NeDB

What it is

NeDB is an embedded persistent database written entirely in JavaScript. It provides a simple and efficient way to store data locally, making it ideal for applications that require local storage without the overhead of setting up a full-fledged database server.

NeDB stands out as a lightweight, easy-to-use solution for local storage needs in JavaScript applications, offering simplicity without the need to set up external databases.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited scalability for large datasets

   NeDB is designed for small-scale, local storage and may suffer from performance degradation with very large datasets.

2. 02

   Poor concurrency handling

   Due to its single-threaded nature, NeDB can struggle with concurrent read/write operations in high-load scenarios.

3. 03

   Lack of advanced query capabilities

   NeDB supports basic querying but lacks complex join and aggregation features available in more robust databases like MongoDB or PostgreSQL.

4. 04

   No built-in replication or clustering support

   For distributed applications, NeDB does not offer mechanisms for data replication or sharding to ensure high availability and fault tolerance.

What it does well

• Embedded database for local storage

• Persistent data storage without a server

• Simple API for easy integration
