Filter: Create Object From Entries

Hey there! In this blog post, we'll dive into the exciting new "Create Object from Entries" filter in Xano. This handy feature allows you to take a set of data, filter through it, and return a new object with only the desired data. It's perfect for situations where you need to remove blank values or unwanted data from an object, like when working with third-party API responses.

Step 1: Understanding the Data

Let's start with an example JSON object that we'll be working with:

json
 {
  "A": 1,
  "B": 2,
  "C": "",
  "D": 3,
  "E": "",
  "F": 5,
  "G": 6
 }
 

As you can see, this object has several key-value pairs, but two of them ("C" and "E") are empty.

Step 2: Separating Keys and Values

The first step is to separate the keys and values of the object into separate arrays. We'll use the `entries` filter for this:

 entries
 

This filter gets the property entries of an object or array as a numerically indexed array of key-value pairs. After applying this filter, our data will look like this:

json
 [
  ["A", 1],
  ["B", 2],
  ["C", ""],
  ["D", 3],
  ["E", ""],
  ["F", 5],
  ["G", 6]
 ]
 

Step 3: Filtering Out Empty Values

Next, we'll use the `filter_empty` filter to remove the key-value pairs with empty values:

 filter_empty(value)
 

Here, we specify the `value` path to indicate that we want to filter out empty values from the value part of the key-value pairs.

After applying this filter, our data will look like this:

json
 [
  ["A", 1],
  ["B", 2],
  ["D", 3],
  ["F", 5],
  ["G", 6]
 ]
 

Step 4: Creating a New Object from Entries

Finally, we'll use the brand new "Create Object from Entries" filter to consolidate the filtered key-value pairs back into a single object:

 create_object_from_entries
 

This filter creates an object based on an array of key-value pairs, giving us our final result:

json
 {
  "A": 1,
  "B": 2,
  "D": 3,
  "F": 5,
  "G": 6
 }
 

And just like that, we've effortlessly filtered out the empty values from our original object!

Wrapping Up

The "Create Object from Entries" filter in Xano provides a seamless way to clean up your data and remove unwanted values from objects. Whether you're working with third-party API responses or any other data source, this filter can save you time and hassle by automating the process of data cleaning.
