![]() Now that we have an object with details for the first application we can start to update our text layers. You can check the JSON results by clicking on the of each of these patches to see how we are filtering through the JSON. ![]() Right click on this Splitter and change its type to JSON then rename the patch to Item. For now we’ll add and connect a Splitter to the Value output. Later in this lesson we’re going to build a list of results and replace this Value at Index with a Loop Over Array patch. We want the first result of this Array so we’ll keep the Index input as 0. Next we’ll add a Value at Index patch and connect the Value output of the Value for Key to the Array input. We’ll use the patches mentioned above to return details for just the first application in this JSON.ĭo this by inserting a Value for Key patch and connecting the Result output from the Network Request patch to the Object input of this Value for Key patch, then set the Key input to results. ![]() If you scroll though the JSON you’ll see a lot of data, starting with a results Object. As you start to work with more complex data, you can use the Value at Path patch to combine both indexes and keys. Say we want to return the USD value, we would use a Value for Key patch and set the Key input to be Currency. To access values from an object in Origami, you can use the Value for Key patch. ArraysĪrrays store values between two square brackets as shown in this example: Although these formats have a lot in common we access the values from an array or an object with different patches. Both store multiple types of data, including text, numbers, booleans, and more. JSON stores data in two different formats: an Array or an Object. For more information about JSON, visit this JSON Overview Tutorial. The displayed result is in a format called JSON, which is a readable, compact and efficient format commonly used for exchanging data between applications and servers. You can check this data out by clicking on the value beside the Result output. Restart the prototype by clicking the refresh button on the viewer’s toolbar ⌘ R, the Network Request patch will now load new data from Apple’s iTunes Search API. Add this patch and connect its output to the Request input of the Network Request patch. We want to request data every time the prototype starts, so we’ll use the When Prototype Starts patch. Paste the following URL into the URL input of the Network Request patch: To receive data from the Network Request patch we need to add an URL input (an endpoint) and then tell the patch to request data from this URL. Setting up the data sourceīegin by selecting the patch editor and adding a Network Request patch by pressing ⌥ ⏎ Once you have live data in Origami, you can use it to fill content, generate views, and bind data to different layer properties. The Network Request patch allows you to request live data in Origami from a variety of sources. Download the starter tutorial files to follow along as we rebuild this prototype. If you have already been through Introduction to Loops, this tutorial will show you how to bridge live data with loops. We’ll use this data to update text and images while generating a looped list of applications. In this tutorial, we’ll build an App Store prototype that downloads live data from Apple’s iTunes Search API using the Network Request patch. Using live data is a great way to make your prototypes feel more realistic.
