Angular Error

# Error ng build "should NOT have additional properties(es5BrowserSupport)."
# Fix: update angular devkit build angular
ng update @angular-devkit/build-angular
# jika masih error, you can edit angular.json file and find "es5BrowserSupport": true and comment it.

# Error ng build --prod "bundle initial-es2015 exceeded maximum budget"
# Fix: edit angular.json and find "budgets" keyword.

# masalah build --prod yg tetap membaca environment.ts yang seharusnya membaca environment.prod.ts
ng build --prod --configuration production

# error build
Index html generation failed.
undefined:5:988957: property missing ':'
# penyebab:
# file CSS (contoh: projects/storefront/src/scss/icons/feather/style.css), ada font-face src: url(data
# semula ada tanda petik src: url("data:application/x-font-ttf;charset=utf-8;base64 ... ")
# fix hapus tanda petik menjadi src: url(data:application/x-font-ttf;charset=utf-8;base64 ...)

# error build
error TS7015: Element implicitly has an 'any' type because index expression is not of type 'number'.
4     apiUrl: window["env"]["apiUrl"] || "default"
# sepertinya ini karena di tsconfig, strict: true.
# fix: ubah file tsconfig.json tambahkan baris berikut pada compilerOptions
compilerOptions:{

  "suppressImplicitAnyIndexErrors": true,
  "strictNullChecks":false,
  "strictPropertyInitialization": false,
