Module 1: Introduction to Webpack4:58
Webpack is a module bundler that starts at an entry point and outputs optimized bundles by processing JavaScript, CSS, and other assets, enabling code splitting with loaders and plugins.
Module 2: Installation and Basic Webpack Setup4:34
Install webpack and dependencies, initialize a Node.js project, and set up a webpack.config.js with entry and output. Organize src and dist structure and prepare for loaders, plugins, and development tools.
Module 3: Modules and Loaders4:13
Learn how webpack treats JavaScript, CSS, and images as modules and extend it with loaders like Babel, CSS, and file loader to transpile and bundle multiple file types.
Module 3: Modules and Loaders (2)1:00
Learn how Webpack treats files as modules and uses loaders, including Babel, CSS loader, and file loader, to bundle JavaScript, styles, and images with correct output paths.
Module 4: Webpack Plugins4:03
Discover how webpack plugins extend the build process to improve performance, code quality, and output management, with practical use of HTML Webpack plugin, Minix extract plugin, and Clean Webpack plugin.
Module 4: Webpack Plugins (2)2:17
Learn how webpack plugins optimize front-end builds by extracting css, injecting assets into html, cleaning the output directory, and minifying code, with code splitting and tree shaking forthcoming.
Module 5: Development Workflow with Webpack3:54
Explore development workflow with webpack by configuring development mode, leveraging webpack dev server for live reloading, and using hot module replacement to speed debugging and provide better source maps.
Module 5: Development Workflow with Webpack (2)1:52
Learn how hot module replacement speeds development by updating only changed modules while preserving app state, and optimize with Webpack dev server, source maps, code splitting, and tree shaking.
Module 6: Optimization and Performance3:56
Minify JavaScript and CSS for production with webpack's terser plugin and CSS minimizer, and implement code splitting via entry points, vendor splitting, and dynamic imports to boost performance and caching.
Module 6: Optimization and Performance (2)2:43
Use caching with hashed file names to speed repeat visits and ensure updated assets. Minify JavaScript and CSS, optimize images, and implement code splitting with dynamic imports for Webpack builds.
Module 7: Handling Different File Types4:04
Learn how Webpack handles images, fonts, and multimedia assets with loaders, optimize image sizes for production, and implement image optimization to preserve quality.
Module 7: Handling Different File Types (2)2:00
Implement the srcset attribute with Webpack's image loader and responsive loader to generate multiple image sizes for low, medium, and high density screens. Benefit from improved performance and reduced bandwidth.
Module 8: Testing with Webpack4:02
Integrate testing into your webpack workflow by bundling test files for frameworks like Jest and Mocha. Configure environments, Babel, and test runners to run unit and integration tests efficiently.
Module 8: Testing with Webpack (2)3:01
Explore mocha and tools like chai for asynchronous testing across browser and Node.js, and learn to integrate webpack with Jest or Mocha for automated, watch-mode test runs and coverage.
Module 9: Advanced Webpack Configuration4:09
Module 9: Advanced Webpack Configuration (2)2:26
Module 10: Conclusion and Best Practices4:14
Wrap up your webpack knowledge with performance and security best practices, including caching, asset optimization, code splitting with dynamic imports, tree shaking, and parallel processing.
Module 10: Conclusion and Best Practices (2)3:28
Configure environment variables for development, staging, and production, create reusable loaders and plugins to scale webpack, manage dependencies with workspaces, use source maps, and automate npm or yarn scripts.
