## What it is
Dynalite is a JavaScript implementation of Amazon's DynamoDB API built on LevelDB, runnable as a CLI or embedded Node.js HTTP server with fast in-memory or persistent storage. It closely mimics live DynamoDB behavior, including limits and error messages, making it ideal for local development and testing.

## Use cases
- run a local DynamoDB server for testing
- mock DynamoDB in integration tests without the JVM
- start an in-memory DynamoDB in milliseconds
- test AWS SDK code against a fake DynamoDB endpoint
- persist test data locally with LevelDB
- replace DynamoDB Local in Node.js test suites

## When to choose
- you need a fast, lightweight DynamoDB mock that starts in milliseconds
- you want to avoid the JVM/Docker overhead of DynamoDB Local
- you're testing Node.js applications that use the AWS SDK
- you need programmatic embedding of a DynamoDB server in tests

## When to avoid
- you need full feature parity including transactions and the latest DynamoDB features
- you prefer the officially supported Amazon DynamoDB Local
- you need a production database rather than a test double

## Facets
- artifact type: library
- maturity: maintenance
- function: database, http-server, mocking, testing, cli
- domain: databases, developer-tools, testing, cloud-computing
- platform: cli, cross-platform
- tags: dynamodb, dynamodb-local, leveldb, aws-mock, test-double, in-memory-database, serverless-testing, nodejs
