This is just an example that shows how to distribute flow types for modules
which use babel and/or rollup. In this example, we have src/browser-module
and src/node-module to demonstrate each. The rollup example could use the
flow gen-flow-files command except it suffers from
this issue.
So instead, you can forward all exports in a file with the same name with
.flow. See the output in the dist directory and the scripts in the
package.json.
I created this for this blog post
where I talk about doing this for my project paypal-scripts.
