fdnext is a high-performance, one-stop parsing engine for memory chips. It provides comprehensive support for part-number (PN) decoding, NAND Flash ID inspection, and database searches across multiple vendors and storage technologies.
FlashMaster is the flagship implementation of the fdnext engine—a workstation-grade intelligence platform for engineers.
fdnext is designed as the backbone for memory chip intelligence. It normalizes complex vendor data into structured, actionable information, enriched with local resources and verified against strict result contracts.
- Part Number Decoding: Instant decoding of raw NAND, eMMC, UFS, DRAM, and more.
- Flash ID Decoding: Deep inspection of NAND Flash IDs through a typed identifier API.
- Smart Resource Flow: Bundled
fdb,mdb, and language packs with Micron FBGA code lookup. - Universal Dispatch: Shared runtime layer for native Node.js HTTP and Cloudflare Workers.
- Data Maintenance: CLI tools for FDB/MDB generation, crawling, DecodePack management, and evidence metadata auditing.
fdnext is organized as a strict TypeScript monorepo. The main package is now batteries-included, while platform packages stay thin adapters.
- Core (
@itxtech/fdnext-core): Engine, DecodePack rules/compiler, embedded resources, result contract, and shared runtime. - Adapters: Native support for Node.js HTTP and Cloudflare Workers.
- Data Tools (
@itxtech/fdbgen): Database generation, MDB crawling, and resource aggregation tools. - Testing (
@itxtech/fdnext-contract-test): Result schema and behavior contract validation. - Legacy compatibility:
@itxtech/fd-serverexposes the old FlashDetector / FDWebServer HTTP API for FlashMaster Classic migration deployments, with Cloudflare Workers as the preferred deployment path.
This project uses pnpm for workspace management.
