React Hooks(三):Redux-React-Hook
React Hooks確實簡化了連接React及Redux之間的代碼,而React Hooks本質較為接近函數式思維(functional thinking),也令要寫好單元測試更為簡單。當然,如上面所言,Redux-React-Hooks尚未成為正式專案,大家可以密切留意,看看是否會成為未來標準連接React及Redux的部件。

render: This is the function component body itself.
componentDidMount, componentDidUpdate, componentWillUnmount: The useEffect can express all combinations of these.
shouldComponentUpdate: React.memo
constructor: Function components don’t need a constructor. You can initialise the state in the useState call. If computing it is expensive, you can pass a function to useState.
Some important Rules
Only call Hooks at the top level. Don’t try to call Hooks inside loops, conditions, or nested functions.
Only call Hooks from React function components. Don’t try to call Hooks from regular JavaScript functions.

Improving your mental model of useEffect
The API of useEffect:
Accepts a function
If it returns a function, it will do cleanup when the component is unmounted
Has an optional 2nd argument to pass in the data it depends on
If we leave it blank — it will run on every single render.
If we pass in an empty array — it will execute only when the component mounts, and not on any updates
If we pass in a value — it will execute when any of those values change
If you are using the react-hooks eslint plugin (and you should) — not providing the dependencies to your useEffect will give you warnings.

useMemo Hook
Should You Really Use useMemo in React? Let’s Find Out.
It is worth noting that the initial renders with useMemo take quite a setback in terms of performance. We expected an initial performance loss of around 5–10% consistently, but have found that this highly depends on the data/processing complexity and can even cause 500% performance losses, which is 100x more performance loss than expected.
How to Use the `useMemo` Hook in React to Build Efficient Components
React.useMemo and when you should use it
What problem does useMemo solve?
useMemo is a React hook that memorizes the output of a function. That is it. useMemo accepts two arguments: a function and a list of dependencies. useMemo will call the function and return its return value. Then, every time you call useMemo again, it will first check if any dependencies have changed. If not, it will return the cached return value, not calling the function. If they have changed, useMemo will call the provided function again and repeat the process.
When should you use it?
The easiest way to do it is to write code without useMemo first, then add as needed.
But do not overuse it
The overhead
No guarantees
Bonus: useCallback
useCallback is pretty much the same as useMemo, but for functions.

useFetch
The useFetch hook can be used to implement fetch in a declarative way.
useInterval
If you want to implement setInterval in a declarative manner you can use this hook called useInterval.
useComponentDidMount
This hook is a small example of how to execute a callback right after a component is mounted.
useComponentWillUnmount
useComponentWillUnmount is similar to the example above but will execute a callback as soon as the component is unmounted.

You can only use hooks in React Function Components, and in Custom Hooks.
There aren’t hook primitives for componentDidCatch or getSnapshotBeforeUpdate.

Yellow hooks provide useful performance optimizations by using memoization. Managing lifecycle and inputs should be done with caution.
useCallback
useMemo
Red hooks interact with mutable world using side effects. They are most powerful and should be used with extreme caution. Customs hooks are recommended for all non-trivial use-cases.
useRef
useEffect
useLayoutEffect
Obey Rules of Hooks.
Don’t do any side-effects in main render function.
Unsubscribe/dispose/destroy all used resources.
Prefer useReducer or functional updates for useState to prevent reading and writing same value in a hook.
Don’t use mutable variables inside render function, use useRef instead.
If what you save in useRef has smaller lifecycle than the component itself, don’t forget to unset the value when disposing the resource.
Be cautions with infinite recursion and resource starvation.
Memoize functions and objects when needed to improve performance.
Correctly capture input dependencies (undefined => every render, [a, b] => when a or b change, [] => only once).
Use customs hooks for non-trivial use-cases.
Testing Effects
Substituting useEffect with useLayoutEffect gets the tests to pass.

Observer
An Observer will attach itself to the Subject and wait patiently.
When the Subject changes, it will go notify all the observers with the latest data.
Provider
The way it works is that a Provider sets some values on a Context object that is set on a parent level of the component tree.
Any of the child components , called Consumers, can then grab those values from the context directly, instead of having to pass the values through the props of each of the children.

Redux
With the useState hook, the business logic responsible for computing the new state would have to be inside all the components that would update the state.
With useReducer we can have all the business logic in one place (the reducer itself), making it easy to maintain and keeping the components focused on what they were primarily designed to do.
The useReducer hook keeps the “dispatching an action to update the state” pattern that’s used by Flux, Redux, Vuex and other state management solutions.

Suspense
When to use React Suspense vs React Hooks
React Suspense is to a Monad as Hooks are to Applicative Notation
Effectful.JS is a transpiler for embedding effectful into JavaScipt. It supports both Monadic and Applicative targets. It greatly simplifies programs in the designing, implementing, testing, and maintaining stages.
Hooks and Suspense- React’s Class Warfare
“Suspense” gives React developers the ability to suspend the rendering of a component while it’s waiting for the resolution of other a-synchronous operations.
“Concurrent Rendering,” similarly with “Suspense,” can pause expensive rendering processes to make high priority DOM updates first. It can be used in combination with “Suspense” to improve user experience by “skipping unnecessary loading states on fast connections.”
“Hooks” allow function components to use state and lifecycle features.
