Fix: Dynamic import is only possible with --module commonjs or esnext

Recently, I am trying to introduce dynamic import of modules in our Angular application. So that, we can have reduced bundle size for a better performance of course.

We are not there yet but we do have an action item though. ^_^

During the tryouts I faced the following error saying:

error TS1323: Dynamic import is only supported when '--module' flag is 'commonjs' or 'esNext'.

As the error suggests we have to specify or change our module type in the following files as specified.

  • tsconfig.json
  • tsconfig-aot.json
"compileOnSave": false,
"compilerOptions": {
"module": "esnext" // add this line

Apply the changes in the files those matter to your case.

For me it was the tsconfig-aot.json as we build our app using --aot flag. \O/
