This file is the source of truth for what is in scope for each release. Consult it before adding any feature.
Target: 8-10 weeks from project start.
- Vue 3 adapter (
formle-vue)useForm({ schema, onSubmit })composableuseField(name)composable<Form>and<Field>components with slot-based rendering- Reactive form state (values, errors, touched, dirty, isSubmitting, isValid)
- Framework-agnostic core (
formle)- Schema parser for the custom Formle format (see
docs/SCHEMA_SPEC.md) - Validation engine, synchronous only
- Form state machine
- Submit lifecycle (idle → submitting → success | error)
- Schema parser for the custom Formle format (see
- Zod adapter —
fromZod(zodSchema)converts a Zod schema to a Formle schema - JSON Schema adapter —
fromJsonSchema(jsonSchema)converts a basic JSON Schema (Draft 2020-12) to a Formle schema. Supports common types and validation keywords; advanced features (oneOf, allOf, $ref) are deferred. - Field types:
text,email,password,number,textarea,checkbox,radio,select - Validation rules:
required,minLength,maxLength,min,max,pattern,custom(by registered ID) - Conditional rendering:
showWhenwith simple equality conditions - English error messages, default text — customizable via
messagesoption - Documentation site built with VitePress
- npm publication of both packages with
semantic-release-monorepo
These are recognized needs but explicitly out of scope for v0.1.0. Do not implement them without an explicit roadmap update.
- React adapter
- Svelte adapter
- Async validation (e.g. "check if email is available")
- Cross-field validation (e.g. "passwordConfirm === password")
- Field arrays (dynamic add/remove of repeating field groups)
- File upload field type
- Date/time picker field types
- Multi-select field type
- Built-in i18n (custom message dictionaries per locale)
- Advanced layout (tabs, accordion, multi-column)
- Multi-step / wizard forms
- AI-assisted schema generation
- JSON Schema advanced features:
oneOf,allOf,$ref,if/then/else
- Styled component library. Formle is headless. There will be no built-in CSS, no theming system. Styling is the consumer's responsibility.
- Form builder UI. Formle does not include a visual schema editor.
- Backend SDK. Formle does not ship schema-generation libraries for any backend language. Users construct schemas with their existing tools.
- Drag-and-drop reordering. Out of scope.
- Rich text editor field. Out of scope; consumers should integrate their preferred editor.
Roadmap firms up after v0.1.0 ships. Likely candidates, in priority order:
- Async validation
- Cross-field validation
- Field arrays
- React adapter
- File upload field type
Until v1.0.0, minor version bumps may include breaking changes when documented in the release notes. Patch versions are non-breaking. After v1.0.0, semantic versioning is strict.
