This is a helper package that sets up the correct configuration for starting flow automatically. This package doesn't download any binaries. It expects one of your folders in your window to contain:
- a .flowconfig file
- a node_modules/.bin/flow file (or symbolic link)
If there exists a folder where both of these conditions are met, only then is your flow language server started in javascript and javascriptreact files.
To obtain a modern javascript syntax with flow types, use JSCustom.
