#InvoiceRenderer

#Import

typescript 
1import { InvoiceRenderer } from "@alepha/commerce/invoicing";

#Overview

Turns an invoice row into something a customer can keep.

#Why the default is HTML and not PDF

Every PDF library is a heavy dependency, several do not run on Cloudflare Workers, and none of them is the right choice for every deployment. Forcing one into this package would tax every consumer for a format some of them do not need - a POS prints a receipt on a thermal printer and never makes a PDF.

So the default renders semantic, print-ready HTML - which browsers turn into a PDF on demand, and which is legally sufficient - and a consumer that wants a real PDF substitutes this provider:

ts 
1alepha.with({ provide: InvoiceRenderer, use: PdfInvoiceRenderer });
