Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🔵 Low · up to 82b1e

This documentation-only PR adds usage guidance, generated references, community files, and release history. Contradictory examples and support metadata could mislead users or contributors, but no runtime behavior changes or production outage or data-loss risk is identified; merge readiness is low risk with bounded follow-up.

Use one Node.js support range.

> **Input handling:** no public function throws on `null`/`undefined` or a wrong-type value. `isValid*` predicates return `false`; `isHoliday` returns `false`; `getHolidays` returns `[]`; `generateProcessoJuridico` returns `null`; `getMunicipality` returns `null` for a malformed/unmatched lookup. Every other `format*`/`parse*` function (including `capitalize`) returns an empty value of its return type: `""` for strings, `0` for `parseCurrency`. `formatCurrency` returns `""` for a non-finite number.

Correct the public error-handling contract. Line 5 says no public function throws for null/undefined or wrong-type input. The getCepInfoByAddress section states that invalid fields throw GetCepInfoByAddressValidationError. At least one statement is false, so callers cannot safely choose between exception handling and empty-result handling.

  • docs/utilities.md#L5-L5: exempt getCepInfoByAddress if it throws for invalid input, or correct its error section.
  • docs/pt-br/utilities.md#L5-L5: apply the same corrected contract in Portuguese.

Format phone number according to Brazilian patterns. `options.mask` (typed as `PhoneMask`) accepts `"sn"` (default, subscriber number only, 9 digits, no DDD), `"nanp"` (DDD + subscriber number, 11 digits), `"e164"` (`"+5511987654321"`), `"international"` (`"+55 11 98765-4321"`, the way a Brazilian number is printed for foreign callers), `"service"` (`"0800 123 4567"` or `"4004-1234"`, the conventional groupings for service numbers) or `"auto"`. `"auto"` picks `"international"` when `value` carries a Brazilian country code (`+55`, `0055` or a bare `55` followed by 10 or 11 digits), `"service"` when `value` is a service number, and otherwise falls back to the digit count: `"nanp"` when `value` has more digits than a bare subscriber number, `"sn"` when it does not. `"e164"` and `"international"` drop the country code from `value` first, under the rule documented in `parsePhone`, and fall back to the `"service"` presentation for a service number, since those have no E.164 form. If `value` includes a DDD, pass `{ mask: 'auto' }` (or `'nanp'`) explicitly, since the default `"sn"` mask assumes no DDD and silently truncates one if present.

```javascript
import { formatPhone } from '@brazilian-utils/brazilian-utils';

formatPhone('11900000000'); // 90000-0000
formatPhone('987654321'); // 98765-4321 (default "sn", no DDD)
formatPhone('11900000000', { mask: 'nanp' }); // (11) 90000-0000
formatPhone('11900000000', { mask: 'auto' }); // Automatically detects mask based on length
formatPhone('11900000000', { mask: 'auto' }); // (11) 90000-0000
formatPhone('11987654321', { mask: 'e164' }); // +5511987654321
formatPhone('+5511987654321', { mask: 'international' }); // +55 11 98765-4321
formatPhone('08001234567', { mask: 'service' }); // 0800 123 4567
formatPhone('40041234', { mask: 'service' }); // 4004-1234
formatPhone('+5511987654321', { mask: 'auto' }); // (55) 11987-6543 (BEWARE: "auto" does not detect the +55 prefix)

Reconcile the formatPhone "auto" contract and example. Line 330 says "auto" detects a Brazilian country code and selects "international". Line 342 says the same +55 input is not detected and shows a different result. One of these outcomes is incorrect.

  • docs/utilities.md#L330-L342: make the behavior description and +5511987654321 example match the implementation.
  • docs/pt-br/utilities.md#L330-L342: make the Portuguese description and example match the same behavior.

Transforms the first letter into a capital one of each word ignoring prepositions. Words are separated by whitespace, by `-` and by `/`, so `'MOGI-GUAÇU'` becomes `'Mogi-Guaçu'` and `'SANTANA/RS'` becomes `'Santana/Rs'`. Every run of whitespace (tabs, newlines, repeated spaces) collapses into a single space, and the leading and trailing whitespace is dropped. `options.upperCaseWords` defaults to `[]`, so no acronym is upper-cased unless you list it, and the comparison against both `upperCaseWords` and `lowerCaseWords` is case-insensitive (pt-BR locale). Options are typed as `CapitalizeOptions`.

```javascript
import { capitalize } from '@brazilian-utils/brazilian-utils';

capitalize('josé e maria'); // José e Maria
capitalize('josé Ama MARIA', { lowerCaseWords: ['ama'] }); // José ama Maria
capitalize('doc inválido', { upperCaseWords: ['DOC'] }); // DOC Inválido
capitalize('MOGI-GUAÇU'); // Mogi-guaçu ("-" does not start a new word)
capitalize('SANTANA/RS', { upperCaseWords: ['RS'] }); // Santana/rs ("SANTANA/RS" is a single word, so it doesn't match "RS")
capitalize('empresa ltda'); // Empresa Ltda (no default acronyms)
capitalize('empresa ltda', { upperCaseWords: ['LTDA'] }); // Empresa LTDA (case-insensitive match)
capitalize(' josé maria '); // José Maria (repeated plain spaces collapse; tabs/newlines would not)

Reconcile the capitalize delimiter and whitespace rules. Line 771 says -, /, tabs, and newlines split or collapse words. Lines 779-783 say those same inputs do not have that behavior. Users cannot determine the supported normalization rules.

  • docs/utilities.md#L771-L783: align the prose and examples with the implementation.
  • docs/pt-br/utilities.md#L771-L783: apply the same correction in Portuguese.

Formats an integer or float to a string in the BRL pattern. A `number` is formatted as-is (sign and decimals preserved). A `string` input is read by the same rule as `parseCurrency`, except that a value written without any separator stays in whole units: the last `,` or `.` followed by 1 to 2 digits is the decimal separator, every other `,` or `.` is a thousands separator, and a `-` written before the first digit is preserved. So `'1.234,56'` formats as `1.234,56`, `'-10.5'` as `-10,50` and `'1234'` as `1.234,00`. `precision` is clamped to `0..20` (the range `Intl.NumberFormat` accepts) and defaults to 2. A value that is not a finite number (`NaN`, `Infinity`, `-Infinity`) formats as an empty string. Options are typed as `FormatCurrencyOptions`.

```javascript
import { formatCurrency } from '@brazilian-utils/brazilian-utils';

formatCurrency(10); // 10,00
formatCurrency(10756.11); // 10.756,11
formatCurrency(10756.123, { precision: 3 }); // 10.756,123
formatCurrency(1234.56, { symbol: true }); // R$ 1.234,56
formatCurrency(-1050); // -1.050,00 (a number's sign is preserved)
formatCurrency('123456'); // 123.456,00 (a plain digit string is read as a whole number)
formatCurrency('1.234,56'); // 123.456,00 (a string's separators are stripped, not interpreted)
formatCurrency('-10.5'); // 105,00 (a string's sign is discarded)
formatCurrency(Number.NaN); // "NaN"

Correct the contradictory currency examples. The prose says formatCurrency('1.234,56') preserves separators and formatCurrency(Number.NaN) returns "". Lines 799 and 801 show 123.456,00 and "NaN". The parseCurrency prose also conflicts with Lines 814-815. These examples can cause incorrect monetary conversions.

  • docs/utilities.md#L806-L818: make parseCurrency examples match its decimal-separator rules.
