Get Array Item

Get Array Item node is designed to extract a specific item from an array based on its index. This node is particularly useful when you need to access a particular element within an array for further processing or output in your workflow.

Properties Panel

Field	Description	Required
Node name	Node Name	true
Variable Name	The name of the variable where the extracted item will be stored	true
Item Index	The index of the item to be extracted from the array (0-based) -len(arr) <= i < len(arr)	true
Lookup Array	The array from which the item will be extracted	true

Usage

1. Specify a variable name where the extracted item will be stored.

2. Enter the index value of the item you want to extract (remember that array indices start at 0).

3. Provide the lookup array from which the item will be extracted.

Returns

The node stores the extracted item in the specified variable. You can access this using Magical Autocomplete (e.g., $.variables.<variable_name>) in any node below this node.

Example

Let's say you have an array of user objects fetched from database using List Records node and you want to extract the second user:

1. Set Variable name to second_user

2. Set Index value to 1 (remember, arrays are 0-indexed)

3. Set Lookup array to $.listRecords.result (assuming you're using List Records node and it's name is listRecords)

This will store the second user object in the variable second_user. You can then use this in subsequent nodes by $.variables.second_user

Best Practices

• Always ensure that the index value is within the bounds of the array. Attempting to access an out-of-bounds index may result in an error.

• Negative Index are supported for extracting values from back but make sure it's within the size of lookup-array.

• Remember that array indices start at 0, so the first item is at index 0, the second at index 1, and so on.

• If you need to access the last item in an array of unknown length, you can use -1 as index value.

• When working with potentially empty arrays, consider adding a condition to check the array length before attempting to extract an item.
