String Op
Runs on: Shared — pure logic, runs on the Community backend or inside a chatbox overlay.
The String Op node applies a text transformation to an input string. It supports a wide range of operations, from simple formatting like making text uppercase to more advanced manipulations like find-and-replace and regex patterns. This is your go-to node for any kind of text processing within a flow.
Inputs
| Name | Type | Description |
|---|---|---|
Input | string | The text to transform |
Arg | string | An argument used by certain operations (e.g., the replacement text for replace, the search term for indexOf) |
Outputs
| Name | Type | Description |
|---|---|---|
Result | string or number | The transformed result. Most operations return a string, but length and indexOf return a number. |
Configuration
- Operation: The transformation to apply. Options:
- uppercase -- Converts all characters to uppercase
- lowercase -- Converts all characters to lowercase
- trim -- Removes whitespace from the beginning and end
- concat -- Appends the Arg value to the end of the input
- replace -- Replaces the first occurrence of Arg in the input (use regex replace for advanced patterns)
- split -- Splits the string by the Arg delimiter and returns an array
- length -- Returns the number of characters in the input
- indexOf -- Returns the position of Arg within the input, or -1 if not found
- slice -- Extracts a portion of the string using Arg as the start and end positions (e.g., "0,5")
- regex replace -- Replaces text matching a regex pattern defined in Arg
Example
You want to display a viewer's username in all caps in a custom alert. Connect the trigger's username output to the Input handle, set the operation to uppercase, and connect the Result to your alert's display name field. "nightbot" becomes "NIGHTBOT".
