What is the proper way to tap into the features provided by DefinitelyTyped in typescript?

While working on my Angular2 app that deals with money amounts, I decided to use dinero.js to handle money values. However, I am encountering difficulties in accessing certain features in Typescript.

Following the instructions, I installed the DefinitelyTyped mappings for dinero.js using this command:

npm install @types/dinero.js --save

You can find the type mappings for this library here.

To import the library into my code, I used the following syntax:

import * as Dinero from 'dinero.js';

This allows me to utilize the factory function Dinero. The issue arises when trying to access functions like maximum and minimum, which are mentioned in the declaration but proving difficult to reach.

When attempting to call Dinero.maximum(...), I receive the error message:

"export 'maximum' (imported as 'Dinero') was not found in 'dinero.js'

Similarly, directly importing these functions and calling them like so:

import {maximum, minimum} from 'dinero.js';

Results in the error:

"export 'minimum' was not found in 'dinero.js'

I am seeking guidance on how to successfully access these functions within my code.

Answer №1

To get started, start by installing the following packages:

npm install dinero.js --save

npm install @types/dinero.js --save

Once installed, you can import and use it in your code like so:

import  Dinero from "dinero.js";

const some_currency: Dinery.Currency = 'USD'
const some_val: Dinero.Dinero = Dinero({amount: 0, currency: some_currency})
