I've closed #648 as a duplicate.

Is this under way at all?

@eladb Even though Go support is not underway, yet (if I understood it correctly), it would be very nice to see this happen.

In my case, I need a struct for json marshal/unmarshal for cloudwatch DashboardBody.
I'm really surprised the GetDashboard aws cloudwatch api returns a json string for the body.

WTF right?

Yes please! This would be amazing if Go was supported! Any updates on this?

Is there a way we can contribute to this? I see lots of people +1 it, if just a small minority of them were able to help we'd probably have it by now.

I've published a simple PoC of GolangFunction construct here: https://github.com/RafalWilinski/aws-lambda-golang-cdk

Haven't figured out the JSII part yet, works only with TS-based stacks and Go ^1.11.

Feedback and contributions more than welcome.

Edit: Figured out the JSII part, works with all languages now!

"Working on it" 🥰

Developer Preview is here!

@ccfife is there any (vague) ETA on when Go support will reach GA? The story on the roadmap board only links to this issue and a closed/completed board for reaching developer preview.

Edit: I found this board linked from the above blog post: https://github.com/aws/jsii/projects/3

But it wasn't attached to the go issue on the roadmap, turns out I can edit that though, so I added the link

You may track the Go GA project board here. We would love to hear your feedback on the Dev Preview version!

Hi,
thank you very much for the effort you are putting in this. <3
I tried it but I didn't get anywhere.

Example use case: I was trying to deploy:

• SQS queue with DLQ and subscription to a SNS topic
• Lambda triggered by the previous point SQS queue
• Another lambda triggered by ApiGateway HTTP inside a VPC
• DynamoDB table
• Lambda triggered by scheduled CloudWatch event

Pain points:

• Documentation: besides the basic examples (still hard to understand without having a previous good knowledge of CDK) there's anything useful to start from
• Types: e.g. queue retention period RetentionPeriod: awscdk.Duration_Seconds(jsii.Number(1209600)), could be int, could be time.Time, and it's very difficult to get that jsii.Number(1209600) is what you need
• Credentials: SDK v2 let you do anything just by specifying the profile, here we need something like jsii.String(os.Getenv("CDK_DEFAULT_ACCOUNT")) and no profile

At this point there was already too much friction to get things done in a reasonable amount of time and I had to revert to Serverless.

I'd can't wait to see this project grow and shine in the future but for the moment, without docs, examples, and with unfriendly APIs it's quite hard to use. Maybe someone more skilled with CDK in another language would have a better experience.

[jonny-rimek]

not sure this is the place to post GA feedback.

I finally got to play around with the go version. I used CDK itself since GA and use it at work to manage our prod infrastructure.

Overall I enjoyed the experience, but it is noticeable that it's not built with go in mind and can at times look a bit awkward.

	testIntegration := awscdkapigatewayv2integrationsalpha.NewHttpLambdaIntegration(jsii.String("FirstTestIntegration"), firstTestFunction, &awscdkapigatewayv2integrationsalpha.HttpLambdaIntegrationProps{})

My only pain point, which is a pretty big one imo, is that you can't see the default values and if the value is required or not. Using TS the IDE tells me what values are must haves and what the default values are. As go doesn't have the possibility for either, you simply don't know, which is a huge bummer.

The easiest fix would probably be to duplicate both value into the description of the attribute.

I also tested pulumi in go and wasn't convinced, mostly because you just type the value as string, instead of having defined types and let your IDE show you what values are acceptable

e.g. cdk:

	awsdynamodb.NewTable(stack, jsii.String("Table"), &awsdynamodb.TableProps{
		PartitionKey: &awsdynamodb.Attribute{
			Name: jsii.String("PK"),
			Type: awsdynamodb.AttributeType_STRING,
		},
		SortKey: &awsdynamodb.Attribute{
			Name: jsii.String("SK"),
			Type: awsdynamodb.AttributeType_STRING,
		},
		BillingMode:   awsdynamodb.BillingMode_PAY_PER_REQUEST,
		RemovalPolicy: awscdk.RemovalPolicy_DESTROY,
	})

Summary:

I will continue to use the go version for my projects, but would recommend TS for everyone else, unless you are a huge go nerd and have previous cdk experience, otherwise you will probably have a hard time.

The whole dev experience is just more cohesive in TS and there are more examples for beginners to learn from.

hope that helps
