KeyStore JS

keystore.js

//	alternative for globally reusable variables

//	supports contexts
//	can store all javascript types

//	to create object-based unique contexts,
//		we advise assigning a uuidv4 to that object
//		then using that uuid as the context for that object.

//	best use cases:
//		- when you're using chained promises
//			instead of cluttering your args & chains w/ variables
//			use keystore contexts instead;
//			makes your code cleaner & your promises more reusable.

class KeyStore{
	constructor(){
		console.log("Yay KeyStore!");
		this.storage = {};
		this.contexts = {};
	}
	set(_key, _value){
		this.storage[_key] = _value;
	}
	get(_key){
		return this.storage[_key];
	}
	pullContext(_context){
		if(this.contexts[_context]){
			return this.contexts[_context];
		}else{
			this.contexts[_context] = {
				storage: {},
				set: function(_key, _value){
					this.storage[_key] = _value;
					return this;
				},
				get: function(_key){
					return this.storage[_key];
				}
			};
			return this.contexts[_context];
		}
	}
	clearContext(_context){
		this.contexts[_context] = null;
		return true;
	}
}

// usage

let _KeyStore = new KeyStore();
    
_KeyStore.set("yeah", "lol");
    
console.log(_KeyStore.get("yeah"));
// lol
    
console.log(_KeyStore.pullContext("a").set("b", 2).get("b"));
// 2
