11/02/2021, 12:05 PMWhat do you do to support multiple cdk versions

11/02/2021, 12:27 PM@Simon Reilly what kind of things do you share?
t
thdxr
11/02/2021, 12:43 PMYou can specify a peer dependency for cdk libraries
thdxr
11/02/2021, 12:43 PMThat allows flexibility for the version people are using instead of bundling it

11/02/2021, 1:02 PM@thdxr nice, this is what I was thinking š

11/02/2021, 1:03 PM@AdriƔn Mouly working on a set of common utils:
ā¢ Cognito configured for multi-tenancy
ā¢ Custom resource to forward secrets to Vercel supporting preview environments
Want to move fast with new SaaS projects, and not get bogged down in the boiler plate

11/02/2021, 1:03 PMNice.

11/02/2021, 1:03 PMDo you have multiple repos?
AdriƔn Mouly
11/02/2021, 1:03 PMIām using mono-repo, but might need to separate it.

Simon Reilly
11/02/2021, 1:04 PMI want to create one mono-repo for my utils, that I can pull in to any project
Simon Reilly
11/02/2021, 1:04 PMSo my projects would be separate repos

AdriƔn Mouly
11/02/2021, 1:04 PMI see.
AdriƔn Mouly
11/02/2021, 1:05 PMAnd how you planning on sharing resources?
AdriƔn Mouly
11/02/2021, 1:05 PMI mean.
AdriƔn Mouly
11/02/2021, 1:05 PMLike references.
AdriƔn Mouly
11/02/2021, 1:05 PMNot the implementation.
s
Simon Reilly
11/02/2021, 1:06 PMBit confused by the question. I am planning to just have one node module I can run yarn add in my new projects and not need to reimplement my utils

thdxr
11/02/2021, 1:23 PM@Simon Reilly I did the same thing lol, I have some shared resources across projects
a
AdriƔn Mouly
11/02/2021, 1:48 PM@Simon Reilly sorry, what I mean isā¦ for example if you create an API, and want to share that ārootā with other APIs that can extend itā¦ how you do it? or if you have a Website and want to reference an API created on other project.

11/02/2021, 3:49 PM@AdriƔn Mouly I think there are many ways to solve that problem. Cfn import/export. Static lookup methods (see aws-cdk/aws-ec2 Vpc construct). Personally I would be looking for isolation, so not a problem for me atm
a
AdriƔn Mouly
11/02/2021, 4:01 PMOk, yes, lookup is what I do for VPC.

11/02/2021, 4:07 PMI used to, and I stopped when I moved to sst. It was a normal npm module.
as much as I liked writing my own general purpose constructs, I now rarely find myself writing something generic enough that the sst team hasn't implemented it yet. when I will find such a use case, I'd love to contribute to the project.
and also, if it's for compliance reasons, this has a few words about that: https://aws.amazon.com/blogs/devops/best-practices-for-developing-cloud-applications-with-aws-cdk/
