React-PWA - `v2` is here 🚀🎉⚡️

Starter kit for modern web applications!

Synopsis

This project (a GitHub template) is an opinionated setup for modern web applications. It's a combination of essential (and minimal) libraries/components/utils/etc., which developers usually need during the process of making modern React applications.

Motivation

Almost all projects need to have a router, a UI framework, store integration, theming, error handling, base file/folder structure, a builder, some developer tools (eslint, prettier, etc), and many more. In this starter kit, we tried to put together the best options available from the above-mentioned fields. Out of the box, it provides a modern production-ready setup created by developers for developers 💚

Vite

Vite is a blazingly fast build tool based on native ES modules, rollup, and esbuild. React-PWA v1 was based on CRA. We still love CRA and really think it's a great tool, but Vite provides a much better developer experience and it's unconditionally faster (maybe, we will also create a CRA version of React-PWA v2 in near future).

React

The latest version (v18) is used here. All dependencies support React v18 and the v2 is refactored according to the latest changes and requirements of React v18.

TypeScript

"Not using TypeScript is like driving without a seatbelt" - Matt Howard.

For those who are not familiar with TypeScript - don't worry, you will love it, as we all did. TypeScript is a superset of JavaScript; it should be very easy to work with if you know JavaScript.

Router

React Router v6 is used here. You can find routing in the src/routes folder.

UI-framework

MUI v5 is used here. MUI is a fully-loaded component library, super customizable, and easy to use.

Store

As a store management tool Recoil is used. Check the src/store folder for more information.

Notifications

Out of the box you have a notification system. To show a simple notification you can use useNotification hook:

import { useNotifications } from '@/store/notifications';

function MyCoolComponent() {
  const [notifications, actions] = useNotification();

  function showNotification() {
    actions.push({ message: 'Բարև, կարմի՛ր արև' });
  }

  return (
    ...
  );
}

Theme

The theme system is based on MUI Theme. To get the current theme mode or to change it you can use useTheme hook:

...
import { useTheme } from '@/store/theme';

function MyCoolComponent() {
  const [theme, actions] = useTheme();

  // check the current theme mode
  console.log(theme);

  // if you want to change the theme, call an appropriate action
  function toggleTheme() {
    actions.toggle();
  }

  ...
}

You have access to theme object via sx prop and styled-components:

import Box from '@mui/material/Box';
import Button from '@mui/material/Button';
import { styled } from '@mui/system';

// styled-components
const MyCoolButton = styled(Button)(({ theme }) => ({
  marginRight: theme.spacing(1),
  color: theme.palette.text.disabled,
}));

// sx prop
function MyCoolComponent() {
  return <Box sx={{ borderRadius: theme.shape.borderRadius }}>...</Box>;
}

Also, you can redefine the theme in the theme configuration file. Check the src/theme/themes.ts file for more information.

Base file/folder structure

Here how the base file/folder structure looks like:

TBD: more information about the file/folder structure will be added soon.

PWA

Out of the box, it's a Progressive Web Application. It can be installed on mobile and desktop devices 🙂, it can work offline, and many more. Check more about PWAs here

Your users will also be informed about the new version of your app:

Performance

After all these integrations the biggest bundle size is ~79KB. It means even the first load will be pretty fast (in my case it's 1.1s), further loads (already cached by service worker and workbox) will take ~0.25s.

NOTE: The performance is not 100 because it's running on demo server.

Hotkeys

A basic implementation of hotkeys is demonstrated here. Check the src/sections/HotKeys for more information.

Currently, you can use the following hotkeys:

Alt+s - to toggle the theme mode Alt+t - to toggle the sidebar Alt+/ - to open the hotkeys dialog

Error Handling

Nobody likes white screens and crashes without any notes. In src/error-handling you can find the error handling implementation. Here you can find withErrorHandler high order component. You can wrap any component by this HOC and it will catch all errors and show a default or your custom fallback. Currently, the main APP component is wrapped by withErrorHandler HOC.

Pages

From a layout point of view the application consists of 3 main parts:

Header
Sidebar
Pages

The last one is a router-based switcher. All routes are defined in src/routes. By default, pages are being loaded asynchronously via asyncComponentLoader. You can use it to asynchronously load any React component you want. It uses React.Suspense and React.lazy with some magic 🧙‍♂️

Dev tools

eslint

The latest version of eslint with the latest recommended collection of eslint rules is available out of the box. It contains:
- eslint:recommended
- react/recommended
- @typescript-eslint/recommended
Check the .eslintrc.json file for more information.
prettier

Stop fighting about styling in code reviews; save your time and energy - configure it once and let the machine format/correct your code.

Check the .prettierrc.json file for more information.

There is an additional configuration for your import statements. They will be automatically ordered and grouped by the given rules (check the .prettierrc.js) - one more topic for debates in code reviews :)
husky

You can use it to lint your commit messages, run tests, lint code, etc.

Currently, only pre-commit hook is set up. Every time you try to do a commit it will run prettier and eslint to be sure that everything is according to the rules.
lint-staged

lint-staged helps to run eslint and prettier only on staged files - it makes the linting process super fast and sensible.
https localhost

It's a simple way to run your application on localhost with https.

Just run:
```
npm run https-preview # or yarn https-preview
```
after:
```
npm run build # or yarn build
```
and check https://localhost in your browser.

NOTE: first time it will ask you about installing localhost certificate. For more info check this

Usage

You can use this template by just pressing Use this template.

Or you can fork/clone it.

Install dependencies:

npm install # or yarn

In order to run it in development, run:

npm run dev # or yarn dev

In order to do a production build, run:

npm run build # yarn build

There are two more scripts:

preview and https-preview

preview command will boot up local static web server that serves the files from dist folder. It's an easy way to check if the production build looks OK in your local environment.
https-preview is the same, but with HTTPS. It's handy for testing your PWA capabilities in your local environment.
