AaronHarris / truncate-json.js

Last active January 7, 2019 23:21

A module that shortens JSON to a number of bytes while keeping syntactically valid JSON. Useful for when apis can only accept a certain byte length for input. Only works for NODE but can be ported to browsers. WIP.

	function getBytes(string) {
	return Buffer.byteLength(String(string), 'utf8');
	}

	function trimToBytes(string, diff) {
	return Buffer.alloc(diff, string, 'utf8').toString();
	}

	// This is only intended atm for flat objects with string values
	// Does not handle edge cases

JavaScript Stump - the Ultimate Singleton: This describes a function object that no matter whether you call it, instantiate it, or access or modify a property, it always returns itself.

	var proxy, handler;
	handler = {
	has(/target, prop/) {
	return false;
	},
	get(target, prop, receiver) {
	if (prop in target) return target[prop];
	return receiver;
	},
	set(/target, prop, value, receiver/) {
