Installing effect packages | Effect with React 19: Project Template

We are now ready to install effect. We are going to install effect, @effect/schema and @effect/platform:

effect: core library that provides primitives to build applications with effect and schemas
@effect/platform: provides effect services for things like HTTP requests, file system, and more

pnpm add effect @effect/platform

At this point, we have the following dependencies installed:
