Debugging Liquid Code
Liquid debugging uses {{ content | json }} for Shopify theme inspection.
Introduction to Liquid Debugging
Liquid debugging is an essential technique for developers working with Shopify themes. It allows you to inspect and troubleshoot your Liquid code by converting your data into a JSON format, making it easier to understand and debug. This process helps identify issues, verify data, and ensure that your templates are rendering correctly.
Understanding {{ content | json }}
The {{ content | json }}
filter in Liquid allows you to output a variable or object as JSON. This is particularly useful for debugging because it provides a clear and structured view of your data. By converting complex Shopify objects into JSON, you can easily inspect their properties and values.
In the example above, the product
object is converted to a JSON string and stored in the product_data
variable. The pre
tag is used to display this JSON string in a readable format on your page.
Practical Debugging Example
Let's say you're working on a product page and something isn't displaying as expected. You suspect the issue might be with the product data not being passed correctly. Here's how you can use Liquid debugging to investigate:
By placing {{ product | json }}
within a div
, you can view the entire product object data in JSON format. This will help you verify whether all necessary properties are present and correct, allowing you to identify any discrepancies.
Debugging Tips and Tricks
- Use the browser console: Once the JSON is rendered on your page, you can copy it to your browser console for easier inspection and manipulation.
- Comment out sections: If you suspect an issue in a specific part of your Liquid template, comment it out and check if the issue persists.
- Check Shopify documentation: Ensure you're familiar with Shopify's Liquid objects and properties to better understand what your JSON output should look like.
