Helpers

The Twilight JS SDK is packaged with a variety of helpful functions that may be accessed and used straight within Templates. Previous articles in this documenation introduced Twilight Flavoured Twig. In this aricle we will go thourgh how to use the Helper functions using the Twilight SDK JS.

Url Helper

In general, the sall.url.get() helper function will return the absolute URL for the provided route, including the scheme and host.

salla.url.get(…)

Asset Helper

The salla.url.asset() function returns the public path of the specified asset (which can be a CSS file, a JavaScript file, an image path, etc.). This function looks at where the theme was installed (for example, if the theme is accessed in a subdirectory of the host) and, if specified, the asset package base path. It needs to be supplied with the required file's path.

salla.url.asset(filePath)

CDN Helper

A content delivery network (CDN) referes to an external resource that can be used inside the theme. The The salla.url.cdn() function helps with doing that by passing the path of that external resource.

salla.url.cdn(filePath)

is_page Helper

This helper function determines whether if the passed route is a path, by using page slug

if(salla.url.is_page('index')) {
  console.log('you arrive 💪');
}

// other exmaple
if(salla.url.is_page('product.index')) {
  console.log('you arrive product index 💪');
}

:::info
You can find the page slug via views by {{ page.slug }}, or via browser console bysalla.config.get('page.slug')

Money Helper

The Money Helper is another function provided by the Twilight JS SDK that allows the developer to format a numeric value as a currency. The syntax for using this helper is salla.money(value), where value is the numeric value that you want to format as per the default currency.

For example, if you want to format the number 100 as a currency, you can use the following JavaScript code:

const moneyValue = salla.money(100); // formats 100 as per the selected currency
console.log(moneyValue); // output: "SAR 100"

If the Arabic numbers are enabled by the merchant the will be as follows:

console.log(moneyValue); // output: "١٠٠ ر.س"

You can also pass additional parameters to the salla.money() helper to customize the currency and locale settings, such as:

salla.money({amount:100, currency:"USD"}); // output: "USD100"

Number Helper

This helper formats any number given to an Arabic number if merchant enables it and the current language is Arabic. It will also parse decimal number representation to a decimal point in Arabic (,):

const numValue = salla.helpers.number(966567891011); 
console.log(numValue); // output: "٩٦٦٥٦٧٨٩١٠١١"

Apple Pay Helper

This helper allows checking multiple factors which are:

Is apple pay enabled in this store?
Does this browser support Apple pay?

The helper will return a value of true if Apple Pay is enabled, or false if it is not enabled.

var applePayEnabled = salla.helpers.hasApplePay();
if (applePayEnabled) {
    console.log("Apple Pay is enabled");
} else {
    console.log("Apple Pay is not enabled");
}

Is iframe

The helper function isIframe() determines whether a web page is being displayed within an iframe rather than a window. This function returns either true or false based on this condition.

function isIframe(){
return window.self !== window.top
}

Is Preview

isPreview() helper function is a wrapper for the above explained isIframe() helper function.

const isCustomizingTheme = salla.helpers.isPreview();
console.log(isCustomizingTheme); // prints true or false
