When does this happen?
IF When using better-sqlite3 in an ESM context without proper CommonJS interop, the error 'Database is not a constructor' occurs.
How others solved it
THEN Implement a loader function that first attempts to load better-sqlite3 using `createRequire` (from 'module') to handle CommonJS modules, with a fallback to dynamic import and manual default export resolution. Always call this loader before using the Database constructor to ensure it is initialized.
async function loadSqlite() {
const { createRequire } = await import('module');
const require = createRequire(import.meta.url);
Database = require('better-sqlite3');
// test and return success
