Use the Blaze\n[pricing calculator](/pricing#blaze-calculator) to generate a cost estimate\nbased on your projected usage.\n\nThe Cloud Scheduler API must be enabled for your\nproject. It should already be enabled for most Firebase projects; you can\nverify in the [Google Cloud console](https://console.cloud.google.com/).\n\nWrite a scheduled function\n\nIn Cloud Functions for Firebase, scheduling logic resides in your functions code,\nwith no special deploy-time requirements.\nFor example, to clean up inactive user accounts once daily, you could write\na function starting with the following import statements: \n\nNode.js \n\n // The Cloud Functions for Firebase SDK to set up triggers and logging.\n const {onSchedule} = require(\"firebase-functions/v2/scheduler\");\n const {logger} = require(\"firebase-functions\");\n\n // The Firebase Admin SDK to delete inactive users.\n const admin = require(\"firebase-admin\");\n admin.initializeApp();\n\n // The es6-promise-pool to limit the concurrency of promises.\n const PromisePool = require(\"es6-promise-pool\").default;\n // Maximum concurrent account deletions.\n const MAX_CONCURRENT = 3; \n https://github.com/firebase/functions-samples/blob/c4fde45b65fab584715e786ce3264a6932d996ec/Node/delete-unused-accounts-cron/functions/index.js#L20-L31\n\nPython \n\n # The Cloud Functions for Firebase SDK to set up triggers and logging.\n from firebase_functions import scheduler_fn\n\n # The Firebase Admin SDK to delete users.\n import firebase_admin\n from firebase_admin import auth\n\n firebase_admin.initialize_app() \n https://github.com/firebase/functions-samples/blob/c4fde45b65fab584715e786ce3264a6932d996ec/Python/delete-unused-accounts-cron/functions/main.py#L19-L26\n\nThen, you could use `onSchedule` to start a Cloud Scheduler task: \n\nNode.js \n\n // Run once a day at midnight, to clean up the users\n // Manually run the task here https://console.cloud.google.com/cloudscheduler\n exports.accountcleanup = onSchedule(\"every day 00:00\", async (event) =\u003e {\n // Fetch all user details.\n const inactiveUsers = await getInactiveUsers();\n\n // Use a pool so that we delete maximum `MAX_CONCURRENT` users in parallel.\n const promisePool = new PromisePool(\n () =\u003e deleteInactiveUser(inactiveUsers),\n MAX_CONCURRENT,\n );\n await promisePool.start();\n\n logger.log(\"User cleanup finished\");\n }); \n https://github.com/firebase/functions-samples/blob/c4fde45b65fab584715e786ce3264a6932d996ec/Node/delete-unused-accounts-cron/functions/index.js#L35-L49\n\nPython \n\n # Run once a day at midnight, to clean up inactive users.\n # Manually run the task here https://console.cloud.google.com/cloudscheduler\n @scheduler_fn.on_schedule(schedule=\"every day 00:00\")\n def accountcleanup(event: scheduler_fn.ScheduledEvent) -\u003e None:\n \"\"\"Delete users who've been inactive for 30 days or more.\"\"\"\n user_page: auth.ListUsersPage | None = auth.list_users()\n while user_page is not None:\n inactive_uids = [\n user.uid for user in user_page.users if is_inactive(user, timedelta(days=30))\n ]\n auth.delete_users(inactive_uids)\n user_page = user_page.get_next_page() \n https://github.com/firebase/functions-samples/blob/c4fde45b65fab584715e786ce3264a6932d996ec/Python/delete-unused-accounts-cron/functions/main.py#L31-L42\n\nBoth Unix Crontab and App Engine syntax\nare supported by Cloud Scheduler. For example, to use Crontab, do something like this: \n\nNode.js \n\n exports.scheduledFunctionCrontab = onSchedule(\"5 11 * * *\", async (event) =\u003e {\n // ...\n });\n\nPython \n\n @scheduler_fn.on_schedule(schedule=\"5 11 * * *\")\n\n| **Important:** Depending on how you design your scheduling logic, a function may be triggered multiple times, with the next instance running while the previous instance is still executing.\n\nDeploy a scheduled function\n\nWhen you deploy a scheduled function, a scheduler job and an HTTP function\nare created automatically. The Firebase CLI echoes the function name,\nand you can view the job and the function in the\n[Google Cloud console](https://console.cloud.google.com/project/_/cloudscheduler).\nThe topic is named according to the following convention:\n\n**firebase-schedule-\u003cvar translate=\"no\"\u003efunction_name\u003c/var\u003e-\u003cvar translate=\"no\"\u003eregion\u003c/var\u003e**\n\nFor example:\n\n**firebase-schedule-accountcleanup-us-east1.**\n\nAt the scheduled time, the default compute service account invokes the\nassociated HTTP function. This means that only the associated Cloud Scheduler\njob has permission to run the function.\n| **Important:** Make sure you do not manually delete or modify the function or scheduler job in the console. Doing this could cause errors in the execution of your scheduled function."]]
