I can’t seem to get any minify config overrides for the CLI to work. If I’m reading everything correctly the following should work, but is not.

aurelia.json

```auto
"minify": {
    "dev": false,
    "prod": {
        "keep_classnames": true
    }
}

```

What bundler are you using?  
I think webpack disrepects most of the aurelia.json configs.

The `keep_classnames` options is correctly passed to terser to minify the bundle file.

The reason for that not working is **there is not any class left after TypeScript compiling**.

For example, TS compiled app.ts to something like this

```auto
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
var App = (function () {
    function App() {
        this.message = 'Hello World!';
    }
    return App;
}());
exports.App = App;

```

The `App` is not using class syntax anymore, it’s a function. Two possible solutions.

1. use `"keep_fnames": true`

- Tested, it works.

1. or, adjust tsconfig.json `compileOptions.target` to newer JS standard.
