How can I make sure JavaScript files are minified in a specific order?

WP Compiler supports .manifest files for JavaScript. This is a custom file format in which each line consists of a relative file path to a JS file, a relative path to a directory containing JS, or a relative path to another .manifest file. for clarity, lines beginning with a hash symbol (#) are treated as comments. Here is an example of a manifest file: # # This is a sample JavaScript manifest file for WP Compiler # all paths are relative to the current manifest file # First we are going to load specific files that have to come first test-script.js test-script2.js # Now let's load a sub-manifest partials/js.manifest # Finally, let's load a folder whose contents # don't need to be in a specific order external-scripts/

Frequently Asked Questions

Common questions about WP Compiler

The easiest way to compile your JS is to store it all in a single directory. If you set your compilation source to be the directory path, all JS files in the directory will be combined and minified.

WP Compiler supports .manifest files for JavaScript. This is a custom file format in which each line consists of a relative file path to a JS file, a relative path to a directory containing JS, or a relative path to another .manifest file. for clarity, lines beginning with a hash symbol (#) are treated as comments. Here is an example of a manifest file: # <js.manifest> # This is a sample JavaScript manifest file for WP Compiler # all paths are relative to the current manifest file # First we are going to load specific files that have to come first test-script.js test-script2.js # Now let's load a sub-manifest partials/js.manifest # Finally, let's load a folder whose contents # don't need to be in a specific order external-scripts/

Unfortunately, there is a limit to how many of the immense number of node.js build processes available can be replicated in native PHP. Please let us know about which features you'd most like to see tackled next.
