# Reusing template code

To reuse code across different Coder templates, such as common scripts or
resource definitions, we suggest using
[Terraform Modules](https://developer.hashicorp.com/terraform/language/modules).

You can store these modules externally from your Coder deployment, like in a git
repository or a Terraform registry. This example shows how to reference a module
from your template:

```tf
data "coder_workspace" "me" {}

module "coder-base" {
  source = "github.com/my-organization/coder-base"

  # Modules take in variables and can provision infrastructure
  vpc_name            = "devex-3"
  subnet_tags         = { "name": data.coder_workspace.me.name }
  code_server_version = 4.14.1
}

resource "coder_agent" "dev" {
  # Modules can provide outputs, such as helper scripts
  startup_script=&lt;
