run strict compilation in ng build angular

Question

I'm using angular-cli in my project. I have these two configs in my package.json :

"scripts": {
  "ng": "ng",
  "build": "ng build --base-href /test/",
  "prod": "ng build --prod --base-href /test/"
}

--prod detects compilation problems (like dead code) as it's said in angular documentation but it's not run in the build command that we use in development mode (actually we use npm start but it does the same thing).

This results in problems detected too late in our continuous delivery tool instead of during development.

I don't want to add the --prod for developement angular compilation tasks and i tried to see it there are options in the "tsconfig" file documentation but i didn't find any.

I read that --prod launches an uglification with uglifyJs which runs this strict compilation.

How can i tell angular to launch a strict compilation in my development "build" task the same way it's executed in --prod ? (i also tried the "user strict mode" in my files but didn't change anything).

I'm using angular 5 with the Typescript 2.x version.

Thank you in advance.

All you have to do is add the --aot flag to any time you run a build which should have stricter checking. For example, your scripts could be configured as:

"scripts": {
  "ng": "ng",
  "build": "ng build --aot --base-href /test/",
  "prod": "ng build --prod --base-href /test/"
}
