choo-shortcut

Shortcut access to parts of the state anywhere in your app.

Useful to simulate "contexts", avoid passing down the state to hell. It's again a ridiculous little function.

Installation

npm i choo-shortcut

Example

// flowers-context.js
var createShortcut = require('choo-shortcut')

var shortcut = createShortcut(function (state, emitter) {
  return state.flowers
})

module.exports = shortcut.set
module.exports.getFlowers = shortcut.get

In your main file:

app.use(require('./flowers-context'))

Then anywhere in your app

var { getFlowers } = require('../flowers-context')

getFlowers()
// state.flowers that has been set somewhere

API

shortcut = createShortcut(reducer(state, emitter))

Creates a new shortcut (context store). reducer is a function which "reduces" the state to the part that should be stored. It gets the typical state and emitter of a Choo store.

shortcut.set(state, emitter)

The store that should be passed to app.use.

shortcut.get()

Returns the current value that's stored.
