Out of necessity and curiosity, I have created the smallest possible implementation of Redux which comes in at only 95 bytes (minified).

I frequently have needed a stripped down bare bones Redux without all those bells and whistles.

Redux itself is already a pretty small library at 1.6k (gzipped) but I was really looking for something that only had the weight of a single function. Thus Pico Redux was born.

The core Redux functionality itself is very minimal. This is all you need to recreatecreateStore:

constcreateStore=(reducer,state=reducer(void0,{type:'@@init'}))=>({dispatch:action=>(state=reducer(state,action),action),getState:()=>state})

I typically don't need middleware (unless I am in React-land). I also rarely need the subscribe functionality. Just the basic store is usually good enough.

But because I do occasionally use these features, I created Pico Redux with a modular design so these features can still be added... but only when necessary so you only pay (in bytes) for what you use.

// basic storeconststore=createStore(reducer)// store with subscribeconststore=withSubscribe(createStore)(reducer)// store with middlewareconststore=withMiddleware(createStore)(reducer)// kitchen sinkconststore=withMiddleware(withSubscribe(createStore))(reducer)

The interface is kept the same as Redux so you should already be familiar with how to use it:

import{createStore}from'pico-redux'constinit=0constreducer=(state=init,{type,value})=>type==='INC'?state+value:stateconststore=createStore(reducer)store.dispatch({type:'INC',value:100})store.getState()//=> 100

Try it out, give it a spin, let me know what you think!
