@randajan/jet-base

Goal was to create universal structure for storing variables with watcher and validator.

Install

npm install @randajan/jet-base

or

yarn add @randajan/jet-base

Usage

Init

import Base from "@randajan/jet-base";

const base = new Base(true); //first argument = debug mode on/off

Set

function that simply assign values. For rewrite whole structure it can be used with object as first argument:

base.set({a:1, b:2, c:3, d:{x:123}});

or first argument could be path, and second argument value:

base.set("a", 1);
base.set("b", 2);
base.set("c", 3);
base.set("d.x", 123);

result will be the same.

Get

accessing stored values first argument could be path

base.get("d") == {x:123};
base.get("d.x") === 123;

result is everytime a deep copy.

Is / IsType / IsFull

simple comparing

base.is("d.x", 123) === true;
base.isType("d.x", "Number") === true;
base.isFulll("d.y") === false;

Fit

validator of value with middleware iterator. Also accept path as first argument

base.fit("a", (next, value, valueBefore)=>next(value > 0 ? 0 : value));

after defining new validator base will reprocess last input.

Watch

run me when variable under path has changed

base.watch("a", (get, changes)=>console.log(get()));

after any change at desired path will be called this function. Passing two arguments. Both are functions. get() will return value at same path and changes() will return list of sub changes;
