Linear Feet

Linear Feet is a simple NPM package written in typescript for calculating the linear feet of a skid or set of skids, as commonly used in United States LTL (Less than Truck Load) shipping.

Installing

npm add linear-feet

Examples:

import {calculate, Skid} from "linear-feet";

const mySkids = {
    length: 45, //45 inches long
    width: 20, //20 inches wide
    height: 45, //45 inches tall
    quantity: 3, //3 skids match these dimensions
    stackable: false //This skid cannot be stacked.
};

 //Prints 2.8125 linear feet
console.log(calculate(mySkids) + " linear feet");

//There's also a handy class for creating skids!
const myOtherSkid = new Skid(1, 60, 45, 45, false);

//The calculate method also accepts an array of skids
//These skids combine for 5.3125 linear feet
let myArray = [mySkids, myOtherSkid];
console.log(`All skids total ${calculate(myArray)} linear feet`); 

//The options object allows you to modify 
//how the linear feet are calculated
const lft = calculate(mySkids, {maxSkidsAcross: 3});

If you're using typescript, you can also use the iLftOptions and iSkid interfaces:

import {calculate, iLftOptions, iSkid} from "linear-feet";

const mySkids: iSkid = {
    quantity: 3,
    length: 45,
    width: 20,
    height: 45, 
    stackable: false 
};

const shippingOptions: iLftOptions = { maxSkidsAcross: 3 };

console.log(calculate(mySkids, shippingOptions)); 

Linear Foot Options

The options object has the follow properites:

maxStackableLength: Skids greater than this length will never be considered stackable. Default is 144.

maxStackableHeight: Skids taller than this will never be considered stackable. Default is 48.

maxStackableWidth: Skids wider than this will never be considered stackable. Default is undefined (no limit).

truckWidth: The width in inches of the truck/trailer for the purposes of determining how many items can sit wide. Default is 96.

truckHeight: The height in inches of the truck/trailer for the purposes of determining how high items can be stacked. Default is 106.

maxSkidsAcross: Maximum number of skids that can be placed side-by-side, regardless of truck width. Default is undefined (no limit).

maxSkidsStackable: Maximum number of skids that can be placed on top of each other, regardless of truck height. Default is 2.
