@signalapp/sqlcipher

A fast N-API-based Node.js addon wrapping sqlcipher and Signal-specific FTS5 segmenting APIs.

Usage

import Database from '@signalapp/sqlcipher';

const db = new Database('/path/to/db');

db.exec(`
  CREATE TABLE t (
    a INTEGER,
    b TEXT,
    c BLOB
  );
`);

const insert = db.prepare('INSERT INTO t (a, b, c) VALUES ($a, $b, $c)');
insert.run({ a: 1, b: 'hello', c: Buffer.from('world') });
insert.run({ a: 2, b: 'world', c: Buffer.from('hello') });

console.log(db.prepare('SELECT * FROM t').all());
