A modular theme.json compiler for WordPress themes.

⚠️ Warning

The compile and watch commands will overwrite your theme.json file in the specified theme directory.

A backup is created automatically, but you may want to manually make one as well since this tool has not been thoroughly tested yet.

• Split theme.json into modular files for easier management
• Compile modular files back into a single theme.json
• Supports granular splitting for settings, styles, and more
• CLI commands for compile, split, and watch

npm install @builtnorth/wp-theme-json-compiler

• split: Splits a current theme.json file into modular JavaScript files in the theme-config directory. This makes it easier to manage and edit theme settings in a structured way.
• compile: Compiles all modular files from the theme-config directory back into a single theme.json file. Automatically creates a backup of the existing theme.json before overwriting.
• watch: Watches the theme-config directory for changes. When a change is detected, automatically recompiles theme.json (creating a backup the first time in each session).

npx @builtnorth/wp-theme-json-compiler compile --theme-path=wp-content/themes/your-theme
npx @builtnorth/wp-theme-json-compiler split --theme-path=wp-content/themes/your-theme
npx @builtnorth/wp-theme-json-compiler watch --theme-path=wp-content/themes/your-theme

• If --theme-path is omitted, the current working directory is used.

Add to your root package.json scripts:

"theme-json:compile": "wp-theme-json-compiler compile --theme-path=wp-content/themes/your-theme",
"theme-json:split": "wp-theme-json-compiler split --theme-path=wp-content/themes/your-theme",
"theme-json:watch": "wp-theme-json-compiler watch --theme-path=wp-content/themes/your-theme"

• By default, operates on theme.json and theme-config in the current working directory.
• Use --theme-path to specify a custom theme directory.

Before overwriting your existing theme.json, the compiler automatically creates a backup named theme.backup.json in the same theme directory. This occurs every time you run the compile command, and once per session when using the watch command (the first time a change is detected).

• The backup file is always named theme.backup.json and will be overwritten on subsequent runs.
• This helps prevent accidental data loss. To restore, simply rename or copy theme.backup.json back to theme.json.
• Always verify your changes and keep your own version control backups for extra safety.
