Answered from the vendors’ own pages
HTMX: How big is the HTMX JavaScript library?
HTMX is only 16 kilobytes minified and gzipped with zero external dependencies.
SourceYarn: What is Yarn's main advantage over npm?
Yarn downloads packages in parallel, significantly reducing installation time. It uses a yarn.lock file for deterministic installs, ensuring identical package versions across machines and preventing version conflicts common with npm.
SourceHTMX: Can HTMX work with JSON APIs?
While HTMX is optimized for HTML responses, it can work with JSON through additional configuration and response handling.
SourceYarn: Can I use Yarn in offline environments?
Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.
SourceHTMX: Does HTMX support real-time features like WebSockets?
Yes, HTMX includes support for WebSockets and server-sent events for real-time bidirectional communication.
