#PDFKIT NPM INSTALL#
To use this options you should install static binary from wkhtmltopdf site or you can use this script. Warning! Version in debian/ubuntu repos have reduced functionality (because it compiled without the wkhtmltopdf QT patches), such as adding outlines, headers, footers, TOC etc. MacOS: $ brew install homebrew/cask/wkhtmltopdf Install python-pdfkit: $ pip install pdfkit (or pip3 for python3)ĭebian/Ubuntu: $ sudo apt-get install wkhtmltopdf This is adapted version of ruby PDFKit library, so big thanks to them!

This function gets an image from a web URL using the axios library and displays it in the PDF document. "use strict"Ĭonst _REQUEST_UTIL = require("./RequestUtil") Let ig = new _INVOICE_GENERATOR(_kINVOICE_DATA) Ĭreate a class (InvoiceGenerator.js) for calling the PDFKit library to generate the PDF document. ItemDescription: "Best Run desktop computer", ItemDescription: "Best Run laptop computer", "use strict"Ĭonst _INVOICE_GENERATOR = require("./InvoiceGenerator") It is passed as an argument into InvoiceGenerator.js to generate the PDF document. The sample invoice data is defined as a JSON object. _REQUEST(requestPayload, function(err, response)Ĭreate the main function (GenInvoice.js) to provide the sample invoice data to be displayed in the generated PDF document. Return new Promise(function(resolve, reject) I can explain it by giving an example- Suppose a request come to the application to generate a pdf, is starts processing and after processing it.
#PDFKIT NPM CODE#
In the sample code of this article, the doRequest function is called to get the content of an image file from a web URL. But my application is very slow, below are the reasons : What problem I am facing : It is working in sync manner. The doRequest function returns a Promise object which eventually will return a resolved state or a rejected state. npm initĬreate a Node module (RequestUtil.js) to handle requests. The sample code shown in this article is partly based on another article Generating a PDF in Nodejs ( ).įrom the command line or terminal, add the dependency libraries after project initialization. However, for demonstration purpose, this article shows how these two libraries can be used to load an image from a web URL and display it in the PDF document. During implementation, you only need either Request or axios for requests/responses. Other libraries used in this example are Request ( ) and axios ( ).
