Welcome to the ColdBox Swagger Module

This module automatically generates OpenAPI ( fka Swagger ) documenation from your configured application and module routes. This module utilizes the v3.0.2 OpenAPI Specification

System Requirements

• Lucee 5+
• Adobe ColdFusion 2016+

Pre-requisites

To operate, the module requires that SES routing be enabled in your application. For more information read the official documentation.

Install cbSWagger ( via Commandbox )

box install cbSwagger

Note: Omit the box from your command, if you are already in the Commandbox interactive shell

Configure cbSwagger to auto-detect your API Routes

By default, cbSwagger looks for routes beginning with /api/* prefix. By adding a cbSwagger configuration key to your Coldbox configuration, you can add additional metadata to the OpenAPI JSON produced by the module entry point and configure this module for operation.

• routes:array : An array of route prefixes to search for and add to the resulting documentation.
• defaultFormat:string : The default output format of the documentation. Valid options are json and yml.

A full configuration example is provided below:

cbswagger = {
	// The route prefix to search.  Routes beginning with this prefix will be determined to be api routes
	"routes" : [ "api" ],
	// The default output format: json or yml
	"defaultFormat" : "json",
	// Information about your API
	"info"		:{
		// A title for your API
		"title" 			: "My Awesome API",
		// A description of your API
		"description" 		: "This API produces amazing results and data.",
		// A terms of service URL for your API
		"termsOfService"	: "",
		//The contact email address
		"contact" 		:{
			"name": "API Support",
			"url": "http://www.swagger.io/support",
			"email": "[email protected]"
		},
		//A url to the License of your API
		"license": {
			"name": "Apache 2.0",
			"url": "http://www.apache.org/licenses/LICENSE-2.0.html"
		},
		//The version of your API
		"version":"1.0.0"
	},

		}
	],

				"in" 			: "header"
			}
		}
	},

	// A declaration of which security mechanisms can be used across the API.
	// The list of values includes alternative security requirement objects that can be used.
	// Only one of the security requirement objects need to be satisfied to authorize a request.
	// Individual operations can override this definition.
	"security" : [
		{ "APIKey" : [] },
		{ "UserSecurity" : [] }
	]
};

Outputting Documentation (json|yml)

You can visit the API documentation by hitting the /cbSwagger route. This will trigger the default format (json) to be sent to the output.

Format Parameter

You can force the format by using the ?format={format} in the URI. The valid options are json and yml

http://localhost/cbSwagger?format=yml
http://localhost/cbSwagger?format=json
http://localhost/cbSwagger/json
http://localhost/cbSwagger/yml

Handler Introspection & Documentation attributes

cbSwagger will automatically introspect your API handlers provided by your routing configuration. You may provide additional function attributes, which will be picked up and included in your documentation. The content body of these attributes may be provided as JSON, plain text, or may provided a file pointer which will be included as a $ref attribute. Some notes on function attributes:

• Metadata attributes using a response- prefix in the annotation will be parsed as responses. For example @response-200 { "description" : "User successfully updated", "schema" : "/includes/resources/schema.json##user" } would populate the 200 responses node for the given method ( in this case, PUT /api/v1/users/:id ). If the annotation text is not valid JSON or a file pointer, this will be provided as the response description.
• Metadata attributes prefixed with param- will be included as paramters to the method/action. Example: @param-firstname { "type": "string", "required" : "false", "in" : "query" } If the annotation text is not valid JSON or a file pointer, this will be provided as the parameter description and the parameter requirement will be set to false.
• Parameters provided via the route ( e.g. the id in /api/v1/users/:id ) will always be included in the array of parameters as required for the method. Annotations on those parameters may be used to provide additional documentation.
• You may also provide paths to JSON files which describe complex objects which may not be expressed within the attributes themselves. This is ideal to provide an endpoint for parameters and responses If the atttribute ends with .json, this will be included in the generated OpenAPI document as a $ref include.
• Attributes which are not part of the swagger path specification should be prefixed with an x-, x-attributes are an official part of the OpenAPI Specification and may be used to provide additional information for your developers and consumers
• hint attributes, provided as either comment @ annotations or as function body attributes will be treaded as the description for the method
• description due to variances in parsing comment annotations, description annotations must be provided as attributes of the function body. For example, you would use function update( event, rc, prc ) description="Updates a user"{} rather than @description Updates a user

Basic Example:

//(POST) /api/v1/users
function add( event, rc, prc )
	description="Adds a new user"
	parameters="/includes/resources/users.add.parameters.json"
	responses="/includes/resources/users.add.responses.json"
	x-SomeAdditionalInfo="Here is some additional information on this path"
{

	...[ Your code here ]...

}

Example using file pointers:

/**
* @hint Adds a new user
* @x-parameters /includes/resources/users.add.parameters.json##user
* @responses /includes/resources/users.add.responses.json
* @x-SomeAdditionalInfo Here is some additional information on this path
*/
function add( event, rc, prc ){

	...[ Your code here ]...

}

Example using JSON ( + file pointers )

/**
 * @hint Adds a new user
 * @parameters /includes/resources/users.add.parameters.json##user
 * @responses /includes/resources/users.add.responses.json
 * @x-SomeAdditionalInfo Here is some additional information on this path
 * @requestBody {
 * 	"description" : "User to add",
 * 	"required" : true,
 * 	"content" : {
 * 		"application/json" : {
 * 			"schema" : { "$ref" : "/includes/resources/NewUser.json" }
 * 		}
 * 	}
 * }
 */
function add( event, rc, prc ){
}


/**
 * @param-firstname { "schema" : { "type": "string" }, "required" : "false", "in" : "query" }
 * @param-lastname { "schema" : { "type": "string" }, "required" : "false", "in" : "query" }
 * @param-email { "schema" : { "type": "string" }, "required" : "false", "in" : "query" }
 * @response-default { "description" : "User successfully updated", "content" : { "application/json" : { "schema" : { "$ref" : "/includes/resources/schema.json##user" } } } }
 */
function update( event, rc, prc ) description="Updates a user"{
}

Operation Ids

You can influence the operation Ids by adding a displayName to your handler CFC.

component displayName="API.v1.Users"{

}
