sqlite

flextree-sqlite-adapter is the sqlite database adapter for flextree, used to translate flextree operations into sqlite database operations.

Install

better-sqlite3 is a peerDependency and must be installed by the consumer:

npm install flextree-sqlite-adapter better-sqlite3
// or
yarn add flextree-sqlite-adapter better-sqlite3
// or
pnpm add flextree-sqlite-adapter better-sqlite3
// or
bun add flextree-sqlite-adapter better-sqlite3

The adapter no longer bundles better-sqlite3, so installing flextree-sqlite-adapter does not trigger native module compilation; better-sqlite3 is installed on demand by the consumer.

Usage

The adapter no longer creates the database connection itself. Pass an already-created better-sqlite3 Database instance to the constructor; the connection lifecycle (open/close) is managed by the caller.

import Database from 'better-sqlite3'
import SqliteAdapter from 'flextree-sqlite-adapter'

// The caller creates and owns the database instance
const db = new Database('tree.db')
const sqliteDriver = new SqliteAdapter(db)

const tree = new FlexTreeManager('tree', {
    adapter: sqliteDriver,
})
