Object Node

Overview​

The Object Node allows you to create an object or array from input values and a JSON template. The node automatically escapes the input values and inserts them into the template.

This node is particularly useful for creating structured values from multiple inputs. It supports any data type as input and outputs an object or array.

Inputs​

TitleData TypeDescriptionDefault ValueNotes
(Dynamic)anyThe input values to be inserted into the JSON template. The input names are dynamically generated.N/AWhole unquoted placeholders preserve JSON values. Placeholders inside JSON strings are escaped as string content. The input names are extracted from the JSON template.

Example 1: Creating an object from multiple inputs​

  1. Create an Object Node and set the JSON Template to the following:

    {
      "name": "{{name}}",
      "age": {{age}},
      "job": "{{job}}"
    }

  2. Create two Text Nodes and set their values to John Doe and Engineer respectively. Connect them to the name and job inputs of the Object Node.

  3. Create a Number Node and set its value to 30. Connect it to the age input of the Object Node.

  4. Run the graph. The Output of the Object Node should be the following object:

    {
      "name": "John Doe",
      "age": 30,
      "job": "Engineer"
    }

Interpolation in JSON strings​

Use a placeholder as a whole JSON value when you want to preserve the input's data type:

{
  "rawValue": {{value}},
  "stringValue": "{{value}}"
}

You can also embed placeholders inside larger JSON strings:

{
  "message": "{{name}}. That's it."
}

When a placeholder is embedded in a JSON string, strings are inserted as text, non-string values are inserted as their JSON text, and null or undefined values are inserted as the text null. Quotes, backslashes, and newlines are escaped automatically so the final template stays valid JSON.

Error Handling​

The Object Node will error if the JSON Template is not a valid JSON string or if the interpolated JSON string (after inserting the input values) is not a valid JSON string.

FAQ​

Q: Can I use the Object Node to create an array?

A: Yes, you can use the Object Node to create an array by setting the JSON Template to a valid JSON array string. For example:

["{{value1}}", "{{value2}}", "{{value3}}"]

Q: How are the input values escaped?

A: The input values are automatically escaped by the Object Node. Whole unquoted placeholders insert JSON values directly. Whole quoted placeholders create JSON strings, converting non-string values to JSON text first. Placeholders embedded inside larger JSON strings are escaped as string fragments.
