n8n-nodes-md-to-whatsapp

Convert Markdown text into WhatsApp-compatible formatting directly inside n8n workflows.

What It Does

| Markdown Input | WhatsApp Output | | ------------------------ | -------------------------- | | **bold** / __bold__ | *bold* | | *italic* / _italic_ | _italic_ | | ~~strike~~ | ~strike~ | | `inline code` | `inline code` (kept) | | ```fenced block``` | ```fenced block``` (kept) | | # Heading | *Heading* | | [text](url) | text (url) | | ![alt](url) | alt (url) | | - item / * item | • item | | 1. item | 1. item (kept) | | > quote | > quote (kept) | | --- / *** | (removed — WA has no HR) |

Install

npm install n8n-nodes-md-to-whatsapp

Or in n8n UI: Settings → Community Nodes → Install → search n8n-nodes-md-to-whatsapp

Usage

Mode 1: Text

Provide Markdown directly in the parameter panel. The node outputs a single item with the converted WhatsApp text.

Mode 2: JSON Field (Streaming)

Read Markdown from a field on each input item, write the converted WhatsApp text to a new field. Preserves all other fields. Streams naturally — N input items become N output items.

Development

npm install
npm run build       # compile TypeScript
npm run lint        # eslint
npm run dev         # watch mode + n8n integration

Learn How to Build Your Own n8n Node

This repository is also a learning artifact. See LEARNING.md for a comprehensive guide (in Indonesian) covering:

• Declarative vs Programmatic node patterns
• Project structure conventions
• Properties system, display options, routing
• Expressions & templating
• Build, test, publish workflow
• Common pitfalls (with fixes!)

The guide is based on the source of scaffold-node.mjs from kelvinzer0/n8n-openapi-node-ultimate and this actual implementation.
