etc? Because I don't need them.

you can create your own tokenizer and return undefined to prevent marked from creating a token.

const tokenizer = {
  heading() {
    // return nothing/undefined to prevent tokenization
  }
};

marked.use({ tokenizer });
