Ok, here is what I found, a little strange:
firebase list
shows all firebase projects that you have access to, but they are not yet available (i.e. added as an alias to your current folder project).
CLI firebase-tools firebase deploy --project myproject1
, myproject1
, .firebaserc
= > , .
, , 2 :
firebase use --add
( )firebase use myproject1
= > , firebase deploy --project myproject1
( --only functions
)
