Generate production build with sourcemaps in Angular - CLI

How to keep sourcemaps after production build?

Right now, my command looks like this:

"build-prod": "ng build --app=release -prod && cp -R lang dist"

I tried changing it to:

ng build --app=release --sourceMap=true -prod && cp -R lang dist

but nothing changed.

If I do: ng build --sourcemap I get sourcemaps but then I get index.html instead of index.prod.html.

Is it possible to edit the first command to build sourcemap files?

this is my tsconfig.json file:

{
    "compileOnSave": false,
    "compilerOptions": {
        "outDir": "./dist/out-tsc",
        "sourceMap": true,
        "declaration": false,
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "target": "es5",
        "typeRoots": [
            "node_modules/@types"
        ],
        "lib": [
            "es2017",
            "dom"
        ]
    }
}

You should edit your angular.json like this

"configurations": {
    "production": {
        "fileReplacements": [
            {
                "replace": "src/environments/environment.ts",
                "with": "src/environments/environment.prod.ts"
            }
        ],
        "optimization": true,
        "outputHashing": "all",
        "sourceMap": false, // change to true

Then run

ng build --prod

But I wouldnt recommend you turn on source map in production because it will increase a bundle size
