| 3 | +--- |
| 4 | + |
| 5 | +# Configuration |
| 6 | + |
| 7 | +The Cart package is configured using a JavaScript, CSS, and data attributes-based API. |
| 8 | + |
| 9 | +## Initialization |
| 10 | + |
| 11 | +Before adding items to a cart, it is required that the Cart package is initialized with some default settings. This is done using the `UCC.init` global function which should be executed after the `umbraco-commerce-cart.js` file is loaded. |
| 12 | + |
| 13 | +```javascript |
| 14 | +<script src="/App_Plugins/UmbracoCommerceCart/umbraco-commerce-cart.js" defer></script> |
| 15 | +<script> |
| 16 | + window.addEventListener('DOMContentLoaded', function() { |
| 17 | + UCC.init({ |
| 18 | + store: 'blendid', |
| 19 | + checkoutUrl: '/checkout', |
| 20 | + showPricesIncludingTax: true |
| 21 | + }); |
| 22 | + }); |
| 23 | +</script> |
| 24 | +``` |
| 25 | + |
| 26 | +The core initialization settings are shown in the table below. |
| 27 | + |
| 28 | +| Key | Description | |
| 29 | +| -- | -- | |
| 30 | +| `store` | The ID or alias of the store the cart should be associated with. | |
| 31 | +| `checkoutUrl` | The URL of the checkout page the cart should redirect to on checkout. | |
| 32 | +| `showPricesIncludingTax` | Define whether to show prices inclusive or exclusive of sales tax. Defaults to `false`. | |
| 33 | + |
| 34 | +Calling the `init` method will also automatically bind any UI elements configured using the following APIs. |
| 35 | + |
| 36 | +## UI Elements |
| 37 | + |
| 38 | +### Add to Cart Buttons |
| 39 | + |
| 40 | +With Umbraco Commerce Cart, products that can be added to a cart are defined by adding attributes to HTML elements on your site. Most likely this will be a "buy" `<button>` element, however, any HTML element can become an add-to-cart component. |
| 41 | + |
| 42 | +The first step when defining an add-to-cart component is to add the `ucc-add-to-cart` class to the element. This informs Umbraco Commerce Cart that it should react to that element's click event. |
| 43 | + |
| 44 | +```html |
| 45 | +<button class="ucc-add-to-cart" |
| 46 | + data-ucc-product-reference="828c0bfe-c0e7-4891-a36b-187b658357fc"> |
| 47 | + Add to cart |
| 48 | +</button> |
| 49 | +``` |
| 50 | + |
| 51 | +Along with the `ucc-add-to-cart` class, a series of data attributes provides information about the product being added to the cart. At a minimum, a `data-ucc-product-reference` is required, but the following table outlines all the available configuration options. |
| 52 | + |
| 53 | +| Key | Description | |
| 54 | +| -- | -- | |
| 55 | +| `data-ucc-product-reference` | The unique reference for the product being added. This is usually the Key of the product Umbraco node. | |
| 56 | +| `data-ucc-product-variant-reference` | The unique reference for a variant of the primary product being added. This is usually either a child variant node Key or the Key of a complex variant item from the Variants property editor. |
| 57 | +| `data-ucc-quantity` | The amount of the given product to be added. | |
| 58 | +| `data-ucc-property1-key` | The key of a property to set on the added order line. | |
| 59 | +| `data-ucc-property1-value` | The value of a property to set on the added order line. | |
| 60 | +| `data-ucc-bundle-reference` | A unique reference to use to mark this item as a bundle. | |
| 61 | +| `data-ucc-bundle-item1-product-reference` | The unique reference of a product to add as a bundle item. | |
| 62 | +| `data-ucc-bundle-item1-product-variant-reference` | The unique reference of a product variant to add as a bundle item. | |
