It’s ideally suited for tasks like dynamically generating PDF invoices for your web server. PDFKit allows us to generate PDF documents in Node.js and the browser. In any case, once you add the table headers and footers, you’ll have a full invoice generated on demand using pdfkit in Node.js. You can see the complete example code on GitHub. To keep the code examples in this post concise, we stripped out table headers and footers, along with some utility functions for formatting currency and dates. For now, start with generating the header and footer of the invoice: Then create stub methods for the four sections above. To create an empty PDF document, use the PDFDocument constructor of pdfkit.
Your invoice will consist of four visual parts:Ī header that contains information about your company, including your company’s logo. Start by creating a function, createInvoice(invoice, path), which uses the invoice object to create a valid PDF invoice and then saves it to a file located at path. With this data model, you’re now ready to generate a PDF file.
invoice_nr is used to identify the invoice. The subtotal key contains the sum of all items in cents, and the paid field allows you to specify how much was already paid for this invoice. The items key contains an array of all items you want to print on the invoice (the amount is the sum for all pieces of this item in cents). In the above object, there’s a shipping key that contains all the shipping information to print on the invoice.
