sveltekit-superforms - npm Package Versions

[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.