| 63 | +| `data-ucc-bundle-item1-quantity` | The amount of the given product to add as a bundle item. | |
| 64 | +| `data-ucc-bundle-item1-property1-key` | The key of a property to set on the added bundle item. | |
| 65 | +| `data-ucc-bundle-item1-property1-value` | The value of a property to set on the added bundle item. | |
| 66 | + |
| 67 | +Some attributes end with a number. This signifies that the attribute defines a collection and so multiple attributes can be defined with each distinct combination incrementing the number by `1`. It is important that these attributes start from `1` and must be sequential without gaps. |
| 68 | + |
| 69 | +With an add-to-cart button defined, clicking on the button will automatically add the product and open the cart for display. |
| 70 | + |
| 71 | + |
| 72 | + |
| 73 | +### Open Cart Button |
| 74 | + |
| 75 | +While the cart will open automatically when an item is added, you can also enable the customers to open their carts manually. To do this, add a `ucc-cart` class to a link or button element. The Umbraco Commerce Cart will then automatically bind a click event handler to trigger opening the cart. |
| 76 | + |
| 77 | +```html |
| 78 | +<a href="#" class="ucc-cart">Cart</a> |
| 79 | +``` |
| 80 | + |
| 81 | +### Cart Count Label |
| 82 | + |
| 83 | +Another common feature on commerce sites is the ability to display the total number of items in the current cart. To do this, define an HTML element with a `ucc-cart-count` class applied. Umbraco Commerce Cart will then automatically update its text value whenever the cart changes. |
| 84 | + |
| 85 | +```html |
| 86 | +<a href="#" class="ucc-cart">Cart (<span class="ucc-cart-count">0</span>)</a> |
| 87 | +``` |
| 88 | + |
| 89 | +## Commands |
| 90 | + |
| 91 | +As well as the automatic API defined above, it is possible to trigger Umbraco Commerce Cart commands manually via a number of JavaScript functions. |
| 92 | + |
| 93 | +```javascript |
| 94 | +// Open the cart |
| 95 | +UCC.openCart(); |
| 96 | + |
| 97 | +// Close the cart |
| 98 | +UCC.closeCart(); |
| 99 | + |
| 100 | +// Re-bind UI API elements |
| 101 | +UCC.bind(); |
| 102 | + |
| 103 | +// Update the store configuration |
| 104 | +UCC.setStore('brewed'); |
| 105 | + |
| 106 | +// Update the checkout URL |
| 107 | +UCC.setCheckoutUrl('/new-checkout'); |
| 108 | + |
| 109 | +// Set whether to display prices inclusive or exclusive of sales tax |
| 110 | +UCC.showPricesIncludingTax(true); |
| 111 | + |
| 112 | +// Show a property in the cart |
| 113 | +UCC.showProperty('myProp'); |
| 114 | + |
| 115 | +// Change the language of the cart UI |
| 116 | +UCC.setLang('dk'); |
| 117 | + |
| 118 | +// Add or replace a localization dictionary |
| 119 | +UCC.addLocale('en', { |
| 120 | + key: 'value', |
| 121 | + ... |
| 122 | +}); |
| 123 | + |
| 124 | +// Set the error handler |
| 125 | +UCC.setOnError(msg => { |
| 126 | + console.log(msg); |
| 127 | +}); |
| 128 | +``` |
| 129 | + |
| 130 | +## Localization |
| 131 | + |
| 132 | +The cart UI supports being translated into any language. Out of the box, it comes with a default English translation, but additional locales can be configured. |
| 133 | + |
| 134 | +Localization is controlled via the `lang` attribute in the `<html>` tag of your site. |
| 135 | + |
| 136 | +```html |
| 137 | +<!DOCTYPE html> |
| 138 | +<html lang="fr"> |
| 139 | + <head> |
| 140 | + <title></title> |
| 141 | + </head> |
| 142 | + <body></body> |
| 143 | +</html> |
| 144 | + |
| 145 | +``` |
| 146 | + |
| 147 | +In the above example, Umbraco Commerce Cart will look for a French locale. If a given locale can't be found, then it will default back to English. |
