Replacing a libdef with a custom one, robustly

How do I replace a libdef with a custom one of my own creation? I still want the full benefit of all the other libdefs.

Equivalently, I’d like to remove one libdef, but I don’t want subsequent updates of my libdefs to undo the replacement. It seems to me that simply deleting the libdef from the flow-typed directory would suffer this problem.

The number of challenges I’m having with the Express libdef has grown to the point where I just don’t see how I’m going to be able to use it. All I want are limited views of the request and response objects, extended with my session information and utility methods.

@jtlapp Did you actually remove the flow-typed/npm/express_v4.x.x.js? If you have two files doing a declare module 'express' it may take one of them… but not both.

Also, what is your [libs] configuration?

EDIT: Here is a project I recently contributed to, which had the same problem as you, but with lodash: https://github.com/styled-components/styled-components/tree/add-flow-dist/flow-typed

This broke in flow 0.53 for me.
