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 🙏

About dyna-ts-module-boilerplate

Boilerplate with Webpack setup for ES6/ESNEXT for React TypeScript Component Libraries/Packages.

  • Develop in TypeScript
  • Debug with Chrome Dev Tools
  • Write tests with Jest
  • Lint
  • Build
  • Deploy on Git and npm

This boilerplate includes minimal configuration and dependencies for creating one or multiple modules written in TypeScript.

It can export one module or multiple for explicit imports.

Happy coding!

Not react, just Web or Node library?

This boilerplate is designed for developing React components. However, if you need a lighter boilerplate for node utils, or web utils without react, you can use the the dyna-ts-module-boilerplate, which is a similar boilerplate but lighter.

Again this supports React and JSX but hasn't StoryBook, react ESList etc.

How to use this boilerplate

To use it and create your own module:

  • Clone it into a folder named after your module, like my-module.
  • Run pnpm bootstrap to unlink it from this git repo.

Example:

git clone https://github.com/aneldev/dyna-ts-react-module-boilerplate.git my-module
cd my-module
pnpm bootstrap

Your repo will now be ready, and you can git init under your own account.

Why is create-react-app different?

It is different because create-react-app creates React applications and includes everything an application needs.

The dyna-ts-react-module-boilerplate creates React modules (reusable components). It creates React components that will be used in React applications or other modules.

Features

  • Uses the powerful pnpm as a packager, but you can easily replace it with another one
  • Written in TypeScript, .tsx, .ts
  • Supports CSS, SCSS & LESS at the same time
  • Advanced ESLint
  • Tested with Jest
  • Debugged with Chrome Dev Tools
  • Distributes with TypeScript definitions
  • Supports distribution of one or multiple modules for explicit import
  • Supports distribution of modules for Web and Node
  • Analyzes the distribution
  • Exports ESNext modules
  • Exports Typescript declarations
  • Detects circular dependencies (which can lead to undefined or null imports)
  • Monorepo friendly

Specs

  • Webpack 5
  • TypeScript v5 with higher restrictions
  • Supports ES2019 lib
  • React JSX syntax
  • Less/Scss module CSS or other loaders
  • Image loaders
  • ESLint configuration for React and rules
  • Webpack analyzer for package content with the webpack-bundle-analyzer

Scripts

| Script | Description | Notes | |:------------------------|:-------------------------------------------------------------------------------------------------------------|:------------------------------------------------------------------| | install-clean | Clears all node_modules and runs pnpm install | | | storybook-start | Starts Storybook | | | storybook-deploy | Builds Storybook for publishing to Git | | | build | Builds .src/index into the dist folder | | | build-watch | Runs build in watch mode | | | build-analyze | Shows the Webpack dependencies analyzer | | | commit | Easily commit, including unstaged files | | | commit-amend | Easily amend the previous commit with unstaged files | | | lint | Runs ESLint on your source code | | | lint-watch | Runs ESLint in watch mode | | | lint-fix | Autofixes issues with ESLint | | | lint-fix-watch | Autofixes issues with ESLint in watch mode | | | test | Runs all or filtered tests | Arguments <filter>.

If you see the bootstrap script and you've already run git init on your versioning system, you can delete:

  • The bootstrap script
  • The bootstrap.js file

Configuration

This is a Zero-Configuration boilerplate!

However, if needed, you should only edit the following:

Webpack Loaders/Rules

Add them in /webpack.loaders.js.

Webpack Plugins

Add them in /webpack.plugins.js.

Distributions

This boilerplate can export one or multiple independent modules.

Single module

If the boilerplate finds the src/index.ts file, it considers the module Single.

For example:

Content of src/index.ts:

export class Invoice {...}

From another package, you can import this module like this:

import { Invoice } from "my-module";

Multi modules

If the boilerplate cannot find the src/index.ts file, it considers the module Multi. In this case, the /src folder should contain folders, each representing a module with its own index.ts file.

This allows making explicit imports from other packages or apps improving the tree shaking.

For example:

Folder structure:

src/Invoice/index.ts   // content: export class Invoice {...}
src/Person/index.ts    // content: export class Person {...}

From another package, you can explicit import these modules like this:

import { Invoice } from "my-module/dist/Invoice";
import { Person } from "my-module/dist/Person";

Similarly, you can distribute modules for specific environments, such as Web or Node, ensuring you import dependencies compatible with the target environment.

The dist folder contains only JavaScript code (ES5), without Webpack module loaders, so the code works everywhere as ES5.

Switching from Single to Multi

  1. The /src folder should contain only subfolders.
  2. Each subfolder is considered an independent module.
  3. Each subfolder should have an /index.ts that exports what’s needed.
  4. Delete the src/index.ts.

Switching from Multi to Single

  1. Create the src/index.ts.
  2. Export what’s needed.
  3. The folder structure can be anything.

Develop

Development is based on Jest tests. After creating something in the src, create a Jest test like the main.test.ts and run or debug it.

Steps:

  1. Write your Jest tests anywhere under the ./src.
  2. Important Place a debugger; statement somewhere; otherwise, the debug runtime won’t stop.
  3. Run pnpm test-debug <name of the test file>.
  4. Open chrome://inspect/#devices.
  5. Select the remote target instance and click inspect.
  6. Ready for debugging.

Note: You might need to press Resume script (the Play button) to skip some internal Node lib points.

For more information about the tests, read below.

Analyze

  1. Run pnpm analyse.

Test

Write tests

For testing, Jest is used. Check the documentation for details.

Test files can be located anywhere but should have names in the format *.(test|spec).(ts|js).

Run tests

Run pnpm test to execute your tests and coverage.

Run pnpm test-watch to execute tests on changes.

Run pnpm test-no-coverage to run tests without coverage.

Run pnpm test-update-snapshots to update the snapshots.

Run pnpm test-debug to debug with Chrome Dev Tools.

Dist / Release

General

Run pnpm build to create a distributable version of your project in the dist/ folder.

The package configuration exports the dist/ folder, so you need to run pnpm build each time you want to publish this package. TypeScript declarations are included out of the box.

Run pnpm release to build, publish to npm, and push to your repo.
