Testing | Recoil
Testing Recoil state inside of a React componentIt can be helpful to test Recoil state when testing a component. You can compare the new state against expected values using this pattern. It uses a React functional component, useRecoilValue and useEffect, to observe an atom/selector's changes and execute a callback every time the user performs an action that modifies the state. export const Recoil
Atom Effects | Recoil
Atom effects are an API for managing side-effects and synchronizing or initializing Recoil atoms. They have a variety of useful applications such as state persistence, state synchronization, managing history, logging, &c. They are similar to React effects, but are defined as part of the atom definition, so each atom can specify and compose their own policies. Also check out the recoil-sync library
Asynchronous Data Queries | Recoil
Recoil provides a way to map state and derived state to React components via a data-flow graph. What's really powerful is that the functions in the graph can also be asynchronous. This makes it easy to use asynchronous functions in synchronous React component render functions. Recoil allows you to seamlessly mix synchronous and asynchronous functions in your data-flow graph of selectors. Simply re
Getting Started | Recoil
Create React AppRecoil is a state management library for React, so you need to have React installed and running to use Recoil. The easiest and recommended way for bootstrapping a React application is to use Create React App: npx is a package runner tool that comes with npm 5.2+ and higher, see instructions for older npm versions. For more ways to install Create React App, see the official documen
Recoil
Minimal and ReactishRecoil works and thinks like React. Add some to your app and get fast and flexible shared state. Data-Flow GraphDerived data and asynchronous queries are tamed with pure functions and efficient subscriptions. Cross-App ObservationImplement persistence, routing, time-travel debugging, or undo by observing all state changes across your app, without impairing code-splitting.
