Reactjs Project Structure and Best Practices

Organizing your project structure is crucial for the scalability and maintainability of a ReactJS project. There are different ways to structure a React project, and the best approach may depend on the specific needs of your project. Here's a suggested folder structure for a large ReactJS project:

/src
  /assets
    /images
    /styles
      global.css
  /components
    /Common
      Button.js
      Input.js
    /Feature1
      Feature1Component1.js
      Feature1Component2.js
    /Feature2
      Feature2Component1.js
      Feature2Component2.js
  /containers
    /Feature1Container.js
    /Feature2Container.js
  /contexts
    AuthContext.js
  /hooks
    UseFetch.js
    UseAuth.js
  /services
    ApiService.js
    AuthService.js
  /redux
    /actions
      authActions.js
      feature1Actions.js
      feature2Actions.js
    /reducers
      authReducer.js
      feature1Reducer.js
      feature2Reducer.js
    /store
      configureStore.js
  /routes
    AppRouter.js
  /utils
    helpers.js
  App.js
  index.js

Explanation:

assets: Contains static assets such as images and global styles.

components: Reusable presentational components. Group them by feature or create a common folder for components used across features.

containers: Container components that connect to the Redux store. They generally wrap presentational components and handle data fetching and state management.

contexts: React Contexts that provide global state management.

hooks: Custom hooks that can be reused across components.

services: External services, such as API services or authentication services.

redux: Redux-related files including actions, reducers, and the Redux store configuration.

routes: Define your application routes here using a router (e.g., React Router).

utils: Utility functions that are not specific to any component or feature.

App.js: The main component where you set up your application structure.

index.js: The entry point of your application.

This is just one possible structure, and you may need to adapt it based on your project's specific requirements. Additionally, tools like Create React App or Next.js come with their own conventions for project structure.

If you want to create a common layout with a header, footer, and navigation that is consistent across multiple pages, you can extend the folder structure to include a layouts folder. Here's an updated structure:

*For Layout structuring *

/src
  /assets
    /images
    /styles
      global.css
  /components
    /Common
      Button.js
      Input.js
    /Feature1
      Feature1Component1.js
      Feature1Component2.js
    /Feature2
      Feature2Component1.js
      Feature2Component2.js
  /containers
    /Feature1Container.js
    /Feature2Container.js
  /contexts
    AuthContext.js
  /hooks
    UseFetch.js
    UseAuth.js
  /layouts
    /MainLayout
      Header.js
      Footer.js
      Navigation.js
  /services
    ApiService.js
    AuthService.js
  /redux
    /actions
      authActions.js
      feature1Actions.js
      feature2Actions.js
    /reducers
      authReducer.js
      feature1Reducer.js
      feature2Reducer.js
    /store
      configureStore.js
  /routes
    AppRouter.js
  /utils
    helpers.js
  App.js
  index.js

Explanation:

layouts: Contains layout components that define the overall structure of your pages. In this example, there's a MainLayout folder with Header, Footer, and Navigation components.
You can then use these layout components within your routes or pages. For example, your AppRouter.js might look like this:

// AppRouter.js
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import App from './App';
import MainLayout from './layouts/MainLayout';
import Feature1Container from './containers/Feature1Container';
import Feature2Container from './containers/Feature2Container';

const AppRouter = () => {
  return (
    <Router>
      <Switch>
        <Route path="/feature1">
          <MainLayout>
            <Feature1Container />
          </MainLayout>
        </Route>
        <Route path="/feature2">
          <MainLayout>
            <Feature2Container />
          </MainLayout>
        </Route>
        {/* Add more routes as needed */}
        <Route path="/">
          <MainLayout>
            <App />
          </MainLayout>
        </Route>
      </Switch>
    </Router>
  );
};

export default AppRouter;

**App.js **

// App.js
import React from 'react';
import AppRouter from './routes/AppRouter';

function App() {
  return (
    <div className="App">
      <AppRouter />
    </div>
  );
}

export default App;
