Use firebase-deploy-directory as a replacement for firebase deploy if you use Firebase hosting and want to deploy different parts of your site from different repos or directories.

For example, if your main website is hosted at https://example.com and you have a separate repo for your blog hosted at https://example.com/blog.

In the repo for your main website, where you keep your firebase.json, you would run

firebase-deploy-directory \
  --project <firebase-project-name> \
  --replace-config \ 
  --directory <directory-that-contains-website-files e.g. build/> \
  --exclude-subpath blog \
  --commit

If you're running this from CI, then add --token $FIREBASE_TOKEN, where $FIREBASE_TOKEN is the token you got from firebase login:ci.

In the repo for your blog, run

firebase-deploy-directory \
  --project <firebase-project-name> \
  --directory <directory-that-contains-website-files e.g. build/> \
  --subpath blog \
  --commit

You can leave off the commit flag to do a dry run.

You can deploy from multiple directories, just add a new --exclude-subpath flag for each path. For example, if you're deploying /blog and /changelog from different repos, your deploy command for the main repo would be:

firebase-deploy-directory \
  --project <firebase-project-name> \
  --replace-config \ 
  --directory <directory-that-contains-website-files e.g. build/> \
  --exclude-subpath blog \
  --exclude-subpath changelog \  
  --commit
