# Terraform AWS API Gateway Enable CORS

A Terraform module to add an OPTIONS method to allow Cross-Origin Resource
Sharing (CORS) preflight requests.

## Usage

``` hcl
module "cors" {
source = "squidfunk/api-gateway-enable-cors/aws"
version = "0.3.3"

api_id = ""
api_resource_id = ""
}
```

By default, this will create a new `MOCK` endpoint on the provided API Gateway
resource allowing CORS preflight requests for **all methods** and
**all origins** by default. Of course this can be customized using variables
as stated in the next section.
