The **serverless‑plugin‑ifelse** adds conditional logic to a Serverless framework YAML file, letting developers include, exclude, or modify any configuration attribute (functions, provider settings, etc.) based on custom `if/else` expressions. It is aimed at Serverless users who need more flexible, stage‑ or region‑specific configuration than the built‑in variable substitution provides, and works with deployment, packaging, and the serverless‑offline plugin.
