KrakenD CORS

====

A set of building blocks for instrumenting [KrakenD](http://www.krakend.io) gateways

## Available flavours

1. [mux](github.com/krakendio/krakend-cors/blob/master/mux) Mux based handlers

2. [gin](github.com/krakendio/krakend-cors/blob/master/gin) Gin based handlers

Check the tests and the documentation for more details

## Configuration

You need to add an ExtraConfig section to the configuration to enable the CORS middleware.

At least one option should be defined.

- `allow_origins` list of strings (you can also use a wildcard, leaving it empty allows all origins too)

- `allow_headers` list of strings

- `allow_methods` list of strings

- `expose_headers` list of strings

- `allow_credentials` bool

- `max_age` duration (Ex: "12h", "5m", "3600s", ...)

### Configuration Example

```

  "extra_config": {

    "github_com/devopsfaith/krakend-cors": {

      "allow_origins": [ "http://foobar.com" ],

      "allow_methods": [ "POST", "GET"],

      "max_age": "12h"

    }

  }

  ```

  or leave the defaults (the defaults allows all origins):

  ```

  "extra_config": {

    "github_com/devopsfaith/krakend-cors": {

      "allow_origins": []

    }

  }

  ```
