Functions Classes Class Description HttpsError An explicit error that can be thrown from a handler to send an error to the client that called the function. Interfaces Interface Description CallableContext The interface for metadata for the API as passed to the handler. Request An express request with the wire format representation of the request body. Type Aliases Type Alias Description FunctionsErrorCode The set of Firebase Functions status codes. The codes are the same at the ones exposed by gRPC. https.onCall()Declares a callable method for clients to call using a Firebase SDK.
Signature:
export declare function onCall(handler: (data: any, context: CallableContext) => any | Promise<any>): HttpsFunction & Runnable<any>;
Returns:
HttpsFunction & Runnable<any>
https.onRequest()Handle HTTP requests.
Signature:
export declare function onRequest(handler: (req: Request, resp: express.Response) => void | Promise<void>): HttpsFunction;
Returns:
https.FunctionsErrorCodeThe set of Firebase Functions status codes. The codes are the same at the ones exposed by gRPC.
Possible values:
cancelled: The operation was cancelled (typically by the caller).
unknown: Unknown error or an error from a different error domain.
invalid-argument: Client specified an invalid argument. Note that this differs from failed-precondition. invalid-argument indicates arguments that are problematic regardless of the state of the system (e.g. an invalid field name).
deadline-exceeded: Deadline expired before operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire.
not-found: Some requested document was not found.
already-exists: Some document that we attempted to create already exists.
permission-denied: The caller does not have permission to execute the specified operation.
resource-exhausted: Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
failed-precondition: Operation was rejected because the system is not in a state required for the operation's execution.
aborted: The operation was aborted, typically due to a concurrency issue like transaction aborts, etc.
out-of-range: Operation was attempted past the valid range.
unimplemented: Operation is not implemented or not supported/enabled.
internal: Internal errors. Means some invariants expected by underlying system has been broken. If you see one of these errors, something is very broken.
unavailable: The service is currently unavailable. This is most likely a transient condition and may be corrected by retrying with a backoff.
data-loss: Unrecoverable data loss or corruption.
unauthenticated: The request does not have valid authentication credentials for the operation.
