Directory Structure

src

├── pages       # all top level pages (Redux tree will be connected to these)
└── utils       # any utility functions/classes

CSS

• Try not to use scss or sass.

• Create a separate css file for each react component and place them in the same directory. Eg.

  components
  ├── ...
  ├── my-component.js
  └── my-component.css
  

• Try to use locally scoped css for components. Locally scoped css rules won't affect anything other than the markup inside the component.

• To make a css file locally scoped, use the format *.modules.css for the file name. Eg.

  components
  ├── ...
  ├── my-component.js
  └── my-component.module.css # css rules will be locally scoped for my-component.js
  

• Import css directly into your component files and let webpack do the work.

  // my-component.js
  ...
  import styles from './my-component.module.css'
  
  ...
      render(){
        // inside the render method
        return(
          ...
          <div className={styles.someclass}>
             ...
          <div>
          ...
        )
      }

  /* my-component.module.css */
  ...
  .someclass{
    ...
    color: red;
    ...
  }

Routes

• If your route components are top-level pages or contains a lot of code then lazyload them.
• Use the utils/asyncCompoment function to dynamically load the component. Eg.

  import asyncComponent from './utils/asyncComponent'
  // import SomePage from './pages/somepage' // INSTEAD of this
  import Spinner from './components/spinner' // optional loader component that can be used as a placeholder until the main component is loaded
  const SomePageImport = () => import('./pages/somepage') // postpone the import
  const SomePage = asyncComponent(SomePageImport,/*OPTIONAL*/Spinner)
  ...
  ...
    render(){
      // inside our render function
      return (
        ...
        <Route path="somepath" component={SomePage} /> // lazyloaded route
        ...
      );
    }
