I Built a Lightweight Embedded Database for Node.js — LioranDB

#typescript #javascript #database #node

I'm a 17-year-old full stack developer and CTO at Lioran Group.

A few months ago, I started building a fun prototype for a lightweight and embedded database for my own projects. While working on it, I realized it was saving me a lot of development time because the syntax is similar to MongoDB, while staying fully NoSQL and file-based.

Over the last 5 months, I focused on improving stability, performance, and reliability.

One of the major advantages of LioranDB is that it can run anywhere and is designed to be lightweight and memory-efficient.

For 1 million documents:

200 MB RAM
300 MB storage (including WAL + indexes)

To install:

npm i @liorandb/core

Sample Code:

import { LioranManager } from "@liorandb/core";

const manager = new LioranManager({
  // optional: where databases live on disk
  // rootPath: "./data",
});

const db = await manager.db("app");
const users = db.collection("users");

await users.insertOne({ email: "a@b.com", plan: "free" });

const found = await users.findOne({ email: "a@b.com" });
console.log(found);

await manager.close();
