fp-ts 🚀 - Who's using fp-ts?

Brettm12345 on 5 Feb 2020

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.

It is not a company... but, Marble.js framework integrates deeply with fp-ts.

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.

At facile.it (logo) we use it in particularly in our b2b application collaboratori.facile.it. Mainly in the frontend web app but also in some backend service. All repositories are private.

siuvdlec on 5 Feb 2020

We use fp-ts and io-ts to build data visualizations at Interactive Things (logo). Sadly, these repos are all private 😞 These are some public projects that use it, however:

We're learning fp-ts for future use.

I'm using fp-ts for a number of libraries, both personal and for a small business I'm working on. I hope to make some of these public libraries in the near future.

No public repos yet.

Feel free to use the logo in the github org page!

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.

We use this loads, and also io-ts.

Our company is called Candide, and we make a social network for people that need help looking after plants or want to help others. It's all incredibly wholesome!

@herp-inc utilizes fp-ts and its ecosystem (including io-ts, fp-ts-routing, parser-ts) in several projects, especially along with Cycle.js in front-end implementation, but also in server-side.

At Mapillary (@mapillary) we use fp-ts,io-ts in all our TypeScript back-end services in some form. Some services also use newtype-ts. @mikearnaldi's matechs-effect is a next step for us I guess :wink:. Repositories are private, sorry. https://mapillary.com is where we're at and here is our logo.