| 148 | + |
| 149 | +Additional locales can be added either via the `UCC.init` method or by calling the `UCC.addLocale` command. |
| 150 | + |
| 151 | +```javascript |
| 152 | +// Init command example |
| 153 | +UCC.init({ |
| 154 | + store: 'blendid', |
| 155 | + checkoutUrl: '/checkout', |
| 156 | + locales: { |
| 157 | + fr: { |
| 158 | + cart_title: 'Mon Panier', |
| 159 | + close_cart: 'Fermer le panier (ESC)', |
| 160 | + checkout: 'Vérifier', |
| 161 | + taxes: 'Impôts', |
| 162 | + subtotal: 'Total', |
| 163 | + total: 'Total', |
| 164 | + shipping_and_discounts_message: "Calculez les frais d'expédition et appliquez des remises lors du paiement", |
| 165 | + remove: 'Retirer', |
| 166 | + cart_empty: 'Votre panier est vide', |
| 167 | + } |
| 168 | + } |
| 169 | +}); |
| 170 | + |
| 171 | +// Add locale command example |
| 172 | +UCC.addLocale('fr', { |
| 173 | + cart_title: 'Mon Panier', |
| 174 | + close_cart: 'Fermer le panier (ESC)', |
| 175 | + checkout: 'Vérifier', |
| 176 | + taxes: 'Impôts', |
| 177 | + subtotal: 'Total', |
| 178 | + total: 'Total', |
| 179 | + shipping_and_discounts_message: "Calculez les frais d'expédition et appliquez des remises lors du paiement", |
| 180 | + remove: 'Retirer', |
| 181 | + cart_empty: 'Votre panier est vide', |
| 182 | +}) |
| 183 | +``` |
| 184 | + |
| 185 | +The default English locale has the following values and defines the required keys for a locale. |
| 186 | + |
| 187 | +```javascript |
| 188 | +{ |
| 189 | + cart_title: 'My Cart', |
| 190 | + close_cart: 'Close Cart (ESC)', |
| 191 | + checkout: 'Checkout', |
| 192 | + taxes: 'Taxes', |
| 193 | + subtotal: 'Subtotal', |
| 194 | + total: 'Total', |
| 195 | + shipping_and_discounts_message: 'Calculate shipping and apply discounts during checkout', |
| 196 | + remove: 'Remove', |
| 197 | + cart_empty: 'Your cart is empty', |
| 198 | +} |
| 199 | +``` |
| 200 | + |
| 201 | +To override a locale you can re-add it by reusing the same language key. |
| 202 | + |
| 203 | +```javascript |
| 204 | +// Init command example |
| 205 | +UCC.init({ |
| 206 | + store: 'blendid', |
| 207 | + checkoutUrl: '/checkout', |
| 208 | + locales: { |
| 209 | + en: { |
| 210 | + ...UCC.defaultLocales.en, // Clone the default locale |
| 211 | + remove: 'Remove item', // Update the `remove` key value |
| 212 | + } |
| 213 | + } |
| 214 | +}); |
| 215 | + |
| 216 | +// Add Locale command example |
| 217 | +UCC.addLocale('en', { |
| 218 | + ...UCC.defaultLocales.en, // Clone the default locale |
| 219 | + remove: 'Remove item', // Update the `remove` key value |
| 220 | +}) |
| 221 | +``` |
| 222 | + |
| 223 | +## Displaying Properties |
| 224 | + |
| 225 | +If you capture any custom properties, you may want to display them within the cart. Displaying properties is achieved in two steps. |
| 226 | + |
| 227 | +First, you define the property keys you wish to display either via the `UCC.init` command, or the `UCC.showProperty` command. |
| 228 | + |
| 229 | +```javascript |
| 230 | +// Init command example |
| 231 | +UCC.init({ |
| 232 | + store: 'blendid', |
| 233 | + checkoutUrl: '/checkout', |
| 234 | + properties: [ 'message' ] |
| 235 | +}); |
| 236 | + |
| 237 | +// Show property command example |
| 238 | +UCC.showProperty('message'); |
| 239 | +``` |
| 240 | + |
| 241 | +Next, you define a localization key to use as a label for each property. |
| 242 | + |
| 243 | +```javascript |
| 244 | +// Init command example |
| 245 | +UCC.init({ |
| 246 | + store: 'blendid', |
| 247 | + checkoutUrl: '/checkout', |
