Translations::generate_translation_strings() │ private │ WC 1.0

Combine translation chunks when plugin is activated.

This function combines JSON translation data auto-extracted by GlotPress from Webpack-generated JS chunks into a single file. This is necessary since the JS chunks are not known to WordPress via wp_register_script() and wp_set_script_translations().

Method of the class: Translations{}

No Hooks.

Return

null. Nothing (null).

Usage

// private - for code of main (parent) class only
$result = $this->generate_translation_strings();
