better-sqlite3 with electron v17 support
npm install @princeofmath/yan-better-sqlite3
The fastest and simplest library for SQLite3 in Node.js. This particular fork supports multiple-cipher encryption using SQLite3MultipleCiphers. Check usage to learn more.
- Full transaction support
- High performance, efficiency, and safety
- Easy-to-use synchronous API (better concurrency than an asynchronous API... yes, you read that correctly)
- Support for user-defined functions, aggregates, virtual tables, and extensions
- 64-bit integers (invisible until you need them)
- Worker thread support (for large/slow queries)
- Encryption support using multiple algorithms

better-sqlite3 is used by thousands of developers and engineers on a daily basis. Long nights and weekends were spent keeping this project strong and dependable, with no ask for compensation or funding, until now. If your company uses better-sqlite3, ask your manager to consider supporting the project:
- Become a GitHub sponsor
- Become a backer on Patreon
- Make a one-time donation on PayPal
Also head over to SQLite3MultipleCiphers repo and give some support to the developer to keep this very useful extension alive.

`js
const db = require('better-sqlite3-multiple-ciphers')('foobar.db', options);
const row = db.prepare('SELECT * FROM users WHERE id = ?').get(userId);
console.log(row.firstName, row.lastName, row.email);
`
##### In ES6 module notation:
`js`
import Database from 'better-sqlite3-multiple-ciphers';
const db = new Database('foobar.db', options);
A database can be encrypted and decrypted simply using key and rekey PRAGMA statements.
Running this will encrypt the database using the default cipher:
`js
const db = require('better-sqlite3-multiple-ciphers')('foobar.db', options);
db.pragma("rekey='secret-key'");
db.close();
`
To read an encrypted database (assuming default cipher):
`js
const db = require('better-sqlite3-multiple-ciphers')('foobar.db', options);
db.pragma("key='secret-key'");
const row = db.prepare("SELECT * FROM users WHERE id = ?").get(userId);
console.log(row.firstName, row.lastName, row.email);
`

- node-sqlite3 uses asynchronous APIs for tasks that are either CPU-bound or serialized. That's not only bad design, but it wastes tons of resources. It also causes mutex thrashing which has devastating effects on performance.node-sqlite3
- exposes low-level (C language) memory management functions. better-sqlite3 does it the JavaScript way, allowing the garbage collector to worry about memory management.better-sqlite3
- is simpler to use, and it provides nice utilities for some operations that are very difficult or impossible in node-sqlite3.better-sqlite3
- is much faster than node-sqlite3 in most cases, and just as fast in all other cases.
#### When is this library not appropriate?
In most cases, if you're attempting something that cannot be reasonably accomplished with better-sqlite3, it probably cannot be reasonably accomplished with SQLite3 in general. For example, if you're executing queries that take one second to complete, and you expect to have many concurrent users executing those queries, no amount of asynchronicity will save you from SQLite3's serialized nature. Fortunately, SQLite3 is very very fast. With proper indexing, we've been able to achieve upward of 2000 queries per second with 5-way-joins in a 60 GB database, where each query was handling 5–50 kilobytes of real data.
If you have a performance problem, the most likely causes are inefficient queries, improper indexing, or a lack of WAL mode—not better-sqlite3 itself. However, there are some cases where better-sqlite3` could be inappropriate:
- If you expect a high volume of concurrent reads each returning many megabytes of data (i.e., videos)
- If you expect a high volume of concurrent writes (i.e., a social media site)
- If your database's size is near the terabyte range
For these situations, you should probably use a full-fledged RDBMS such as PostgreSQL.