| 248 | + properties: [ 'message' ], |
| 249 | + locales: { |
| 250 | + en: { |
| 251 | + ...UCC.defaultLocales.en, // Clone the default locale |
| 252 | + property_message: 'Message', // Provide a key translation prefixed with `property_` |
| 253 | + } |
| 254 | + } |
| 255 | +}); |
| 256 | + |
| 257 | +// Show property + add locale command example |
| 258 | +UCC.showProperty('message'); |
| 259 | +UCC.addLocale('en', { |
| 260 | + ...UCC.defaultLocales.en, // Clone the default locale |
| 261 | + property_message: 'Message', // Provide a key translation prefixed with `property_` |
| 262 | +}) |
| 263 | +``` |
| 264 | + |
| 265 | +Now, when the cart is displayed, the defined properties will be displayed using the localization value as their label. |
| 266 | + |
| 267 | + |
| 268 | + |
| 269 | +## Theming |
| 270 | + |
| 271 | +To allow customization of the cart UI, CSS variables are used to allow overriding of the default styles. |
| 272 | + |
| 273 | +The following details the default values, and the available keys to override. |
| 274 | + |
| 275 | +```css |
| 276 | +:root { |
| 277 | + |
| 278 | + /* Colors */ |
| 279 | + --ucc-primary-color: #155dfc; |
| 280 | + --ucc-primary-color-light: #51a2ff; |
| 281 | + --ucc-primary-color-dark: #193cb8; |
| 282 | + --ucc-danger-text-color: #9f0712; |
| 283 | + --ucc-danger-background-color: #ffc9c9; |
| 284 | + |
| 285 | + /* Font */ |
| 286 | + --ucc-font-family: ui-sans-serif, system-ui, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji', sans-serif; |
| 287 | + |
| 288 | + /* Text */ |
| 289 | + --ucc-text-color: #364153; |
| 290 | + --ucc-text-color-light: #99a1af; |
| 291 | + --ucc-text-color-lighter: #c1c7d0; |
| 292 | + --ucc-text-color-dark: #101828; |
| 293 | + --ucc-text-lg: 20px; |
| 294 | + --ucc-text-md: 16px; |
| 295 | + --ucc-text-sm: 14px; |
| 296 | + |
| 297 | + /* Borders */ |
| 298 | + --ucc-border-color: #ddd; |
| 299 | + --ucc-border-radius: 5px; |
| 300 | + |
| 301 | + /* Components */ |
| 302 | + --ucc-button-background-color: var(--ucc-primary-color); |
| 303 | + --ucc-button-text-color: #fff; |
| 304 | + --ucc-button-background-color-hover: var(--ucc-primary-color-dark); |
| 305 | + --ucc-button-text-color-hover: #fff; |
| 306 | + --ucc-button-background-color-disabled: #d1d5dc; |
| 307 | + --ucc-button-text-color-disabled: #fff; |
| 308 | + --ucc-modal-width: 550px; |
| 309 | + --ucc-modal-background-color: #fff; |
| 310 | + --ucc-modal-overlay-color: rgba(0, 0, 0, 0.5); |
| 311 | +} |
| 312 | +``` |
| 313 | + |
| 314 | +Styles can be overridden by including a stylesheet after the Umbraco Commerce Cart stylesheet, replacing the desired keys. |
| 315 | + |
| 316 | +```html |
| 317 | +<link href="/App_Plugins/UmbracoCommerceCart/umbraco-commerce-cart.css" rel="stylesheet"> |
| 318 | +<style> |
| 319 | + :root { |
| 320 | + --ucc-button-background-color: #4FD1C5; |
| 321 | + --ucc-button-background-color-hover: #38B2AC; |
| 322 | + } |
| 323 | +</style> |
| 324 | +``` |
| 325 | + |
| 326 | +## Error Handling |
| 327 | + |
| 328 | +By default, Umbraco Commerce Cart will log any request errors to the console. If you would like to display errors to your users or handle them differently you can provide an error handler function. |
| 329 | + |
| 330 | +```javascript |
| 331 | +// Init command example |
| 332 | +UCC.init({ |
| 333 | + store: 'blendid', |
| 334 | + checkoutUrl: '/checkout', |
| 335 | + onError: (msg) => console.log(msg) |
| 336 | +}); |
| 337 | + |
| 338 | +// Set on error command example |
| 339 | +UCC.setOnError(msg => console.log(msg)); |
| 340 | +``` |
