[Unreleased]

Added

• errorMap option for the Zod adapter, for simplified error handling in localization. (Zod docs)

Fixed

• isTainted now works with undefined values in the $tainted store.
• Fixed default properties for Record in schemas.

[2.13.1] - 2024-05-07

Fixed

• FormPath now extends only basic objects and arrays, avoiding issues with classes, all built-in objects like File and Date, and special "branded" types that validation libraries are using. Thanks to Matt DeKok for this fix!
• SuperDebug always renders left-to-right now.
• Discriminated unions for the form itself weren't including the union keys for the schema, when parsing the form data.
• devalue updated to ^5.0.0 to handle invalid dates.

[2.13.0] - 2024-05-03

Added

• Support for "raw" JSON Schema validation with the new schemasafe adapter. Thanks to sukeshpabolu for the initial work on this!

Fixed

• Errors weren't reset properly when the form was resetted, causing client-side validation to behave like the field was tainted.

[2.12.6] - 2024-04-23

Fixed

• The Zod adapter didn't handle reused schemas ($ref) properly.

[2.12.5] - 2024-04-16

Fixed

• The "GET to POST" modification for use:enhance was only intended for SPA mode to fully support progressive enhancement, so it now properly checks for that before adding the missing method="POST" attribute on the form.
• The tainted message didn't trigger on page refresh or closing a tab in the browser.

[2.12.4] - 2024-04-09

Fixed

• FormPathLeaves caused a memory leak when using svelte-package.

[2.12.3] - 2024-04-08

Fixed

• SuperDebug support for Map and Set.
• submit method now falls back to submit, if no support for requestSubmit in browser.
• isTainted now handles the type of $tainted in generic components.
• id option for superForm (not superValidate) wasn't used in multiple form scenarios.

[2.12.2] - 2024-03-29

Fixed

• Fixed FormResult type that can be used in onUpdate, it didn't filter out SuperValidated.

[2.12.0] - 2024-03-28

Added

• SPA action form now supports form elements as well, by adding its use:enhance on all related forms.

Fixed

• Fixed type inference for FormPath with nested arrays. Error output improved as well.
• If method is "GET" or doesn't exist on an enhanced form, it's now automatically set to "POST".

[2.11.0] - 2024-03-22

Added

• The ActionResult for success or failure is now added to the onUpdate event in the result property. Can be used to more easily access the ActionData.
• Added a fail function, works the same as the SvelteKit fail, but removes files and sets form.valid to false.
• options.config added to the Zod adapter, so the JSON Schema generation can be customized.

Fixed

• Snapshots couldn't handle files. They are now reverted to their default value when captured and restored in a snapshot, including the tainted state for these fields.

[2.10.6] - 2024-03-20

Changed

• The clearOnSubmit option didn't clear the errors when supposed to. To avoid a breaking change, the default option for clearOnSubmit is now message, not errors-and-message, as it didn't work anyway.

Fixed

• the event.result.error signature in onError was incorrect, it doesn't always match App.Error. It is now a union between App.Error, The built-in JS Error class, and the default App.Error signature { message: string }.

[2.10.5] - 2024-03-18

Added

• fileProxy, filesProxy, fileFieldProxy and filesFieldProxy, so File objects can be used with bind:files on the input field. See file uploads for examples.
• Exported FormPathLeavesWithErrors, for the setError function.

Fixed

• Support for instance and special validators for Valibot, which now enables File validation for Valibot!
• taintedMessage didn't always work when navigating with the History API.
• tainted didn't untaint automatically when using arrays.
• Client-side validation triggered for incorrect fields when starting with the same name.

[2.9.0] - 2024-03-12

Added

• "SPA action mode", the SPA option can now take a string, corresponding to a form action, and it will post there, even without a html form on the page. Especially useful for debounced server checks like available usernames.

Fixed

• Fixed types for constraints, tainted and errors when using intersections and unions in schemas.
• Fixed SuperDebug collapsed height by preventing global css leak.
• Redirect in SPA mode cancelled normal redirects, preventing applyAction.
• Default objects sent to superForm returned a form with an empty id, causing collisions, it is now a random string.
• customValidity didn't clear without client-side validators.

[2.8.1] - 2024-03-07

Added

• Clipboard copy button for SuperDebug. Also fixed height when collapsed without label.

Fixed

• Storybook fix for missing page store.

[2.8.0] - 2024-03-05

Added

• Support for object unions, with implicit default values.
• Experimental storybook support.

Fixed

• It wasn't possible to directly assign undefined to a field in the $errors store.
• Intersections in Zod schemas weren't handled properly.
• It wasn't possible to change the reference to the result in onResult.

[2.7.0] - 2024-03-03

Added

• newState option for reset, to set a new state for future resets. Can be used instead of the data option.

Fixed

• Empty file entries didn't return null for nullable schema fields. Ensure that all required file fields aren't set to nullable.
• Allowed string index in $errors and $tainted.
• submit can now be passed directly to event handlers.
• Updated to latest valibot-json-schema, with support for enum_, amongst others.
• Zod adapter now supports ZodType.

[2.6.2] - 2024-02-25

Fixed

• Schema literals weren't treated as their typeof type, which prevented multi-type union detection.
• FormPath and FormPathLeaves didn't narrow the types correctly for Date, Set and File.
• stringProxy didn't accept FormPathLeaves as path.
• Fixed removal of uploads for empty files (as is the default for empty file inputs), they are now ignored.
• Exported Schema type, for any supported validation schema.

