AWS OpsWorks vs PhantomJS: What are the differences?
AWS OpsWorks: Model and manage your entire application from load balancers to databases using Chef. Start from templates for common technologies like Ruby, Node.JS, PHP, and Java, or build your own using Chef recipes to install software packages and perform any task that you can script. AWS OpsWorks can scale your application using automatic load-based or time-based scaling and maintain the health of your application by detecting failed instances and replacing them. You have full control of deployments and automation of each component ; PhantomJS: Scriptable Headless WebKit. PhantomJS (www.phantomjs.org) is a headless WebKit scriptable with JavaScript. It is used by hundreds of developers and dozens of organizations for web-related development workflow.
AWS OpsWorks and PhantomJS are primarily classified as "Server Configuration and Automation" and "Headless Browsers" tools respectively.
Some of the features offered by AWS OpsWorks are:
- AWS OpsWorks lets you model the different components of your application as layers in a stack, and maps your logical architecture to a physical architecture. You can see all resources associated with your application, and their status, in one place.
- AWS OpsWorks provides an event-driven configuration system with rich deployment tools that allow you to efficiently manage your applications over their lifetime, including support for customizable deployments, rollback, partial deployments, patch management, automatic instance scaling, and auto healing.
- AWS OpsWorks lets you define template configurations for your entire environment in a format that you can maintain and version just like your application source code.
On the other hand, PhantomJS provides the following key features:
- Multiplatform, available on major operating systems: Windows, Mac OS X, Linux, and other Unices.
- Fast and native implementation of web standards: DOM, CSS, JavaScript, Canvas, and SVG. No emulation!
- Pure headless (no X11) on Linux, ideal for continuous integration systems. Also runs on Amazon EC2, Heroku, and Iron.io.
"Devops" is the top reason why over 27 developers like AWS OpsWorks, while over 12 developers mention "Scriptable web browser" as the leading cause for choosing PhantomJS.
PhantomJS is an open source tool with 26.9K GitHub stars and 5.7K GitHub forks. Here's a link to PhantomJS's open source repository on GitHub.
Key Location, Ghost Inspector, and Tailor Brands are some of the popular companies that use PhantomJS, whereas AWS OpsWorks is used by Third Iron, DeveloperTown, and TENDIGI, LLC. PhantomJS has a broader approval, being mentioned in 78 company stacks & 47 developers stacks; compared to AWS OpsWorks, which is listed in 73 company stacks and 18 developer stacks.
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.
