'Go project containing Typescript AWS-CDK directory has cluttered go.mod file
I have a Go project containing a Typescript AWS-CDK directory to define the Stack that contains the Go binary.
The simplest project for this example is:
mkdir example
cd example
mkdir infrastructure
cd infrastructure
cdk init app --language typescript
cd ..
go mod init example
go mod tidy
At this point, go.mod is full of aws-cdk-go references (despite the fact I'm using Typescript). Ideally, go.mod shouldn't have any dependencies at this point. It appears that there are several Go files buried in the node_modules/aws-cdk/.... path that may be influencing go mod tidy.
I'm not yet interested in using the Go CDK libraries. Besides throwing all of my Go code into a subfolder and only running go mod init in that subfolder, is there a way to prevent go mod tidy from referencing those buried files?
Solution 1:[1]
An empty go.mod in a directory will cause that directory and all of its subdirectories to be excluded from the top-level Go module.
In the infrastructure directory, touch go.mod creates an empty file and if I go mod tidy in the root folder, the go.mod file only contains the modules my project actually uses.
Solution 2:[2]
go mod init looks for configuration files and, if found, installs the modules.
Avoid this "helpful" behaviour by running go mod init [Edit] before cdk init app in a subdirectory:
# ...
npx cdk init app --language typescript
cd ..
mkdir src
cd src
go mod init example
go mod tidy
cd ..
This creates an empty go.mod, as expected.
