![]() 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. Let's take a look at some of the features it offers. 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. Note: Before attempting to overwrite an existing PDF file, it must be free. 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. I had a two column layout where the text was getting cut off mid-text.The PDF format is one of the most common document formats for transferring information. None of the solutions I found worked for me, but something else did. I scoured the internet for a couple of weeks, trying to overcome this issue. We have to make it easy for the library to detect this by removing as much odd css in there as possible, so it's as simple as possible to calculate down to the pixel where the content lies. I believe ultimately the code is trying to guess as best as it can exactly how many pixels high each page is, and where exactly (down to the pixel) is your content. ![]() Then the page-break-inside: avoid was working after that as expected. It started working and not cutting off either images or tables mid-row once I removed that. I made so many tweaks trying to get it to work so I can't be 100% sure, but I believe the issue was it set to 'display:table' with margin: 0 auto and a specific width on the main outer div. Then I tweaked css that was on the root div of my html, and it fixed it. I kept tweaking css to play around, trying to throw in page-break avoids everywhere, not having much progress. This is old but hopefully will help someone - I was having the issues too, tried everything - even resorting back to old versions mentioned (12.1) but to no avail. HTML documents such that it contains many lines on which pages can be Solution to this problem, until this is solved try organising your Page-break-inside property to remedy this somewhat. If you are using the patched version of QT you can use the CSS Will cut a line into to pieces display the top half on one page. Of text where one is vertically shifted by half a line. ![]() ![]() Basically webkit will render everything into one long page,Īnd then cut it up into pages. The current page breaking algorithm of WebKit leaves much to beĭesired. According to some documentation I found (see Page Breaking), this is a known issue and suggests using CSS page breaks to insert page breaks (assuming you are using patched version of QT): ![]()
