NODEJS PDFKIT HTML TO PDF GENERATOR

For generating this data I have used an awesome tool called It is an online data generator tool. You can get the mocked JSON stub data from here. Second, in the same folder, create a new file called data.json and have some mocked data in it. This will initialize an empty project for you. In your terminal type in the following: npm init -y This will help you understand this tutorial. You don’t need to, but you can also watch an introductory video (my first ever made) that talks about the basics in reading, writing, and deleting a file in NodeJS.

Node Package Manager (NPM) version 6.9.0.

SOURCE CODE OF TUTORIALīefore we begin, please ensure that you have at least the following installed on your machine That will prove more useful & you’ll understand more. You don’t have to write anything, but you should write code along with this tutorial.

Making them into npm scripts, to be used later ?Īlso before we begin here is the entire source code of the tutorial, for everyone to follow along.

Creating a PDF file of that HTML file generated using Google puppeteer.Learning about writing a file using fs.writeFileSync.Learning about deleting a file by using fs.unlinkSync.Learning about checking if a file exists or not using fs.statSync.Creating an HTML table with a little bit of styling with generated data in it, using an automated node script.Generating stub data (for invoices) using an online tool.So to again give a brief overview, things we will cover: In the process we’ll learn about puppeteer.launch() and understand a bit about page() & pdf().

We’ll look at how to generate a nice PDF file based on our generated HTML table file. You can even do form submissions via your NodeJS server.Īgain puppeteer is a huge tool, so we will cover just a small but a very cool feature of puppeteer. Like getting a website’s screenshots, crawling websites, and generating pre-render content for single page applications.

So it’s basically a tool that lets you do all the cool browser related things on server. It can also be configured to use full (non-headless) Chrome or Chromium. So what is puppeteer? Well as per the docs, they say: Puppeteer is a Node library which provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol.

Writing data to a file: fs.writeFileSyncĪnother thing we will cover in this article is Google Puppeteer which is this really cool, slick tool created by some awesome folks at Google.

In this article, however I will only discuss 3: Now file system is a humongous utility in NodeJS that has a lot of fancy features. Which is just a fancy way of saying that file system is a way in Node to interact with files for both read and write operations. Today I wanted to uncover the power of Node’s built-in utility tool called fs ( file system)Īs per the fs docs: The fs module provides an API for interacting with the file system in a manner closely modeled around standard POSIX functions. Node is a very powerful language and it can do a lot of things. Understanding NodeJS internally can be a little bit daunting (I know it was for me once).
