## What it is
Angular Flex-Layout is a TypeScript library providing a declarative Flexbox-based layout API and a responsive engine with mediaQuery observables for Angular applications. The Angular team no longer publishes new releases, so it is effectively deprecated in favor of modern CSS approaches.

## Use cases
- build responsive flexbox layouts in Angular apps
- apply different layouts per breakpoint with a responsive API
- replace manual CSS flexbox with declarative HTML attributes
- observe media query changes in Angular components
- control element visibility and sizing across devices

## When to choose
- you maintain a legacy Angular app already using @angular/flex-layout
- you need a declarative flexbox API with built-in responsive breakpoints in Angular

## When to avoid
- starting a new Angular project - the team recommends modern CSS instead
- you need actively maintained layout tooling with new releases
- your project uses frameworks other than Angular
