Preact modern startupper

This is minimalistic boilerplate repository which goal is to boost productivity of small / middle size real world web projects and make new apps highly optimised.

Current bundle size (gzipped) is 19.4 KB.

You: Why should I care:question::question:

• easy to use boilerplate generators for components and modules
• ready to use storybook support
• side effects handling - through unistore - additional middlewares are not needed
• store compatible with Redux DevTools
• localisation support - you can easily start developing multiple-language app
• pre-rendering support - you can render static HTML webpages out of app routes
• battle-tested project structure - used in real world apps like Passwords Fountain
• great code editors support (check Code editors support section to read more about recommended plugins)

If you can't stand that 19.4KB I have good news. If you remove existing example modules & boilerplate you can end up with ~ 11KB starter.

Not bad, right? 😎

Installing project dependencies

npm install

Development

Use npm start to run development server - it will be available at localhost:8080.

When developing component it is recommended to use Storybook (developing in isolation) instead of tinkering within actual app. To run storybook server use: npm run storybook. It should show up at localhost:6006.

To create new component or module always use built-in generator 🏭

npm run generate

Example component can be found in:

• src/common/Button

Example modules can be found in:

• src/modules/localisation
• src/modules/counter

What about utils?

We have place for them in src/common/utils. Check out src/common/utils/rendering.ts it may be helpful during conditional rendering ;)

During development don't forget to check files listed below:

• src/common/theme.ts - here we have all of our UI registries. This file helps a lot in maintaining app UI.
• src/@types - we define types here if they haven't been provided by library creator. Unfortunately, TypeScript is still not everywhere ;(
• plopfile.js - here you can see what is going to be generated after running npm run generate. All templates are inside plop-templates folder.
• src/modules/localisation/i18n.ts - want do add new language support? Note: by default all translations are bundled alongside your app code, but you can always change that :)
• webpack.config.js - bundler config. You shouldn't need to open it often, it's quite easy to go through it though.

Running unit tests

If you want to run tests only once, use npm test. You can also use test runner in watch mode by leveraging npm run test:watch.

Commiting changes

After running git commit husky pre-commit hook will trigger:

1. TypeScript compiler - checking types
2. Linters - checking if rules weren't violated (Eslint + Stylelint)
3. Unit tests (Jest)

When something goes wrong you will get an error in your terminal so you can react accordingly. After fixing all problems try committing your changes again.

Getting into production

You probably won't need to run that often, but this will generate production version of your Front-end:

npm run build

FAQ

What about Redux DevTools support? 📡

It's supported. Each module uses unistore which is connected to Redux DevTools. Install proper extension to make use of it: https://github.com/zalmoxisus/redux-devtools-extension

What about app profilling? 📈

Preact-devtools extension does support profilling, you can install it from here: https://github.com/preactjs/preact-devtools

What about caching? ♻️

There is simplest service worker setup via webpack OfflinePlugin - https://github.com/NekR/offline-plugin If you don't want to use it, but you want simple cache on Front-end api calls, then it's better to use appropriate libraries, check out: https://github.com/elbywan/wretch

What about eliminating duplicated requests, retrying them once fail...? 🏇

Beyond scope of this project but check out: https://github.com/elbywan/wretch-middlewares

What about lazy loading routes? ✂️

Beyond scope of this project, but it's recommended to use https://github.com/prateekbh/preact-async-route or lazy via https://github.com/preactjs/preact-compat.

What about normalizing data? 📝

Beyond scope of this project, it's recommended to use standard approaches though: https://github.com/paularmstrong/normalizr
