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)
#PDFKIT PIPE KOA 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. 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 ( ). The documentation can be found at the website ( ). The JavaScript PDF document generation library for Node.js used in this example is PDFKit ( ). There are also backend systems such as Enterprise Resource Planning (ERP), Supply Chain Management, Blockchain network etc. A business application in BTP typically includes a user interface, microservices that contain business logic, and technical operations. SAP Business Technology Platform (BTP) provides a fast and easy way to create, run, manage, and scale business applications in the cloud.
#PDFKIT PIPE KOA HOW TO#
This blog post shows examples of how to generate a PDF document in business applications using Node.js. Often enough, a business application needs to generate PDF documents based on business data and images (such as receipts, certificates, etc.). HTML does this out of the box because it’s markup language.Portable Document Format (PDF) is one of the most common document formats used for electronic documents in businesses due to its nature of being read-only, having rich formatting styles, and being compact in size, etc. This would generate an invoice that looks like this:įormatting through code can be pretty complex because you have a lot of numbers you have to keep in mind. TheOutput.pipe(fs.createWriteStream(fileName))
TheOutput.text('Some awesome example text'. The text method actually takes in an optional option property after the string that can allow us to do things like bold, underline, oblique (“italicize”), or strike. We would need to write quite a bit more code to format it. TheOutput.text('Some awesome example text')Īfter that we then get a pdf that would look like this:Īgain, that’s still pretty bland. We can add text using the text method like this: const PDFGenerator = require('pdfkit') TheOutput.pipe(fs.createWriteStream('TestDocument.pdf'))Īt this point, we would have a really useless pdf file that doesn’t contain anything. pipe to a writable stream which would save the result into the same directory
We then need to instantiate the library and then pipe it to the writeable stream. const pdfGenerator = require('pdfkit')Īfter that, we can start to simply use it with the core file system (commonly called fs). Using PDFKit in an existing project is pretty easy.įrom the command line / terminal we need to add it is a dependency npm i pdfkitĪfter that we can use it as a module in our project by simply requiring it. PDFKit is a library that I’ve used a few times for generating very simple invoices that a template wasn’t used for. In this post, we will cover using a library to generate the pdf using just JavaScript. We are going to cover both methods though because there are times I prefer to write a lot of code and do it.

Basically – I download the existing template and sales or marketing provides me the updates. I normally prefer to use a template that is HTML based to create pdf files because this potentially allows marketing or business users to make some of the needed changes without necessarily requiring code changes to happen. The first way is to use a PDF generation library that uses straight JavaScript/Nodejs and everything is untemplated or the other way is to use something templated in a language like HTML and then generate the pdf from it. There are two major ways to approach creating a PDF file from Nodejs. It’s a really common request for businesses to be able to export a document or data into a really well-formatted PDF file whether it be an invoice or a report. The PDF format is one of the most common file formats for transmitting static information.
