PouchDB is a free and open-source JavaScript DBMS inspired by Apache CouchDB (document-oriented NoSQL DBMS) that is designed to run inside a web browser. It was designed with the intention of serving web developers and to run smoothly within a browser. Applications utilize a system where, while offline, data is stored locally, then, when back online, the data is synchronized with Apache CouchDB and between clients. Thus, data is synchronized regardless of login context.[01]

Checkpoints
PouchDB allows users to enable or disable replication checkpoints (which would be modified based on system performance goals and/or usage), which are used for synchronization across the local and remote servers. These checkpoints are non-blocking.
Compression[04]
PouchDB doesn't currently support compression by default, however there is a plugin (Transform Pouch) that allows for compression of data.
Data Model[05][06]
PouchDB uses an unstructured document data model, where documents are JSON serializable. It also supports attachments, which store binary data.
Indexes[07]
Starting with version 2.2.0, PouchDB supports secondary indexes using B-trees. The default index is build on the _id field.
Query Interface[08]
PouchDB utilizes a custom API for its query interface. As it is designed for web browsers, this API supports callbacks, promises, and async functions.
