I am using Node 12 for server scripting and have a function to generate PDF and send it to a browser. Currently, we are using PhantomJS to generate a PDF. Some web post shows that we can achieve PDF generation using Puppeteer. I was a bit confused. Should we move to puppeteerJS? Which one is better with NodeJS for generating PDF?
You better go with puppeteer. It is basically chrome automation tool, written in nodejs. So what you get is PDF, generated by chrome itself. I guess there is hardly better PDF generation tool for the web. Phantomjs is already more or less outdated as technology. It uses some old webkit port that's quite behind in terms of standards and features. It can be replaced with puppeteer for every single task.
I suggest puppeteer to go for. It is simple and easy to set up. Only limitaiton is it can be used only for chrome browser and currently they are looking into expanding into FF. The next thing is Playwright which is just a scale up of Puppeteer. It supports cross browsers.
