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

handmade-livereload-webpack-plugin

A Webpack plugin that allows pages to be automatically reloaded without the DevServer.

License: MIT Build Status env Known Vulnerabilities

This is a very simple Webpack plugin that allows to reload web pages while developing, without the need to set up the DevServer. This reduces configuration differences between production and development. It uses ws. It's a development only module.

How it works

This module is composed by 2 little components:

  • the webpack plugin itself, that every time the compiler done event is emitted, sends a ws event called RELOAD
  • a script, to be injected in the involved web pages, that is listening for the WebSocket message event with event.data === "RELOAD" and reacts reloading the page by doing window.location.reload()

Install

yarn add handmade-livereload-webpack-plugin -D

Usage

In the webpack configuration file, it must be first initialized with two mandatory keys port and host and one optional key delay (in milliseconds).

// webpack.config.js file
var HandmadeLiveReload = require("handmade-livereload-webpack-plugin")({
    port: 1234,
    host: "localhost",
    delay: 100 // emit the RELOAD event 100 ms after the webpack `done` hook
});

The handmade-livereload instance in an object with 2 keys:

  1. the plugin key is the plugin itself that can be added to the webpack plugins (if not production):

    // webpack.config.js file
    const IS_PROD = process.env.NODE_ENV === 'production' ? true : false;
       
    if (!IS_PROD) {
       plugins.push(new HandmadeLiveReload.plugin());
    }
  2. the path_to_client keys is just a string with the absolute path to the js source file that can be added to the webpack entries in order to be compiled:

    // webpack.config.js file
    if (!IS_PROD) {
      entry: {
        "handmade_live_reload": HandmadeLiveReload.path_to_client
      }
    }

    The handmade_live_reload.js compiled script have to be added to the involved web pages; using the HTML Webpack Plugin:

    // webpack.config.js file
    new HtmlWebpackPlugin({
       chunks: ['app', 'handmade_live_reload']
    })
