Hi Product Hunt! I'm excited to share NebulaDB with you today. I built NebulaDB to solve the challenges I faced when working with databases in TypeScript projects. Most existing solutions either lacked type safety or required complex ORM setups. NebulaDB gives you the best of both worlds - the flexibility of NoSQL with the safety of TypeScript. The reactive query system means your UI automatically updates when data changes, and the plugin architecture lets you extend functionality as needed. I'd love to hear your feedback and answer any questions you might have about NebulaDB. What database challenges are you facing in your projects?
