angular-cli run command after ng build
Define an npm script
"build":" "ng build"
and add the postbuild script, too.
"postbuild": "cpx ./package.json ./dist/",
This way the copy script gets called after you run npm run build
.
You can execute any custom script before or after any npm script. This is called 'hooks' and it is included in npm. In your case you can execute a 'post' hook but keep in mind that it is also possible to execute 'pre' hook.
define these 3 scripts in your package.json:
"hello": "echo execute hello",
"prehello": "echo execute prehello",
"posthello": "echo execute posthello"
