@meshtastic/sdk-storage-sqlocal

SQLite WASM persistence adapters for @meshtastic/sdk. Implements the SDK's per-slice repository ports (MessageRepository, future NodesRepository, TelemetryRepository) against a single OPFS-backed SQLite database.

Drizzle ORM provides typed queries; sqlocal handles the WASM runtime and OPFS-backed storage. Multi-tab coordination uses the Web Locks API for write exclusion and BroadcastChannel for cross-tab change notifications.

Install

pnpm add @meshtastic/sdk @meshtastic/sdk-storage-sqlocal

Headers

OPFS in browsers requires cross-origin isolation. Serve your app with:

Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Embedder-Policy: require-corp

Quickstart

import { MeshClient, MeshRegistry } from "@meshtastic/sdk";
import { createSqlocalDb } from "@meshtastic/sdk-storage-sqlocal";
import { SqlocalMessageRepository } from "@meshtastic/sdk-storage-sqlocal/chat";

const db = await createSqlocalDb({ databasePath: "meshtastic.db" });

const registry = new MeshRegistry();
registry.create(connectionId, {
  transport,
  chat: {
    repository: new SqlocalMessageRepository(db, { deviceId: connectionId }),
    retention: { maxPerBucket: 1000, olderThanMs: 90 * 24 * 60 * 60 * 1000 },
  },
});

Schema

Single database per origin. Every table has a device_id column so a multi-device MeshRegistry can share one DB safely.

Table	Purpose
messages	Chat (text + waypoints)
nodes	Node DB snapshot per device
telemetry	Per-node ring buffer of telemetry readings
_schema	Migration version
