Ask HN: Modern day web development for someone who last did it 15 years ago

TL;DR -> Want to build a relatively simple responsive website like say Hacker News with Authn support (custom and Google OAuth). What is a minimal set of JS/CSS frameworks, templating engine, deployment tools, IDE I need? Details: I am a professional Software Engineer (Google) and well versed in "Backend" Infra stuff and creating APIs. But when it comes to building anything with GUI, I am completely lost in the maze of modern day web dev! Last time I built a website was a bunch of mostly static pages (all hand generated - no templates either) with some JS plugins for a top bar nav. Life was simple with a simple SFTP to the webserver (Geocities or similar!) for hosting. Of course over time, web development has become much more complex (primarily because Websites do much more now a days than they used to), and I see a plethora of frameworks, transpiled languages, etc such as: Gulp, Typescript, JSX, Dart, Angular, React, Bootstrap, Babel, Wordpress, Drupal, Flutter, NPM,
