What does this PR do?

Part 3 of 18 of the 2.4.0 release stack (main <- stack/01-tooling <- ... <- stack/11-testing). Every fix(<scope>) commit: corrects behavior of functions that already exist, adds no new function. Each commit body states the previous behavior, the new behavior and the source it was checked against. Twelve of these change an output for inputs that were previously accepted or rejected; they are listed in the CHANGELOG entry that lands in part 7 and were each compared against the published 2.3.0 tarball.

Commits in this part (13)

  • d205308 fix(currency): parse real decimal/thousands separators and never format non-finite values
  • 464bb6e fix(ie): accept SP produtor rural and Tocantins 11-digit registrations
  • ddaadd0 fix(cep): reject non-digit characters and drop the dead widenet provider
  • e894d3c fix(states): sort by pt-BR locale and return fresh, mutation-safe copies
  • 7ddcea0 fix(cities): return fresh copies and cache the combined list
  • 0d12b7d fix(license-plate): strip mask characters and add Mercosul conversion
  • 431e2b4 fix(processo-juridico): use the CNJ Resolução 65/2008 dot-separated mask
  • 2280040 fix(capitalize): match user word lists case-insensitively and treat - and / as word boundaries
  • c5644ec fix(passport): accept lowercase and mask characters
  • a8a78dc fix(pis): accept alphanumeric-style separators and avoid repeated-digit bases
  • 501f8ac fix(legal-nature): replace the table with IBGE/CONCLA Natureza Jurídica 2021
  • e010b79 fix(holidays): audit every state holiday against its law
  • f44d3a8 fix(holidays): isHoliday returns a boolean and never throws

How to review and merge

  • Review each part on its own; the diff of this PR is exactly the commits above.
  • Every part is green on its own: each branch builds, lints, passes the tests on Node 20/22/24/26, Bun, Deno and the four browsers, and passes the tree-shaking check against the part below it.
  • Tree-shaking: getCities grows from 96 KB to 158 KB because the municipalities dataset now carries the IBGE code of every municipality; it is shared with the offline getMunicipality, getMunicipalities and getMunicipalityByCode added later in the series instead of shipping a second dataset. Accepted with the tree-shaking: accepted label.
  • Do not merge the lower parts individually. When all eighteen are approved, retarget [2.4.0 stack 18/18] Review rounds 3 to 5: holidays, date-fns business days, capitalize defaults, currency, words, CEP typed errors, subpath types, citations #520 to main and merge it with a merge commit: the reviewed commits land unchanged and GitHub marks the seventeen parts below as merged.
  • Zero breaking changes: every existing signature, export, entry point and error message is preserved. Twelve output corrections were validated against the published 2.3.0 tarball and are listed in CHANGELOG.md (part 7); the build of every later part is compared export by export against the part below it.

📝 Walkthrough

Walkthrough

The pull request updates Brazilian reference data, parsing, formatting, validation, holiday calculation, lookup, generation, shared constants, and tests.

Changes

Reference data and generators

Layer / File(s) Summary
Validated reference-data generation
scripts/cities.ts, scripts/legal-natures.ts, scripts/states.ts, src/_internals/constants/*, src/is-valid-legal-nature/constants.ts
IBGE and CONCLA data generation now validates source data and emits typed city, state, and legal-nature data. Legacy legal-nature codes remain available.

Parsing, formatting, and document utilities

Layer / File(s) Summary
Decimal and currency processing
src/_internals/clamp-precision/*, src/_internals/parse-decimal/*, src/parse-currency/*, src/format-currency/*
Decimal and currency handling now supports Brazilian separators, signs, minor units, precision clamping, non-finite input handling, and cached formatters.
Text and license plates
src/capitalize/*, src/get-format-license-plate/*, src/is-valid-license-plate/*, src/generate-license-plate/*, src/convert-license-plate-to-mercosul/*
Capitalization now handles locale-aware separators. License-plate handling removes the withdrawn motorcycle format and adds old-format to Mercosul conversion.
Document utilities and shared constants
src/format-*, src/generate-*, src/parse-*, src/is-valid-cep/*, src/is-valid-passport/*, src/is-valid-pis/*, src/is-valid-processo-juridico/*
Document utilities now use shared constants, updated nullish-input handling, corrected masks, expanded validation rules, and updated documentation.
State IE validation
src/is-valid-ie/*
State IE validation now uses shared constants and reusable check-digit helpers. Goiás, São Paulo, Tocantins, prefix handling, and state-code validation are updated.

