What I Built
I created Dev.to Email Publisher, a handy tool that lets developers post articles to the Dev.to platform straight from their email inbox! Powered by Postmark’s inbound email feature and integrated with the Dev.to API, this project showcases a practical way to streamline content creation. It’s a simple yet reusable solution that can be adapted for other platforms or used as-is for Dev.to. My goal was to make publishing as easy as sending an email, saving time for busy developers who want to share their ideas quickly.
Demo
- Clone the repostitory: Repostiory
- Connect Dev.to: Add your Dev.to API key (found in Dev.to settings under “Extensions”).
- Send Test Email: From your inbox, send to your email registered in postmark inbound:
