Astro is an all-in-one web framework powered by your favorite UI components and libraries
Are you not sure what a framework is? Or are you confused by there being different UI components and libraries?
Either way both are pretty easy to look up!
all-in-one (new oxford dictionary): "combining two or more items or functions in a single unit"
Astro
- can do SPA
- can do MPA
- can use a variety of different view libraries
- can write endpoints to serve any data
So is your ill-defined issue with "all-in-one" the fact that it doesn't support every single view library?