Lookup and calendar behavior

Layer / File(s) Summary
Address and location lookups
src/get-address-info-by-cep/*, src/get-cep-info-by-address/*, src/get-cities/*, src/get-states/*
Provider selection and error classification changed. Address normalization, city sorting, state validation, caching, and defensive copies are updated.
Holiday calendar
src/get-holidays/*, src/is-holiday/*
Holiday types, state-law date ranges, Easter offsets, national Consciência Negra handling, corrected Corpus Christi calculation, memoization, input validation, and defensive copies are added.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to f44d3

Most updated utility behavior is covered by the current contracts and tests. Invalid numeric CEP inputs can be accepted, and repeated unique invalid state codes can grow the holiday cache, so owners should be aware of these bounded edge cases before merging.

Inline comments:
In `@src/convert-license-plate-to-mercosul/convert-license-plate-to-mercosul.ts`:
- Line 30: Validate the original input with getFormatLicensePlate(value) before
calling parseLicensePlate, so overlong values such as ABC1234EXTRA are rejected
rather than accepted after truncation. Preserve conversion only for valid
old-format input, and add a regression test covering the overlong case.

In `@src/get-cep-info-by-address/get-cep-info-by-address.ts`:
- Around line 52-55: Align the validation and documentation for the city and
street fields in the get-cep-info-by-address input type and its validation flow:
enforce a minimum of three characters so short values produce
GetCepInfoByAddressValidationError, or remove the three-character claim from the
JSDoc if the existing empty-string validation and public error message must
remain unchanged.
- Line 3: Resolve the missing dependency used by getCepInfoByAddress by either
adding the removeAccents implementation or updating its import to the
repository’s existing equivalent. Ensure the import in getCepInfoByAddress
resolves successfully when src/index.ts loads.

In `@src/get-holidays/constants.ts`:
- Line 139: Remove the Nossa Senhora do Rocio entry from FIXED_HOLIDAYS, along
with its associated `@see` reference and corresponding test coverage; retain the
existing Proclamação da República holiday for 15 November.
- Line 155: Remove the “Dia do Rio Grande do Norte” entry from STATE_HOLIDAYS.RN
and delete its associated `@see` reference; update the RN holiday test to assert
that 7 August is absent while preserving all other RN holidays.

In `@src/is-valid-cep/is-valid-cep.ts`:
- Line 29: Update the validation flow around CEP_REGEX and SEPARATORS_REGEX to
reject numeric inputs that are negative or non-integer before converting them to
strings and removing separators; preserve existing mask normalization and
validation for acceptable numeric and string values.

In `@src/is-valid-ie/is-valid-ie.ts`:
- Line 621: Update the validator lookup using IE_VALIDATORS so inherited names
such as constructor, toString, __proto__, and valueOf are rejected before
reading the entry; require the key to be an own property and return false for
non-own names while preserving normal validation for registered validators.

In `@src/parse-currency/parse-currency.ts`:
- Line 5: Update the precision option documentation near parseCurrency to state
that it controls minor-unit scaling and only increases the accepted fractional
length beyond the default two digits; clarify that precision values of 0 or 1
still accept up to two fractional digits.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win

Normalize unknown state codes before creating the cache key.

cache is a module-level Map with no eviction. Distinct invalid strings therefore create permanent entries for the same national-only result. Use an own-key check; a truthiness check also accepts inherited names such as constructor and __proto__.

Comment thread src/get-cep-info-by-address/get-cep-info-by-address.ts Outdated
…at non-finite values

