so, with the new CDK v2, can we just update

aws-cdk-lib

and any related

-alpha

libraries as we normally would with npm & yarn? no need for

sst update

?

This is true even with CDK v1, so long as the version matches the SST version used.

true. so I guess the question is, how do we know what version of CDK is needed by SST?

i havent found a great answer for that, but l often just pull up the github repo and look, or dig into node_modules.

yeah, I was just thinking that. SST 0.60.4

node_modules/@serverless-stack/resources/package.json

contains aws-cdk-lib 2.7.0

correct, thats how I usually go about it. with CDK v1, you could just look at the peerDependencies complaining, but I think with so few that is no longer the case.

if you run

sst --version

it gives you the current SST version and the supported CDK version

ah! even better

just be careful about the global install

sst

vs the project

sst

(might be different versions)

Good point, I always run

./node_modules/.bin/sst --version

despite not having it installed globally

yep.

yarn sst

will run the local project’s version
