Vuepress should fail if imported code snippets is not found #1872
Description
Feature request
What problem does this feature solve?
Currently, when trying to import a code snippet from a non-existing file, vuepress will create a snippet that says "File not found".
Input:
<<< @/file_does_not_exist.js
Output:
Not found: /app/file_does_not_exist.js
This is a problem because it results in broken documentation. In a CI/CD environment it would be great to surface this problem early.
What does the proposed API look like?
Vuepress should fail to render if a code snippet isn't found.
