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 🙏

redux-execute Maintainability Build Status Coverage Status

Readme

Installation

Note: redux-execute requires redux@^4.0.0

npm install --save redux-execute

ES modules:

import { createExecue } from "redux-execute"

CommonJS:

const { createExecue } = require("redux-execute")

Why do I need this?

Please, read introduction to thunks in Redux. Execue just another way to run and test thunks(effects).

Motivation

Redux Execue middleware allows you to write "action creators" that return function instead of an action. These action creators are called effects. The effect can be used to delay the dispatch an action, or to dispatch another effect, or to dispatch only if a certain condition is met. The inner function receives the store methods dispatch and getState as parameters.

An action creator that returns a function to perform asynchronous dispatch:

const setValue = (value) => ({
  type: "SET_VALUE",
  payload: { value },
})

const setValueWithDelay = (value) => (dispatch) => {
  setTimeout(() => {
    // classic dispatch action
    dispatch(setValue(value))
  }, 1000)
}

Effect that dispatch another effect:

const incrementWithDelay = () => (dispatch, getState) => {
  const { value } = getState()

  // Just pass effect and all arguments as arguments of dispatch
  dispatch(setValueWithDelay, value + 1)
}

What is an effect?

An effect is a thunk that called by dispatch.

const effect = (a, b) => (dispatch, getState) => {
  return a + b
}

store.dispatch(effect, 1, 2) // 3

Composition

Any return value from the inner function of effect will be available as the return value of dispatch itself. This is convenient for orchestrating an asynchronous control flow with effects dispatching each other and returning Promises to wait for each other's completion.

const requestGet = (url) => () =>
  fetch(`/api${url}`).then((response) => response.json())

const userPostsFetch = (userId) => async (dispatch) => {
  const user = await dispatch(requestGet, `/users/${userId}`)

  if (user.isActive) {
    return dispatch(requestGet, `/users/${userId}/posts`)
  }

  return []
}

Logger

Redux Execue has logger out of the box. You can combine it with redux-logger:

import { createStore, applyMiddleware } from "redux"
import { createLogger } from "redux-logger"
import { createExecue } from "redux-execute"

import { rootReducer } from "./reducers"

const store = createStore(
  rootReducer,
  applyMiddleware(
    createExecue({ log: true }),
    createLogger({ collapsed: true }),
  ),
)
