Angular cleaning up build files?

Question

Angular generates a lot of trash from a .ts file.

app.component.js
app.component.spec.js.map 
app.component.js.map
app.component.spec.ts     
app.component.spec.js

Is there any simple way to delete of that, a lot of build systems support clean,

make clean
git clean

How do you do this in angular

My test case.

1. Download Angular's Hero Demo toh-3
2. Unzip it
3. Jump into the directory
4. Run npm install
5. Run npm start

Now from the main.ts you now have main.js and main.js.map

In my own project, where I'm working along with the angular-cli, I actually have .spec files too.

Answer 1

Check this method

I make build: ng build --env prod which will write it under dist folder Then I run ng serve and my build is gone.

Answer 2

Are you using the Angular CLI? If so, by default it no longer generates all of these "trash" files.
