typescript - Angular-cli : How to ignore class names from being minified

Question

For an application we need to keep the classname not minified because we use

var className = myObject.constructor.name;
export class myObject{ ... }

when we run

ng build -- pro

the class name gets minified in a random name.

Answer 1

Angular cli builder supports NG_BUILD_MANGLE, NG_BUILD_MINIFY, NG_BUILD_BEAUTIFY node environment params (checked in version 8).

You can set them when running npm script in following way: env NG_BUILD_MANGLE=false NG_BUILD_MINIFY=false NG_BUILD_BEAUTIFY=true ng build --prod

This will result in unminified output, yet tree shaking and other optimizations will still be applied (compared to just turning off optimization).
