sqlite3

This runner provides integration with the sqlite3 driver, allowing ts-sql-query to execute queries on SQLite databases. It wraps an instance of a connected SQLite database and must be used in combination with a ts-sql-query connection.

Supported databases

• SQLite

Do not share connections between requests

A ts-sql-query connection object — along with the query runner instances passed to its constructor — represents a dedicated connection to the database.

Therefore, you must not share the same connection object between concurrent HTTP requests. Instead, create a new connection object for each request, along with its own query runners.

Even if the query runner internally uses a connection pool, the ts-sql-query connection still represents a single active connection, acquired from the pool. It must be treated as such and never reused across requests.

Using a single connection

Enables executing queries through a dedicated sqlite3 connection.

import { Database } from 'sqlite3';
import { Sqlite3QueryRunner } from "ts-sql-query/queryRunners/Sqlite3QueryRunner";

const db = new Database('./database.sqlite');

async function main() {
    const connection = new DBConnection(new Sqlite3QueryRunner(db));
    // Do your queries here
}
