CooperTS

CooperTS is an opinionated ecosystem for building web apps with React Typescript.

Not a Framework

CooperTS is a collection of libraries, design patterns, and strongly-held opinions that we think make building web apps fun, easy, and a joy to maintain.

Eventually CooperTS will include tooling to help you implement some of the design patterns quickly.

Opinions

• Null is not a good representation of nothing.
• JSON from API endpoints should be validated against our expectations as it is decoded
• Side effects should be implemented as reactions
• Typechecking is preferable to writing tests to validate types
• It should be impossible to enter into an invalid state

Design Patterns

• Finite State Machines
• Decoders
• Reactions
• Stores
• Error handling
• API calls
• API data design (based on HATEOAS)

Libraries We Use

• CreateReactAppTypescript
• Mobx
• Jsonous
• Maybeasy
• Ajaxian
