Puppeteer vs SlimerJS: What are the differences?
Puppeteer: Headless Chrome Node API. Puppeteer is a Node library which provides a high-level API to control headless Chrome over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome; SlimerJS: A scriptable browser for Web developers. It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc.
Puppeteer and SlimerJS can be categorized as "Headless Browsers" tools.
Puppeteer and SlimerJS are both open source tools. Puppeteer with 53.2K GitHub stars and 4.97K forks on GitHub appears to be more popular than SlimerJS with 2.87K GitHub stars and 288 GitHub forks.
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 Phantomjs is already more or less outdated as technology.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.
