The PubScale plugin integrates your Obsidian vault with PlanetScale, allowing you to seamlessly sync, update, and manage markdown notes in a database. This plugin enables users to use PlanetScale as content storage while keeping Obsidian as the primary content editor. With features like publishing notes to a database and deleting them directly from Obsidian, PubScale gives users complete control over which notes are synced. It uses note titles as identifiers for operations, ensuring clarity and organization. The setup is simple, requiring basic configuration of a PlanetScale database and integration of credentials within Obsidian.
