Service list (LC 116)

Check if a value is a subitem in force of the service list annexed to the Lei Complementar 116/2003, the list of the services the ISS is levied on.

• The law numbers a subitem as the item, a dot and two digits, 1.01 to 40.01.
• Accepts that form, a zero padded item ('01.01') or the bare digits ('0101', '101' or the integer 101), which are the first four digits of the cTribNac code of the national NFS-e, with optional surrounding whitespace.
• Any run of separators (space, ., - or /) is accepted between the item and the subitem, as in the other codes with a printed grouping mask (isValidCfop, isValidNbs), so '1-01' and '1 01' are valid too.
• A number is only read when it is a non-negative safe integer, so the float 1.01 is rejected: write the dotted form as a string.
• The vetoed subitems (3.01, 7.14, 7.15, 13.01 and 17.07), the item headings, the 6 digit national codes a subitem is split into and item 99 of the national list, which is not part of the law, are not valid. Municipal service codes are out of scope.

import { isValidServiceItem } from '@brazilian-utils/brazilian-utils';

isValidServiceItem('1.01'); // true
isValidServiceItem('01.01'); // true
isValidServiceItem('0101'); // true
isValidServiceItem(101); // true
isValidServiceItem('3.01'); // false (vetoed)
isValidServiceItem('99.01'); // false (national list only, not the law)
isValidServiceItem(1.01); // false (not a non-negative safe integer)

Look a subitem of the service list annexed to the Lei Complementar 116/2003 up and get its official description. The result is a ServiceItem record: { code, description }.

• Same rules as isValidServiceItem. code is the form the law prints ('1.01'). Returns null when the subitem is unknown or the value is not in a documented form.

import { getServiceItem } from '@brazilian-utils/brazilian-utils';

getServiceItem('1.01'); // { code: '1.01', description: 'Análise e desenvolvimento de sistemas.' }
getServiceItem('0101'); // { code: '1.01', description: 'Análise e desenvolvimento de sistemas.' }
getServiceItem('40.01'); // { code: '40.01', description: 'Obras de arte sob encomenda.' }
getServiceItem('3.01'); // null (vetoed)
