StringJoiner

Join multiple string inputs into a single string output.

Work in Progress

We're working on adding pipeline examples and most common component connections.

Key Features

• Accepts multiple variadic string inputs and joins them into a single output string.

Configuration

1. Drag the StringJoiner component onto the canvas from the Component Library.
2. Click on the component to open the configuration panel.
3. On the General tab, no configuration is required.

Connections

StringJoiner accepts multiple string inputs through its input_str variadic input. Connect any component that outputs a string.

It outputs the joined string as output. Connect it to any downstream component that accepts a string input.

Source Code

To check this component's source code, open string_joiner.py in the Haystack repository.
