Webpack Mastery: Bundle, Optimize & Scale Web Sites

Learn how webpack loads non-javascript files with loaders, such as CSS and images, by installing style-loader and css-loader and configuring module rules to bundle CSS into the JavaScript output.

Learn how plugins extend webpack by adding functionality like auto-generating HTML files. This lesson demonstrates installing html-webpack-plugin, configuring it in webpack, and producing a generated index.html with the bundle.

Explore webpack's mode option, switching between development and production to provide readable builds with source maps for debugging in development, and minified, tree-shaken bundles for production.

Transpile modern JavaScript with the pebble loader in webpack, converting arrow functions, classes, and string interpolation into older JavaScript for broad browser support.

Learn how to bundle CSS with Webpack using CSS loader and style loader, importing CSS into index.js and injecting it into the DOM, while configuring HTML Webpack Plugin.

Explore Webpack asset loading with file loader and url loader to manage images and fonts, copying assets to dist/assets or embedding files as base64, with size limits.

Learn how to automatically clean the output dist before builds in webpack 5 using the clean option and the clean-webpack-plugin, including how to exclude files or folders.

Replace the style loader with the MiniCssExtractPlugin to generate a separate css file for production. Configure the plugin and import index.css to enable caching.

Learn to visualize webpack bundles with the bundle analyzer plugin, identify large modules and duplicates, and generate a static HTML report to optimize bundle sizes.

Explore code splitting and lazy loading in Webpack by dynamically importing a module only when needed, creating separate chunks and improving page load time.

Explore how webpack's tree shaking removes unused code in production builds, exporting only used functions like add and ensuring unused code like multiply stays out of the bundle.

Learn how to use webpack dev server to serve a local bundle, auto rebuild and reload changes on save, with config options for static path, port, and auto-opening the browser.

Learn to bundle React apps with Webpack, transforming JSX with Babel and producing a single bundle, while using hot module replacement and a development server for rapid editing.

Learn to integrate webpack with a TypeScript project using ts-loader and HTML webpack plugin, configure tsconfig, enable hot module replacement, and build outputs to dist with bundle.js.

Build a simple weather app that uses open weather map APIs to fetch city weather and a five-day forecast with vanilla javascript, bundle with webpack, and configure the development server.

Set up a weather-dashboard scaffold by initializing npm and creating src, assets, public folders. Organize api.js, main.js, forecast.js, ui.js, with lazy loading for the five day forecast via openweathermap.

Install webpack, webpack-cli, webpack-dev-server, and html-webpack-plugin, then configure webpack with an entry and a content hash output to dist, and add start and build scripts.

implement the weather dashboard ui by building the html structure with a root div, header, search form, and a lazy-loaded five-day forecast section, and configure webpack css loaders.

Retrieve an open weather api key and copy it for use in your project. Securely load it via a .env file with dotenv and webpack DefinePlugin for process.env access.

Learn to build OpenWeatherMap API URLs with a base URL for weather or forecast, include the API key and encoded city, and implement Api.js getWeather and getForecast to fetch JSON.

Build a weather dashboard by fetching data from OpenWeatherMap, rendering current weather with icons for clear, cloudy, and rain, and displaying temperature, humidity, and wind speed.

Learn to lazy load forecast data with dynamic import in Webpack, render 12:00 entries into forecast cards, and optimize bundles for a scalable weather UI.
