API
useDidMount(f)
Similar to componentDidMount in React class component.
Arguments
f: () => void: f is called when component did mount.
import { useDidMount } from 'react-hooks-lib'
const MyComponent = () => {
useDidMount(() => {
console.log('didMount')
})
}useWillUnmount(f)
Close to the componentWillUnmount in React class component.
Arguments
f: () => void: f is called when component will unmount.
import { useWillUnmount } from 'react-hooks-lib'
const MyComponent = () => {
useWillUnmount(() => {
console.log('willUnmount')
})
}useDidUpdate(f, options?)
Similar to componentDidUpdate, it only runs on updates.
Arguments
f: () => Function | void: f is called on every updates. LikeuseEffect, f can return a clean-up function.conditions?: Array<any>: Optional array for conditionally firing an effect, same as the second argument passed touseEffect.
import { useDidUpdate, useCounter } from 'react-hooks-lib'
const MyComponent = () => {
const { count, inc } = useCounter(0)
useDidUpdate(() => {
console.log('DidUpdate')
})
return (
<div>
{`count: ${count}`}
<button onClick={() => inc(1)}>+1</button>
</div>
)
}createContextState(initial?)
createGlobalState(initial?)
useMergeState(initial?)
Arguments
initial?: Object: Initial state object, default is{}.
Returns
state: Object: Current state object.set: ((Object) => Object) | Object: LikesetStatein React class component, merge the old and new state together.
import { useMergeState } from 'react-hooks-lib'
const MergeState = () => {
const { state, set } = useMergeState({ name: 'Victor', age: 1 })
return (
<div>
<h3>useMergeState</h3>
<div>
{`state: ${JSON.stringify(state)}`}
<button onClick={() => set(({ age }) => ({ age: age + 1 }))}>age+1</button>
</div>
</div>
)
}useNestedState
Arguments
initial?: Initial state, default isundefined.
Returns
state: Current state.get(pathString, defaultValue): Get value form state at a specificpathString. eg:get("a.b.c")/get("" | undefined), ifpathStringis empty,it will return the state object.set: (pathString, newValue | prevValue => newValue): Set value at a specificpathString. eg:set("a.b.c", prev => prev + 1)/set("" | undefined, {}). ifpathStringis empty,it will set the entire state object.
