Google Cloud Client Libraries for Go

Go packages for Google Cloud Platform services.

Installation

go get cloud.google.com/go/firestore@latest # Replace firestore with the package you want to use.

NOTE: Some of these packages are under development, and may occasionally make backwards-incompatible changes.

Supported APIs

For an updated list of all of our released APIs please see our reference docs.

Go Versions Supported

Our libraries are compatible with the two most recent major Go releases, the same policy the Go programming language follows. This means the currently supported versions are:

Go 1.22
Go 1.23

Authorization

By default, each API will use Google Application Default Credentials for authorization credentials used in calling the API endpoints. This will allow your application to run in many environments without requiring explicit configuration.

client, err := storage.NewClient(ctx)

To authorize using a JSON key file, pass option.WithCredentialsFile to the NewClient function of the desired package. For example:

client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/keyfile.json"))

You can exert more control over authorization by using the credentials package to create an auth.Credentials. Then pass option.WithAuthCredentials to the NewClient function:

creds := ...
client, err := storage.NewClient(ctx, option.WithAuthCredentials(creds))
