Discover the ins and outs of Xano's templating language to effortlessly craft dynamic, personalized content. Dive into our guide and start enhancing your apps today.
Xano's templating language lets users craft flexible, custom responses by embedding variables and logic straight into their application templates. With features like conditionals, loops, and filters, Xano allows developers to dynamically tweak output based on user input and data conditions. This level of functionality is crucial for building responsive, data-driven applications that can adapt in real time to user needs. Mastering these templating capabilities is essential for reaping the full benefits of Xano's powerful backend-as-a-service platform.
First things first, log in to your Xano account. Head over to the project where you want to use the templating language. Once you're in, go to the "Data" section and pick the API Endpoint you want to work with. Look for the "Response" section to define your endpoint's output.
Get comfy with Xano’s templating syntax. It uses double curly braces {{ }} for variable injection. You can do basic operations and conditionals within these braces.
In your response definition, use the double curly braces to inject variables. For example, to show a user’s name, you might write:
{
"message": "Hello, {{name}}!"
}
This will pop the value of the name variable right into the message.
Xano’s templating language lets you use conditional logic. Use {{#if condition}}...{{/if}} to render content based on conditions. For example, to check if a user is an admin:
{
"isAdmin": "{{#if user.is_admin}}true{{else}}false{{/if}}"
}
To handle lists or arrays, use {{#each collection}}...{{/each}}. For instance, to display a list of user emails:
{
"emails": [
"{{#each users}}",
"{{email}}",
"{{/each}}"
]
}
This will loop through the users collection and insert each user's email into the resulting JSON.
Xano's templating language supports nesting. You can include nested templates for more complex data structures:
{
"users": [
"{{#each users}}",
{
"name": "{{name}}",
"contact": {
"email": "{{email}}",
"phone": "{{phone}}"
}
},
"{{/each}}"
]
}
Always test your templates to make sure they render correctly. Use the "Run and Debug" feature in Xano to execute the endpoint and check the output. Compare the rendered response with the expected data to catch any issues.
Xano supports advanced features like custom functions, which can be used within templating. For example, using a helper function to format dates:
{
"formattedDate": "{{format_date created_at 'MM/DD/YYYY'}}"
}
Check out Xano’s documentation for a full list of available helper functions.
