v1.1.1

Patch Changes

• db8eb5d: Refactor template validation to use Handlebars AST instead of regex. This internal improvement makes the code more maintainable and robust by leveraging Handlebars' built-in parser instead of complex regex patterns. No changes to the public API or behavior.

v1.1.0

Minor Changes

• 3ad2d0e: ## Performance Improvements

  • Add template compilation caching (configurable via enableCache option, defaults to true)
  • Optimize partial compilation - partials are now pre-compiled when registered for better rendering performance

  API Enhancements

  • PromptBuilder: Add new methods for richer prompt building:
    • json(data, indent?) - Format JSON data with indentation
    • link(text, url) - Create markdown links
    • image(alt, url, title?) - Create markdown images
    • checkbox(text, checked?) / checkboxes(items) - Create task lists
    • horizontalRule(char?) - Alias for separator
  • Collection transformers: Enhanced filter and reduce helpers:
    • filter now supports property-value filtering: {{filter users "status" "active"}}
    • reduce now supports operations: sum, multiply, max, min, concat

  Date Formatting Enhancements

  • Add support for additional date format patterns:
    • MMMM (full month name), MMM (abbreviated month)
    • DDDD (full day name), DDD (abbreviated day)
    • YY (2-digit year), M (single digit month), D (single digit day)

  Developer Experience

  • Enhanced error messages: Template compilation errors now include surrounding code context, line numbers, and helpful suggestions
  • Improved variable extraction: Better handling of array access, helper expressions, and complex expressions in templates
  • Standardized error handling: Created src/utils/error-handling.ts with consistent error handling utilities for transformers

  Documentation & Security

  • Fix outdated security documentation - removed deprecated options, updated examples to use current Standard Schema validation API
  • Update README.md and TRANSFORMERS.md with new features and examples

  Testing

  • Add comprehensive edge case tests covering null/undefined handling, empty collections, large templates, and error recovery scenarios

Patch Changes

• d451efb: Adds fixes to some transformers and extends test suite

v1.0.4

Patch Changes

• afc5d52: format() now automatically validates data against the schema when a schema is provided. No need for separate validation methods!

v1.0.3

Patch Changes

• f4bd4f5: refactor: Remove helpers/transformers array options and enhance README with better examples
• eea5c0b: Removes helpers

v1.0.2

Patch Changes

• 78ff0fc: Fix type inference for schema validation methods

  • formatWithSchema() now properly infers input type from schema instead of accepting unknown
  • formatWithSchemaAsync() now properly infers input type from schema
  • tryFormatWithSchema() now properly infers input type from schema
  • PromptWeaver.composeAndCreate() now preserves schema type parameter
  • PromptBuilder.toPromptWeaver() now preserves schema type parameter

  This enables full compile-time type safety when using Standard Schema validators (Zod, Valibot, ArkType, etc.)

v1.0.1

Patch Changes

• 79b9d80: Applying the patch: replacing index.mjs with index.js in the module field and the import export.

v1.0.0

Major Changes

• fea37a6: Add Standard Schema validation support

  • Implement Standard Schema (https://standardschema.dev) validation integration
  • Add schema option to PromptWeaverOptions to accept Standard Schema validators
  • Add new validation methods: validateSchema(), formatWithSchema(), createSchemaFormatter(), etc.
  • Add standalone validation utilities: validateWithSchema(), parseWithSchema(), createSafeParser(), etc.
  • Remove old data validation system (validateData(), ValidationError, strict/throwOnMissing options)
  • Works with any Standard Schema compliant library (Zod, Valibot, ArkType, Yup, Joi, etc.)

  BREAKING CHANGE: Removed ValidationError, validateData(), PromptWeaver.validate(), and strict/throwOnMissing options. Use Standard Schema validation instead.
