How To Use the JavaScript Fetch API to Get Data

There was a time when XMLHttpRequest was used to make API requests. It didn’t include Promises, and it didn’t make for clean JavaScript code. Using jQuery, you could use the cleaner syntax of jQuery.ajax(). Now, JavaScript has its own built-in way to make API requests. This is the Fetch API, a new standard to make server requests with Promises, but which also includes additional features. In this tutorial, you will create both GET and POST requests using the Fetch API.

Conditional statements in Liquid

The foundation of conditional statements can be boiled down to this: if this is true then run this code. You can also expand on that: if this is true then run this code, if not run a different code. You can get carried away on different ways to mold a statement.

Theme app extensions now support conditional app blocks

The visibility of an app block, or app embed block, of a theme app extension can now be controlled based on a custom condition. The condition can be included in the block's schema with the available_if attribute, and the state of the condition is stored in an app-owned metafield. The metafield can be accessed through the Liquid app object.

Tip of the Week

Auto Apply Discount Codes

Here's a technique for auto applying discounts and having them reflected in the cart that doesn't require Shopify Plus.

Call fetch(‘/discount/YOUR-CODE’).

That will create a discount_code cookie for the site. Shopify reads that at the checkout screen. On the front end you can use this snippet to pull the current discount.

Once you read the discount code do some logic to show the correct pricing in the cart. This is Hardcoded but the user won’t know the difference and will feel like they applied the discount before checkout.

Thanks to Celso White for the excellent tip!
