simple functions for creating complex apps 

[![Build Status](https://travis-ci.org/jokio/jokio.svg?branch=master)](https://travis-ci.org/jokio/jokio)
[![npm version](https://badge.fury.io/js/jokio.svg)](https://badge.fury.io/js/jokio)


## Quick Start:
just run:
```bash
yarn create jokio-app myapp
```
for detailed information and all options please visit [create-jokio-app](https://github.com/jokio/create-jokio-app) repository.


## Idea:
In every process we need three different objects:
* Props
* State
* Context

jokio provides following structure to describe processes and make it composable
```ts
type Process = (props: Props) => (state: State, context: Context) => Promise<State>

const process1: Process
const process2: Process

const run = compose(
  process1,
  process2,
)

run(initialState, initialContext)
```


## Functions:
- compose
- run
- runWith
- log
- timer
- pubsub
- uniqueId


## Example:
```js
import { compose, log } from 'jokio'

const process1 = (props) => (state, context) => {
  return { ...state, info: state.info + ' hello' }
}

const process2 = (props) => (state, context) => {
  return Promise.resolve({ ...state, info: state.info + ' world' })
}

const initialState = {
  info: '[Cool App]'
}

const run = compose(
  process1({}),
  process2({}),
  log(),
)

run(initialState)

```
