server-cli-only

The `server-cli-only` package, currently at version 0.3.2, acts as a build-time failsafe to prevent specific modules from being bundled into client-side (browser) code. Its primary function is to restrict imports of designated modules exclusively to server-side environments such as React Server Components, Node.js, Bun, Deno, and various edge runtimes (Vercel, Netlify, Cloudflare). Unlike the `server-only` package, which strictly targets the 'react-server' runtime, `server-cli-only` expands its allowed runtimes to encompass a broader range of server and CLI execution environments, including those defined by WinterCG specifications. This ensures sensitive code or data remains server-side, throwing build-time errors if inadvertently imported into a browser context or an unknown runtime, thereby preventing potential security vulnerabilities and unexpected client behavior. The package maintains a stable, low-frequency release cadence as it primarily focuses on a core, foundational restriction mechanism.
