liquorstore

A reactive store that is fine, really. It works with React.

Development

yarn

yarn dev

Installation

npm i liquorstore

or

yarn add liquorstore

Usage

Create your state with the LiquorStore constructor.

import { LiquorStore } from "liquorstore"

const store = new LiquorStore({
  name: "Steve",
  age: 93,
  settings: {
    theme: "dark",
  },
})

Tip: The LiquorStore constructor takes a generic type for the initial state, in case the full type cannot be inferred from the initial value.

Next, subscribe to the store's changes via its hooks.

const App = () => {
  const { name, age, settings } = store.useStore()

  return (
    <div>
      <h1>{name}</h1>
      <h2>{age}</h2>
      <h3>{settings.theme}</h3>
    </div>
  )
}

There are a few hooks you can use:

• useStore - Subscribe to any and all changes in the store.
• usePath - Subscribe to a specific path in the state.
• useSelector - Use a selector function to select out just the state that you need.
• useStaticSelector - Like useSelector but you don't really have to memoize the selector function.
• useCanUndo - Subscribe to whether the store can undo or not.
• useCanRedo - Subscribe to whether the store can redo or not.
• useIsPaused - Subscribe to whether the store is paused.

store.mutate(state => void)

You can update the state using store.mutate().

store.mutate((state) => {
  state.name = "Steve"
  state.age = 94
  state.settings.theme = "light"
})

store.undo()

You can undo changes with store.undo(). If the store's history was paused then it will resume when store.undo() is called.

// store.current.age = 93
store.mutate((state) => (state.age = 94))
// store.current.age = 94
store.undo()
// store.current.age = 93

store.redo()

You can redo changes with store.redo(). If the store's history was paused then it will resume when store.redo() is called.

store.mutate((state) => (state.age = 94))
store.undo()
store.redo()
// store.current.age = 94

store.pause()

You can pause the store's history with store.pause(). Changes that occur while paused still effect the state and cause updates, however they do not create entries in the undo / redo stack.

store.mutate((state) => (state.age = 94))
store.pause()
store.mutate((state) => (state.age = 95))
store.mutate((state) => (state.age = 96))
store.mutate((state) => (state.age = 97))
store.undo()
// store.current.age = 94

store.resume()

You can resume the store's history with store.resume(). If the state has changed while paused, this will create a new entry in the undo / redo stack.

store.mutate((state) => (state.age = 94))
store.pause()
store.mutate((state) => (state.age = 95))
store.mutate((state) => (state.age = 96))
store.resume()
store.mutate((state) => (state.age = 97))
store.undo()
// store.current.age = 96
store.redo()
// store.current.age = 97
