=head1 NAME

AWS::Lambda - Perl support for AWS Lambda Custom Runtime.

=head1 SYNOPSIS

Save the following Perl script as C<handler.pl>.

    sub handle {
        my ($payload, $context) = @_;
        return $payload;
    }
    1;

and then, zip the script.

    $ zip handler.zip handler.pl

Finally, create new function using awscli.

    $ aws --region "$REGION" --profile "$PROFILE" lambda create-function \
        --function-name "hello-perl" \
        --zip-file "fileb://handler.zip" \
        --handler "handler.handle" \
        --runtime provided.al2023 \
        --role arn:aws:iam::xxxxxxxxxxxx:role/service-role/lambda-custom-runtime-perl-role \
        --layers "arn:aws:lambda:$REGION:445285296882:layer:perl-5-38-runtime-al2023-x86_64:1"

It also supports L<response streaming|https://docs.aws.amazon.com/lambda/latest/dg/configuration-response-streaming.html>.

    sub handle {
        my ($payload, $context) = @_;
        return sub {
            my $responder = shift;
            my $writer = $responder->('application/json');
            $writer->write('{"foo": "bar"}');
            $writer->close;
        };
    }
