I met following error on yarn build at aws-iot 🤔

error: [awslint:no-unused-type:@aws-cdk/aws-iot.ActionConfig] type or enum is not used by exported classes (declared at lib/action.ts:19)
error: [awslint:no-unused-type:@aws-cdk/aws-iot.IAction] type or enum is not used by exported classes (declared at lib/action.ts:7)

And I confirmed this error was suppressed when using the IAction in TopicRule.

Shall we implement using the IAction in TopicRule as possible as simple? (ex. not implement addAction())

Yes, we should implement using IAction in this PR too (add actions: IAction[] to TopicRuleProps, and then use it inside TopicRule). If you want to implement TopicRule.addAction() in this PR, I'm fine with that too.

Now that we have the @aws-cdk/aws-iot-actions module on master, let's add a single implementation of IAction there, and use that in the ReadMe of @aws-cdk/aws-iot, instead of an anonymous object.

Can you use function.grantInvoke() instead?

@skinny85 Thank you for your review!

In my understanding, using addPermission() is better. Because a lambda resource policy created by using grantInvoke() is more lax than using addPermission().

As described in this document, lambda resource policy fields sourceAccount and sourceArn are required (or recommended?). But functions.grantInvoke() cannot add sourceAccount and sourceArn as this code.

For confirmation, I tried following code instead of this.func.addPermission():

this.func.grantInvoke({ grantPrincipal: new iam.ServicePrincipal('iot.amazonaws.com') });

Then there is template difference as following:

This is almost perfect @yamatatsu! Change the account in LambdaAction, and rename it to LambdaFunctionAction, and we'll merge this in!
