@tanstack/electron-db-sqlite-persistence

Thin Electron bridge for TanStack DB SQLite persistence.

Public API

• exposeElectronSQLitePersistence(...) (main process)
• createElectronSQLitePersistence(...) (renderer process)
• persistedCollectionOptions(...) (re-exported from core)

Use @tanstack/electron-db-sqlite-persistence/main and @tanstack/electron-db-sqlite-persistence/renderer if you prefer explicit process-specific entrypoints.

Main process

import { ipcMain } from 'electron'
import { createNodeSQLitePersistence } from '@tanstack/node-db-sqlite-persistence'
import { exposeElectronSQLitePersistence } from '@tanstack/electron-db-sqlite-persistence/main'
import Database from 'better-sqlite3'

const database = new Database(`./tanstack-db.sqlite`)

const persistence = createNodeSQLitePersistence({
  database,
})

const dispose = exposeElectronSQLitePersistence({
  ipcMain,
  persistence,
})

// Call dispose() and database.close() during shutdown.

Renderer process

import { createCollection } from '@tanstack/db'
import { ipcRenderer } from 'electron'
import {
  createElectronSQLitePersistence,
  persistedCollectionOptions,
} from '@tanstack/electron-db-sqlite-persistence'

type Todo = {
  id: string
  title: string
  completed: boolean
}

const persistence = createElectronSQLitePersistence<Todo, string>({
  ipcRenderer,
})

export const todosCollection = createCollection(
  persistedCollectionOptions<Todo, string>({
    id: `todos`,
    getKey: (todo) => todo.id,
    persistence,
    schemaVersion: 1, // Per-collection schema version
  }),
)

Notes

• The renderer API mirrors other runtimes: one shared create...Persistence.
• Collection mode (sync-present vs sync-absent) and schemaVersion are resolved per collection and forwarded across IPC automatically.
