Nucleoid

AI-managed Low-code Framework for Node.js

Nucleoid uses symbolic (logic-based) AI in the runtime that tracks given statements in JavaScript and creates relationships between variables, objects, and functions etc. in the graph. So, as writing just like any other codes in Node.js, the runtime translates your business logic to fully working application by managing the JS state as well as storing in the built-in data store, so that your application doesn't require external database or anything else.

How it works

I. Write your business logic in JavaScript (TypeScript support coming soon)

II. Nucleoid runtime renders your codes

III. Creates APIs with the built-in datastore

Hello World ⚡

> npm i nucleoidjs

Once installed, you can simply run with Express.js

const nucleoid = require("nucleoidjs");
const app = nucleoid();

class Item {
  constructor(name, barcode) {
    this.name = name;
    this.barcode = barcode;
  }
}
nucleoid.register(Item);

// 👍 Only needed a business logic and 💖
// "Create an item with given name and barcode,
// but the barcode must be unique"
app.post("/items", (req) => {
  const name = req.body.name;
  const barcode = req.body.barcode;

  const check = Item.find((i) => i.barcode === barcode);

  if (check) {
    throw "DUPLICATE_BARCODE";
  }

  return new Item(name, barcode);
});

app.listen(3000);

💡 This is pretty much it, thanks to Nucleoid runtime, only with this 👆, you run your business logic and successfully persisted your object without external database.

Under the hood: Declarative Runtime Environment

Nucleoid is an implementation of symbolic AI for declarative (logic) programming at the runtime. As mentioned, the declarative runtime environment manages JavaScript state and stores each transaction in the built-in data store by declaratively rerendering JavaScript statements and building the knowledge graph (base) as well as an execution plan.

The declarative runtime isolates a behavior definition of a program from its technical instructions and executes declarative statements, which represent logical intention without carrying any technical detail. In this paradigm, there is no segregation regarding what data is or not, instead approaches how data (declarative statement) is related with others so that any type of data including business rules can be added without requiring any additional actions such as compiling, configuring, restarting as a result of plasticity. This approach also opens possibilities of storing data in the same box with the programming runtime.

In short, the main objective of the project is to manage both of data and logic under the same runtime. The declarative programming paradigm used by Nucleoid allows developers to focus on the business logic of the application, while the runtime manages the technical details.This allows for faster development and reduces the amount of code that needs to be written. Additionally, the sharding feature can help to distribute the load across multiple instances, which can further improve the performance of the system.

OpenAPI Integration with Nucleoid IDE

Nucleoid IDE is a web interface that helps to run very same npm package with OpenAPI.

Benchmark

This is the comparation our sample order app in Nucleoid IDE against MySQL and Postgres with using Express.js and Sequelize libraries.

https://nucleoid.com/ide/sample

Performance benchmark happened in t2.micro of AWS EC2 instance and both databases had dedicated servers with no indexes and default configurations.

https://github.com/NucleoidJS/benchmark

This does not necessary mean Nucleoid runtime is faster than MySQL or Postgres, instead databases require constant maintenance by DBA teams with indexing, caching, purging etc. however, Nucleoid tries to solve this problem with managing logic and data internally. As seen in the chart, for applications with average complexity, Nucleoid's performance is close to linear because of on-chain data store, in-memory computing model as well as limiting the IO process.
