minimally

Minimal key-value store and event subscription

Inspired by https://github.com/developit/mitt/

• Microscopic: weighs about 200 bytes gzipped
• Functional: methods don't rely on this
• Great Name: somehow minimally wasn't taken

minimally was made for the browser, but works in any JavaScript runtime. It has no dependencies and supports IE9+.

Install

This project uses node and npm. Go check them out if you don't have them locally installed.

$ npm install --save minimally

Then with a module bundler like rollup or webpack, use as you would anything else:

// using ES6 modules
import minimally from 'minimally'

// using CommonJS modules
var minimally = require('minimally')

The UMD build is also available on unpkg:

<script src="https://unpkg.com/minimally/dist/minimally.umd.js"></script>

You can find the library on window.minimally.

Usage

import minimally from 'minimally'

const model = minimally()

// listen to an event
model.on('foo', e => console.log('foo', e) )

// Set value for key and dispatch event to subscribers
const val = { a: 'b' }
model.set('foo', val)

// Get value for key
m.get(key) === val

// working with handler references:
function onFoo() {}
model.on('foo', onFoo)   // listen
model.off('foo', onFoo)  // unlisten
