Author Q+A: finprim is a Case for One Financial Validation Library in TypeScript
finprim is an MIT-licensed TypeScript library that offers IBAN, BIC, card, sort code, VAT, routing number and loan functions through one API with no runtime dependencies. Its author built it after duplicated validators drifted apart across web and mobile. It validates and formats data only, and does not process payments. He is cautious about adding SEPA and ACH file generation. By Daniel Curtis
