GraphDB Migration Tool

A CLI and library for migrating data from JSON and SQL sources to graph databases (Gremlin-compatible, e.g., Azure Cosmos DB). Current version 0.0.2, stable but low release cadence. Supports JSON-to-Gremlin, JSON-to-graph, and SQL-to-graph conversion using Handlebars templates. Key differentiator: leverages a Vertex-Edge format inspired by Azure Cosmos Graph DB, enabling flexible mapping of flat data to graph structures. Ships TypeScript types. Limited to basic database dialects (mssql, mysql, sqlite, postgres). Minimal ecosystem and documentation, no active maintenance.
