Since html-minifier also uses clean-css and uglify-js, setting minifyJS or minifyCSS to true will embed the settings you have supplied for those minifiers automatically. You can provide your own settings as an object if you want some different methods to be used.
CLI: If you are using the command-line API, it may be helpful to know that the flags come in one of three forms: --foo, --foo=bar, or --foo:bar. The form --foo is used for enabling boolean flags such as --minify, the form --foo=bar is used for flags that have a single value and are only specified once such as --platform=, and the form --foo:bar is used for flags that have multiple values and can be re-specified multiple times such as --external:.
This setting lets you pass a regular expression to esbuild to tell esbuild to automatically rename all properties that match this regular expression. It's useful when you want to minify certain property names in your code either to make the generated code smaller or to somewhat obfuscate your code's intent.
When enabled, the generated code will be minified instead of pretty-printed. Minified code is generally equivalent to non-minified code but is smaller, which means it downloads faster but is harder to debug. Usually you minify code in production but not in development.
By default esbuild won't minify the names of top-level declarations. This is because esbuild doesn't know what you will be doing with the output. You might be injecting the minified code into the middle of some other code, in which case minifying top-level declaration names would be unsafe. Setting an output format (or enabling bundling, which picks an output format for you if you haven't set one) tells esbuild that the output will be run within its own scope, which means it's then safe to minify top-level declaration names.
If your cache is growing significantly, this could mean one of your CSS or JS files is dynamic and changes on every pageview. In that case, you would need to add the file to the ignore list, else the cache would grow indefinitely (because obviously the original files themselves are dynamic and when you minify, the plugin sees a different file).
Third-party tools, such as Gulp and Webpack, provide workflow automation for bundling and minification, as well as linting and image optimization. By using bundling and minification, the minified files are created prior to the app's deployment. Bundling and minifying before deployment provides the advantage of reduced server load. However, it's important to recognize that bundling and minification increases build complexity and only works with static files.
One of the easiest ways to minify CSS or JS is to use WP Rocket. The plugin can also optimize the CSS delivery, defer JS and delay JS execution. No risks are taken: you have a 14-day money-back guarantee if you see no speed improvements.
In order to enable HTML minify and select which library to use, navigate to Performance > General Settings and scroll down to the Minify section. Enable minification, and choose which library to use:
Stripping all of that down actually makes the file that you send to the user a lot smaller. Because when you minify it, you remove all the extra spaces, all the line breaks, and all the comments. Stripping all that can save up to 30-40%, or even 50% of file size in some cases. There really is no benefit of sending that stuff to the end-users, so minifying saves time and money for everyone.
Obviously, this is just a small example using a snippet of CSS code, but you can imagine the the amount of space this would save when minifying thousands of lines of code. So, if you wanted to do this manually by hand, technically you could. But you would run a high risk of error and needlessly shave valuable time off or your life!
