typed-property

Strongly typed property definer, uses ArrayBuffer as memory backend. Supports all strong number types from uin8 to float64.

Supported property types

• uint8
• int8
• uint16
• int16
• uint32
• int32
• float32
• float64

And all types in little endian by using the LE postfix, like uint8LE.

Using as properties

You can use the library as you would use Object.defineProperty. You have to define strongly typed properties on an object.

const { TypedProperty } = require('typed-property');
 
function TypedClass(){
    // like Object.defineProperty(this, 'uint8', { get: ..., set: ... });
    TypedProperty.uint8(this, 'uint8');
}
 
const instance = new TypedClass();
instance.uint8 = -1;
console.log(instance.uint8); // 255

Using as TypeScript decorators

If you use TypeScript, you can utilize the decorators from the library. Don't forget to decorate your class as @typed.

import { typed, uint8 } from 'typed-property';
 
@typed
class TypedClass{
    @uint8
    uint8: number
}
 
const instance = new TypedClass();
instance.uint8 = -1;
console.log(instance.uint8); // 255
