Entity class

Base class for all your entities

import Entity from 'entity-class';

const entity = new Entity({
  name: 'John',
  last_name: 'Carpenter'
});

console.log(entity.get('name')); // returns name

Made to be extended

import Entity from 'entity-class';

interface IUser {
 name: string;
 age: number;
 last_name: string;
}

class User extends Entity<IUser> {
 getName() {
   return this.get('name');
 }

 getLastName() {
   return this.get('last_name');
 }

 getAge() {
   return this.get('age');
 }

 getFullName() {
   return `${this.getName()} ${this.getLastName()}`;
 }

 isAdult() {
   return this.getAge() > 21;
 }
}

const user = new User({
  name: 'John',
  age: 12,
  last_name: 'Carpenter'
});

console.log(user.getFullName()): // returns full name of user

Full support for typescript

 import Entity from 'entity-class';

 interface IUser {
   name: string;
   last_name: string;
   age?: number;
 }

 class User extends Entity<IUser> {
   getName() {
     return this.get('name');
   }

   getLastName() {  // : string
     return this.get('last_name');
   }

   getAge() {  // : number | undefined
     return this.get('age');
   }

   getFullName() {
     return `${this.getName()} ${this.getLastName()}`;
   }
 }

 const user = new User({
   name: 'John',
 });

 // Will indicate error:
 // Argument of type '{ name: string; }' is not assignable to parameter of type 'IUser'.
 // Property 'last_name' is missing in type '{ name: string; }' but required in type 'IUser'
