Bean Scene Boilerplate Variants

This page is the fast lookup surface for backend Vona and frontend Zova bean scenes that expose more than one CLI scaffold template.

Use it when you need to answer questions such as:

• does this bean scene support --boilerplate=...
• which variant names are currently defined
• where is the source module metadata for that scene

Shared rule

Vona and Zova follow the same practical lookup rule for bean-scene boilerplate variants:

• boilerplate provides the default template
• --boilerplate=web maps to boilerplateWeb
• more generally, --boilerplate=name maps to boilerplateName

That means the available variants are scene-defined metadata, not a universal list shared by every scene.

A practical contributor rule is:

1. use the default template unless you know the scene exposes a named variant
2. check this page first for current built-in examples
3. if needed, verify the owning module package.json metadata before assuming a variant exists

Backend Vona

Current built-in scenes with variants

Scene	Default metadata key	Named variant keys	Example command	Source module
filter	boilerplate	boilerplateGlobal	npm run vona :create:bean filter log -- --module=training-student --boilerplate=global	vona-module-a-aspect
pipe	boilerplate	boilerplateGlobal	npm run vona :create:bean pipe log -- --module=training-student --boilerplate=global	vona-module-a-aspect
interceptor	boilerplate	boilerplateGlobal	npm run vona :create:bean interceptor log -- --module=training-student --boilerplate=global	vona-module-a-aspect
guard	boilerplate	boilerplateGlobal	npm run vona :create:bean guard auth -- --module=training-student --boilerplate=global	vona-module-a-aspect
middleware	boilerplate	boilerplateGlobal	npm run vona :create:bean middleware trace -- --module=training-student --boilerplate=global	vona-module-a-aspect
ssrMenu	boilerplate	boilerplateWeb	npm run vona :create:bean ssrMenu menuTest -- --module=training-student --boilerplate=web	vona-module-a-ssr
ssrMenuGroup	boilerplate	boilerplateWeb	npm run vona :create:bean ssrMenuGroup groupTest -- --module=training-student --boilerplate=web	vona-module-a-ssr

These backend entries come from the current vonaModule.onions metadata in a-aspect and a-ssr.

Frontend Zova

Current built-in scenes with variants

Scene	Default metadata key	Named variant keys	Example command pattern	Source module
command	boilerplate	boilerplateCommandBulk, boilerplateCommandRow	npm run zova :create:bean command test -- --module=training-student --boilerplate=commandRow	zova-module-a-command
tableCell	boilerplate	boilerplateTableActionRow	npm run zova :create:bean tableCell test -- --module=training-student --boilerplate=tableActionRow	zova-module-a-table

These frontend entries come from the current zovaModule.onions metadata in a-command and a-table.

Guidance for AI-assisted development

Do not assume every bean scene supports named variants.

For reliable AI-assisted workflow selection:

1. choose npm run vona for backend bean scenes and npm run zova for frontend bean scenes
2. check whether the current scene is listed on this page
3. if it is not listed, verify the owning module metadata before recommending --boilerplate=...
4. treat this page as a current built-in lookup surface, not as a promise that all future scenes will follow the same naming set
