User Input Dialog

Category: Input/Output Data · Node Type ID: input-dialog

Prompts user for runtime input via dialog or fallback test value, of a user-selected type

Overview

Prompts the user for an interactive runtime value via a modal dialog when the workflow executes in the browser, or falls back to the configured default value when running in headless/automated test environments or when the dialog is dismissed.

Like Static Value, the node supports four primitive data types (Bytes, String, Int, and Bool) and adapts its output port type and default value field accordingly. An optional Trigger input port allows you to sequence the prompt so that it only appears after an upstream node has completed.

When to Use

Prompting for a passphrase, PIN, challenge code, or hex token interactively during a live demonstration or manual test run.
Sequencing an interactive confirmation or input step after an upstream key-generation or challenge node using the optional Trigger port.

Parameter Configuration

Parameter (ID)	Type & Default	Visibility Condition	Description & Options
Type `type`	`select` Default: `string`	Always visible	Data type of the value requested from the user and emitted by the `User Input` output port (`bytes`, `string`, `int`, or `bool`). `bytes`: Bytes (Hex) `string`: String (Text) `int`: Int (Number) `bool`: Bool (True/False)
Prompt Message `promptMessage`	`text` Default: `Enter value:` Supports Variable Reference (`$var`: `string`)	Always visible	Message text displayed inside the runtime input dialog box to explain what value the user should enter.
Default Value (Bytes) `defaultBytes`	`hex` Default: `00112233445566778899aabbccddeeff` Supports Variable Reference (`$var`: `bytes`)	When `type` is `bytes`	Fallback hex string pre-filled in the dialog and used in non-interactive runs when `Type = bytes`.
Default Value (String) `defaultString`	`textarea` Default: `Hello NodeCrypto` Supports Variable Reference (`$var`: `string`)	When `type` is `string`	Fallback text string pre-filled in the dialog and used in non-interactive runs when `Type = string`.
Default Value (Int) `defaultInt`	`number` Default: `0` Supports Variable Reference (`$var`: `int`)	When `type` is `int`	Fallback integer literal (parsed as `bigint`) used when `Type = int`.
Default Value (Bool) `defaultBool`	`select` Default: `false` Supports Variable Reference (`$var`: `bool`)	When `type` is `bool`	Fallback boolean value (`true` or `false`) used when `Type = bool`. `true`: True `false`: False

Port I/O Specification

See Ports & Connections for general wiring rules, data type colors, and dynamic port creation.

Input Ports

Port Nature: Fixed Input Ports (1 total).

Port Name	Port ID	Data Type	Required	Visibility Condition	Description
`Trigger`	`trigger`	`Any`	Optional	Always visible	Optional sequencing input of any data type. When connected, the dialog is only triggered after the upstream node connected to `Trigger` finishes.

Output Ports

Port Nature: Fixed Output Ports (1 total).

Port Name	Port ID	Data Type	Visibility Condition	Description
`Value`	`string`	`String`	Always visible	Emits the user-entered (or fallback default) value in the selected data type (`Bytes`, `String`, `Int`, or `Bool`).

Error Cases

This node has no runtime failure cases (errorProfile: none) and always succeeds for any valid typed input.

Examples

Interactive Passphrase Prompt for PBKDF2

Ask the user for a passphrase at runtime and derive a 256-bit key.

Set Type to String (Text) and Prompt Message to "Enter master passphrase:".
Connect the User Input output port to String to Bytes, then into the Password / Secret port of PBKDF2 Key Derivation.
