sqlite

🚧 A Work in Progress. Do Not Use 🚧

An experimental SQLite library for Node using Neon

Goals

• APIs
  • Query binding
  • Connection creation and closing
  • Connection pooling
  • Parallel queries
  • Serialization
  • Traces and profiling
  • Interrupting queries
  • Exporting a database
• Modern infrastructure
• Target latest node and electron versions
• Promise based API
• Blob support
• ESNext BigInt support
• SQLite extensions support
• Typescript support
• Query caching support
• Extensive documentation and examples using docusarus, guides and examples
• Bundle sqlite if system does not have it installed
• Support for larger subset of SQLite API (compared to node-sqlite3)
• Better performance (compared to node-sqlite3)

Ideal API

import Sqlite from '@sqlite/sqlite';

const connector = new Sqlite();

// Creating a regular async connection
const conn = await connection.open({
  database: '/path/to/database', // ':memory:'
  verbose: true                  // process.env.NODE_ENV !== 'production'
});

// Parallel queries
await Promise.all([
  conn.run('SELECT * FROM users'),
  conn.run('UPDATE tbl SET name = ? WHERE email = ?', 'bar', 2)
]);

// Statement currying
const updateTables = await db.statement('UPDATE tbl SET name = ? WHERE email = ?');
const result = await updateTables('john', '[email protected]');
console.log(result);

// Batching queries
const updateTables = await db.batch(
  `
  ATTACH DATABASE ':memory:' AS my_attached;
  BEGIN;
  CREATE TABLE my_attached.foo(x INTEGER);
  INSERT INTO my_attached.foo VALUES(42);
  END
  `;
);
const updateTables = await db.batch([
  'ATTACH DATABASE ':memory:' AS my_attached;',
  'BEGIN;',
  'CREATE TABLE my_attached.foo(x INTEGER);',
  'INSERT INTO my_attached.foo VALUES(42);',
  'END'
]);

Local Development

git clone https://github.com/sqlite-js/sqlite
cd sqlite
yarn
yarn test

Prior art

Yarn wouldn't exist if it wasn't for excellent prior art. Sqlite has been inspired by the following projects:

• better-sqlite
• sqlite3
• sqlite
• rusqlite
