ijji

From: Instance to JSON, JSON to Instance (pronounced like e-hee)

is a library that provides a couple of functions to convert class instances to json, and json to class instances. Ah, it also offers a couple of types for typing like a champion.

run:

npm i enzodiazdev@ijji

Super simple example

import {json_to_instance, instance_to_json} from "@enzodiazdev/ijji";
class Person {
    public name:string
    constructor(name:string){
        this.name = name;
    }
    public hi():void {
        console.log("hi!");
    }
}
const lottie = new Person("lottie");
lottie.hi(); // "hi!"
database.write( instance_to_json(lottie) );
const john_data = database.get("john");
john_data.hi(); // ERROR, 'hi()' is not a function
const john = json_to_instance(john_data, Person);
john_data.hi(); // "hi!"
//ERROR: {name:number, age: string} does not match Person. 
const pepe = json_to_instance({name:10, age:"0"}, Person)

you can also:

import {PropertiesOf} from "@enzodiazdev/ijji";
const john_data:PropertiesOf<Person> = database.get("john");

In your own class

import {instance_to_json, PropertiesOf} from "@enzodiazdev/ijji";
class Person {    
    public name:string
    constructor(name:string){
        this.name = name;
    }
    public hi():void {
        console.log("hi!");
    }
    public to_json():PropertiesOf<this> {
        return instance_to_json(this);
    }
}

That’s all.
