Discover efficient ways to set up pagination for API responses in Xano. This step-by-step guide helps you handle your data smoothly every time.
In Xano, setting up pagination for API responses plays a crucial role in efficient data management and boosts performance by dividing large data sets into smaller, easier-to-handle portions. To achieve this, it’s essential to tweak your API endpoints so they can support pagination parameters, like page and limit. The next step involves creating logic that fetches the right data subset according to these parameters. Grasping how to configure pagination can significantly enhance your API’s speed and offer a smoother experience for users trying to access the data.
First things first, log in to Xano and head over to your project where you need to add pagination to an API endpoint.
Next, go to the "API" section in your project dashboard. Find the specific API endpoint that needs pagination and open it up.
Now, locate the data query within the API endpoint. This is usually a Database Request or Query all records action. Make sure it's set to fetch the right database collection or table.
Time to add some pagination parameters. You'll typically need limit and offset to control how many records per page and where to start. Here's what you need:
limit: Number of records per page.offset: Starting index of the records.Set these as inputs in your API schema.
Edit the data query to use the pagination parameters.
limit parameter: {{input.limit}}.offset parameter: {{input.offset}}.Make sure the API endpoint input schema includes limit and offset.
limit (type: integer) and offset (type: integer).limit to 10 and offset to 0.Head over to the "Test" tab for your API endpoint and try it out with different values for limit and offset to make sure pagination works.
{ "limit": 10, "offset": 0 }{ "limit": 10, "offset": 10 }Check if the API returns the correct subset of records.
For better usability, return the total count of records available. Xano lets you use aggregate functions to get the total count.
Example output structure:
{
"total": 100,
"data": [
// paginated records here
]
}
Review all your settings and save the changes to the API endpoint. Make sure everything is set up correctly and test one more time to confirm it works.
Update your API documentation to include instructions on how to use the pagination parameters (limit and offset). This helps developers using the API understand how to request paginated data properly.
