#NODE JS PDFKIT PDF#
It's not too hard to add a finish event handler to the stream you set up to pipe to if you need that, and it will prevent future headaches. Pdfkit PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printable documents easy.
#NODE JS PDFKIT CODE#
This could cause subtle and hard to debug race conditions in people's code who assume that everything is really done when that callback is called.įor this reason, my vote is to keep PDFKit the way it is now and not to add a callback to doc.end.
So, we could add a callback to the end method, but it might get called before the stream is actually done writing. It may be some time later that the writable stream actually flushes its internal buffers out to the actual destination. Since PDFKit has no access to the actual writable stream it is being piped to (PDFKit itself is a readable stream, and you set up the writable part), it only knows when it has finished pumping out chunks to whoever might be reading. PDFKit is available under the MIT license.The problem with adding a callback to the end method is that PDFKit doesn't actually know when all of the data has been flushed to whatever stream you're writing to (file, http response, etc.).

#NODE JS PDFKIT INSTALL#
If you forget to install it, Browserify will print an error message. PDFKit's package.json, so it isn't installed by default for Node users. Below is the step by step procedure for creating the example project. Which is used to load built-in font data into the package. Let’s create a small example to export multiple student data into a PDF file. Note that in order to Browserify a project using PDFKit, you need to install the brfs module with npm, You can see an interactive in-browser demo of PDFKit here. text ( 'Some text with an embedded font!', 100, 100 ) // Add an image, constrain it to a given size, and center it vertically and horizontally doc.

See fontkit for more details on advanced glyph layout support. If you want to generate pdfs dynamically then you can also try out html-pdf library in node which allows you to create a pdf from html template and add dynamic data in it.
