firebase deploy --remove functions or hosting

Old function sticks in firebase when you rename a function after the first deployment

Deploy this function:

exports.helloFn1 = functions.https.onRequest((request, response) => {
    response.send("Hello from Fn1!");
});

call, and then edit the index.js and change it to:

exports.helloFn2 = functions.https.onRequest((request, response) => {
    response.send("Hello from Fn2!");
});

firebase deploy --only functions

In the firebase console, both functions is there, with no option to delete it.

You can delete it in the cloud console https://console.cloud.google.com but admin will be done from the deployment point of view? Or how is the plan to deploy functions by name from different places?

Right now there’s a known issue where removing the function from your deployed file(s) (e.g. index.js) doesn’t remove the function. See #982 for more details.

Short version:

• firebase deploy --only functions will tell you that it will remove functions, but not actually do so. Run this to know what will be removed.
• firebase deploy --only functions --force will remove the noted functions, but will not ask for confirmation. This will actually delete the removed (from code) functions.

(Be sure you’re on the latest firebase-tools as well!)

What @mbleigh had meant is that if the functions are no longer in functions/index.js when you deploy (because you deleted or commented out the code), then it will be deleted. If that is not working, then go to https://cloud.google.com/console/functions/list, click on the three dots to right of the function you’d like to delete to expand the menu, then click on “delete”. Please reopen this issue if you’re still experiencing problems.
