Functions

function connectFunctionsEmulator

connectFunctionsEmulator: (
    functionsInstance: Functions,
    host: string,
    port: number
) => void;

Modify this instance to communicate with the Cloud Functions emulator.
Note: this must be called before this instance has been used to do any operations.
Parameter host
The emulator host (ex: localhost)
Parameter port
The emulator port (ex: 5001)

function getFunctions

getFunctions: (app?: FirebaseApp, regionOrCustomDomain?: string) => Functions;

Returns a Functions instance for the given app.
Parameter app
The @firebase/app#FirebaseApp to use.
Parameter regionOrCustomDomain
one of: a) The region the callable functions are located in (ex: us-central1) b) A custom domain hosting the callable functions (ex: https://mydomain.com)

    ResponseData = unknown,
    StreamData = unknown
>(
    functionsInstance: Functions,
    name: string,
    options?: HttpsCallableOptions
) => HttpsCallable<RequestData, ResponseData, StreamData>;

Returns a reference to the callable HTTPS trigger with the given name.
Parameter name
The name of the trigger.

Classes

class FunctionsError

class FunctionsError extends FirebaseError {}

An error returned by the Firebase Functions client SDK.
See FunctionsErrorCode for full documentation of codes.
Modifiers
- @public

constructor

constructor(code: FunctionsErrorCodeCore, message?: string, details?: {});

Constructs a new instance of the FunctionsError class.

property details

readonly details?: {};

Additional details to be converted to JSON and included in the error response.

Interfaces

interface Functions

interface Functions {}

A Functions instance.
Modifiers
- @public

property app

app: FirebaseApp;

The @firebase/app#FirebaseApp this Functions instance is associated with.

property customDomain

customDomain: string | null;

A custom domain hosting the callable Cloud Functions. ex: https://mydomain.com

property region

region: string;

The region the callable Cloud Functions are located in. Default is us-central-1.

interface HttpsCallable

interface HttpsCallable<
    RequestData = unknown,
    ResponseData = unknown,
    StreamData = unknown
> {}

A reference to a "callable" HTTP trigger in Cloud Functions.
Parameter data
Data to be passed to callable function.
Modifiers
- @public

property stream

stream: (
    data?: RequestData | null,
    options?: HttpsCallableStreamOptions
) => Promise<HttpsCallableStreamResult<ResponseData, StreamData>>;

call signature

(data?: RequestData | null): Promise<HttpsCallableResult<ResponseData>>;

interface HttpsCallableOptions

interface HttpsCallableOptions {}

An interface for metadata about how calls should be executed.
Modifiers
- @public

property limitedUseAppCheckTokens

limitedUseAppCheckTokens?: boolean;

If set to true, uses a limited-use App Check token for callable function requests from this instance of Functions. You must use limited-use tokens to call functions with replay protection enabled. By default, this is false.

property timeout

timeout?: number;

Time in milliseconds after which to cancel if there is no response. Default is 70000.

interface HttpsCallableResult

interface HttpsCallableResult<ResponseData = unknown> {}

An HttpsCallableResult wraps a single result from a function call.
Modifiers
- @public

property data

readonly data: ResponseData;

Data returned from callable function.

interface HttpsCallableStreamOptions

interface HttpsCallableStreamOptions {}

An interface for metadata about how a stream call should be executed.
Modifiers
- @public

property limitedUseAppCheckTokens

limitedUseAppCheckTokens?: boolean;

If set to true, uses a limited-use App Check token for callable function requests from this instance of Functions. You must use limited-use tokens to call functions with replay protection enabled. By default, this is false.

property signal

signal?: AbortSignal;

An AbortSignal that can be used to cancel the streaming response. When the signal is aborted, the underlying HTTP connection will be terminated.

interface HttpsCallableStreamResult

interface HttpsCallableStreamResult<ResponseData = unknown, StreamData = unknown> {}

An HttpsCallableStreamResult wraps a single streaming result from a function call.
Modifiers
- @public

property data

readonly data: Promise<ResponseData>;

property stream

readonly stream: AsyncIterable<StreamData>;

Type Aliases

type FunctionsErrorCode

type FunctionsErrorCode = `functions/${FunctionsErrorCodeCore}`;

The set of Firebase Functions status codes. The codes are the same at the ones exposed by gRPC here: https://github.com/grpc/grpc/blob/master/doc/statuscodes.md
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.
