VSCode Plugin

Installation

• Install the extension from the VSCode marketplace.​

• Sign up for Thundra and select the Thundra Debugger option to receive your authentication key. If you’ve already signed up, you can get your key from the settings page.

• Open the Command Palette (⇧⌘P) and select the Thundra: Edit Configuration command to modify the configuration file.

• Set your authentication key to the variable “authToken” in your Thundra configuration file.

debug-client.json
{
    "profiles": {
        "default": {
            "debugger": {
                "authToken": <set-your-thundra-auth-token>,
                "sessionName": "default",
                "brokerHost": "debug.thundra.io",
                "brokerPort": 443
            }
        }
    }
}

How to use

• Set a debugging point on your AWS Lambda function.

  Execute the command Thundra: Start Debugger to start the debugging session. (Alternatively, you can click on the Start Thundra Debugger button on the Status Bar.)

• Now invoke your AWS Lambda function to hit on the debugging point.

• The debugging session ends when your AWS Lambda function times out. You can update the timeout of your function for longer sessions.

• To manage your Thundra Debugger profiles:

  • Open the Thundra configuration file by executing the command Thundra: Edit Configuration.

  • Add new profiles to the file as shown below.

• You can change your active profile by executing the command Thundra: Change active profile to use the Thundra Debugger with different configurations.

In order to quickly start with a different session name:

• Execute the command Thundra: Start Debugger (with a session name)

• Enter a unique session name (this will not make changes to the configuration file).

• Invoke the Lambda function and start debugging.

Commands

You can access all of the above commands from the command palette (Cmd+Shift+P or Ctrl+Shift+P).
