appolodev/form-builder-bundle

Symfony bundle that lets users build custom forms (React builder), then renders them as Symfony forms, stores the answers, and displays them.

Concern	Provided by the bundle	Left to your app
Form structure	Base entities, sync use cases, FormStructureType (embeds the builder)	Concrete entities, controllers, access control
Answering	FormTypeGenerator (structure → Symfony form), AbstractFormAnswer::setAnswerData()	Routes, persistence, extra columns (company, user…)
Display	form_builder_answers() Twig function + templates	Layout, PDF styling
Files / signatures	Upload storage, cleanup listener	Download route and voter
Front	Builder (React), custom elements, Stimulus controllers	Vite/Tailwind wiring

No controllers, routes, voters or migrations are shipped.

Requirements

• PHP ≥ 8.4, Symfony 8.1, Doctrine ORM 3, symfony/uid (entity ids are Uuid)
• The default form theme and answers template are neutral (plain HTML, generic classes); the only UI dependency is symfony/ux-icons (<twig:ux:icon> for the PDF icon in answers).
• Optional: symfony/ux-autocomplete (searchable lists and free entry for Select; native lists without it).
• Front: Vite (or any bundler handling TSX), Tailwind 4, Stimulus.

Install

composer require appolodev/form-builder-bundle

Then follow docs/installation.md.

Form theme

The default theme (@FormBuilder/form_theme/default.html.twig) is neutral. For a design system, create a theme in the application and declare it via form_builder.form_theme. Blocks to override: fieldset_row, title_row, paragraph_row, repeatable_row, repeatable_child_row, add_btn, remove_btn, address_row, signature_row, file_repeatable_row, file_repeatable_child_row, form_builder_conditional_field_row (plus the *_children_prototype helper blocks). structure.html.twig is always loaded by the bundle. Keep the data-* attributes and the classes read by the Stimulus controllers (repeatable, repeatable--item, collec_child, repeatable_child, file_child, file-name, remove-container, input-delete). The former form_theme/shadcn.html.twig name remains as an alias of the default theme.

Documentation

• Installation — entities, configuration, front wiring
• Usage — admin, answering, display, files, PDF
• Reference — configuration, services, Twig, data shapes, field types
• Front end — custom elements, Stimulus controllers, builder
• skills/form-builder-integration — Claude Code skill (backend/front model + integration checklist). Install: copy the folder to .claude/skills/ of your project.

Development

composer install
composer qa        # php-cs-fixer + PHPStan (max, strict rules) + PHPUnit
pnpm install
pnpm run typecheck # tsc --noEmit on assets/builder
pnpm run test      # vitest, including the front/PHP contract check
pnpm run export-contract   # regenerate assets/builder/contract/blocks.json after changing a block

CI runs the same on PHP 8.4 and 8.5, plus the front checks. Tests are standalone unit tests; host entities are simulated by tests/Fixtures.
