better-sqlite3
Advanced tools
Simple and expressive SQLite3 bindings for Node.js, with full transaction support.
better-sqlite3 is a fast and simple SQLite3 library for Node.js applications. It provides a synchronous API for interacting with SQLite databases, making it easier to write and maintain code. The library is designed to be efficient and easy to use, with a focus on performance and simplicity.
Database Connection
This feature allows you to establish a connection to an SQLite database. The `Database` constructor takes the path to the database file as an argument.
const Database = require('better-sqlite3');
const db = new Database('my-database.db');
Executing SQL Statements
This feature allows you to prepare and execute SQL statements. The `prepare` method creates a prepared statement, and the `all` method executes the statement and returns all matching rows.
const stmt = db.prepare('SELECT * FROM users WHERE age > ?');
const users = stmt.all(18);
Inserting Data
This feature allows you to insert data into the database. The `run` method executes the prepared statement with the provided parameters.
const insert = db.prepare('INSERT INTO users (name, age) VALUES (?, ?)');
const info = insert.run('John Doe', 30);
Transaction Management
This feature allows you to manage transactions. The `transaction` method creates a transaction that can execute multiple statements atomically.
const insert = db.prepare('INSERT INTO users (name, age) VALUES (?, ?)');
const insertMany = db.transaction((users) => {
for (const user of users) insert.run(user.name, user.age);
});
insertMany([{ name: 'Alice', age: 25 }, { name: 'Bob', age: 35 }]);
Custom Functions
This feature allows you to define custom SQL functions. The `function` method registers a new function that can be used in SQL statements.
db.function('add', (a, b) => a + b);
const result = db.prepare('SELECT add(2, 3)').get();
The `sqlite3` package is another popular SQLite library for Node.js. Unlike better-sqlite3, it provides an asynchronous API, which can be beneficial for non-blocking operations. However, it can be more complex to use due to the asynchronous nature of its API.
The `node-sqlite3` package is similar to `sqlite3` and provides an asynchronous API for SQLite. It is widely used and well-documented, but like `sqlite3`, it can be more challenging to work with compared to the synchronous API of better-sqlite3.
The `sql.js` package is a JavaScript library that runs SQLite in the browser using Emscripten. It is useful for web applications that need to use SQLite in a client-side environment. However, it is not designed for Node.js server-side applications like better-sqlite3.
