Polyglot Protocols: gRPC, GraphQL & FLASH Wire

FLASH DB provides dedicated protocol engines for low-latency polyglot microservices (gRPC), flexible web query APIs (GraphQL), and the native FLASH Wire binary protocol.

For the native TCP wire protocol (BSON, port 6744), see FLASH Wire Protocol.

1. High-Throughput Binary Protocol / gRPC (FlashGRPCServer)

Runs a dedicated binary TCP socket listener with protobuf-like length-prefixed framing for Go, Python, and Rust client integration:

import { FlashDatabase, FlashGRPCServer } from 'flash-zk';

const db = new FlashDatabase('rpc_db', { storagePath: './data' });
const grpcServer = new FlashGRPCServer(db, { port: 6743 });

await grpcServer.start();
console.log('⚡ gRPC binary service running on port 6743');

2. Zero-Knowledge GraphQL Engine (FlashGraphQL)

Execute standard GraphQL queries against collections with field projection and pagination:

import { FlashDatabase, FlashGraphQL } from 'flash-zk';

const db = new FlashDatabase('app_db', { storagePath: './data' });
const gql = new FlashGraphQL(db);

const response = await gql.execute(`
  {
    users(limit: 5) {
      name
      email
      balance
    }
  }
`);

console.log(response.data.users);
