Supplier Notation Drift
Suppliers export CSV feeds with hyphens (81.50110-0144), dots, or spaces. Standard SQL exact matches miss up to 60% of inventory cross-references.
Daimler 'A' Prefix Gap
Mercedes-Benz parts are frequently indexed as A 000 420 00 20, but mechanics search for 0004200020. The normalizer reconciles both schemas.
Multi-Supplier Price Matching
Built as the core comparison engine for CrazyPartSnatcher, matching Bosch, Hella, Brembo, Mahle, and Febi Bilstein offers.
TypeScript / JavaScript Quickstart
import { normalizeOem, generateSearchVariants, buildPartSearchUrl } from '@crazypartsnatcher/oem-normalizer';
// 1. Strip punctuation & unify to uppercase alphanumeric
const clean = normalizeOem('81.50110.0144');
console.log(clean); // '81501100144'
// 2. Generate search variations for SQL / Elasticsearch index
const variants = generateSearchVariants('A0004200020');
console.log(variants);
// ['A0004200020', '0004200020', 'A 000 420 00 20', '000 420 00 20', ...]
// 3. Build comparison link on CrazyPartSnatcher
const url = buildPartSearchUrl('81.50110.0144');
console.log(url); // 'https://www.crazypartsnatcher.com/shop?q=81501100144'
