Thus WebKit based rendering libraries faces the bigger problem to render all the HTML5 CSS properties and impact your final output.

PDF kit is also good but it also fails at supporting all of HTML fonts and components along with a mix of its own markup definition. Their lack of proper API defeats the optimizations which a bare Webkit rendering might offer.Ģ. Which is going to be inefficient for most practical purposes. They all work as directly reading from a file and saving to a file.These available WebKit based rendering libraries have shortcomings. There are several WebKit rendering libraries such as wkhtml and its derivatives. Webkit based rendering is lighter on memory and faster than running a headless browser like PhantomJs or Puppeteer. Webkit rendering is basically tearing off what a browser does under its hood and then printing the rendered output as PDF. WebKit Rendering of your HTML/XML Markup.There are usually two ways to generate PDFs from an HTML template. So I decided to dig a little deeper than just the first npm results page and came up with the following learning. This custom markup writing took away the freedom from the developer to design even slightly complicated designs or make the whole process cumbersome. These libraries create DOM in memory by hard coding the design architecture in Javascript using their own markup definition. Some of these libraries make the act of PDF generation as markup definition.Due to deprecation in their inherent rendering engines, they only support selective HMTL UI components and often miss out on fonts. Support for only a minimal number of UI components.Finally, none of them actually exposed the stream object which one can directly pipe in the response object of an HTTP server.

These converters also don’t provide any simple approaches to update those HTML files in realtime as per the app logic to dynamically generate the report. This is an I/O expensive approach as the HTML file had to be first read from the local disk and then written as PDF back on the disk, which of course needs to be piped back in response. These converters are designed to read the file stream from a local directory and to write stream back on the disc.

The first thing that sounded like the right thing to was that we just need a way to convert HTML code into PDF, right? So did a quick npm seach
