# Google Cloud Client Libraries for Go

[![GoDoc](https://godoc.org/cloud.google.com/go?status.svg)](https://godoc.org/cloud.google.com/go)

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:

   ```
   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.

**NOTE:** Github repo is a mirror of [https://code.googlesource.com/gocloud](https://code.googlesource.com/gocloud).

> **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

We support the two most recent major versions of Go. If Google App Engine uses
an older version, we support that as well.

## 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
[`option.WithCredentialsFile`](https://godoc.org/google.golang.org/api/option#WithCredentialsFile)
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
[`golang.org/x/oauth2`](https://godoc.org/golang.org/x/oauth2) package to
create an `oauth2.TokenSource`. Then pass
[`option.WithTokenSource`](https://godoc.org/google.golang.org/api/option#WithTokenSource)
to the `NewClient` function:
[snip]:# (auth-ts)
```go
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
```
