What it is
PouchDB is a free, open-source JavaScript database for browser and Node.js applications. It keeps documents locally so applications can continue working offline, then synchronizes data bidirectionally with CouchDB-compatible servers when online. The same API is used in browsers and Node.js. Browser storage uses IndexedDB by default, while the documented Node.js adapter uses Node’s native SQLite module with Node.js versions later than 22.5.0. Supported server integrations include CouchDB 1.x, 2.x, and 3.x, Cloudant, and PouchDB Server. PouchDB is framework-agnostic and can work with Angular, React, Ember, Backbone, or another framework. It also runs with Cordova/PhoneGap, NW.js, Electron, and Chrome apps. Documents must be serializable as JSON, and attachments can be base64-encoded strings or Blob objects. Direct synchronization with a non-CouchDB database requires a backend that speaks the CouchDB replication protocol. Platforms listed are Android, API, extension, iOS, self-hosted, web, and Windows. The project lists GitHub Discussions, Slack, and Stack Overflow for discussion.
