RxDB: Open-Source Reactive Database for JavaScript Applications
IndexedDB/WebSQL-based NoSQL database with reactive interface, queries, schemas, sync and more for front-end browser environments.
What is RxDB?
RxDB is an open-source, reactive database for JavaScript applications. It is based on indexedDB/WebSQL under the hood but brings a NoSQL interface with queries, schemas, sync and much more to the front-end browser environment.
Some key features and benefits of RxDB include:
- Reactive/Realtime - Data changes are propagated through reactivity
- Schema-based - Define a JSON schema for data integrity
- Offline-first - Works offline by default and syncs when online
- Queryable - Find data with a MongoDB-like query syntax
- Multiplatform - Runs in any JavaScript environment like web, mobile, server, desktop etc.
- Replication - Built-in sync functionality via PouchDB
RxDB follows reactive programming paradigms to update queries, indexes and subscriptions automatically when data changes. The API is easy to use with a small learning curve for those familiar with NoSQL databases.
Some ideal use cases for RxDB include: realtime web and mobile apps, offline-capable apps, cross-platform JavaScript apps that share data, and for replacing client-server architectures with peer-to-peer sync.
