const cfnWebFunctionProps: lambda.CfnWebFunctionProps = {
  functionName: 'functionName',

  tags: [{
    key: 'key',

## Properties

- `functionName`: string (required) — The name of the web function.

  The name can contain letters, numbers, hyphens (-), and underscores (_), and cannot begin or end with a hyphen or an underscore. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

- `tags`: [CfnTag](/cdk/api/v2/docs/aws-cdk-lib.CfnTag.html)[] — A list of tags to apply to the function.
