A Step-by-Step Guide: Building Your First Bedrock Flow with Inline Code

Ready to add some custom logic to your Amazon Bedrock flows? Inline code nodes let you do just that, no external services required. Let's build a simple flow to translate text using inline Python.

Setting Up Your Flow

• Create a New Flow: In the Bedrock console, start a new flow.
• Add an Input Node: Define an input parameter, say text_to_translate (string type), where users will enter the text.
• Insert the Code Node: Drag and drop an "Inline Code" node onto the canvas. This is where the magic happens!

Writing Your Inline Code

• The Code: Copy and paste the following Python snippet into the code editor. It's a basic example—feel free to get more creative.

python
import boto3
translate = boto3.client('translate')
response = translate.translate_text(
    Text=input_data['text_to_translate'],
    SourceLanguageCode='en',
    TargetLanguageCode='es'
)
output_data = {'translated_text': response['TranslatedText']}

• Input/Output Parameters: Notice input_data and output_data. These are the bridges between your flow and your code. input_data['text_to_translate'] fetches the text from the input node.

> Best Practice: Keep your code snippets concise and focused. For complex tasks, consider using code assistance tools to generate and refine your code.

Testing and Debugging

• Define Input: Provide sample text in the "Input" section of the flow editor (e.g., "Hello, world!").
• Run the Flow: Execute the flow and check the "Output" section of the code node. You should see the translated text.
• Debugging: Bedrock provides basic error messages if your code fails. Double-check your syntax and dependencies.

Outputting the Results

• Add an Output Node: Connect the code node to an output node.
• Define Output: Configure the output node to display the translated_text from the code node's output_data.

With inline code nodes, Amazon Bedrock Flows just became infinitely more flexible. Go forth and create! You can also explore other AI Tools to incorporate into this code node!
