Trying to build a better world. Understanding NodeJS internally can be a little bit daunting I know it was for me once. Node is a very powerful language and it can do a lot of things. Which is just a fancy way of saying that file system is a way in Node to interact with files for both read and write operations.

Now file system is a humongous utility in NodeJS that has a lot of fancy features. In this article, however I will only discuss Another thing we will cover in this article is Google Puppeteer which is this really cool, slick tool created by some awesome folks at Google.

The join '' part is important here, because I want to concatenate all of my array into a string. It takes in 2 parameters: one is the build path string and the html content string and generates a file if not created; and if it is created, it overwrites the already existing file.

Stack Overflow works best with JavaScript enabled.In one of our recent projects users had to generate a PDF invoice with the list of orders they did on the platform we have built using Elixir.

With this article I want to share with you the steps I followed, the decisions I have made until I reached the final solution and why I ended up creating our own module. Hopefully the article can also help you solve a similar problem and make you contribute to the package we created.

I started by researching for existing solutions and quickly discovered that without a doubt the best solution to generate a PDF file was to have it designed in HTML and then convert it to PDF. At first I was very satisfied with the output generated, being the only problem the HTML table entity containing the orders being badly divided between multiple pages.

I ended up calculating how many table rows I could fit on each page, but as I kept evolving the design I had to redo the calculations over and over again. HTML table entity render behaviour on Puppeteer. The second issue I encountered was with unicode characters, like Chinese characters. The third and most annoying issue was that wkhtmltopdf uses the machine display to generate the PDF file. For instance, being on an Macbook Retina xpx 13" display I needed to exaggerate the document size in the CSS style i.

For example, I needed to have font-size: 42px instead of font-size: 12px that was what I would normally use. Since I needed to do some calculation previously to show the content properly, this was unbearable to maintain.

I tried to tweek the display size with the --viewport-size option, but without success. You can find somes issues related to that in their repositorythat contain over issues still open. Taking the suggestion of Daniel Ruf related to the display size issues, I end up exploring puppeteera Node API that allows you to take screenshots from webpages as well as generate PDF files using a version of Google Chrome browser in headless mode.

With this software, I finally could have the same PDF design replicated in both my laptop and on the server. Globally the PDF rendered was better than wkHtmlToPdfbeing the only issue so far the file size which is 10 times higher than the size of the file generated by wkHtmlToPdf.

This also allowed me to implement the header and footer in HTML, and after some tweaking with margin parameters. I could finally generate a PDF file without having to do the previous calculations on the template items. This feature is available in the wkHtmlToPdfbut I just noticed that after exploring the puppeteer options.This is one of those frustrations post where I just spent hours working on something and I finally managed to have a working solution.

I learned quite a bit but I feel like it should not have taken me that much time I tried a lot of different things, and it's more than likely my solution is not the most elegant, or fast, but fuck it, it works. I consider this post to be a place where I can store this solution, juste in case I forget it in the future. I'll know where to look. Let's jump into the actual solution.

Here is the back-end things. There is a whole express application and everything. I juste show you the controller where the two methods reside for this PDF problem.
