问题
I have an npm script where I want to match both ts and tsx file extensions... something like below:
"test": "mocha ..... app/test/**/*.spec.{ts,tsx}"
However, the above syntax doesn't work. What's the correct syntax for doing this?
回答1:
Your pattern is correct. Your problem is that your shell is attempting to expand your glob for you instead of letting mocha expand it.
To fix this, you need to double-quote your glob (note that double-quotes must be JSON-escaped with \):
"test": "mocha ..... \"app/test/**/*.spec.{ts,tsx}\""
Single quotes will also work (and won't need JSON-escaped) if you don't care about Windows support.
