Table of contents

import sqlite from "sqlite3";
import { table, AnyPrintable, RowsArray } from "../../src";

With a DB connector

const it = sqlite.verbose();
const db = new it.Database(":memory:");

const runS = (q: string) =>
    new Promise<any[]>((rs, rj) =>
        db.all(q, (e: any, r: any) => (e ? rj(e) : rs(r)))
    );

We can implement a version that is aware of the types

const run = <T extends AnyPrintable>(it: T): Promise<RowsArray<T>> =>
    runS(it.stringify());

Then, with some tables

const t1 = table(["a", "b", "c"], "t1");
await runS(`CREATE TABLE t1(a,b,c);`);
await runS(`INSERT INTO t1 VALUES(1,2,3);`);

We can run queries

const value = await run(t1.selectStar());
value;

[{ "a": 1, "b": 2, "c": 3 }]

Typescript knows the identifiers

value.map((it) => it.a);

//@ts-expect-error
value.map((it) => it.u);
