Generate pdf with Serverless API
I started with PDFKit and jsPDF to generate pdf but it became difficult with complex layouts. jsPDF supports generating a PDF from an HTML element or string but it does not work in node environment.
Finally, I ended up using puppeteer to generate a PDF page from an HTML string. I created a simple code using Nestjs framework, including a POST endpoint which will generate a PDF from HTML string input.
Recently, I found Google Chrome for AWS Lambda as a layer. That means I can setup a serverless api with Lambda running puppeteer. THAT IS ALL WE NEED!.
You can check out the set up with AWS SAM CLI on my github repo: https://github.com/haku-d/html-2-pdf-lambda
