How to deploy some functions to Cloud Functions for Firebase without affecting some other functions?
FirebaseGoogle Cloud-FunctionsFirebase ToolsFirebase Problem Overview
When I run
firebase deploy --only functions
it reads the index.js
file and updates all functions exported from that file. If on the previous deploy there was a function named a
, and in the current deploy there is no such function, a
will be deleted.
In other words, the effect is the same as if all existing functions were deleted and then the all functions from the current index.js
file were added.
Is it possible to add/update/delete individual functions?

Solution 1 - Firebase
Firebase CLI tools 3.8.0 has added the ability to deploy specific functions.
firebase deploy --only functions:func1,functions:func2
--only <targets>
only deploy to specified, comma-separated targets (e.g. "hosting,storage"). For functions,
can specify filters with colons to scope function deploys to only those functions (e.g. "--only functions:func1,functions:func2").
When filtering based on export groups (the exported module object keys), use dots to specify group names
(e.g. "--only functions:group1.subgroup1,functions:group2)"
Solution 2 - Firebase
The following way worked for me to deploy a particular function without affecting my other functions, where specificFunctionName
is the function I wanted to deploy
firebase deploy --only functions:specificFunctionName
To copy the command quickly in terminal:
firebase deploy --only functions:

There is currently no way to deploy a single function with the Firebase CLI. Running firebase deploy
will deploy all functions.
We've recently discussed deploying subsets of the functions, but it's not available at the moment - nor can we give a ballpark of if/when it might be.
Update Since Firebase CLI release the ability to deploy single functions is available. See yuku's answer.
Solution 4 - Firebase
firebase deploy --only "functions:<fileName>.<functionName>"
example folder structure:
functions
node_modules
index.js
smsNotification.js
...
You can redeploy just a function in a file with
firebase deploy --only "functions:smsNotification.sendChatNotif"
You can redploy all functions in a file with
firebase deploy --only "functions:smsNotification"
