React / React Native State Management.

Build a thorough understanding of state management in React/React Native Apps.

Prerequisite: You get most out of this workshop if you have a working experience with React (or React Native) as well as JavaScript/TypeScript.

This workshop may be held in the context of React (web-app) or React Native (mobile app).

Topics are covered interactively via

• 1
  live coding demos 🎓🖥 - in which I'll ask you many questions.
• 2
  coding exercises 💻 - in which you'll write and/or refactor code.

The following topics are possible - all or a subset of them may be covered in a workshop.

React itself offers tools for global state management.

Topics:

• Local reactive state with useState and useReducer hooks
• Lifting state up (method + issues)
• React Context: Global state management with context providers and consumers
• Custom hooks: Extract state management (i.e. business logic) into custom hooks

The simple, yet powerful third-party state management library zustand is gaining more and more traction.

Topics:

• Simple global state management with zustand which are optimized to reduce unncessary re-renders
• Analyze state changes with Redux Dev Tools.
• Custom hooks to select state from zustand stores

The main focus of the workshop lies on the most-widely used third-party state management library for React: Redux.

Topics:

• Understand the Redux life-cycle
• Vanilla Redux (define action types, action state, reducer function etc. manually)
• state selector functions
• Analyze state changes with Redux Dev Tools
• Custom hooks to select state from the Redux store
• redux-toolkit: The modern and recommended way of using Redux

  • state slices
  • asynchronous actions with Redux thunks
• redux-saga middleware: Sophisticated orchestration of asynchronous events

  • Effects: take, call, put, race, delay etc.
  • blocking vs. non-blocking effects
  • create non-blocking tasks with the fork effect
  • Saga helpers (takeEvery, takeLatest etc.)
  • Understand interaction between Redux saga middleware and Redux reducer
• redux-persist: Persist state (or sub-states) for offline usage of your app
