import { createClient } from "@libsql/client";

export const turso = createClient({
    url: "file:local.db",
    syncUrl: process.env.TURSO_DATABASE_URL,
    authToken: process.env.TURSO_AUTH_TOKEN,
    syncInterval: 60000,
});

await turso.batch(
    [
        "CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT)",
        {
            sql: "INSERT INTO users(name) VALUES (?)",
            args: ["Iku"],
        },
    ],
    "write",
);

await turso.execute({
    sql: "SELECT * FROM users WHERE id = ?",
    args: [1],
});
