Thistate is a library to manage global states with custom React hooks.

Documentation

To use thistate follow the documentation to the some methods.

Thistate.useState

Returns a statefull value and function to update it.

function useState<StateType>(initializer)

initializer - Is a key or an observable state.

Thistate.create

Create an state entry on the store.

function create<StateType>({ key, defaultValue }): StateListener<StateType>

key - Is the key of the state.
defaultValue - Is the initial value of the state.

How to use

First of all it is necessary to install the lib in your project with the following lines.

If you using npm

npm i thistate

If you using yarn

yarn add thistate

To use thistate is really simple, just use 2 functions, create and useState (from thistate import both).

First you should create a new state, for example:

const myStateListener = create({
  key: 'myState',
  defaultValue: 'myInitialValue'
})

Once created you can use the state anywhere in the application passing the state key. For example:

const [user, setUser] = useState('myState')

Or a StateListener returned from the create function.

const [user, setUser] = useState(myStateListener)

Code examples

Take this simple example.

import * as Thistate from 'thistate'

const nameState = Thistate.create({
  key: 'name',
  defaultValue: ''
})

function App() {
  return <>
    <Display listen={nameState} />
    <Input key='name' />
  </>
}

function Input({ key }) {
  const [value, setValue] = Thistate.useState(key)
  return <input onChange={evt => setValue(evt.target.value)} value={value} />
}

function Display({ listen }) {
  const [value] = Thistate.useState(listen)
  return <h2>{value}</h2>
}