[2.6.1] - 2024-02-24

Added

• Type narrowing for FormPath and its relatives, to filter the paths based on a specific type, like FormPathLeaves<T, Date>.
• Proxy types: FieldProxy, FormFieldProxy and ArrayProxy.
• Added invalidateAll option 'force', to always use the load function form data, instead of the one returned from the form action. Useful when updating the form data partially, to ensure that the data is refreshed from the server (a "pessimistic" update compared to the default, which is optimistic). Setting this also bases the reset function on the latest load function data returned for the form.

Fixed

• defaults didn't infer the input type, and didn't generate correct SuperValidated data, making superForm confused. Also fixed type signature and removed the jsonSchema option that wasn't applicable.
• Using goto in events didn't work when the target page redirected.
• FormPath and FormPathLeaves didn't handle fields with type unknown and any.
• Missing boolean fields were valid in strict mode.

[2.5.0] - 2024-02-21

Added

• get and set accessor for onChange.
• submit method for superForm, a convenience instead of using requestSubmit. Requires use:enhance or that a HTMLElement inside the form (or the form itself) is passed as an argument.

Fixed

• Type parameter was missing in ChangeEvent, which should be of the inferred schema type.
• Type for onChange.paths wasn't strongly typed to FormPath.
• Initial data was dereferenced after calling superForm, so it wasn't possible to update it when using reset.
• FormOptions type required a type parameter that should've been defaulted to Record<string, unknown>.
• Auto-overflow on SuperDebug, for small spaces.

[2.4.0] - 2024-02-20

Added

• Added config option to Valibot adapter, for the SchemaConfig type.

Fixed

• Nullable fields weren't always detected in JSON Schemas.
• Constraints weren't added when using default values for Arktype, Vine and Valibot schemas.
• Fixed null support for Joi, Arktype and Vine schemas.

[2.3.0] - 2024-02-18

Fixed

• Depending on the JSON Schema, dates were sometimes set to undefined when posting invalid data.

Added

• onSubmit.jsonData, to override what's being submitted, when dataType is set to 'json' and validation succeeds for $form.
• onSubmit.validators, to temporarily override validators for the current submission.

[2.2.1] - 2024-02-16

Fixed

• Added focusOnError option to SuperForm.validateForm type (it was only in the implementation).
• Enums could not be detected as an invalid value if the posted value was an empty string, instead it defaulted to the enum first value.
• $posted was reset by mistake to false after posting, when resetForm option was true.

[2.2.0] - 2024-02-15

Added

• VineJS adapter!
• Added focusOnError option to validateForm, default true.

Fixed

• Autofocus is now working when using validateForm({ update: true }).
• Default values are now applied properly for single-type unions, even a mix of integers and numbers.
• SuperStruct types, $errors primarily, didn't handle nested data properly.

Changed

• The inferred type parameters were swapped in message, it can now be used to specify the message type.

[2.1.0] - 2024-02-12

Fixed

• Enums can now be required again, as they don't need an explicit default value anymore. If no explicit default value exists, the first enum value will be used.
• Empty arrays were set to undefined when using dataType: 'json'.

[2.0.0] - 2024-02-11

Removed

• superForm.fields was a rarely used and lesser version of formFieldProxy, switch to that instead.
• Removed fields options when setting tainted status.
• Remvoed message parameter in onError event, use $message directly instead.

Changed

• Adapters required for validation! Import from sveltekit-superforms/adapters and use superValidate(zod(schema)) instead of superValidate(schema). If type parameters are used, it must now be wrapped with Infer for schemas.
• Default superForm options now follow SvelteKit more closely: resetForm: true and taintedMessage: false are default now. Add define: { SUPERFORMS_LEGACY: true } in vite.config.ts to keep the old behavior.
• superValidateSync is renamed to defaults. It returns default values for the schema, and does no validation anymore. Use +page.ts if initial validation is required, as described on the SPA page.
• arrayProxy: fieldErrors renamed to valueErrors.
• Enums must have an explicit default value in the schema.
• Numeric enums cannot be parsed with their string values anymore.
• Superform validator functions, previously just an object with functions, requires the superformClient adapter. The input for the validator functions can now be undefined.
• If superValidate is called with just the schema, the default values aren't validated (i.e. no side-effects for default values) unless errors is set to true.
• Properties with default values don't have required in their constraints anymore.
• Form id cannot be undefined anymore, must be string. (Set automatically by default now).
• flashMessage.onError.message option in superForm renamed to flashMessage.onError.flashMessage.
• constraints are now optional in the SuperValidated type, and are returned only when loading data, not posting. This is only relevant if you modify constraints before calling superForm.
• Removed the defaultValidators option, 'clear' can now be set directly on validators instead.
• Removed the emptyIfZero setting from numberProxy and intProxy.
• validate() called with no arguments is renamed to validateForm() and can take two extra options, update and schema.

Added

• Support for unions in schemas. A union must have an explicit default value, and multi-type unions can only be used with dataType: 'json' set.
• Added superForm.isTainted(path?) and superForm.isTainted($tainted) for better tainted fields check.
• File upload support! Use withFiles when returning in form actions: return withFiles({ form }).
• SuperDebug now displays File and FileList.
• All proxies can now take the whole superForm object (previously only the form store was accepted), with an extra taint option to prevent tainting.
• taintedMessage can now be an async function resolving to true if navigation should be allowed, despite the form being tainted.
• Added an onChange event to superForm, that returns a list of modified fields whenever $form is updated.
• Added 'zero' to the empty option of numberProxy and intProxy. Also added initiallyEmptyIfZero option, to show the placeholder for numeric inputs, which would otherwise display 0.
