@miaou/types v2.2.0

@miaou/types Typing Brand utility

Usable type only to avoid copy/pasting everytime we start a new project. This lib use ts-brand, more information about branding in the repo.

import { Minute } from './date'

const addMinutes = (minutes: Minute) =>  minutes // type = (Minute) => Minute
const minutes = 10 as Minute // Branding

// Syntax Error: 10 is not compatible with Minute type  
addMinutes(10)

// Compile
addMinutes(minutes) 
addMinutes(10 as Minute)

// Compile but total is a type of number and not Minute
const total = minutes + 30

Install

yarn add --exact --dev @miaou/types

Money

Amount

AmountUsd AmountEur

When working with money, to avoid convert everytime, we use a reference currency (EUR or USD) to work with.

Pro:

• It's simplify a lot the development
• Avoid to convert with current rate at every time we want to compute amounts
• The converting is only made by the front or at the border of the domain

Con:

• This approach are not working for all situation
• We don't have enough vision to validate this solution yet
