text( 'Some text with an embedded font! ', 100, 100) In my experience, the AWS SDK is garbage when it comes to working with streams, so I usually use request. # Embed a font, set the font size, and render some text doc. There's no need to use an intermediate memory stream 1 just pipe the pdfkit output stream directly into a HTTP upload stream. You can change it to false when calling the text() function: pdfDoc.text( 'very long text '.PDFDocument = require 'pdfkit ' # Create a document doc = new PDFDocument # Pipe its output somewhere, like to a file or HTTP response # See below for browser usage doc.

In other words, the lineBreak option is true by default. The pdfkit module automatically wraps lines so that they fit between the margins, or in the width provided (when writing text in columns).

Now go into this folder and install the dependencies using yarn: cd form-to-pdf. PdfDoc.text( 'From Mon-Sat we will have a 10% discount on selected items!', 150, 150) Then use this to generate a basic Express app: express -viewpug form-to-pdf. This would also allow you to, for example, print text over other text: const PDFDocument = require( 'pdfkit')

This is useful because it allows you to fine-tune the positioning of text, especially since PDF documents have a universal look regardless of the machine/OS they are opened on. You can change where the text is printed within the current page, by adding the x and y coordinates of the location where you want the text to be placed as arguments to the text() function.įor example: pdfDoc.text( 'Text positioned at (200,200)', 200, 200) Positioning Textīy default, the pdfkit module keeps track of where text should be added to the document, essentially print each call to the text() function in a new line. If you don't want Koa to touch the response, you can use ctx.respond false, which also makes OP's example work perfectly. Writing to Node.JS HTTP objects managed by Koa is likely to conflict with Koa, as it does in this case. There are two ways to use PDFKit in the browser. For more, see the demo folder and the PDFKit programming guide. Let's take a look at some of the features it offers. catamphetamine Koa can be seen as a wrapper around the Node.JS HTTP APIs. The PDF output from this example (with a few additions) shows the power of PDFKit producing complex documents with a very small amount of code. Of course, pdfkit allows us to do much more than just add unformatted text to a document.

I.e - all windows with that PDF file must be closed or the program will throw an error. Hapi - A rich framework for building applications and services.

Meteor - A platform that has strong features such as live page update, sync and hopt code pushes. Totaljs - Friendly responsive design web application framework for node.

Note: Before attempting to overwrite an existing PDF file, it must be free. Koa - A framework which aims to be a smaller, more expressive, and more robust foundation for web applications. When we run the code, a PDF file called SampleDocument.pdf is created in the root folder of our project: $ node index.js Of course, we'll want to end() the stream in the end.

Once created, we can add contents to it, via the text function. We're using the pipe() function to do this and save the resulting SampleDocument.pdf into our root directory. If you're not familiar with how streams work, check out our Introduction to Node.js Streams. We'll be piping that stream into a writeable stream to save the file. PdfDoc.pipe(fs.createWriteStream( 'SampleDocument.pdf')) įirst, we import the required modules, after which, we instantiate the PDFDocument. We'll pipe the contents of our PDF file into a fs's writeable stream to save it. To create a PDF document, we will need to import the fs (file system) module as well. To use the module in the project, we'll import it via require(): const PDFDocument = require( 'pdfkit') Then, let's install pdfkit: $ npm install pdfkit Let's create a project directory, cd into it and initialize the Node project with default settings: $ mkdir pdfkit-project $ cd pdfkit-project $ npm init -y PDFKit is a JavaScript PDF generation library for Node.js that provides an easy way to create multi-page, printable PDF documents.

In this article, we will discuss how to generate PDF files in NodeJS using the NPM package pdfkit. In dynamic web applications, you might need to export data into a document and PDF is usually a popular option. The PDF format is one of the most common document formats for transferring information. If need to get wkhtmltopdf output you should pass verboseTrue to API calls: omurl ('', 'out.pdf', verboseTrue) Due to wkhtmltopdf command syntax, TOC and Cover options must be specified separately.
