better-sqlite3

The fastest and simplest library for SQLite3 in Node.js.

• Full transaction support
• Geared for performance, efficiency, and safety
• Easy-to-use synchronous API (faster than an asynchronous API... yes, you read that correctly)
• Custom SQL function support
• 64-bit integer support (invisible until you need it)

How other libraries compare

	select 1 row  get()	select 100 rows   all()	select 100 rows iterate() 1-by-1	insert 1 row run()	insert 100 rows in a transaction
better-sqlite3	1x	1x	1x	1x	1x
sqlite and sqlite3	8.4x slower	3.7x slower	28.2x slower	3.6x slower	6.0x slower

You can verify these results by running the benchmark yourself. Both npm/sqlite and npm/sqlite3 have nearly identical performance because they both use the same engine.

Installation

npm install --save better-sqlite3

If you have trouble installing, check the troubleshooting guide.

Usage

var Database = require('better-sqlite3');
var db = new Database('foobar.db', options);
 
var row = db.prepare('SELECT * FROM users WHERE id=?').get(userId);
console.log(row.firstName, row.lastName, row.email);

Why should I use this instead of node-sqlite3?

• 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.
