How to add version in cloud function for firebase
One way of doing is this to make your own path handler. Of course, you can use express but I chose not to use it just for this.
exports.getUsers = functions.https.onRequest((request, response) => {
const path = request.path; // '/getUsers/v2'
const version = path.split('/')[2]; // ['', 'getUsers', 'v2']
switch ( version ) {
case 'v1': // Handle for v1;
break;
case 'v2': // Handle for v2;
break;
}
});
This will expose your endpoint till https://xyz.cloudfunctions.net/getUsers
but for trailing versions or any other stuff in url, you can use a handler like this.
There is no built-in versioning for Cloud Functions. The closest you can get on the default URLs is writing the version into the function name: getUsers_v2
.
If you're using Firebase Hosting to give friendly URLs to your Cloud Functions, you can of course map each individual function to the URL you want.
