Next-generation React databases
summary
WatermelonDB is a relational, observable database for React and React Native that lazy-loads data, moves queries into native threads and uses SQLite on mobile and LokiJS in a web worker, so apps launch in about 200 ms launch even with 10,000 records. Queries and records are RxJS-observable and a React HOC injects live results. It ships indexing, caching, batching, sync-tracking primitives and Flow types, claiming relational joins in roughly a millisecond and adapters for cross-platform use.
