Go packages for Google Cloud Platform services.
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.
For an updated list of all of our released APIs please see our reference docs.
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 1.23
- Go 1.24
By default, each client library will use Application Default Credentials (ADC) to automatically configure the credentials used in calling the API endpoint. When using the libraries in a Google Cloud Platform environment such as Compute Engine, Kubernetes Engine, or App Engine, no additional authentication steps are necessary. See Authentication methods at Google and Authenticate for using client libraries for more information.
client, err := storage.NewClient(ctx)For applications running elsewhere, such as your local development environment,
you can use the gcloud auth application-default login command from the
Google Cloud CLI to set user credentials in
your local filesystem. Application Default Credentials will automatically detect
these credentials. See Set up ADC for a local development
environment
for more information.
Alternately, you may need to provide an explicit path to your credentials. To authenticate
using a service account
key file, either set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path
to your key file, or programmatically 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 even more control over authentication by using the
credentials package to
create an auth.Credentials.
Then pass option.WithAuthCredentials
to the NewClient function:
creds, err := credentials.DetectDefault(&credentials.DetectOptions{...})
...
client, err := storage.NewClient(ctx, option.WithAuthCredentials(creds))Contributions are welcome. Please, see the CONTRIBUTING document for details.
