React Lifecycle Hooks

A Simple abstraction to useEffect and make the lifecycle using hooks more declarative

Motivation

I was coding with some newbie developers, and when i started with the new team i realized that people are getting stuck using the react lifecycle with the useEffect hook, so i replicated the methods using the useEffect hook.

Documentation

Use Update

The useUnmount hook replicates the same functionality as the componentDidUpdate heres an example bellow

import React from 'react';
import { useUpdate } from 'react-lifecycle-hooks';

interface Props {
  // your prop interface fields goes here...
}

const App = (props: Props) => {
  useUpdate((prevProps, nextProps) => {
    // place here the code for the update on the component
  }, props);
};

Params:

 - `fn`: () => Promise<void> | void

 - `props`: Receives a generic called props `<T extends Record<string, any>>`

Use Unmount

The useUnmount hook replicates the same functionality as the componentWillUnmount heres an example bellow

import React from 'react';
import { useUnmount } from 'react-lifecycle-hooks';

const App = () => {
  useUnmount(async () => {
    // place your code bellow
  });
};

Params:

 - `fn`: () => void

Use Mount

The useMount hook replicates the same functionality as the componentDidMount heres an example bellow

import React from 'react';
import { useMount } from 'react-lifecycle-hooks';

const App = () => {
  useMount(async () => {
    // place your code bellow
  });
};

Params:

 - `fn`: () => Promise<void> | void

Use Previous

This is a helper that i've created to replicate the componentDidUpdate that gets the last value for that property. i think that will be very useful for you also

import React, { useState } from 'react';
import { usePrevious } from 'react-lifecycle-hooks';

const App = () => {
  const [value] = useState('');

  const previousValue = usePrevious(value) || '';
};

Params:

- `value`: Its a Generic Type for the `value` it already infers the type

Returns:

The return will be undefined or the infered value (the type of the variable that you are passing as a parameter).
