Are js files minified3/28/2024 Many of the options described above can be set as command line arguments. Please see the Minimizing for Production section. It is crucial to minimize your CSS for production. + const = require('webpack-merge') Ĭonst common = require('./') Īvoid inline-*** and eval-*** use in production as they can increase bundle size and reduce the overall performance. + const HtmlWebpackPlugin = require('html-webpack-plugin') Let's start by installing webpack-merge and splitting out the bits we've already worked on in previous guides: npm install -save-dev webpack-merge With the "common" configuration in place, we won't have to duplicate code within the environment-specific configurations. In order to merge these configurations together, we'll use a utility called webpack-merge. While we will separate the production and development specific bits out, note that we'll still maintain a "common" configuration to keep things DRY. With this logical separation at hand, we typically recommend writing separate webpack configurations for each environment. In production, our goals shift to a focus on minified bundles, lighter weight source maps, and optimized assets to improve load time. In development, we want strong source mapping and a localhost server with live reloading or hot module replacement. The goals of development and production builds differ greatly. Please ensure you are familiar with the concepts/setup introduced in those guides before continuing on. This walkthrough stems from Tree Shaking and Development. I hope this explains why we use Query String versioning and please let me know if you have any other questions.In this guide, we'll dive into some of the best practices and utilities for building a production site or application. Imagine that every time the new product or article is added, and the cache is purged, new files also need to be fetched from the server. Generating a new file name every time the cache is purged would mean that every time Browser needs to fetch new files from the server, and therefore slows down the performance of the website.įor example, a JS-heavy website (themes and plugins) may have over 30 minified files. And this is where cache-control and expires header kicks in in the Browser Cache settings. W3 Total Cache is using the Versioning with Query Strings, and the reason for this is that we want to ensure that the static files remain cached in Browser (1 year for static files is recommended). I understand that he would be beneficial for you, but not for other users.Īs you may already know, there are different types of cache-busting: I hope this helps and let me know if you have any other questions. This will ensure that a new query string is generated and therefore force the browser to fetch the new version of the file from the server. If you make any changes in JS or CSS that are minified (or not), once the changes are done, go to either Performance>Browser Cache, or Performance>Minify and click on the Update Media query string button, just above the General sub-box, and make sure to save all settings and purge the cache after that The browser will fetch a new file version as it does not have the file with the query string cached.ĥ. If you check the website after that, you will see that the existing minified file has a random query string at the end:Ĥ. Enable “Prevent caching of objects after settings change” in Performance>Browser Cache, under the CSS/JS section, save all settings, and purge the cache.ģ. Minify is enabled and the files are cached:Ģ. What this option does is add a query string to a resource – ?xNNNNNġ. You can set this option globally, or set it for the individual file types (HTML&XML, JS&CSS, Media&Other files). We do, however, have an option for that and it’s called “Prevent caching of objects after settings change” in Performance>Browser Cache. Yes, you are correct when you say that after purging the cache, minify file names remain the same. Hello you for reaching out and I am happy to assist you with this.
