sqlite-wasm OO1

This runner provides integration with the WebAssembly-based @sqlite.org/sqlite-wasm Object Oriented API 1, 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

Tip

better-sqlite3 supports synchronous query execution. See the Synchronous query runners for more information.

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 WebAssembly-based @sqlite.org/sqlite-wasm Object Oriented API 1 connection.

import sqlite3InitModule from '@sqlite.org/sqlite-wasm';
import { Sqlite3WasmOO1QueryRunner } from "ts-sql-query/queryRunners/Sqlite3WasmOO1QueryRunner";

async function main() {
    const sqlite3 = await sqlite3InitModule();
    const db: Database = new sqlite3.oo1.DB();
    const connection = new DBConnection(new Sqlite3WasmOO1QueryRunner(db));
    // Do your queries here
}
