Web Services Command Cheatsheet
13 cheatsheets covering nginx, Reverse Proxy, location, Configuration, curl and more
The web chain runs from reverse proxy to page layout: Nginx handles forwarding and TLS, CSS decides how things look, and HTML semantics sit in between. These 13 sheets cover Nginx, Next.js, Svelte, Tailwind, Flexbox, Grid, Sass, HTML meta tags, curl and frontend fetch. When to use: on a 502 or a CORS failure, start with the Nginx and curl sheets; when fixing layout, first decide whether you want Flexbox or Grid, then take the syntax from Tailwind or Sass; slim down the document head via html-meta. After touching any config, run nginx -t before reloading — shipping a syntax error costs far more than typing one extra command.
