x/sqlite_hello Deno Module

The sqlite-hello SQLite extension is available to Deno developers with the x/sqlite_hello 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_hello from "https://deno.land/x/sqlite_hello@v0.1.0-alpha.41/mod.ts";

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

db.enableLoadExtension = true;
sqlite_hello.load(db);

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

console.log(version);

Like x/sqlite3, x/sqlite_hello 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_hello does not work with x/sqlite, which is a WASM-based Deno SQLite module that does not support loading extensions.
