GitHub workflow fails but still deploys due to nuxt generate

nuxt generate failed, but github workflow didn't know about it and still forced the deployment, causing the website to display errors.

My old code:

run: npm install && npm run generate

If an error occurs, the GitHub workflow will theoretically be interrupted. The problem lies in npm run generate. If a single page of nuxt generate reports an error, an error message will be displayed, but no error signal will be output, so the GitHub workflow does not know.

The code I modified adds two checks. If there is an error signal, exit. If the output contains the key string Composer.onError, exit.

run: |
  output=$(npm install && npm run generate)
  echo "$output"
  if [ $? -ne 0 ]; then
    echo "Installation or build failed, command execution returned a non-zero status code."
    exit 1
  fi
  if echo "$output" | grep -i "at Composer.onError"; then
    echo "Installation or build failed because output contains 'at Composer.onError'."
    exit 1
  fi
