Dinero.js is a JavaScript and TypeScript library for creating, calculating, converting, comparing, and formatting monetary values safely. It uses immutable objects and integer minor units to avoid floating-point precision issues, with built-in ISO 4217 currency support.

Use cases

• handle money in javascript without floating point errors
• add and subtract currency amounts safely
• format prices for display in a web app
• convert between currencies in typescript
• store monetary values as integers in minor units
• compare monetary amounts in an e-commerce checkout
• support non-decimal currencies with multiple subdivisions

When to choose

• you need precise, immutable monetary arithmetic in JavaScript or TypeScript
• you want tree-shakeable, framework-agnostic money handling with strong type safety
• you need to support many ISO 4217 currencies including non-decimal ones

When to avoid

• you need a full accounting or invoicing system rather than a value library
• your project is not JavaScript/TypeScript based
• you need built-in exchange-rate fetching or payment processing
