Back in Hacktoberfest 2022, I kicked off a set of contributions aimed at making SQL DDL generation and schema visualization easier using open-source tools. This year, I revisited those efforts with a sharper focus on Draw.io plugin development.
🔧 What’s New in 2025
Draw.io remains a powerful tool for diagramming, but its native support for SQL workflows is limited. To bridge that gap, I’ve continued building and refining third-party plugins that allow:
- Importing SQL DDLs into Draw.io diagrams
- Exporting diagrams back into SQL DDL
- Improved foreign key line generation across multiple database types
- Support for PostgreSQL relationship arrows (finally!)
These updates are part of the sqltooling-drawio repo, which now includes better test coverage, multi-DB compatibility, and easier integration with the Draw.io desktop app.
🧪 Pull Requests & Plugin Highlights
I submitted two key PRs to the Draw.io repo:
While Draw.io contributions remain closed-source, these plugins can be manually installed and used with the desktop version or VSCode integration.
