# Upgrading to CDKTF Version 0.13

> Introducing namespaces for generated providers

0.13 includes performance improvements to generated providers. Instead of exporting a flat list of exports
including all supported resources and data sources, we now export each construct and it's associated structures in their own namespace.
Due to this, the way you import constructs from your CDKTF application will change.
For more information regarding this release, and some of the reasonings behind the changes, please check out the [version 0.13 release post.](https://cdk.tf/0.13)

### CDKTF get and compatibility with non-namespaced providers

CDKTF 0.13 is backwards compatible and supports 0.12 generated (and pre-built) non-namespaced providers without
any modifications. However, it will only generate namespaced providers. This means that if you were to generate
a new provider using version 0.13, it will be namespaced. In order to migrate gradually, you may want to check in
the generated provider bindings from version 0.12 to your codebase until you're ready to migrate them.
The next major versions of our pre-built providers after the release of version 0.13 will also become namespaced.
Same rules apply there: as long as you don't upgrade your pre-built providers beyond their current major version,
no changes will be required on your part.

### New way to import constructs

Below is a comparison of pre 0.13 imports vs namespaced based imports introduced in version 0.13,
per supported language:

#### Typescript

Before version 0.13:

```typescript theme={null}
import { Container, Image, DockerProvider } from "@ckdtf/provider-docker";
```

Version 0.13:

```typescript theme={null}
import { Image } from "@cdktf/provider-docker/lib/image";
import { DockerProvider } from "@cdktf/provider-docker/lib/provider";
import { Container } from "@cdktf/provider-docker/lib/container";
```

#### Go

<Note>For Go projects, another important thing to note is that we've also moved our pre-built providers to the `cdktf` Github Organization. You can find more about that change [here](https://github.com/open-constructs/cdk-terrain/issues/2146).</Note>

Before version 0.13:

```go theme={null}
import (
  // ... other imports
  "github.com/cdktf/cdktf-provider-azurerm-go/azurerm"
)

func NewMyStack(/* ... */) cdktf.TerraformStack {
  stack := cdktf.NewTerraformStack(/* ... */)

  azurerm.NewAzurermProvider(/* ... */)
  azurerm.NewNetworkInterface(/* ... */)
}
```

Version 0.13:

```go theme={null}
import (
  // ... other imports
  azurermprovider "github.com/cdktf/cdktf-provider-azurerm-go/azurerm/provider"
  "github.com/cdktf/cdktf-provider-azurerm-go/azurerm/networkinterface"
)

func NewMyStack(/* ... */) cdktf.TerraformStack {
  stack := cdktf.NewTerraformStack(/* ... */)

  azurermprovider.NewAzurermProvider(/* ... */)
  networkinterface.NewNetworkInterface(/* ... */)
}
```

#### Python

Before version 0.13:

```python theme={null}
from cdktf_cdktf_provider_kubernetes import Namespace, Service, Deployment, KubernetesProvider
```

Version 0.13:

```python theme={null}
from cdktf_cdktf_provider_kubernetes.provider import KubernetesProvider
from cdktf_cdktf_provider_kubernetes.namespace import Namespace
from cdktf_cdktf_provider_kubernetes.deployment import Deployment
from cdktf_cdktf_provider_kubernetes.service import Service
```

#### Java

Before version 0.13:

```java theme={null}
import com.hashicorp.cdktf.providers.google.ComputeInstance;
import com.hashicorp.cdktf.providers.google.GoogleProvider;
```

Version 0.13:

```java theme={null}
import com.hashicorp.cdktf.providers.google.compute_instance.ComputeInstance;
import com.hashicorp.cdktf.providers.google.provider.GoogleProvider;
```

#### C\#

Before version 0.13:

```csharp theme={null}
using azurerm;
```

Version 0.13:

```csharp theme={null}
using azurerm.Provider;
using azurerm.VirtualNetwork;
```

### New way to import constructs for the AWS provider

If you've used our AWS provider, you might have noticed that it's already namespaced. However, before
version 0.13, the AWS provider was a special case that we were namespacing by hand. With the release of
version 0.13, we're no longer going to be doing that.

#### Typescript

Before version 0.13:

```typescript theme={null}
import { AwsProvider, cloudfront, acm } from "@cdktf/provider-aws";

class MyStack extends TerraformStack {
  constructor(/* ... */) {
    super(/* ... */);

    new AwsProvider(/* ... */);
    new cloudfront.CloudfrontDistribution(/* ... */);
    new acm.AcmCertificate(/* ... */);
  }
}
```

Version 0.13:

```typescript theme={null}
import { AwsProvider } from "@cdktf/provider-aws/lib/provider";
import { CloudfrontDistribution } from "@cdktf/provider-aws/lib/cloudfront-distribution";
import { AcmCertificate } from "@cdktf/provider-aws/lib/acm-certificate";

class MyStack extends TerraformStack {
  constructor(/* ... */) {
    super(/* ... */);

    new AwsProvider(/* ... */);
    new CloudfrontDistribution(/* ... */);
    new AcmCertificate(/* ... */);
  }
}
```

#### Go

Before version 0.13:

```go theme={null}
import (
  // ... other imports
  "github.com/cdktf/cdktf-provider-aws-go/aws"
)

func NewMyStack(/* ... */) cdktf.TerraformStack {
  stack := cdktf.NewTerraformStack(/* ... */)

  aws.NewAwsProvider(/* ... */)
  aws.NewCloudfrontDistribution(/* ... */)
  aws.NewAcmCertificate(/* ... */)
}
```

Version 0.13:

```go theme={null}
import (
  // ... other imports
  "github.com/cdktf/cdktf-provider-aws-go/aws/cloudfrontdistribution"
  "github.com/cdktf/cdktf-provider-aws-go/aws/provider"
  "github.com/cdktf/cdktf-provider-aws-go/aws/acmcertificate"

)

func NewMyStack(/* ... */) cdktf.TerraformStack {
  stack := cdktf.NewTerraformStack(/* ... */)

  provider.NewAwsProvider(/* ... */)
  cloudfrontdistribution.NewCloudfrontDistribution(/* ... */)
  acmcertificate.NewAcmCertificate(/* ... */)
}
```

#### Python

Before version 0.13:

```python theme={null}
from cdktf_cdktf_provider_aws import AwsProvider, cloudfront, acm
```

Version 0.13:

```python theme={null}
from cdktf_cdktf_provider_aws.provider import AwsProvider
from cdktf_cdktf_provider_aws.cloudfront_distribution import CloudfrontDistribution
from cdktf_cdktf_provider_aws.acm_certificate import AcmCertificate
```

#### Java

Before version 0.13:

```java theme={null}
import com.hashicorp.cdktf.providers.aws.AwsProvider;
import com.hashicorp.cdktf.providers.aws.cloudfront.CloudfrontDistribution;
import com.hashicorp.cdktf.providers.aws.acm.AcmCertificate;
```

Version 0.13:

```java theme={null}
import com.hashicorp.cdktf.providers.aws.provider.AwsProvider;
import com.hashicorp.cdktf.providers.aws.cloudfront_distribution.CloudfrontDistribution;
import com.hashicorp.cdktf.providers.aws.acm_certificate.AcmCertificate;
```

#### C\#

Before version 0.13:

```csharp theme={null}
using HashiCorp.Cdktf.Providers.Aws;
using HashiCorp.Cdktf.Providers.Aws.Cloudfront;
using HashiCorp.Cdktf.Providers.Aws.Acm;
```
