At buildo (logo) we are using fp-ts in pretty much every TypeScript codebase that we have: React applications, Node services, internal CLI tools. The majority of the repositories is closed source. We are also using it in a few open source libraries: metarpheus-io-ts, avenger.

IO application is using fp-ts.

• Mobile application: https://github.com/pagopa/io-app;
• Backend: https://github.com/pagopa/io-backend.

There are other repositories, but these two are the main ones.

We use it for all our front and backend application. All private repos.

A framework we are currently using for front end development with fp-ts and React is our own implementation of the elm-ts pattern effe-ts. Currently in an evaluation phase. It extends elm-ts by the ReaderT pattern and an extended set of Monad instances for state management.

They probably don't even know that they have a chance to appear on fp-ts website 😄

We've been heavily using fp-ts in our App
Typescript with fp-ts made react-native codebase solid, even better than native ones.

Agile Digital (@agiledigital) is getting more and more use out of fp-ts and io-ts. Not much in public repos yet, but there certainly will be once we get our libraries to a slightly higher level of polish.

At lambdaworks we started to use fp-ts and are integrating it into our existing codebase.

Currently, our only project using fp-ts is lambert, our slack bot. We are using fp-ts to write functional serverless functions. The project is unfortunately not open-source.

In the future, we plan to use fp-ts both in our serverless functions and in our react applications.
