Nucleoid
[](http://nucleoid.com/)
Nucleoid low-code framework lets you build your APIs with the help of AI and built-in datastore in declarative runtime engine.
As writing just like any other codes in Node.js, AI inside the runtime rerenders the very same JavaScript codes and makes the necessary adjustments in the state as well as stores on the disk so that your application doesn't require external database or anything else.
## How it works
I. Write your business logic in JavaScript
II. Nucleoid renders your codes with AI
III. Creates APIs with built-in datastore
## Hello World
```shell
> npm i nucleoidjs
```
Once installed, you can simply run with Express.js
```javascript
const app = nucleoid();
class User {
constructor(name) {
this.name = name;
}
}
// 👇 This is it!
app.post("/users", () => {
new User("Daphne");
});
app.listen(3000);
```
> :bulb: **This is pretty much it, thanks to AI in the runtime, only with this :point_up_2:, you successfully persisted your first object without external database.**
## Features
- Immediately start writing business logic
- Internal Data Management
- All you need is JavaScript
- Lighting fast
## Nucleoid IDE
Nucleoid IDE is a web interface that helps to run very same npm package with OpenAPI.

### Under the hood: Declarative Runtime Engine
Nucleoid is a declarative runtime engine that applies declarative programming at the runtime as rerendering JavaScript statements and creating the graph, so as a result, the declarative runtime system isolates a behavior definition of a program from its technical instructions and executes declarative statements, which represent logical intention without carrying any technical detail.
