How to Generate Barcodes in Node.js Using Express, EJS, and JsBarcode
Generating barcodes programmatically is a frequent requirement when building inventory systems, invoicing modules, or shipping portals. While many developers rely on heavy client-side libraries or external APIs, you can easily build a server-side barcode generator using Node.js, Express, EJS, and the Canvas package . In this tutorial, we will walk through a complete implementation of a dynamic barcode web app that accepts user input via a form, generates a barcode image server-side using JsBarcode and canvas , and renders it instantly on an EJS template. Prerequisites & Tech Stack Make sure you have Node.js installed on your system. We will use the following packages: Express : Fast, unopinionated web framework for Node.js. EJS : Embedded JavaScript templating engine. Canvas : To provide a headless HTML5 Canvas implementation in Node.js. JsBarcode : A lightweight barcode generation library. Step 1: Initialize Project and Install Dependencies Open your terminal, create a new direc...
