We’re migrating a code base to use the
async/await, and we have found some developers accidentally create functions returning
promise<promise<...>> because they forget to use
await at some point.
I would like to have a check in our pipeline that finds those
promise<promise<'a>> and generate a warning in the PR.
Is there a way to get the type info from a module using a cli tool?
No official tool yet, the CLI tool you want is currently in development.
For now you could use the rescript-editor-analysis.exe from rescript-vscode’s GitHub actions. E.g. download and unzip the ubuntu-20.04 artifact and put it in your repo.
Usage (needs both path to
.res and compiled interface file
./rescript-editor-analysis.exe createInterface src/MyFile.res lib/bs/src/MyFile.cmi
Disclaimer: It is an internal tool, API is subject to change!.
