Flow Type Cheat Sheet - SaltyCrane
Flow is a static type checker for JavaScript. This is a list of Flow types generated from the source code in https://github.com/facebook/flow/tree/v0.111.3/ The script to generate this list is on github. Fixes welcome. See also my TypeScript cheat sheet, TypeScript React cheat sheet, and Docker cheat sheet. There are separate sections for "private" or "magic" types with a $ in the name. See the no

Using Redux with Flow
Redux is a great library for managing applicationâ€™s state. But JavaScript is still a dynamically typed language, which comes with a lot of surprises at runtime. In this post Iâ€™ll show you how you can use Flow to embrace static type checking in your Redux-powered application. I choose to use Flow for the disjoint union support and the ability to convert the codebase incrementally. Read on to learn
