# Google Cloud Client Libraries for Go
2021-01-13 10:19:05 +00:00
[](https://pkg.go.dev/cloud.google.com/go)
2019-11-07 19:05:39 +00:00
Go packages for [Google Cloud Platform ](https://cloud.google.com ) services.
``` go
import "cloud.google.com/go"
```
To install the packages on your system, *do not clone the repo* . Instead:
1. Change to your project directory:
2021-07-15 09:56:59 +00:00
```bash
2019-11-07 19:05:39 +00:00
cd /my/cloud/project
```
1. Get the package you want to use. Some products have their own module, so it's
best to `go get` the package(s) you want to use:
```
$ go get cloud.google.com/go/firestore # Replace with the package you want to use.
```
**NOTE:** Some of these packages are under development, and may occasionally
make backwards-incompatible changes.

> **Alpha status**: the API is still being actively developed. As a
> result, it might change in backward-incompatible ways and is not recommended
> for production use.
>
> **Beta status**: the API is largely complete, but still has outstanding
> features and bugs to be addressed. There may be minor backwards-incompatible
> changes where necessary.
>
> **Stable status**: the API is mature and ready for production use. We will
> continue addressing bugs and feature requests.

## [Go Versions Supported](#supported-versions)
2019-11-07 19:05:39 +00:00
2020-09-16 22:44:08 +00:00
We currently support Go versions 1.11 and newer.
2019-11-07 19:05:39 +00:00
## Authorization
By default, each API will use [Google Application Default Credentials ](https://developers.google.com/identity/protocols/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.
[snip]:# (auth)
```go
client, err := storage.NewClient(ctx)
```
To authorize using a
[JSON key file ](https://cloud.google.com/iam/docs/managing-service-account-keys ),
pass
2020-03-12 16:11:27 +00:00
[`option.WithCredentialsFile` ](https://pkg.go.dev/google.golang.org/api/option#WithCredentialsFile )
2019-11-07 19:05:39 +00:00
to the `NewClient` function of the desired package. For example:
[snip]:# (auth-JSON)
```go
client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/keyfile.json"))
```
You can exert more control over authorization by using the
2020-03-12 16:11:27 +00:00
[`golang.org/x/oauth2` ](https://pkg.go.dev/golang.org/x/oauth2 ) package to
2019-11-07 19:05:39 +00:00
create an `oauth2.TokenSource` . Then pass
2020-03-12 16:11:27 +00:00
[`option.WithTokenSource` ](https://pkg.go.dev/google.golang.org/api/option#WithTokenSource )
2019-11-07 19:05:39 +00:00
to the `NewClient` function:
[snip]:# (auth-ts)
```go
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
```
