Use advanced APIs

Once the basics are in place, extend templates with the hooks below. Every API is fully typed through @timonteutelink/template-types-lib.

API	Use it for
mapFinalSettings	Derive values after validation. Ideal for generating slugs, composing booleans, or backfilling defaults.
redirects	Move rendered files to dynamic destinations (for example, namespaced feature folders).
allowedOverwrites	Explicitly permit overwriting existing files. Use sparingly—prefer targeted side effects when possible.
sideEffects	Programmatically edit files that already exist. Supply { filePath, apply } entries that return updated contents. Keep functions idempotent.
autoInstantiatedSubtemplates	Add child templates automatically based on parent settings. Supports async callbacks for lookup logic.
commands	Surface helpful commands (test, lint, launch) in the CLI and web UI after generation.
migrations	Upgrade stored settings when schemas change. Each migration has a UUID and can depend on a predecessor.
aiAutoGenerate / aiUserConversationSettings	Optional helpers for LLM-assisted scaffolding. Always provide manual fallbacks for accessibility.
