🧐   Why?

Forget about actions, connections, reducers and a lot of boilerplate to create and manage states. With reworm you can create and manage state as simple as on the image above.

Todo List Example

💻   Install and Usage

Install reworm using your package manager

$ yarn add reworm

Then just create your new state and use it!

import React from 'react'
import { create } from 'reworm'

const { get } = create({ name: 'John' })

const App = () => (
  <div>{get(s => s.name)}</div>
)

Change your state easily

Instead of defining actions or something else to change your state, with reworm you just need to use the set method like that:

import React from 'react'
import { create } from 'reworm'

const { set, get } = create({ name: 'John' })

class App extends React.Component {
  componentDidMount() {
    set(prev => ({ name: 'Peter' + prev.name }))
  }
  render() {
    return (
      <div>{get(s => s.name)}</div>
    )
  }
}

Using selectors

Selectors are good because they prevent you from duplicating code. With it you can just create some functions and use them throughout your application.

import React from 'react'
import { create } from 'reworm'

const { select } = create({ list: ['Peter', 'John'] })

const johnSelector = select(state =>
  state.list.find(user => user.includes('John'))
)

const App = () => (
  <div>{johnSelector(user => user)}</div>
)

🔎   API

create<T>(initial?: T): State

Create a new state

get((state: T) => React.ReactNode)

Use this method to access your state

set((state: T | (prevState: T) => T) => T)

Use this method to set your state

select<S = any>(selector: (state: T) => S) => (fn: GetFn<T>) => React.ReactNode

Create selectors that can be used with your state and avoid repeating code.

import React from 'react'
import { create } from 'reworm'

const { select } = create({ name: 'John' })
const userSelector = select(s => s.name)

const App = () => (
  <div>{userSelector(name => name)}</div>
)

📝   Typings

interface ProviderProps<T> {
  initial?: T
}

type PrevState<T> = (prevState: T) => T
type GetFn<T> = (state: T) => React.ReactNode

interface State<T> {
  get: (fn: GetFn<T>) => React.ReactNode
  set: (param: T | PrevState<T>) => void
  select: <S = any>(selector: (state: T) => S) => (fn: GetFn<S>) => React.ReactNode
}

function create<T>(initial: T) => State<T>
