hyperapp-devtools

Developer tools for Hyperapp projects.
These tools have been extracted from hyperstart's debugger.

This is an higher order application (HOA) that records every action and allow the user to see input argument, output and state at every step.

See it in action here:

Installation

Install it from npm:

npm install hyperapp-devtools --save-dev

Or get it directly from unpkg:

<script src="https://unpkg.com/hyperapp-devtools"></script>

Usage

Just wrap your hyperapp:

import { h, app } from "hyperapp"
import devtools from "hyperapp-devtools"

const state = {
  count: 0
}

const actions = {
  down: value => state => ({ count: state.count - value }),
  up: value => state => ({ count: state.count + value })
}

const view = (state, actions) => (
  <div>
    <h1>{state.count}</h1>
    <button onclick={() => actions.down(1)}>-</button>
    <button onclick={() => actions.up(1)}>+</button>
  </div>
)

devtools(app)(state, actions, view, document.body)

Possible improvements

• set the app state when time traveling
• edit the app state
• trigger actions
