We will use this data to generate the invoice. To have a starter project to start, I prepared a Node.js project that populates MongoDB with orders and exposes two to retrieve these orders. The picture below shows the structure of our database and the relationship between the collection: The entity-relationship diagram of the system Set up the project Check out my previous tutorial if you want to know how to connect a Node.js application to MongoDB. The data are stored in a MongoDB database, and we will use Node.js to connect through and retrieve the order to generate an invoice. Our goal is to generate an invoice for the order in PDF format. The use caseĪs the use case, let's take an e-commerce website where a customer can browse products and make an order for the products he is interested in.Īn order requires a billing and shipping address which can be different or the same. In this tutorial, we will see how to generate a PDF using Node.js to handle the logic, a view template engine called Handlebars to design and style the report and finally, use a headless browser called puppeteer to print PDFs of the view generated. Take too much to draw the design of the report since we are doing it in imperative.It doesn't give the freedom to customize the design.

CSS styling is the most crucial part if you want a nice report.When it comes to generating a summary that will be exported in PDF format, many libraries help to achieve this task, but there can be limited in features like: Generating PDF files from a web application is one of the most tedious tasks nowadays.