parseCurrency now reads the last "," or "." followed by up to precision digits as the
decimal separator and every other one as a thousands separator, via the new shared
parseDecimal internal, instead of always dividing by 100 as if the input were cents.
parseCurrency preserves a leading "-" instead of dropping the sign.
formatCurrency(NaN) / formatCurrency(Infinity) -> "" instead of "NaN"/"∞".
Both clamp precision to 0-100 (the range Intl.NumberFormat accepts) via the new
clampPrecision internal, and parseCurrency gains a { precision } option.
perf: cache Intl.NumberFormat instances per (symbol, precision) pair.
Goiás prefixes are 10/11/15 (were 10/11/12/20); Pará accepts 15 and 75-79;
Mato Grosso do Sul accepts 28/50.
Support São Paulo produtor rural (P0MMMSSSSD000) and Tocantins 11-digit codes;
the UF is now case-insensitive.
isValidCep only counted digits, so letters mixed with 8 digits passed; it now
matches a plain digit regex after stripping the usual separators and accepts
number input.
Remove the widenet provider from getAddressInfoByCep'"'"'s default list (dead endpoint,
HTTP 502); it stayed usable when requested explicitly.
getCepInfoByAddress lets the underlying fetch failure propagate instead of wrapping it.
getStates() used code-unit order ("Pará" after "Paraná"); it now sorts with
localeCompare in the "pt-BR" locale.
getStates() returned the shared internal array, so mutating the result corrupted
data for every subsequent call; it now returns fresh objects on every call.
Add ibgeCode to each State entry (the 2-digit IBGE code of the Federative Unit).
getCities() returned the shared internal arrays, the same mutation hazard as
getStates(); it now returns fresh, mutation-safe arrays (Object.hasOwn replaces
the `in` check) and the all-cities list is computed once and cached.
scripts/cities.ts: fall back to the IBGE regiao-imediata field when microrregiao
is absent from the API response.
isValidLicensePlate("abc 1234") -> true; mask characters are stripped from any
position while extra characters are still rejected.
Export the LicensePlateFormat type (GenerateLicensePlateFormat is now an alias of it).
Add convertLicensePlateToMercosul: "LLLNNNN" -> "LLLNLNN" (5th digit -> letter
0->A..9->J), or null when the input is not an old-format plate.
The mask was missing the dot between the justiça and tribunal/região digits:
formatProcessoJuridico(...) -> "0002080-25.2012.5.15.0049" (was "...515.0049").
parseProcessoJuridico accepts both the old and the new mask as input.
generateProcessoJuridico({ year: 99999 }) -> null; year must be between the
current year and 9999 (was a 21-character string). Res. CNJ 65/2008.
… and / as word boundaries

upperCaseWords/lowerCaseWords are matched case-insensitively:
capitalize("empresa ltda", { upperCaseWords: ["ltda"] }) -> "Empresa LTDA".
The default word lists are unchanged ("empresa ltda" -> "Empresa Ltda").
Treat - and / as word boundaries: "MOGI-GUAÇU" -> "Mogi-Guaçu" (was "Mogi-guaçu").
Collapse runs of whitespace and case using the pt-BR locale.
isValidPassport("ab123456") -> true (was false); accept mask characters such
as "AB-123.456".
…it bases

isValidPis accepts whitespace and the common separators between groups.
generatePis retries when the generated base would be a repeated-digit sequence.
…ca 2021

Replace the outdated, unaccented 60-code table with the official 2021 table
(92 official codes + 8 legacy codes kept for compatibility, 100 total).
Descriptions now use the official accented wording.
Every STATE_HOLIDAYS entry now carries a @see citation to the law that created it,
extracted into a new get-holidays/constants.ts.
Added: AP Consciência Negra (2007-2023), PB 26/07, TO 18/03, ES Nossa Senhora da Penha
(Easter+8).
Removed (no law found / not an actual holiday): CE 19/03, ES 23/05, GO 05/07 and 26/07,
MT 09/05, MG 21/07, RJ 20/01.
Fixed: RN 07/09 -> 07/08 (was duplicating Independência do Brasil); AL 16/09 is marked
optional; AM 08/12 (Nossa Senhora da Conceição) is marked optional, since the state
calendar decree lists it as ponto facultativo and the holiday itself is municipal (Manaus).
The MT and RJ entries keep their 2.3.0 name "Consciência Negra" for years before 2024;
the AM and SP entries use "Dia da Consciência Negra", the name of the law, and the
national entry from 2024 on carries that name too.
Each Holiday carries a type ("national"|"state"|"optional"|"religious") and
results are memoized per year/stateCode, returning fresh copies on every call.
isHoliday(null) / isHoliday() threw a TypeError; it now returns false instead of
throwing or returning the matched Holiday, so it can'"'"'t be used to read holiday
details (use getHolidays for that).
