The following utilities improve performance by compiling and serving assets in memory rather than writing to disk: webpack 4 outputs a large amount of data with its stats.toJson() by default. However, this puts garbage collection pressure on projects that bundle thousands of modules. # Build Analysis. We can use the CleanWebpackPlugin to help us here. Let's start working on our actual app code now. Earlier, we discussed webpack plugins, which let you extend the webpack build process. Webpack production build output with content hashes included. There we go! The following tools have certain problems that can degrade build performance: Providing devtools or production optimizations, Providing different versions depending on target environment. This speeds up TypeScript type checking and ESLint linting by moving each to a separate process. I needed this because I had to use Webpack for a project and did not want to use another tool for compiling the SASS. That's when Webpack can help you to build a production ready bundle which comes with all the optimizations for your source code. For the purposes of this demo, we'll be setting up a webpack config from scratch using webpack 4. By default, the webpack mode is production where your code will be minified. Use the latest webpack version. Then, a user visits your app and their browser caches the main.js file. Turn this off in the options.output.pathinfo setting: There was a performance regression in Node.js versions 8.9.10 - 9.11.1 in the ES2015 Map and Set implementations. Devtool Remove dead code with Tree shaking. When that section isn't in the webpack config file, webpack defaults to using its own minimizer preferences, which includes minifying JavaScript when the mode is set to production. Webpack is a build tool for asset bundling and dependency management. We're already minifying our JavaScript for the production build, but we're not minifying our CSS yet. In these cases, you can increase the polling interval with watchOptions.poll. Minimize the module transfers between worker and main process. We specify for inject that we would like our JavaScript file to be injected into the body tag by setting the value to true. you could send the public/build directory to your production machine and it would work perfectly. How do I have to configure the webpack? The following string values are supported: We can use the webpack-merge plugin to manage shared code that multiple config files rely on. Providing the mode configuration option tells webpack to use its built-in optimizations accordingly.. string = 'production': 'none' | 'development' | 'production' Usage. This line: Now if you run yarn build, you'll see that both your JavaScript and your CSS have content hashes included: If you run yarn build again and compare your new output to your old output, you'll notice that the content hashes are exactly the same both times. There's a plugin for that! Now if you run yarn build this time to generate the production build, you should get some output in your terminal that looks like this: Note that it actually generates a CSS file now, and the content hash is included in the file name. The latest recommended version of webpack is: Staying up-to-date with Node.js can also help with performance. Loaders instruct webpack how to handle different file types. So, how can we clean up the duplication in our webpack config files? Do you really need them? Wouldn't it be nice if webpack could delete the old unneeded output each time we do a new build? This file also looks very similar to our original config file. We'll explore a handful of helpful plugins as we continue to improve our webpack config throughout the rest of this article. webpack-dev-server after v3.1.3 contained a substantial performance fix to minimize the amount of data retrieved from the stats object per incremental build step.

Profile them to not introduce a performance problem here. The built-in watch mode will keep track of timestamps and passes this information to the compilation for cache invalidation. Here we've specified that the mode is production and that we would like the source-map option for source maps, which provides separate source map files for minified code. webpack 4 has introduced development and production modes. We support yarn PnP version 3 yarn 2 berry for persistent caching. Webpack has a rich ecosystem of modules called "plugins", which are libraries that can modify and enhance the webpack build process. Get started Log in. In this case, we want to handle files with a .css extension. Ok, back to our demo app. The goals of development and production builds differ greatly. For example, if you've visited a website, and your browser had to download assets like JavaScript, CSS, or image files, your browser may cache those files so that it doesn't have to request them from the server again. So, the contents of our webpack.config.common.js file will be: And now, we can merge this shared config object into our development config like this: And we can merge the shared config object into our production config like this: Look how much shorter and cleaner those two files look! Our app will just use vanilla JavaScript so that we don't get bogged down with any framework-specific details. For some configuration options, (HMR, [name]/[chunkhash]/[contenthash] in output.chunkFilename, [fullhash]) the entry chunk is invalidated in addition to the changed chunks.
