Changelog

1.0.0

Major Changes

• 94da43d: Breaking changes

  • Constants now use direct string values. Replace Constant.Key.value with Constant.Key everywhere (e.g. PaymentFormCode.CashPayment instead of PaymentFormCode.CashPayment.value). Human-readable descriptions and abbreviations are available from the new *Info companion exports (e.g. PaymentFormCodeInfo).
  • bills.getByNumber() renamed to bills.get().
  • FactusError constructor signature changed to an options object: new FactusError(message, { statusCode, errors?, validationErrors?, cause? }).
  • Deprecated Invoice and CreditNote types removed from types/invoice.ts and types/credit-note.ts.

  New features

  • listAll() async generator on paginated modules (bills, creditNotes, supportDocuments, adjustmentNotes, reception, numberingRanges) for transparent, automatic pagination.
  • AbortSignal support via optional options.signal parameter on every module method.
  • Automatic 401 retry with silent token refresh — the SDK retries once after refreshing credentials on a 401 response.
  • Auth token request deduplication: concurrent calls share a single in-flight token request.
  • Runtime validation of required FactusClientConfig fields (clientId, clientSecret, username, password) at construction time.
  • cause property on FactusError for wrapping low-level errors.
  • New *Info companion exports with human-readable constant descriptions and abbreviations (PaymentFormCodeInfo, IdentityDocumentTypeIdInfo, etc.).

  Type improvements

  • is_excluded tightened to 0 | 1 union.
  • dv and municipality_id standardized to string.
  • All manually duplicated { status, message, data } response interfaces replaced with ApiResponse<T> type aliases.
  • New shared types: EmailContentData, CodeNameObject, CodeNameIdObject.

  Package

  • engines: { "node": ">=18" } added to package.json.
  • sideEffects: false for better tree-shaking.
  • CI now runs on Node.js 22 LTS with npm provenance enabled on releases.

0.3.0

Minor Changes

• 2a56ba0: Stringify all DIAN catalog constant value fields (e.g. IdentityDocumentTypeId, CreditNoteOperationTypeCode, ProductStandardId, OrganizationTypeId, etc.) so runtime values and inferred TypeScript unions are string, matching the Factus PHP API’s string handling and improving compatibility with Zod, React Hook Form, and similar tooling.

  Breaking change (TypeScript): code that passed or compared numbers for these codes must use strings (e.g. "3" instead of 3, or SomeConstant.Entry.value which is now a string). RadianEventUpdateInput.identification_document_code and EmitEventInput.identification_document_code are now typed as string; invoice mandate identification_document_id fields use string as well.

  Docs and examples were updated to use .value where payloads expect scalars.

0.2.0

Minor Changes

• 3c31b65: Add abbreviation to each entry in IdentityDocumentTypeId and SupportDocumentIdentityTypeId for UI labels and display. Document the mapping in the reference tables catalog page.

0.1.3

Patch Changes

• b8d9a96: Add validation error handling to FactusError and update documentation
  • Introduced validationErrors property in FactusError to capture DIAN validation rule violations.
  • Enhanced error handling in HttpClient to populate validationErrors from API responses.
  • Updated documentation in error-handling.mdx to reflect changes and provide examples of validation error handling.
  • Added unit tests to verify the correct behavior of validation error handling in various scenarios.

0.1.2

Patch Changes

• c92791f: Refactor sandbox tests and error handling:
  • Remove deprecated error assertion helper
  • Enhance result reporting
  • Improve error message handling in HttpClient.

0.1.1

Patch Changes

• 0de24e9: Fix auth request format, race condition, type correctness, and developer experience improvements
  • Send OAuth token requests as application/x-www-form-urlencoded instead of JSON to match the Factus API documentation
  • Deduplicate concurrent authentication requests to prevent race conditions when multiple API calls trigger token refresh simultaneously
  • Fix response type wrapping for support document and adjustment note download methods to match the invoice/credit note pattern
  • Change CreditNoteOperationTypeCode constant values from strings to numbers, matching the API contract and making the constant usable with CreateCreditNoteInput.customization_id
  • Change AdjustmentNoteReasonCode constant values from numbers to strings, matching the API request format
  • Add Object.setPrototypeOf to FactusError for safe prototype chain in CJS environments
  • Replace unsafe type casts in the catalog module with a generic toQueryParams helper
  • Add payment_form field to CreateCreditNoteInput
  • Replace any[] with proper types for adjustment_notes in support document types
  • Widen RadianEventUpdateInput.identification_document_code from narrow IdentityDocumentTypeId union to number to support additional API codes
  • Add @see / {@link} references to deprecated type aliases
  • Enable sourcemaps in build output
  • Mark HttpClient class as @internal
