Fixing broken type definitions

The talk

One-sentence summary

How to deal with incorrect third-party type definitions.

What's the format — is it a case study, a live coding session, a workshop or something else?

Case study.

Tell us more about the talk

In a perfect world, every library is created with TypeScript and the provided type definitions describe the API fully.

But we don't live in a perfect world. Sometimes types are not even there. Sometimes they are incomplete. Sometimes the version of type definitions doesn't match the actual API of the library. Sometimes they are written in such a way you cannot even augment them locally.

Yet we have no choice. The library is in use and removing it from the project just because it's poorly typed is not always possible.

What can you do?
