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 🙏

DevTools Ignore Webpack Plugin

A Webpack plugin to ignore-listing code in Chrome devtools. To see how ignore-listing helps your development experience, check out this offical demo. This plugin is based on the plugin implemented in Angular CLI project.

Note: This plugin is only for Webpack 5.

Installation

npm install --save-dev devtools-ignore-webpack-plugin

Usage

First, follow webpack's guide to enable source maps in your project. Please note that the "inline" source map options are not supported yet.

Then, add the plugin to your webpack config:

const DevToolsIgnorePlugin = require("devtools-ignore-webpack-plugin");

module.exports = {
  // ...,
  plugins: [new DevToolsIgnorePlugin()],
};

Options

Currently, this plugin supports two options: shouldIgnorePath and isSourceMapAsset.

shouldIgnorePath

shouldIgnorePath is a function that checks whether a source file should be ignored. The function takes a single argument, which is the path of the file. It should return a boolean value.

new DevToolsIgnorePlugin({
  shouldIgnorePath: function (path) {
    if (path.includes("my-lib")) {
      return false;
    }
    return path.includes("/node_modules/") || path.includes("/webpack/");
  },
});

When not specified, the default function is:

function defaultShouldIgnorePath(path) {
  return path.includes("/node_modules/") || path.includes("/webpack/");
}

isSourceMapAsset

isSourceMapAsset is a function that checks whether a map file is potentially a source map asset. The function takes a single argument, which is the name of the potential source map asset. It should return a boolean value.

Note: This should rarely be needed. Known scenarios include only looking at .js.map in rare scenarios where you have other files that end in .map

new DevToolsIgnorePlugin({
  isSourceMapAsset: function (name) {
    return name.endsWith(".js.map"); // if you have other files that end in .map
  },
});

When not specified, the default function is:

function defaultisSourceMapAsset(name) {
  return name.endsWith(".map");
}
