Lambda Browser
The Lambda view shows how each function is configured and lets you invoke it and adjust it on the spot.
Functions
Section titled “Functions”The function list shows name, runtime, memory, timeout, code size, state and last modified, with a filter and sorting. Opening a function shows its ARN, runtime and state, with tabs for:
- Configuration: handler, memory, timeout, architectures, IAM role, package type, tracing, VPC, log group, environment variables and layers.
- Code: size, SHA-256 and a Download code package button (zip-packaged functions; container images have no package to download).
- Aliases & Versions.
- Event sources: the queues, streams and tables that trigger the function, with state, batch size and the last processing result.
- Tags.
Invoke
Section titled “Invoke”Invoke runs the function synchronously with a JSON payload. Start from a template (API Gateway, S3, SQS, CloudWatch Events) or write your own. The result shows the status code, the version that ran, any function error, the response payload and the last 4 KB of the function’s logs.
Invoking runs the function’s code, which can change anything its role allows. Invoke stays available in read-only mode, so be deliberate about using it against a real account.
Edit configuration
Section titled “Edit configuration”Edit configuration changes the description, handler, runtime, memory (128 to 10,240 MB), timeout (1 to 900 seconds) and environment variables. Only the fields you change are sent.
