The Twilight JS SDK (@salla.sa/twilight) is the core package of the Twilight Framework, providing a comprehensive JavaScript interface for Salla's storefront APIs. It enables theme developers to easily communicate with Salla's backend services, handle events, manage state, and build interactive e-commerce experiences.
The Twilight Framework consists of several packages working together:
1. @salla.sa/base: Foundation layer with core utilities and services
2. @salla.sa/twilight (this package): Main SDK for Salla themes
3. @salla.sa/twilight-components: Web components for Salla themes
4. @salla.sa/twilight-tailwind-theme: Tailwind CSS theme for Salla themes
5. @salla.sa/applepay: Apple Pay integration for Salla
This modular architecture allows for better separation of concerns, more maintainable code, and the ability to use only the parts of the framework that are needed for a specific application.
- API Integration: Pre-built methods for all Salla API endpoints
- Event System: Powerful event handling for real-time updates
- Authentication: Seamless user authentication and session management
- Cart Management: Complete shopping cart functionality
- Multilingual Support: Built-in localization capabilities
- Version Management: Easy access to package versions via Salla.versions
- Optimized Bundle: Tree-shakable modules for minimal production builds
#### Twilight Themes
In case of using the Twilight JS SDK inside the Twilight themes, the developer doesn't need to include the Twilight JS SDK in the theme project's bundle or inside the html, Twilight theme engine will inject the latest version of the Twilight JS SDK in the page.
Basically, the developer does not need to call the method salla.init() for twilight themes, because it will be called automatically upon the installation of the Twilight theme engine. This is done thanks to the body:end hook {% hook 'body:end' %}.
#### HTML and CDN
The most common approach for setting up the Twilight JS SDK is load it via befor closing the body tag of the HTML document.
``html title="Code Snippet"`
The following snippet of code will give the basic version of the SDK where the configurations are set to their minimum requirements, for example, store URL. The method salla.init() is used to setup and initialize the SDK.
`js`
#### Bundler/ES modules
The developer may also install the Twilight JS SDK using the following commands:
`npm title="NPM Installation Command"`
npm install @salla.sa/twilight --save
`yarn title="Yarn Installation Command"`
yarn add @salla.sa/twilight
Initially, the developer must import the Salla JS Events library as follows:
`js`
import '@salla.sa/twilight';
Similar to the HTML/CDN section, the following code snippet will give the basic version of the SDK where the configurations are set to their minimum requirements, wherein the method salla.init() is used to setup and initialize the SDK.
`js`
As a result of the SDK initialization, the developer will be able to use any of the SDK's main APIs. For example, the method addItem adds an item into the cart, the developer may call the method addItem as follows:
`js`
salla.cart.addItem({
id: 1234,
quantity: 1,
notes: "please i need to get the red color"
}).then((response) => {
/ add your code here /
});addItem
In addition to the above example, the method may adds an item with multiple options to the carts as follows:`js`
salla.cart.addItem({
id: 1234,
quantity: 1,
options: {
117414452: 11232214, // option value id (select choice)
117416632: "http://option-value-as-url-of-image.com",
117411132: "option value as string"
},
notes: "please i need to get the red color"
}).then((response) => {
/ add your code here /
});
Furthermore, a large number of store events will be available for use. Thus, the developer's theme may be configured to respond automatically to a variety of activities, such as:
- The user requested an Access Code to perform a login, however, the code was not sent. For this scenario, using the method salla.event.auth.onCodeNotSent() can be used.
- A new item has been added to the cart via the salla.cart.event.onItemAdded() method.
- The user added a new item to the Wishlist using the method salla.event.wishlist.onAdded().
Full example for that would be the event onItemAdded which is triggered when adding an item to the cart is done without having any errors coming back from the backend:`js`
salla.cart.event.onItemAdded((response) => {
console.log(response)
});onItemAddedFailed
On the over hand, the event is triggered when adding an item to the cart is not completed and an error has occurred. For example, the id of the product to be added to the cart was not found.`js`
salla.cart.event.onItemAddedFailed((errorMessage) => {
console.log(errorMessage)
});
Aside from calling the APIs, the developer has the ability to configure the Twilight engine to meet the needs of his theme. This list of the available configurations can be found in this article. For this purpose, the method salla.config.get() is used to retrieve a configuration value, while salla.config.set() is used to set a configuration value.
#### Set configuration value
The developer may set the debug mode to be activated. That is to state, the theme will be run in a debugger. This means that the debugger keeps track of everything that happens while the theme is running.
`js`
salla.config.set('debug', true)
#### Get configuration value
Similarly, the developer can use the method salla.config.get() to get any value from the configuration file. To retrieve a simple value such as the user Id, the following syntax can be followed:
`js`
salla.config.get('user.id’)
Furthermore, if the required value is nested inside an inner value, such as a currency code, the following syntax can be followed:
`js`
salla.config.get('currencies.SAR.code’)
#### Accessing Version Information
The Twilight Framework provides easy access to version information for all packages through the Salla.versions object:
`js
// Get the version of the core package
console.log(Salla.versions.twilight); // e.g., "v2.14.145"
// Get the version of the base package
console.log(Salla.versions.base); // e.g., "v2.14.143"
`
This is particularly useful for debugging, support, and ensuring compatibility between different parts of the framework.
