Steps to get started with Expo, Typescript, ESLint and Prettier

The first step is to use the Expo CLI to initialize the project. If you don't have the latest version of the Expo CLI tool, (or you don't have it installed) run npm install -g expo-cli.

Now run the following commands in the same order:

• expo init my-app -t expo-template-blank-typescript
• npx install-peerdeps --dev eslint-config-airbnb
• npm i --save-dev @typescript-eslint/parser @typescript-eslint/eslint-plugin
• npm i --save-dev prettier eslint-config-prettier eslint-plugin-prettier

Create or edit the file .eslintrc.json with the following content:

mrcrowl

// path: store/basket/basket.ts (module)

import { RootState } from "../../store"
import inventory, { Product } from "../inventory/inventory"

export interface Item { productId: string, quantity: number }
export interface DisplayItem { product: Product, quantity: number }
export interface BasketState { items: Item[], isLoading: boolean }

const initialBasketState: BasketState = { items: [], isLoading: false }

// === Arrays

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2


// Use from functions, only select from pattern
var foo = () => [1, 2, 3];
