How to increase cache expiration date with firebase tools?

Question

I cannot seem to make the max-age work properly with any file. I want to increase the expiration of the cache, and I've been trying to increase only the image time for testing purposes. Still, chrome and firefox state the max-age for the image as 3600 with this json file

Answer 1

The source for the header isn't matching the input path of images in that folder - it needs to start with a /:

{
  "firebase": "sistema-de-oficios",
  "public": ".",
  "ignore": [
    "firebase.json",
    "**/.*",
    "**/node_modules/**"
  ],
  "headers": [{
    "source": "/css/images/*.@(jpg|jpeg|gif|png)",
    "headers": [{
      "key": "Cache-Control",
      "value": "max-age=7200"
    }]
  }]
}

Also, make sure you're on the latest version of firebase-tools which is currently 1.1.4 at the time of writing.
