How to remove a tag from production?

Question

Vue.js

How to remove the template tag from production???
This means that the template code does not even get into the compilation.

...
<template v-if="process.env.NODE_ENV !== 'production'">
Видно только в разработке
</template>
...

I suppose we need to write something in v-if, but I don’t know what.

Answer 1

If it is assembled by webpack (for example, from vue cli or quasar), then something like this:

...
        <div v-if="dev">
           dev
        </div >
...

...
  computed: {
    dev() {
      return process.env.DEV;
    }
  },
...

Answer 2

yes, build via vue cli. But alas, it didn't help. It is clear that it is not visible, but this block does not disappear in the final app.js anyway.
You can of course through javascript, but it's inconvenient. I want a simple and effective solution that removes the code from the final assembly...
