Unsolved hook method is not triggering from custom theme library.js

[aniinprni]

Hi i have created a custom theme so that new look and feel. but when a composer is loaded i try to fire a hook method. but that server side hook is not at all calling.

plugin.json

{ "hook": "filter:composer.formatting", "method": "resetComposerFormatting" },

library.js

library.resetComposerFormatting = function (hookData,callback) {
	if(hookData.options.length>0){
		hookData.options = hookData.options.map(e=>{
			return e.name != "thumbs";
		});
	}
	callback(null,hookData);
};

But this method is not at all firing. did i miss anything ?

Is your theme activated? Is library exported? Is that file executed at all? Try putting console logs in various places.

@pitaj library.js file is not at all executed. please to let me know how to do it. How to activate it?

@aniinprni you might try renaming it to index.js instead. Or set "main": "library.js", in package.json
