PouchDB features and specs

Offline-first Architecture
PouchDB is designed for offline-first applications, allowing users to access and interact with data without requiring a constant internet connection. It automatically syncs with a CouchDB-compatible server when a connection is available.
Cross-Platform Compatibility
PouchDB runs in the browser, Node.js, and other platforms, enabling developers to build applications that work consistently across desktop and mobile devices.
CouchDB Compatibility
Being compatible with CouchDB, PouchDB allows developers to easily sync data between the client and server, leveraging CouchDB's replication and conflict resolution features.
Easy to Use
PouchDB provides a simple API that is easy to understand and use, which can speed up the development process, especially for developers familiar with document-based databases.
Rich Querying Capabilities
PouchDB supports MapReduce, Mango queries, and a few advanced indexing features that offer flexible ways to query data based on specific requirements.

Possible disadvantages of PouchDB

Limited Built-in Security
While PouchDB can work offline, securing data at rest or implementing authentication requires additional work, as it does not provide substantial security features out of the box.
Database Size Limitations
When used in the browser, PouchDB's storage capacity is limited by the browser's storage limits, which might not be sufficient for certain applications with large datasets.
Performance Overhead
PouchDB can introduce some performance overhead due to its JavaScript implementation and the use of MapReduce on larger datasets, which may not be as fast as native database implementations.
Complex Conflict Resolution
While conflict resolution is supported, handling conflicts can become complex, requiring developers to implement robust conflict management strategies within their applications.
Dependency on CouchDB
Although PouchDB is designed to work offline, the synchronization capabilities depend on CouchDB (or a compatible server), meaning that certain features may not work without such a backend setup.

A Future for SQL on the Web
Sql.js is pretty hard to use as is otherwise you run out of memory really quickly. I was trying to use it as the in-memory SQL flavor for an open source data ide [0] but my naive approach of `SELECT * FROM VALUES (...), ...` would run out of memory after only a few hundred rows. I ended up switching to https://github.com/agershun/alasql which could handle up to 80MB of data or so. I don't think this is a... - Source: Hacker News / almost 4 years ago
