Scan your markdown files for unsafe urls and remove them so you don't get spread bad stuff!

Markdown Safe Web Browsing

---

Background

I started with this tweet by @seanallen where he added a URL into a YouTube video description.

The URL became compromised within the week of adding it, and his channel was flagged with strike 1.

I realised there isn't anything out there to prevent this from happening to anyone's repository.

Usage

1. Install the module from npm

   # locally
   npm i @markbattistella/markdown-safe-link
   
   # globally
   npm i @markbattistella/markdown-safe-link -g

2. Run it from your terminal

   markdown-safe-link \
       --api="<YOUR_API_KEY_HERE>" \
       --dir="~/projects/my-docs/" \
       --replace="~~UNSAFE~~"

Github action

If you want to use this as part of your repository there is also an action you can use.

Requirements

You need to get your own API for Google Safe Browsing as there are limits to the number of calls made.

Configuration

Name	Description
dir	The directory to scan md files
api	Google API for scanning URLs
