Webpack2 React‑Redux Boilerplate: Architecture, Features, Configuration and Best Practices

The article presents a Webpack2‑React‑Redux boilerplate hosted on GitHub, designed as a semi‑automatic scaffolding tool for modern frontend projects. It emphasizes a clear separation between core application code and the scaffolding, encouraging developers to understand the underlying concepts rather than rely on a black‑box starter.

Features

Supports multiple build targets (development, pure frontend, and universal rendering) with smooth switching.

Single configurable Webpack file that adapts to environment variables via npm scripts.

Multiple entry points for SPA or multi‑page applications, handling separate HTML, JS, and CSS bundles.

Hot module replacement for rapid development.

Automatic polyfills for ES6, React, Flexbox, etc.

Automated asset management (HTML generation, image/font handling, CSS extraction).

Code splitting and asynchronous component loading to reduce bundle size.

Redux Discussion

The author questions whether Redux is always necessary, illustrating a simple login‑redirect example implemented both with plain React and with Redux. The Redux version demonstrates pure‑function reducers, predictable state flow, and easier testing, while acknowledging the added boilerplate.

const store = createStoreWithMiddleware( rootReducer, initialState, typeof window === 'object' && typeof window.devToolsExtension !== 'undefined' && __DEV__ ? window.devToolsExtension() : f => f);

Personal Best Practices

Prefer async/await over raw Promise chains.

Wrap fetch in a reusable utility (e.g., fluent‑fetcher ).

Avoid excessive inline styles; keep CSS files alongside component files.

Write pure functions where possible to simplify reasoning.

Quick Start & Commands

Clone the repository, run npm install (or yarn ), then use npm start for development with hot reloading. Build the production bundle with npm run build , which can output hash‑history SPA bundles or Cordova‑compatible assets.

Library Mode

By setting the library flag in dev-config/apps.config.js and running npm run build:library , the project can export a single ES6 class that can be included via a <script> tag on any page.

Server‑Side Rendering (SSR)

The boilerplate includes an SSR example using react_app . After configuring ssrServer in apps.config.js , run npm run build:ssr to generate server bundles. The server renders the initial HTML on the first request and then hands over to the client for subsequent navigation.

app.get('/*', function (req, res) { const memoryHistory = createHistory(req.originalUrl); const store = createStore(memoryHistory); const history = syncHistoryWithStore(memoryHistory, store); match({history, routes: getRoutes(), location: req.originalUrl}, (error, redirectLocation, renderProps) => { if (error) { res.status(500).send(error.message) } else if (redirectLocation) { res.redirect(302, redirectLocation.pathname + redirectLocation.search) } else if (renderProps) { let html = renderToString( ); res.status(200).send(renderHTML(html, {key: "value"}, ['/static/vendors.bundle.js', '/static/redux.bundle.js'])); } else { res.status(404).send('Not found') } }); });

Authentication

Route protection can be added via the onEnter hook, checking user credentials before allowing navigation.

Isomorphic Redux

The project adopts the “ducks” pattern for Redux modules, grouping actions, action creators, and reducers in a single file, and uses redux‑thunk (or a custom promise middleware) for async flows.

Conclusion

The boilerplate provides a comprehensive, production‑ready setup for React‑Redux applications, covering development tooling, code organization, SSR, library export, and practical tips, while warning users not to rely on it blindly without understanding its internals.
