Javascript Wrapper and Helper Functions for the NHTSA VPIC API

A universal (browser/server) javascript wrapper for the National Highway Traffic Safety Administration (NHTSA) Vehicle Information API (VPIC).

The VPIC API is primarily used for decoding useful information from a Vehicle Identification Number (VIN) in the United States and Canada. It can also be used to get all models of a make, to decode WMIs, get all makes for a certain year, and more.

Node Install

NPM

`sh [npm] $ npm install @shaggytools/nhtsa-api-wrapper


### Yarn

```sh [yarn]
$ yarn add @shaggytools/nhtsa-api-wrapper

Pnpm

`sh [pnpm] $ pnpm add @shaggytools/nhtsa-api-wrapper


## Node Quick Start

Decoding a VIN is as easy as importing the `DecodeVinValues` function and calling it
with a VIN.

Make sure to first install via your favorite package manager or use a CDN.

```javascript
import { DecodeVinValues } from '@shaggytools/nhtsa-api-wrapper'

const results = await DecodeVinValues('WA1A4AFY2J2008189')

/* 
results = {
  Count: 136, - number of Results objects returned
  Message: 'Results returned successfully ...',
  SearchCriteria: 'VIN:WA1A4AFY2J2008189',
  Results: [ {...} ] - an array with single object of type DecodeVinValuesResults
}
*/

/* You can also use destructuring to get the Results object */
const { Results } = await DecodeVinValues('WA1A4AFY2J2008189')

/* This endpoint only returns a single object in the Results array
   The first object in the array is the decoded VIN data */
const decodedVehicle = Results[0] // equals an object of type DecodeVinValuesResults

For a full example response see: DecodeVinValues

All available endpoints can be found here: VPIC API Endpoints

Browser Install

You can use the package directly in html script tags using a CDN. There are several options for CDN providers.

For targeting modern browsers, you can use the ESM versions with <script type="module"> and import statements.

For older browsers, you can use the IIFE versions with <script src="https://..."> to import the package. Then use the package in a separate html script via the browser global NHTSA. This global variable is only available when using the IIFE or UMD versions.

UNPKG CDN

All package files and types are hosted on the UNPKG CDN found here:
