Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

async-redux-generators

Generators for async RSA-compliant actions, and corresponding reducers. Generates three actions and three reducers for REQUESTED, RECEIVED, and FAILED state. Generators assume RESTful API and generates with certain conventions.

Reducer will activate loading and error states under camelCase names such as fetchAlbumLoading and fetchAlbumError. The entire store will also have loading state activated, see below for example.

Install

npm install --save async-redux-generators

Usage

import { createStore, applyMiddleware, compose } from 'redux';
import thunk from 'redux-thunk';

// fetchJSON is a wrapper around standard fetch that formats response and header/body to JSON
// Contains actions get, post, put, patch, and delete
import { asyncAction, fetchJSON, asyncReducer, asyncGenerators } from 'async-redux-generators';

// asyncAction(actionName, url, fetchFunction)
const fetchAlbumAction = asyncAction('FETCH_ALBUM', 'http://localhost:5000/albums', fetchJSON.get);
// asyncReducer(actionName)
const albumReducer = asyncReducer('FETCH_ALBUM');
// OR
// asyncGenerators(actionName, url, fetchFunction)
const { fetchAlbumAction, albumReducer } = asyncGenerators(
  'FETCH_ALBUM',
  'http://localhost:5000/albums',
  fetchJSON.get
)

const store = createStore(
  albumReducer,
  compose(
    applyMiddleware(thunk)
  )
);

// generatedAsyncAction(metaData)
fetchAlbumAction({ id: 5 });// If id is provided in metaData, it will be appended to the url (url/id)

// Dispatch FETCH_ALBUM_REQUESTED
// Runs async function to fetch album
// store.loading = true
// store.fetchAlbumLoading = true

// Done fetching
// Dispatch FETCH_ALBUM_RECEIVED
// store.loading = false
// store.fetchAlbumLoading = false
// album with id of 5 will appear in the store

// Error Occurs
// Dispatch FETCH_ALBUM_FAILED
// store.loading = false
// store.fetchAlbumLoading = false
// store.fetchAlbumError = Error Object
