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

react-compose-onmount

Build Status npm version

A helper function to attach onmount handler to stateless function components.

Background

If you prefer to write a React components as a function like the following, you tend to avoid using class-based components.

const Hello = ({ name }) => (<div>Hello, {name}!</div>);

Function components lack local state, lifecycle methods, and so on. Local state is sometimes important to keep UI state, for example, a string in a text field while typing, which shouldn't be put in global state. For the local state, react-compose-state should help. Another case is when you want to do something when a component appears. For example, you might need to fetch data from network. With class-based components, you can use the componentDidMount lifecycle method. This package is for the specific case when you want to only attach componentDidMount handler to a stateless function component.

Install

npm install react-compose-onmount --save

Usage

Basic usage:

import React from 'react';
import { composeWithOnMount } from 'react-compose-onmount';

const onMount = () => window.alert('mount!');

const SomePage = composeWithOnMount(onMount)(() => (
  <div>
    <h1>Some Page</h1>
  </div>
));

With unmount:

const onMount = () => window.alert('mount!');
const onUnmount = () => window.alert('unmount!');

const SomePage = composeWithOnMount(onMount, onUnmount)(() => (
  <div>
    <h1>Some Page</h1>
  </div>
));

With options:

const onMount = () => window.alert('mount!');
const onUnmount = () => window.alert('unmount!');
const options = {
  onMount: 'componentWillMount',
  onUnmount: 'componentDidUnmount',
};

const SomePage = composeWithOnMount(onMount, onUnmount, options)(() => (
  <div>
    <h1>Some Page</h1>
  </div>
));

Example

The example folder contains a working example. You can run it with

PORT=8080 npm run example

and open http://localhost:8080 in your web browser.
