`npm run serve` does not fail on errors-CodePudding

I have a Vue view, somethink like:

<script setup lang="ts">
import { firstItem } from "@/path/to/my/file";

onMounted(async () => {
  let f1 = getFirstItem();
  let f2 = getSecondItem();
});

As you can see, there is an Import for firstItem, but I forgot to add an import for secondItem.

My issue - Why such a code is passing npm run serve successfully? In fact, the website does not work (as expeted). How can I make npm run serve to fail instead of this confusing scenario that I was sure everything is OK with my code, and was not aware to this error?

By The Way, npm run lint DO show this error, but I do not remember to run npm run lint bfore every npm run serve

CodePudding user response：

It is a runtime error, not a compile time error. If you run a type checker before you run npm run serve, the command will fail.

You can also change your typescript config settings to report an error.

Somewhere in your typescript settings, you are allowing undeclared global functions, or have disabled the type checking.

Sometimes this happens when the global object is overriden as type any.

I sloved the issue by editing package.json file, and adding lint call on each serve:

"scripts": {
    "serve": "vue-cli-service lint && vue-cli-service serve", ...
