Node.js CI CodeQL

About:

This package was forked from MadisonReed/usps-webtools, but it has been modernized with Typescript and Promises (async/await). Note: Version 2 is a drop-in replacement for MadisonReed/usps-webtools, it produces the same output. Version 3 uses the same output from USPS, with the exception of Address1 and Address2 being switched, per social norms.

Installation:

npm install usps-webtools-promise

Usage:

Initializing the usps model with a user id.

Example:

const USPS = require('usps-webtools-promise').default;
// or
import USPS from "usps-webtools-promise";

const usps = new USPS({
  // USPS returns ALL CAPS, this boolean turns on Proper Caps for both Street lines and City. This is an optional item. Defaults to true.
  properCase: boolean,
  // Staging will run all functions on the USPS Staging servers instead of Production. Defaults to false.
  staging: boolean,
  // This can be created by going to https://www.usps.com/business/web-tools-apis/ and registering for an id
  userId: 'USPS User id',
});
