Webpack 5 Full Course (Babel, PostCSS, npx, Node.js & npm)

Webpack is used to run TASKS. MOST COMMON TASKS for JavaScript files: - bundling - minification - transpiling and polyfills (Babel) - tree shaking / dead code elimination - lazy loading MOST COMMON TASKS for CSS files: - bundling - optimizations like above (minification, vendor prefixes, px to rem -- all with PostCSS) - CSS Modules - Sass/SCSS compilation to CSS MOST COMMON TASKS for all file types: - add hash to file names (in practice you cache static assets like HTML/CSS/JS files on a CDN, when you change a file you need to 'bust' the old file from the cache which is commonly done by comparing file names -- if the file name has changed (e.g. from main.234asdf.js to main.74545fds.js then the old file will be removed from cache and new is put in -- '234asdf' and '74545fds' are hashes and based on file contents, hash only changes when content of file changed) The above is for a 'BUILD': creating a production-ready version of your project, but webpack also provides help during development (e.g. with a DEVELOPMENT SERVER & SOME TASKS also need to be run during development like Sass compilation to CSS). Therefore, it has become an ALL-IN-ONE TOOL for front-end development. This tutorial will also explain IMPORTANT RELATED CONCEPTS like Node.js, npm, npx, terminal / shell, ES Modules, config files, browserslist, core js (polyfills) and much more -- all crucial for understanding webpack! 👉 Professional JavaScript Course: https://bytegrad.com/courses/professi... 👉 Professional CSS Course: https://bytegrad.com/courses/professi... 👉 Email newsletter (React + Next.js course out soon!): https://email.bytegrad.com 💻 Premium Courses: Professional JavaScript: https://bytegrad.com/courses/professi...

No, it gives us many optimizations for all file types (JS, CSS, etc.) in 1 tool 24:43 - Webpack for build process in real-world project 26:23 - npm hosts packages -- webpack is a package 27:41 - Node.js for running JavaScript code 29:22 - Terminal in VS Code (shells are cmd / PowerShell / bash) -- IDE 31:36 - node -v command 32:04 - npm init command (to make project a package -- npm treats everything as a package) 32:57 - package.json file 33:39 - npm install command (to install webpack package) 35:00 - After installing npm package (devDependencies, package-lock.json, node_modules) 37:47 - Webpack configuration (webpack.config.js, mode, entry file, dependency graph, output file) 44:27 - Running webpack (bin path vs npm script vs npx) 49:33 - Supporting older browsers 50:29 - caniuse.com for browser support 52:31 - Transpiling with Babel 58:03 - Loaders (babel-loader for JS-files, later PostCSS-loader for CSS-files) 1:00:16 - Babel configuration (babel.config.js) 1:02:00 - Transpiling vs Polyfills (core-js) 1:06:36 - browserslist for targeting browser support 1:09:44 - Webpack for CSS-files (minification, vendor prefixes, px to rem) with PostCSS 1:12:48 - Import CSS file in JavaScript file? Yes, so webpack can discover this file 1:14:55 - PostCSS configuration (postcss.config.js) 1:18:03 - Extracting CSS into its own final output file (MiniCSSExtractPlugin or mini-css-extract-plugin, needs css-loader) 1:23:45 - Final result 1:27:41 - Professional JavaScript Course preview #webpack #webpack5 #whatiswebpack #webpacktutorial #webpackcrashcourse #webdevelopment #coding #programming
