v0.5.0

Added

• Several internal types are now exported
• ParserError to represent errors from the err function

Changed

• BREAKING CHANGES:
  • ParserResult errors changed; now they take a generic E type to define
    their error property. No code changes are needed if your custom parsers
    only use the err function.
  • Instead of throwing on failure, schema now returns a ParserResult
    object. See README.md for details.

Removed

• BREAKING CHANGES:
  • Drop support for async validation: AsyncParser removed, SyncParser
    renamed to just Parser.
  • ValidationError removed.

v0.4.0

Changed

• Updated project to modern standards, using unbuild, vitest, modern eslint,
  etc.
• BREAKING CHANGES:
  • This package is ESM-only now and requires Node ^20.

v0.3.2

Changed

• Fix wrong return type of err

v0.3.1

Changed

• Improved typing for and; now message functions are properly typed

v0.3.0

Added

• ValidationError, thrown when a validation error occurs.
• Infer<S> takes a SchemaParser and returns the final parsed structure.
• trim is a transformer that trims both ends of a given string.
• defaultTo is a transformer that applies a default value if necessary.

Changed

• BREAKING CHANGES:
  • Vahv now uses a parsing
    methodology rather than a validation one. Thus, there are many breaking
    changes.
  • and is now always async and can always take async
    parsers.
  • Validator and AsyncValidator have been renamed to SyncParser and
    AsyncParser respectively. Parser now refers to an union of SyncParser
    and AsyncParser.
  • schema’s returned function now returns the parsed contents of the given
    data object. If there is a validation error, it throws ValidationError.
  • The internal file structure has changed.
• The messages object may not be exhaustive with regard to the given parsers
  anymore, because then you'd need to give error messages for transformers. If
  an error message is missing, an error will be thrown at runtime.
• Development dependencies have been upgraded to their latest version.

Removed

• BREAKING CHANGE: asyncAnd has been removed. Use and instead.

v0.2.0

Added

• A CHANGELOG file.
• asyncAnd, a validator that can receive sync and async validators alike.
  Always returns an async validator.

Changed

• schema now returns a Promise, resolving to a validation result.
• Validator functions can now return a Promise resolving to a validation result.
  These are async validators. Note that and can only receive sync validators;
  use asyncAnd to compose async validators.

v0.1.0

Added

• Vahv itself! This is its first release.
