How to deploy all Supabase edge functions at once?

Question

I have multiple Supabase edge functions I want to deploy simultaneously when I push to production. These are all the functions in my .supabase/functions folder, ie:

.supabase
    functions
        my_function_1
            index.ts
        my_function_2
            index.ts
        ...

The Supabase CLI docs explain how to deploy a single function with supabase functions deploy <Function name> [flags], but don't seem to mention deploying all of them together.

Do I have to run the deploy command once for each function? For ex:

supabase functions deploy my_function_1 && supabase functions deploy my_function_2

Or is there a simpler way?

I tried simply running supabase functions deploy but got this error indicating that I need to pass a function name as an arg:

Error: accepts 1 arg(s), received 0
Usage:
  supabase functions deploy <Function name> [flags]

The firebase functions equivalent would be firebase deploy --only functions (docs)

Answer 1

It is now possible to deploy all functions to a linked project in Supabase:

Just run this:

supabase functions deploy

You can also set parameters (that will be used on all deployments):

supabase functions deploy --import-map import_map.json  --no-verify-jwt  --project-ref xxsupanachoxx
