UGRENT: I seem to have an incomplete file e.g. assets/js.custom/app/chat/chat.js does not exist

Whenver I put custom HTML in index.html it disurpts the theme and I cannot get this to be displayed:

Hi,

You can check this to get started with Metronic.

In order to add your sass global you just need to create your sass file in src/sass/layout/_support-chat.scss in order to include your CSS code globally within the bundle CSS file assets/css/style.bundle.css.

To add global JS code you can add your JS script in src/js/layout and it will be compiled into assets/js/scripts.bundle.js.

Under src/js/custom you can add custom scripts and get them compiled into src/js/custom

Then recompile your assets folder with Gulp

Please note that the build tools are required only in the development environment just to compile the assets when the source folder files are modified. In the hosting/server deployment, you will only need the compile assets, no need to install the build tools dependencies there.

Regards

This is urgent
