x/sqlite_fastrand Deno Module

Tags Doc

The sqlite-fastrand SQLite extension is available to Deno developers with the x/sqlite_fastrand Deno module. It works with x/sqlite3, the fastest and native Deno SQLite3 module.

import { Database } from "https://deno.land/x/sqlite3@0.8.0/mod.ts";
import * as sqlite_fastrand from "https://deno.land/x/sqlite_fastrand@v0.2.1-alpha.7/mod.ts";

const db = new Database(":memory:");

  db.enableLoadExtension = true;
  db.loadExtension(sqlite_fastrand.getLoadablePath());

  const [version] = db
    .prepare("select fastrand_version()")
    .value<[string]>()!;

  console.log(version);

Like x/sqlite3, x/sqlite_fastrand requires network and filesystem permissions to download and cache the pre-compiled SQLite extension for your machine. Though x/sqlite3 already requires --allow-ffi and --unstable, so you might as well use --allow-all/-A.

deno run -A --unstable <file>

x/sqlite_fastrand does not work with x/sqlite, which is a WASM-based Deno SQLite module that does not support loading extensions.
