Cart.js

This is a JS library for adding a shopping cart to any frontend using Reflow Ecommerce. It is written in vanilla JS and can work in any project and framework. For React projects, you can check out the React Shopping Cart component.

Installation

npm install @reflowhq/cart

Usage

This library is meant to run in the browser. The recommended way to use it is to create an instance and assign it to the window object so that it is available globally. You can find your storeID on your Reflow admin page.

import Cart from "@reflowhq/cart";

window.cart = new Cart({ storeID: "<your storeid here>" });

API

The cart instance gives you access to a number of properties and methods for managing the current shopping cart.

cart.state

A getter which returns an object with cart information.

console.log(cart.state);

Localization

To translate this toolkit, you need to pass a localization object in the config object. This will change the entire user interface of Reflow components, including labels, text prompts and error messages. Example:

import localization from "./localization.json";

const cart = new Cart({
storeID: "1234",
localization,
});

To create a translation, follow these steps:

  1. Download the en-US.json file. This is Reflow's default language file. You will use it as a starting point.
  2. Translate some or all of the phrases to your language of choice. This is covered in the next section.
  3. Save the translation file somewhere in your project.
  4. Import it and add it to the Cart config object.
  5. Check your browser's console for any error messages that may point you to potential problems with your translation.

Translation File Format

The translation file is a simple JSON consisting of key/value pairs. The process of translating Reflow consists of rewriting the values to your language of choice.

// The default en-US.json in English
{
"locale": "en-US",

"shopping_cart": "Shopping Cart",
"product": "Product",
...
}
// A localized example in French
{
"locale": "fr-FR",

"shopping_cart": "Panier",
"product": "Produit",
...
}

Instructions

  • The keys should not be changed. They are used by the library for matching UI elements with their localized text.
  • The values represent the actual content that is visible in the UI. They should be replaced with the translation in the chosen language.
  • All lines in the JSON (except for the locale property) are optional. You can omit the lines you don't wish to translate. In that case the default English equivalent will be used.
  • The locale line is special. It only accepts a standard ISO country-language tag. This is the locale used for formatting prices and dates, among other things.

Message Format

The values in the JSON follow the standardized ICU message format. You can learn more about the message format here.

Translating Countries and Regions

In some cases the CartView component can display select inputs for customers to choose their country and region (e.g. for shipping address). By default all the countries and their regions names are shown in English.

These can be translated by adding the geo property to the localization JSON. In it, you can define what names should be displayed for the countries and regions you wish to translate. Here is an example:

"geo": {
"BE": {
"country_name": "Belgique",
},
"DE": {
"country_name": "Allemagne",
},
"CA": {
"country_name": "Canada",
"regions": {
"AB": "Alberta",
"BC": "Colombie-Britannique",
"MB": "Manitoba",
"NB": "Nouveau-Brunswick",
"NL": "Terre-Neuve-et-Labrador",
"NT": "Territoires du Nord-Ouest",
"NS": "Nouvelle-Écosse",
"NU": "Nunavut",
"ON": "Ontario",
"PE": "île du Prince-Édouard",
"QC": "Québec",
"SK": "Saskatchewan",
"YT": "Yukon"
}
},
}

We recommend downloading our example file for the geo property in English. You can then remove the countries that are unnecessary for you store, translate the ones you need and move them to your localization file under the geo property.

Local Currency

Reflow supports a wide array of currencies that can be used for everything in your store, including product prices and shipping costs. You can change the currency of your store from the general settings page.

For a full list of available currencies visit the Currency Support docs.

Test Mode

With Reflow's test mode you can try out your store integration without making actual payments. The test mode provides a separate environment that supports all of the available features from live mode, without the risk of accidentally making a payment with real money.

To enable test mode, just add testMode: true to the config object:

import Cart from "@reflowhq/cart";

window.cart = new Cart({ storeID: "<your storeid here>", testMode: true });

While testMode is active, orders will be recorded in the "Test mode" section of your Reflow store, and payments will be made with PayPal's Sandbox and Stripe's test credit card info.
